Additional Definitions. 14 | 15 | As used herein, "this License" refers to version 3 of the GNU Lesser 16 | General Public License, and the "GNU GPL" refers to version 3 of the GNU 17 | General Public License. 18 | 19 | "The Library" refers to a covered work governed by this License, 20 | other than an Application or a Combined Work as defined below. 21 | 22 | An "Application" is any work that makes use of an interface provided 23 | by the Library, but which is not otherwise based on the Library. 24 | Defining a subclass of a class defined by the Library is deemed a mode 25 | of using an interface provided by the Library. 26 | 27 | A "Combined Work" is a work produced by combining or linking an 28 | Application with the Library. The particular version of the Library 29 | with which the Combined Work was made is also called the "Linked 30 | Version". 31 | 32 | The "Minimal Corresponding Source" for a Combined Work means the 33 | Corresponding Source for the Combined Work, excluding any source code 34 | for portions of the Combined Work that, considered in isolation, are 35 | based on the Application, and not on the Linked Version. 36 | 37 | The "Corresponding Application Code" for a Combined Work means the 38 | object code and/or source code for the Application, including any data 39 | and utility programs needed for reproducing the Combined Work from the 40 | Application, but excluding the System Libraries of the Combined Work. 41 | 42 | 1. Exception to Section 3 of the GNU GPL. 43 | 44 | You may convey a covered work under sections 3 and 4 of this License 45 | without being bound by section 3 of the GNU GPL. 46 | 47 | 2. Conveying Modified Versions. 48 | 49 | If you modify a copy of the Library, and, in your modifications, a 50 | facility refers to a function or data to be supplied by an Application 51 | that uses the facility (other than as an argument passed when the 52 | facility is invoked), then you may convey a copy of the modified 53 | version: 54 | 55 | a) under this License, provided that you make a good faith effort to 56 | ensure that, in the event an Application does not supply the 57 | function or data, the facility still operates, and performs 58 | whatever part of its purpose remains meaningful, or 59 | 60 | b) under the GNU GPL, with none of the additional permissions of 61 | this License applicable to that copy. 62 | 63 | 3. Object Code Incorporating Material from Library Header Files. 64 | 65 | The object code form of an Application may incorporate material from 66 | a header file that is part of the Library. You may convey such object 67 | code under terms of your choice, provided that, if the incorporated 68 | material is not limited to numerical parameters, data structure 69 | layouts and accessors, or small macros, inline functions and templates 70 | (ten or fewer lines in length), you do both of the following: 71 | 72 | a) Give prominent notice with each copy of the object code that the 73 | Library is used in it and that the Library and its use are 74 | covered by this License. 75 | 76 | b) Accompany the object code with a copy of the GNU GPL and this license 77 | document. 78 | 79 | 4. Combined Works. 80 | 81 | You may convey a Combined Work under terms of your choice that, 82 | taken together, effectively do not restrict modification of the 83 | portions of the Library contained in the Combined Work and reverse 84 | engineering for debugging such modifications, if you also do each of 85 | the following: 86 | 87 | a) Give prominent notice with each copy of the Combined Work that 88 | the Library is used in it and that the Library and its use are 89 | covered by this License. 90 | 91 | b) Accompany the Combined Work with a copy of the GNU GPL and this license 92 | document. 93 | 94 | c) For a Combined Work that displays copyright notices during 95 | execution, include the copyright notice for the Library among 96 | these notices, as well as a reference directing the user to the 97 | copies of the GNU GPL and this license document. 98 | 99 | d) Do one of the following: 100 | 101 | 0) Convey the Minimal Corresponding Source under the terms of this 102 | License, and the Corresponding Application Code in a form 103 | suitable for, and under terms that permit, the user to 104 | recombine or relink the Application with a modified version of 105 | the Linked Version to produce a modified Combined Work, in the 106 | manner specified by section 6 of the GNU GPL for conveying 107 | Corresponding Source. 108 | 109 | 1) Use a suitable shared library mechanism for linking with the 110 | Library. A suitable mechanism is one that (a) uses at run time 111 | a copy of the Library already present on the user's computer 112 | system, and (b) will operate properly with a modified version 113 | of the Library that is interface-compatible with the Linked 114 | Version. 115 | 116 | e) Provide Installation Information, but only if you would otherwise 117 | be required to provide such information under section 6 of the 118 | GNU GPL, and only to the extent that such information is 119 | necessary to install and execute a modified version of the 120 | Combined Work produced by recombining or relinking the 121 | Application with a modified version of the Linked Version. (If 122 | you use option 4d0, the Installation Information must accompany 123 | the Minimal Corresponding Source and Corresponding Application 124 | Code. If you use option 4d1, you must provide the Installation 125 | Information in the manner specified by section 6 of the GNU GPL 126 | for conveying Corresponding Source.) 127 | 128 | 5. Combined Libraries. 129 | 130 | You may place library facilities that are a work based on the 131 | Library side by side in a single library together with other library 132 | facilities that are not Applications and are not covered by this 133 | License, and convey such a combined library under terms of your 134 | choice, if you do both of the following: 135 | 136 | a) Accompany the combined library with a copy of the same work based 137 | on the Library, uncombined with any other library facilities, 138 | conveyed under the terms of this License. 139 | 140 | b) Give prominent notice with the combined library that part of it 141 | is a work based on the Library, and explaining where to find the 142 | accompanying uncombined form of the same work. 143 | 144 | 6. Revised Versions of the GNU Lesser General Public License. 145 | 146 | The Free Software Foundation may publish revised and/or new versions 147 | of the GNU Lesser General Public License from time to time. Such new 148 | versions will be similar in spirit to the present version, but may 149 | differ in detail to address new problems or concerns. 150 | 151 | Each version is given a distinguishing version number.

95 | ``` 96 | 97 | 为了应对不同的应用场景，开发者可以通过配置`options`参数来选择使用浏览器插件或者NasNano钱包来完成支付。 这里要用到的参数是 `qrcode.showQRCode` 和 `extension.openExtension`。 98 | 这两个参数的效果如下： 99 | * 参数`showQRCode`决定是否显示二维码信息。不论是PC端还是移动端， 当`showQRCode = true`， 页面上都会弹出二维码信息。 100 | * 参数`openExtension`决定是否使用浏览器插件支付。如果设置`openExtension = true`， 则会尝试通过浏览器插件来完成支付；此时如果插件未安装， 则会通过alert提醒用户安装插件。 在移动端， `openExtension` 参数无效。 101 | * 如果是在移动端发起交易，NebPay都会尝试跳转NasNano完成支付，如果未安装NasNano则会出现下载提醒。 102 | 103 | *** 104 | 105 | ##### pay 106 | 发起普通交易支付，指定转账地址和金额。 107 | 108 | ``` 109 | pay(to, value, options) 110 | ``` 111 | 112 | ###### 参数说明： 113 | 114 | - `to` 转账目的地址 115 | 116 | - `value` 转账数额，单位为nas。（wei是Nas的最小单位，1 Nas = 1e18 wei） 117 | 118 | - `options` 参见[options](#options) 119 | 120 | ###### 返回值 121 | 122 | - `serialNumber` 交易流水号，用于查询交易信息 123 | 124 | *** 125 | 126 | ##### nrc20pay 127 | 128 | 发起星云代币交易支付，指定交易代币名称，转账地址和金额。 129 | 130 | ``` 131 | nrc20pay(currency, to, value, options) 132 | ``` 133 | 134 | ###### 参数说明： 135 | 136 | - `currency` NRC20代币符号, 即代币简称, 等同于options.nrc20.symbol 137 | 138 | - `to` 转账目的地址，该地址为nebulas钱包地址 139 | 140 | - `value` 转账数额，单位为 NRC20 token 141 | 142 | - `options` 必须指定代币的小数点位数和代币合约地址，另外可指定代币名称、符号。 143 | 144 | ```js 145 | options = { 146 | //nrc20参数介绍 147 | nrc20: { 148 | address: "", //NRC20 代币的合约地址 149 | decimals: 0, //代币小数点位数, 决定了代币的最小单位 150 | name: "", //代币全称, 比如 "Nebulas Token" 151 | symbol: "" //代币简称, 比如 "NAS", "EOS" 152 | } 153 | } 154 | ``` 155 | ###### 返回值 156 | 157 | - `serialNumber` 交易流水号，用于查询交易信息 158 | 159 | *** 160 | 161 | ##### deploy 162 | 163 | 发起部署合约交易，指定合约代码，合约代码类型和参数。**【当前版本暂不支持】** 164 | 165 | ``` 166 | deploy(source, sourceType, args, options) 167 | ``` 168 | 169 | ###### 参数说明： 170 | 171 | - `source` 合约源代码 172 | 173 | - `sourceType` 合约代码类型 174 | 175 | - `args` 合约的初始化函数参数，初始化函数无参数则留空，参数格式为参数数组的JSON字符串，比如`["arg"]` ， `["arg1","arg2"]`。 176 | 177 | - `options` 参见[options](#options) 178 | 179 | ###### 返回值 180 | 181 | - `serialNumber` 交易流水号，用于查询交易信息 182 | 183 | *** 184 | 185 | ##### call 186 | 187 | 发起合约调用交易，指定合约地址，金额，方法名和参数。 188 | 189 | ``` 190 | call(to, value, func, args, options) 191 | ``` 192 | 193 | ###### 参数说明： 194 | 195 | - `to` 合约地址 196 | 197 | - `value` 转账数额，单位为nas。注意value是向合约地址转账，如果合约没有相关的转出函数，则转入的Nas将无法转出。 198 | 199 | - `func` 要调用的合约函数名 200 | 201 | - `args` 调用的函数参数，格式为参数数组的JSON字符串，比如`["arg"]` ， `["arg1","arg2"]`。 202 | 203 | - `options` 参见[options](#options) 204 | 205 | ###### 返回值 206 | 207 | - `serialNumber` 交易流水号，用于查询交易信息 208 | 209 | *** 210 | 211 | ##### queryPayInfo 212 | 查询交易信息。 213 | 214 | ``` 215 | queryPayInfo(serialNumber,options) 216 | ``` 217 | 218 | ###### 参数说明： 219 | 220 | - `serialNumber` 交易序列号，使用上面介绍的接口发送交易后会返回该交易的序列号，是一个32字节随机数。钱包App会将交易结果会上传到交易查询服务器，Dapp端用 `queryPayInfo(serialNumber)` 来查询交易结果信息。 221 | - `options` 对于`queryPayInfo`接口, options 主要用来指定交易查询服务器. 222 | 223 | ###### 返回值: 224 | `queryPayInfo`会返回一个`Promise`对象. 225 | 226 | ```js 227 | var options = {callback: NebPay.config.testnetUrl} //指定查询服务器 228 | nebPay.queryPayInfo(serialNumber, options) 229 | .then(function (resp) { 230 | console.log(resp); 231 | }) 232 | .catch(function (err) { 233 | console.log(err); 234 | }); 235 | ``` 236 | **注意:** 我们提供的查询服务器有查询频率限制, 不得超过20次/分钟, 所以查询周期在 5-10s为宜. 237 | 238 | #### 交易返回信息的处理 239 | 跳转钱包APP发送交易时，钱包App无法直接返回消息给Dapp页面，所以App会将交易信息发送到一个交易查询服务器。 240 | Dapp端需要记录发送交易时返回的序列号`serialNumber`，然后使用`queryPayInfo`接口去查询该交易的序列号以获取交易信息. 241 | 242 | 浏览器插件则相对灵活一些, 它可以直接发送消息给页面。使用浏览器插件发送交易时，浏览器插件可以直接返回交易结果给Dapp页面。 243 | 所以除了可以通过`serialNumber`查询交易结果，Dapp端也可以指定一个`listener(serialNumber, result)`函数来接收并处理交易返回信息。 244 | 245 | **注意：** NebPay并不直接决定交易发送到什么网络(主网/测试网/本地网络), 只是把交易信息发给插件或手机App, 由后者决定使用哪个网络。 246 | NebPay 指定的 callback 是交易查询服务器地址, callback只是告诉钱包App将发送交易后的(serialNumber,txHash)注册到哪个服务器以供查询, 并不能决定交易发送到主网还是测试网。 247 | 248 | #### 交易返回信息 249 | 250 | `queryPayInfo` 查询到的交易返回信息为JSON字符串, 反序列化得到的js 对象。其格式为如下所示。 251 | Dapp页面应该判断`code === 0`, 然后判断`data.status === 1`以确保交易被打包上链。 252 | 253 | ```json 254 | //查询失败 255 | { 256 | "code": 1, 257 | "data": {}, 258 | "msg": "payId ZBTSkk74dB4tPJI9J8FDFMu270h7yaut get transaction error" 259 | }, 260 | //查询成功 261 | { 262 | "code": 0, 263 | "data": { 264 | "data": null, 265 | "contractAddress": "", 266 | "type": "binary", 267 | "nonce": 136, 268 | "gasLimit": "30000", 269 | "gasUsed": "20000", 270 | "chainId": 1001, 271 | "from": "n1JmhE82GNjdZPNZr6dgUuSfzy2WRwmD9zy", 272 | "to": "n1JmhE82GNjdZPNZr6dgUuSfzy2WRwmD9zy", 273 | "value": "1000000000000000000", 274 | "hash": "f9549a5c01f50f372607b9fd29bf15d483246578f6cc7008d6e2a537920802e6", 275 | "gasPrice": "1000000", 276 | "status": 1, 277 | "timestamp": 1525508076 278 | }, 279 | "msg": "success" 280 | } 281 | ``` 282 | 283 | 对于浏览器插件，如果指定了`listener`函数，发送交易后如果有返回信息，则会调用`listener`来处理，返回的信息如下： 284 | 285 | **注意：** Listener函数需要有两个参数`function listener(serialNumber, result)` 286 | ```json 287 | //用户拒绝交易, 这会返回错误信息(字符串) 288 | "Error: Transaction rejected by user 289 | 290 | //成功发送交易， 291 | { 292 | "txhash": "a333288574df47b411ca43ed656e16c99c0af98fa3ab14647ce1ad66b45d43f1", 293 | "contract_address": "" 294 | } 295 | ``` 296 | 297 | ###使用NebPay的交易处理流程如下: 298 | 299 | ![](flow_chart.png) 300 | 301 | ### NebPay 的使用效果示例 302 | 这里有个使用nebPay的例子可以参考: [SuperDictionary](https://yupnano.github.io/SuperDictionary/) ，[GitHub链接](https://github.com/15010159959/super-dictionary) 303 | 304 | SuperDictionary 的使用过程可参见以下视频： 305 | 306 | Youtube: 307 | - [Nebulas Dapp Using NebPay SDK on PC](https://youtu.be/FSFZqoUIT8A) 308 | - [Nebulas Dapp Using NebPay SDK on mobile](https://youtu.be/Cjlo9KKwlNE) 309 | 310 | 国内视频: 311 | - [[星云链]如何在Dapp中使用NebPay SDK ](https://www.bilibili.com/video/av23217213/) 312 | 313 | ### 提示 314 | 在开发Dapp页面时，如果不想使用NebPay，或者需要处理交易之外的其他消息，则可以使用[neb.js](https://github.com/nebulasio/neb.js)直接访问星云链。 315 | -------------------------------------------------------------------------------- /examples/example.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 156 | 166 | 167 | 168 |

While using NebPay in your Dapp page, you can send transaction throw desktop browser extension and mobile wallet App. 5 | 6 | ### API introduction 7 | 8 | The APIs provided by NebPay SDK are as flows： 9 | 10 | | API | Introduction | 11 | | :---------------------------- | :---------------------------------- | 12 | | [pay](#pay) | Ordinary transactions between users | 13 | | [nrc20pay](#nrc20pay) | NRC20 token transactions | 14 | | [deploy](#deploy) | Deploy a smart contract | 15 | | [call](#call) | Call a smart contract function | 16 | | [queryPayInfo](#querypayinfo) | query a transaction result | 17 | 18 | The first four APIs above are correspond to [SendTransaction](https://github.com/nebulasio/wiki/blob/master/rpc_admin.md#sendtransaction) API, and just refined the usage scenario of `SendTransaction`. 19 | simulateCall is correspond to [Call](https://github.com/nebulasio/wiki/blob/master/rpc.md#call) API, which is only used for interactions with browser extension, and is not supported by mobile wallet App. 20 | 21 | 22 | ### How to use NebPay 23 | While developing your Dapp, if you want to use NebPay SDK to handle transaction, you need to include `nebPay.js` into your Dapp page. And then you can use NebPay module to send transactions. 24 | 25 | When users using your Dapp whit desktop browsers (chrome), NebPay will call the browser plugin to process the transaction. And when your Dapp is used on mobile phone, NebPay will jump to the wallet App to process the transaction. 26 | 27 | Here is an example of using NebPay in you Dapp. Please refer to `examples/example.html` for more information. 28 | 29 | ```html 30 | 31 | 52 | ``` 53 | 54 | #### Introduction of API & Parameters 55 | 56 | ##### options 57 | 58 | NebPay payment APIs has a common parameter `options`. And here is a detailed introduction of it. 59 | 60 | ```js 61 | var options = { 62 | gasLimit: "2000000", //you can customize the gasLimit and gasPrice 63 | gasPrice: "20000000000", 64 | 65 | goods: { //Description of this commodity being traded 66 | name: "", //name of commodity 67 | desc: "", //description 68 | orderId: "", //order ID 69 | ext: "" //extended field 70 | }, 71 | qrcode: { 72 | showQRCode: false, //Whether to display QR code information 73 | container: undefined, //Specifies the canvas container that displays the QR code. 74 | completeTip: undefined, // string of complete payment tip 75 | cancelTip: undefined // string of cancel payment tip 76 | }, 77 | extension: { 78 | openExtension: true //set if need show extension payment mode 79 | }, 80 | mobile: { 81 | showInstallTip: true, 82 | installTip: undefined // string of install NASNano tip 83 | }, 84 | 85 | // callback is the server address that records tx results (the results is uploaded by wallet App) 86 | // we provided tx results query server for testnet and mainnet, and there is a limits to the query frequency.(should less than 20 times per minute) 87 | //callback: NebPay.config.mainnetUrl, //tx result query server for mainnet 88 | callback: NebPay.config.testnetUrl, //tx result query server for testnet 89 | 90 | // listener： specify a listener function to handle payment feedback message（just used by browser extension, App wallet doesn't support listener） 91 | listener: undefined, 92 | 93 | // if use nrc20pay API, you need to specify nrc20 params like name, address, symbol, decimals 94 | nrc20: undefined, 95 | 96 | // if debug mode, should open testnet nano and reset the callback 97 | debug: false 98 | }; 99 | ``` 100 | In order to deal with different application scenarios, developers can choose to use the browser plugin or NasNano wallet to complete the payment by configuring the `options` parameter. 101 | 102 | The parameters to be used here are `qrcode.showQRCode` and `extension.openExtension`. 103 | The effect of these two parameters is as follows: 104 | * The parameter `showQRCode` determines whether to display the QR code information. Whether it is PC or mobile, when `showQRCode = true`, the QR code information will pop up on the page. 105 | * The parameter `openExtension` determines whether to open the browser plugin. If `openExtension = true`, NebPay will try to complete the transaction through the browser plugin. And if the plugin is not installed, an alert info will be prompted to tell the user to install the plugin. On the mobile side, the `openExtension` parameter is neglected. 106 | * If NebPay is used on the mobile side, it will try to jump to NasNano to complete the payment. If NasNano is not installed, a download reminder will appear. 107 | 108 | *** 109 | 110 | ##### pay 111 | 112 | pay(to, value, options) 113 | 114 | ###### parameters： 115 | 116 | - `to` Destination address of this transfer 117 | 118 | - `value` Transfer amount in nas. 119 | 120 | - `options` Refer to [options](#options) 121 | 122 | ###### return 123 | 124 | - `serialNumber` transaction's serival number, used for query transaction info. 125 | 126 | *** 127 | 128 | ##### nrc20pay 129 | 130 | **[Currently not support for mobile wallet app]** 131 | 132 | ``` 133 | nrc20pay(currency, to, value, options) 134 | ``` 135 | 136 | ###### parameters： 137 | 138 | - `currency` symbol of NRC20 Token, 139 | 140 | - `to` Destination address, which is a Nebulas wallet address 141 | 142 | - `value` Transfer amount, The unit is this NRC20 token. 143 | 144 | - `options` decimals and Token SmartContract address is required, while Token name and symbol is optional。 145 | 146 | ```js 147 | options = { 148 | //nrc20 parameter 149 | nrc20: { 150 | address: "", //contract address of nrc20 151 | decimals: 0, // 152 | name: "", //Token full name, such as "Nebulas Token" 153 | symbol: "" //Token symbol, such as "NAS","EOS". it's the same with "currency" 154 | } 155 | } 156 | ``` 157 | 158 | ###### return 159 | 160 | - `serialNumber` transaction's serival number, used for query transaction info. 161 | 162 | *** 163 | 164 | ##### deploy 165 | 166 | **[Currently not support for mobile wallet app]** 167 | 168 | ``` 169 | deploy(source, sourceType, args, options) 170 | ``` 171 | 172 | ###### parameters： 173 | 174 | - `source` source code of smart contract 175 | 176 | - `sourceType` source type of smart contract 177 | 178 | - `args` initialization parameters of the SmartContract. parameters are in the form of JSON string of the parameters array, such as`["arg"]` , `["arg1","arg2"]`. 179 | 180 | - `options` Refer to [options](#options) 181 | 182 | ###### return 183 | 184 | - `serialNumber` transaction's serival number, used for query transaction info. 185 | 186 | *** 187 | 188 | ##### call 189 | 190 | call(to, value, func, args, options) 191 | 192 | ###### parameters： 193 | 194 | - `to` address of smart contract 195 | 196 | - `value` Transfer amount in nas.

We suggest that you should set the query period to 5~10s. 235 | 236 | #### Dealing with transaction results 237 | 238 | When using wallet App to send tx, wallet App can't return tx result back to Dapp page directly. Hence wallet App will send the tx result to a server. The Dapp side need to record the SerialNumber of a tx, and then use `queryPayInfo` to query the tx result from this server. 239 | 240 | Browser plugins are relatively flexible, it can send messages directly to the page. 241 | When using a browser extension to send tx, the extension can send back tx result directly. 242 | Hence except querying result with `serialNumber`, you can also just specify a `listener(serialNumber, result)` function to handle tx result. 243 | 244 | #### Transaction result message 245 | 246 | The tx result queried by `queryPayInfo` is a JSON string, the format of this JSON is as follows. 247 | You should check `code === 0`, and `data.status === 1` to make sure the transaction is packed on chain. 248 | ```json 249 | //query failed 250 | { 251 | "code": 1, 252 | "data": {}, 253 | "msg": "payId ZBTSkk74dB4tPJI9J8FDFMu270h7yaut get transaction error" 254 | }, 255 | //query succeed 256 | { 257 | "code": 0, 258 | "data": { 259 | "data": null, 260 | "contractAddress": "", 261 | "type": "binary", 262 | "nonce": 136, 263 | "gasLimit": "30000", 264 | "gasUsed": "20000", 265 | "chainId": 1001, 266 | "from": "n1JmhE82GNjdZPNZr6dgUuSfzy2WRwmD9zy", 267 | "to": "n1JmhE82GNjdZPNZr6dgUuSfzy2WRwmD9zy", 268 | "value": "1000000000000000000", 269 | "hash": "f9549a5c01f50f372607b9fd29bf15d483246578f6cc7008d6e2a537920802e6", 270 | "gasPrice": "1000000", 271 | "status": 1, 272 | "timestamp": 1525508076 273 | }, 274 | "msg": "success" 275 | } 276 | ``` 277 | 278 | For browser, if you specified a `listener` as callback function, then it will be called when a result is returned. 279 | 280 | **Note** Listener function has two parameters `function listener(serialNumber, result)` 281 | 282 | The result information is as follows. 283 | ```json 284 | //transaction error, such as user rejected it 285 | "Error: Transaction rejected by user 286 | 287 | //transaction successfully sent 288 | { 289 | "txhash": "a333288574df47b411ca43ed656e16c99c0af98fa3ab14647ce1ad66b45d43f1", 290 | "contract_address": "" 291 | } 292 | ``` 293 | ### The transaction process using NebPay is as folows: 294 | ![](flow_chart.png) 295 | 296 | ### Example of Dapp using NebPay 297 | Here is a Dapp example Using NebPay: [SuperDictionary](https://yupnano.github.io/SuperDictionary/). It’s source code is on [GitHub](https://github.com/15010159959/super-dictionary). 298 | 299 | These videos blow explains the payment process of a Dapp using NebPay both on PC and mobile phone. 300 |
