1 | # PAYJS 小程序支付框架与示例
2 |
3 | 本示例采用了框架 + 示例调用的形式，用于使用 [PAYJS](https://payjs.cn/ref/WDQGQD) 的小程序支付
4 |
5 |
6 | 注：根据微信规范，iOS 系统上不能使用虚拟支付
7 | 注：最低基础库为 2.4.0，请注意修改小程序后台设置中的最低基础库版本和开发者工具中的调试基础库版本
8 |
9 | ## 测试
10 | 克隆本仓库后使用微信开发者工具加载本项目源码，注意在创建项目时将 appid 修改为自己的
11 |
12 | 在 utils/util.js 中
13 |
14 | ```js
15 | // 在下面设置商户号
16 | const mchid = ''
17 |
18 | // 在下面设置密钥
19 | // 特别注意：此项设置应该仅供测试，生产环境下请在后端完成签名，切忌在小程序内暴露商户密钥
20 | const secret = ''
21 | ```
22 |
23 | 这两个部分分别设置为自己的商户号和密钥（不设置的话你测试用的钱结算到我这里我不还）
24 |
25 | ## 生产环境
26 |
27 | ### Step 1
28 |
29 | 在 app.json 文件中加入
30 |
31 | ```json
32 | "navigateToMiniProgramAppIdList": [
33 | "wx959c8c1fb2d877b5"
34 | ]
35 | ```
36 |
37 | ### Step 2
38 |
39 | 将 `components/payjs/*` 整个文件夹复制到你的项目中的相同结构文件夹
40 |
41 | ### Step 3
42 |
43 | 在需要用到支付功能的页面的 `.json` 文件中加入
44 |
45 | ```json
46 | "usingComponents": {
47 | "payjs": "/components/payjs/payjs"
48 | }
49 | ```
50 |
51 | ### Step 4
52 |
53 | 在需要用到支付功能的页面的 `.wxml` 文件**最底端**加入
54 |
55 | ```xml
56 |
57 | ```
58 |
59 | ### Step 5
60 |
61 | 在需要用到支付功能的页面的 `.js` 文件中的 `data` 数据内加入以下三个数据
62 |
63 | ```js
64 | {
65 | orderParams: {}, // 支付发起参数
66 | preparePay: false, // 控制 payjs 组件的创建与销毁
67 | paying: false, // 可选：如需知晓用户是否「已经跳转到了 PAYJS 小程序还未返回」的状态则可通过事件处理函数监听事件内的 paying 数据
68 | }
69 | ```
70 |
71 | 数据名称可以更改，但是更改时请注意保证和上面的 `.wxml` 文件内数据绑定及下面的事件处理函数中保持一致
72 |
73 |
74 | orderParams 用于放置发起支付的参数（必填）
75 | preparePay 用于控制 payjs 支付组件的创建与销毁
76 |
77 |
78 | 在此页面加入四个事件处理函数
79 |
80 | ```js
81 | /**
82 | * 支付成功的事件处理函数
83 | *
84 | * res.detail 为 PAYJS 小程序返回的订单信息
85 | *
86 | * 可通过 res.detail.payjsOrderId 拿到 PAYJS 订单号
87 | * 可通过 res.detail.responseData 拿到详细支付信息
88 | */
89 | bindPaySuccess (res) {
90 | console.log('success', res)
91 | console.log('[支付成功] PAYJS 订单号：', res.detail.payjsOrderId)
92 | this.setData({
93 | orderResults: res.detail,
94 | needRefreshOrderParams: true
95 | })
96 | wx.showModal({
97 | title: '支付成功',
98 | content: 'PAYJS 订单号：' + res.detail.payjsOrderId,
99 | showCancel: false
100 | })
101 | },
102 | /**
103 | * 支付失败的事件处理函数
104 | *
105 | * res.detail.error 为 true 代表传入小组件的参数存在问题
106 | * res.detail.navigateSuccess 代表了是否成功跳转到 PAYJS 小程序
107 | * res.detail.info 可能存有失败的原因
108 | *
109 | * 如果下单成功但是用户取消支付则可在 res.detail.info.payjsOrderId 拿到 payjs 订单号
110 | */
111 | bindPayFail (res) {
112 | console.log('fail', res)
113 | if (res.detail.error) {
114 | console.error('发起支付失败', res.detail.info)

118 | },
119 | /**

130 | },

140 | paying: res.detail.paying
141 | })
142 | }
143 | }
144 |
145 | ```
146 |
147 | ### Step 6
148 |
149 | 为支付页面的支付按钮绑定以下事件
150 |
151 | ```xml
152 |
153 | ```
154 |
155 | ```js
