  2 | 
  3 | ## 概述
  4 | 
  5 | 本程序实现了一个服务器，用来接收交易请求，并将请求转发给trade.dll，使其可以通过rest api 被其它程序调用。
  6 | 
  7 | ```
  8 | 注意，注意，注意: 本程序不提供trade.dll文件，仅仅调用该dll库进行交易，并将其封装成rest api使用，
  9 | 我们也不会提供任何trade.dll文件给使用者（关于trade.dll，请自行百度\谷歌）
 10 | 如需技术支持，可以想办法联系我。

 51 | 
 52 | ## 构建
 53 | 
 54 | 本程序使用QT5.9.1开发，使用`restbed`作为web server实现，使用`jsonformoderncpp`作为json序列化和反序列化工具，使用`conan`作为c++依赖库的管理。 请使用兼容`c++11`的编译器编译（这里我使用的vs2015的编译器，理论上mingw应该也可以）
 55 | 
 56 | ### 构建过程
 57 | 
 58 | 1. 安装python
 59 | 2. 安装Conan
 60 | 3. 安装Qt 并配置VS2015 C++ Compiler
 61 | 4. 配置git
 62 | 5. 安装cmake
 63 | 6. 配置git,mingz,cmake命令在系统path中可以调用
 64 | 7. 安装msys2 (openssl编译需要）
 65 | 8. 在msys2中安装perl, cmake
 66 | 
 67 |   ```bash
 68 |   pacman -S perl
 69 |   pacman -S make
 70 |   ```
 71 | 
 72 | 9. 配置conan.conf
 73 | 
 74 |   ```
 75 |   [general]
 76 |   bash_path="c:\msys32\bin\bash"
 77 |   ..
 78 |   [settings_defaults]
 79 |   arch=x86
 80 |   compiler=Visual Studio
 81 |   compiler.version=14
 82 |   compiler.runtime=MTd
 83 |   build_type=Debug
 84 |   os=Windows
 85 |   ```
 86 | 
 87 | 10. 在项目目录下执行
 88 | 
 89 |   ```
 90 |   conan install --build zlib --buildOpenSSL --build asio --build restbed
 91 |   ```
 92 | 
 93 | 然后打开QT Creator编译即可。
 94 | 
 95 | ## 配置
 96 | 
 97 | 我们可以通过配置文件来配置系统，配置文件可以在如下两个地方被放置
 98 | 
 99 | 1. [程序运行目录]/TdxTradeServer.ini
100 | 2. ~/TdxTradeServer/TdxTradeServer.ini ， ~ 代表当前用户的主目录
101 | 
102 | 配置文件Demo
103 | 
104 | ```
105 | bind=10.11.5.175    ; 绑定的ip地址，默认是127.0.0.1
106 | port=10092          ; 绑定的端口
107 | trade_dll_path=D:\\trade_rainx.dll   ;一份可以使用的trade.dll文件
108 | transport_enc_key=4f1cf3fec4c84c84   ; 可选， aes加密秘钥
109 | transport_enc_iv=0c78abc083b011e7    ; 可选， aes加密iv
110 | ```
111 | 
112 | 注意，后面的加密选项为可选，如果`transport_enc_key` 或者 `transport_enc_iv` 不提供的话，将使用明文和`client api`通讯，请注意和`client api`保持一致。 如果您跨机器调用接口，建议使用加密功能，并且，请生成随即密钥和iv, 注意，我们这里`key`和`iv`必须是`16`个字节
113 | 
114 | ## 通讯协议
115 | 
116 | 服务器端通过`restbed`实现了一个webserver, 程序会提供 `http://[your_bind]:[your_port]/api` endpoint, 所有的交互都由客户端通过HTTP `POST`到本endpoint 实现。
117 | 
118 | - 请求的内容(payload)放在Request的Body中
119 | - 应答的内容(payload)放在Response的Body中
120 | - 在非加密的情况下，payload 使用json序列化方式传输
121 | - 在加密情况下，payload 使用 `URLENCODE(BASE64(AES128_CBC(JSON(PAYLOAD))))` 结构加密传输，双方都采用相同方式加密解密
122 | 
123 | 请求的内容结构如下
124 | 
125 | ```json
126 | {
127 |     "func": "one_function",
128 |     "params": {
129 |         "param1": "p1",
130 |         "param2": "p2"
131 |     }
132 | }
133 | ```
134 | 
135 | 应答的结构如下
136 | 
137 | ```json
138 | {
139 |     "success": true,
140 |     "data": {
141 |         ....
142 |     },
143 |     "error": "some errors only appear when success is False"
144 | }
145 | ```
146 | 
147 | ## 测试连通性
148 | 
149 | 假设端口为 19820
150 | 
151 | ```python
152 | In [5]: requests.post("http://127.0.0.1:19820/api", json={"func":"ping"}).text
153 | Out[5]: '{"success":true, "data": "pong"}'
154 | 
155 | In [6]: requests.get("http://127.0.0.1:19820/status").text
156 | Out[6]: '{"reqnum":1,"success":true}'
157 | ```
