一、前置知識

1. 閱讀 企業微信小程序開發文檔

https://developer.work.weixin.qq.com/document/path/92426

2. 企業微信小程序登錄流程

企業微信小程序獲取access_token文檔

3. 微信小程序區別

區分企業微信小程序登錄流程和微信小程序登錄流程不同點。

不同點：
1.企業微信小程序登錄流程和微信小程序登錄流程不一樣，獲取的用戶信息也不一樣。
2.企業微信小程序登錄流程需要將企業微信小程序先發布上傳嗎，審核通過后，將企業微信小程序與企業應用進行綁定后，獲取該應用的agentSecret和corpId去獲取AccessToken，然后，通過AccessToken和code獲取用戶信息，最后通過獲取的userid在調用通訊錄接口獲取該用戶的詳細信息。
3.開發階段：可以使用企業微信提供的測試應用的agentSecret和corpId

二、前端部分

2.1. 調用登錄接口

執行流程會從前端到后端：
前端調用騰訊企業微信登錄接口api
登錄api開發文檔：https://developer.work.weixin.qq.com/document/path/91506
uniapp項目小程序項目寫法：

// 企業微信下程序登錄的方法login() {wx.qy.login({success: function(res) {// 調用成功，會返回codeconsole.log("res", res)}})},

返回的報文：

{code: "VFUfreDIauQszKQy5mZgRC3aaMijd7DM-xnOcZW3LVE", errMsg: "qy__login:ok"}

小程序項目寫法：

//app.js App({onLaunch: function() {wx.qy.login({success: function(res) {if (res.code) {//發起網絡請求wx.request({url: 'https://test.com/onLogin',data: {code: res.code}})} else {console.log('登錄失敗！' + res.errMsg)}}});} })

2.2. 請求后端接口

攜帶code調用后端接口
這里使用封裝好的axios和user接口api，直接使用即可
utils/request.js,這個js主要封裝了axios，對請求統一管理，請求url以及數據拼接以及響應處理（這個工具類需要和后端的返回對象JsonData.java對上，下面會貼出來代碼）。

const BASE_URL = 'http://api.ant-qywx.com:9900'; function request({ url, data, method }) {return new Promise((resolve, reject) => {// 發起網絡請求uni.request({url: BASE_URL + url,data,method,success: ({ data }) => {console.log("data",data)// 響應成功，獲取數據，解析數據if (data.success) {resolve(data);} else {// 響應失敗，給用戶提示uni.showToast({title: data.message,icon: 'none',mask: true,duration: 3000,});reject(data.message);}},fail: (error) => {reject(error);},complete: () => {// 關閉加載uni.hideLoading();},});}); }export default request;

引入api

<script>// 引用用戶接口api 調用后端登錄接口import {loginAuth} from '../../api/user.js'; </script>

編寫登錄方法調用企業微信登錄接口

methods: { // 企業微信下程序登錄的方法login() {wx.qy.login({success: function(res) {console.log("res", res)loginAuth(res).then((response) => {console.log("response", response)});}})} }

api/user.js這里js，作用是管理用戶相關接口api

import request from '../utils/request';/*** 微信用戶授權登錄，攜帶appid和code參數，調用后端接口獲取Openid*/ export function loginAuth(data) {return request({url: '/mini/login',data: {code: data.code,},}); }

2.3. 項目源碼

https://gitee.com/gblfy/qywx-inner-java-api

三、后端部分

3.1. yml配置

application.yml

server:port: 9900qywx:mini:agentSecret: i5t-rh8bXeNCgihcYPrG9ZPpWkivzPJ69sv570osk6IcorpId: ww17f8d10783494584

3.2. 獲取用戶信息接口

Controller

package com.gblfy.qywxin.controller;import com.gblfy.qywxin.service.QywxInnerMiniService; import com.gblfy.qywxin.utils.JWTUtils; import com.gblfy.qywxin.vo.JsonData; import com.gblfy.qywxin.vo.QywxInnerUser; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController;import java.util.Map;@RestController @RequestMapping("/mini") public class QywxMiniController {private static final Logger logger = LoggerFactory.getLogger(QywxMiniController.class);@Value("${qywx.mini.corpId}")private String corpId;@Autowiredprivate QywxInnerMiniService qywxInnerMiniService;@GetMapping("/login")public JsonData login(@RequestParam(value = "code", required = false) String code) {logger.info("accept code->{}", code);Map result = qywxInnerMiniService.getOauthUser(corpId, code);logger.info("accept result->{}", result);//本案例僅從企業微信接口獲取未從數據表中獲取QywxInnerUser user = new QywxInnerUser();user.setCorpId(corpId);user.setUserId((String) result.get("userId"));String token = JWTUtils.geneJsonWebToken(user);result.put("token", token);return JsonData.buildSuccess(result);} }

3.3. 獲取token

service

package com.gblfy.qywxin.service;import com.gblfy.qywxin.config.QywxInnerConfig; import com.gblfy.qywxin.utils.RestUtils; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Service;import java.util.Map;@Service public class QywxInnerMiniService {private static final Logger logger = LoggerFactory.getLogger(QywxInnerMiniService.class);@Value("${qywx.mini.agentSecret}")private String AGENT_SECRET;public Map getOauthUser(String corpId, String code) {// 1.通過corpId獲取AccessTokenString accessToken = getAccessToken(corpId);String getOauthUrl = String.format(QywxInnerConfig.MINI_OAUTH_USER_URL, accessToken, code);Map response = RestUtils.get(getOauthUrl);if (response.containsKey("errcode") && (Integer) response.get("errcode") != 0) {logger.error(response.toString());return response;}System.out.println("response->" + response);// 目前已經獲取到userid了// return response;//根據用戶UserId->獲取通訊錄用戶詳情getString userId = (String) response.get("userid");String url = String.format(QywxInnerConfig.USER_DETAIL_URL, accessToken, userId);Map detaiResponse = RestUtils.get(url);//獲取錯誤日志if (detaiResponse.containsKey("errcode") && (Integer) detaiResponse.get("errcode") != 0) {logger.error(detaiResponse.toString());}return detaiResponse;}/*** 通過corpId獲取AccessToken** @param corpId 企業ID* @return*/public String getAccessToken(String corpId) {String result = "";String accessTokenUrl = String.format(QywxInnerConfig.MINI_ACCESS_TOKEN_URL, corpId, AGENT_SECRET);Map response = RestUtils.get(accessTokenUrl);//獲取錯誤日志if (response.containsKey("errcode") && (Integer) response.get("errcode") != 0) {logger.error(response.toString());} else {result = (String) response.get("access_token");}return result;} }

3.4. 工具類

3.5. vo對象

package com.gblfy.qywxin.vo;/*** 返回封裝對象** @author gblfy* @date 2022-01-12*/ public class JsonData {/*** 業務上的成功或失敗*/private boolean success = true;private Integer code;private String msg;private Object data;public JsonData() {}public JsonData(Integer code, Object data, String msg,boolean success) {this.code = code;this.data = data;this.msg = msg;this.success = success;}public static JsonData buildSuccess() {return new JsonData(0, null, null,true);}public static JsonData buildSuccess(Object data) {return new JsonData(0, data, null,true);}public static JsonData buildError(String msg) {return new JsonData(-1, null, msg,false);}public static JsonData buildError(Integer code, String msg) {return new JsonData(code, null, msg,false);}public Integer getCode() {return code;}public void setCode(Integer code) {this.code = code;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public Object getData() {return data;}public void setData(Object data) {this.data = data;}public boolean getSuccess() {return success;}public void setSuccess(boolean success) {this.success = success;} }
