【Python】钉钉E应用Python版QuickStart

代码已开源，戳这里: https://github.com/YzzHa/eapp-corp-quick-start-python，赠人玫瑰手有余香，采纳的小伙伴们点个star再走呗 O.o

1. 登录验证流程分析，以Node为例

话不多说上代码，以关键代码为例, 部分密匙信息采用***进行占位，请对号入座。代码来自钉钉官方Node版QuickStart

// 获取用户信息 
app.use('/login', function(req, res) {
    // 获取access_token 
    HttpUtils.get("/gettoken", {
        "appkey": config.appkey,
        "appsecret": config.appsecret,
    }, function(err, body) {
        if (!err) {
            var code = req.body.authCode;
            var accessToken = body.access_token;
            //获取用户id 依赖access_token 
            HttpUtils.get("/user/getuserinfo", {
                "access_token": accessToken,
                "code": code,
            }, function(err2, body2) {
                if (!err2) {
                    //获取用户详细信息 依赖userid
                    HttpUtils.get("/user/get", {
                        "access_token": accessToken,
                        "userid": body2.userid,
                    }, function(err3, body3) {
                        console.log(body2, body3);
                        if (!err3) {
                            res.send({
                                // 返回数据格式, 坑位预留
                                result: {
                                    userId: body2.userid,
                                    userName: body3.name
                                }
                            });
                        } else {
                            console.err('获取用户信息失败');
                        }
                        
                    });
                } else {
                    console.err('获取用户id失败');
                }
               
            });
        } else {
            console.err('获取access_token失败');
        }
    });

});

1. https://oapi.dingtalk.com/gettoken 

请求方式: GET（HTTPS），参数 { "appkey":***, "appsecret": ***}

参数说明, E应用密匙对，参考文档: https://open-doc.dingtalk.com/microapp/bgb96b/bcdlg8

// response values
{'errcode': 0, 'access_token': ***, 'errmsg': 'ok', 'expires_in': 7200}

2.  https://oapi.dingtalk.com/user/getuserinfo

请求方式：GET（HTTPS）， 参数{ "access_token":***, "code": ***}

参数说明：access_token~上一步返回Json对象中的access_token， code~小程序前端获取

// authCode E应用获取方式
dd.getAuthCode({
      success: res => {
        console.log(res.authCode)

// response values
{ "userid": "****", "sys_level": 1, "errmsg": "ok", "is_sys": true, "deviceId": "***","errcode": 0 }

返回结果: 参考文档~https://open-doc.dingtalk.com/microapp/serverapi2/clotub

3. https://oapi.dingtalk.com/user/get

请求方式：GET（HTTPS）， 参数{ "access_token":***, "userid": ***}

参数说明：access_token~第一步的access_token， userid~第二步的userid，

预留坑位: 这一步会检查请求IP白名单, 报错信息如下

{
    "errcode": 60020,
    "errmsg": "请参考FAQ：https://open-doc.dingtalk.com/microapp/faquestions/cvbtph。错误原因：访问ip不在白名单之中,request ip=*** corpId(***)"
}

数据返回格式要求，对应钉钉官方E应用前端代码，默认返回data，记得参数需包裹在result中

const data = {
    userId: res.data.result.userId,
    userName: res.data.result.userName
}

this.setData({...data, hideList: false})

2. Python实现方式

入口: run.py， 坑位预留request.json报错的话，替换成request.form

# -*- coding:utf-8 -*-

from flask import Flask, request, jsonify
from login import Login
app = Flask(__name__)

# Registration login event
@app.route('/login', methods=['POST'])
def user_login():
    query = request.json # Set the value to request.form if error is reported

    return jsonify(Login(query['authCode']).get_data())

# Start the service
if __name__ == '__main__':
    app.run(debug=True, host='0.0.0.0', port=5000)

配置文件: config.json

{
    "weburl": "https://oapi.dingtalk.com",
    "app": {
      "appkey": ***,
      "appsecret": ***
    }
}

核心: login.py
