Spring boot 项目（十三）——实现微信公众号授权登录获取用户信息

时间：2020-03-03 12:30:18

引言

微信公众号开发中，必不可少的一环：公众号授权登录、获取微信用户信息

前期准备

内网渗透=>生成本地指定端口映射的外网域名

链接：内网渗透工具natapp使用详解

域名生成之后修改yml文件配置

申请并配置微信测试公众号

01、链接：点击申请微信测试公众号，并扫码关注测试公众号

02、备份appID和appsecret，后面需要用

03、接口配置信息修改（注：此处会回调后台签名验证方法，配置时需启动后台）

04、配置网页授权域名，用于获取微信用户信息

下载微信开发者程序进行测试

代码部分

01、maven依赖

<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.54</version></dependency><dependency><groupId>com.github.binarywang</groupId><artifactId>weixin-java-mp</artifactId><version>4.1.0</version></dependency><dependency><groupId>com.github.binarywang</groupId><artifactId>weixin-java-common</artifactId><version>4.1.0</version></dependency>

02、html

<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1" /><title>微信授权登录示例</title><script src="/jquery/1.10.2/jquery.min.js"></script></head><body style="text-align: center;"><h2>欢迎您：[[${session.userInfo?.nickname}]]!</h2><hr/><span>用户信息：[[${session.userInfo}]]</span><script th:inline="javascript">var sceneStr;var t;var userInfo = [[${session.userInfo}]];var appId = [[${wxConfig.appId}]];var openId = [[${session.openId}]];var redirectUri = [[${redirectUri}]];console.log("======用户信息开始=========");console.log(userInfo);if(userInfo != null){alert("您好："+userInfo.nickname);}console.log("======用户信息结束=========");$(function () {if (openId == null) {window.location.href = 'https://open./connect/oauth2/authorize?appid='+appId +'&redirect_uri='+redirectUri +'&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect';}})</script></body></html>

03、yml配置

spring:thymeleaf:cache: false #关闭缓存wx:appId: wxbd9c69753d14236eappSecret: b44d04f1361136cdef17c07f642641a7server:

04、controller层

@Autowiredprivate WxConfig wxConfig;@RequestMappingpublic String index(Model model) throws UnsupportedEncodingException {model.addAttribute("wxConfig",wxConfig);// 进行编码model.addAttribute("redirectUri", URLEncoder.encode(wxConfig.getServer()+"/webAuthLogin/getCode","UTF-8"));return "login";}//获取openid和access_token的连接private static String getOpenId = "https://api./sns/oauth2/access_token?appid=APPID&secret=APPSECRET&code=CODE&grant_type=authorization_code";//获取用户基本信息的连接private static String getUserInfo = "https://api./sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID&lang=zh_CN";@Autowiredprivate HttpSession httpSession;/*** 微信网页授权回调* @param code* @return*/@RequestMapping("getCode")public String getCode(String code){String getOpenIdUrl = getOpenId.replace("APPID", wxConfig.getAppId()).replace("APPSECRET", wxConfig.getAppSecret()).replace("CODE", code);String response = HttpClientUtil.doGet(getOpenIdUrl);JSONObject jsonObject = JSONObject.parseObject(response);String accessToken = jsonObject.get("access_token") == null ? null :jsonObject.get("access_token").toString();String openId = jsonObject.get("openid") == null ? null : jsonObject.get("openid").toString();httpSession.setAttribute("accessToken",accessToken);httpSession.setAttribute("openId",openId);httpSession.setAttribute("userInfo",getUserInfo(openId,accessToken));return "redirect:/";}/*** 获取微信用户信息* @param openId* @param accessToken* @return*/private JSONObject getUserInfo(String openId,String accessToken){String userInfoUrl = getUserInfo.replace("ACCESS_TOKEN",accessToken).replace("OPENID", openId);String userInfo = HttpClientUtil.doGet(userInfoUrl);JSONObject jsonObject = JSONObject.parseObject(userInfo);return jsonObject;}

05、其他部分

由于篇幅有限，我就不放上去了。文章末尾会奉上源码作为参考。
