各位大佬请教一个问题，我这里没有获得unionid的原因是小程序没有认证完成吗？ // app.js App({ onLaunch() { // 展示本地存储能力 const logs = wx.getStorageSync('logs') || [] logs.unshift(Date.now()) wx.setStorageSync('logs', logs) // 登录 wx.login({ success: res => { // 发送 res.code 到后台换取 openId, sessionKey, unionId if (res.code) { // 发送 res.code 到后台换取 openId, sessionKey, unionId wx.request({ url: 'http://localhost:8081/api/login', data: { code: res.code }, success: function (response) { // 处理登录结果 console.log(response.data); } }) } else { console.log('登录失败！' + res.errMsg) } } }) }, globalData: { userInfo: null } }) package com.msbd.backend.test; import cn.dev33.satoken.stp.StpUtil; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.URL; import com.alibaba.fastjson.JSONObject; @RestController public class LoginController { private static final String APPID = "xxxxxxxxxxxxxxx"; @GetMapping("/api/login") public String login(@RequestParam("code") String code) { try { // 假设这里使用 saToken 生成 JWT 令牌 String jwtToken = StpUtil.getTokenInfo().getTokenValue(); String url = "https://api.weixin.qq.com/sns/jscode2session?appid=" + APPID + "&secret=" + jwtToken + "&js_code=" + code + "&grant_type=authorization_code"; URL obj = new URL(url); HttpURLConnection con = (HttpURLConnection) obj.openConnection(); con.setRequestMethod("GET"); BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream())); String inputLine; StringBuffer response = new StringBuffer(); while ((inputLine = in.readLine()) != null) { response.append(inputLine); } in.close(); JSONObject jsonObject = JSONObject.parseObject(response.toString()); String unionid = jsonObject.getString("unionid"); System.out.println("========================>unionid = " + unionid); // 根据 unionid 查找或创建用户 // ... return "Login success with unionid: " + unionid; } catch (Exception e) { e.printStackTrace(); return "Login failed"; } } } [图片][图片]
