SpringBoot整合微信登錄功能的實現方案
更新時間：2021年10月28日 10:38:46 作者：小玩偶啊
今天通過本文給大家分享微信登錄與SpringBoot整合過程,微信掃描登錄實現代碼知道掃描后點擊登錄的全部過程，本文給大家介紹的非常詳細，需要的朋友可以參考下
1. OAuth2解決什么問題？
OAuth2：是針對特定問題一種解決方案
可以解決兩個問題：
a. 開放系統(tǒng)間授權
b. 分布式訪問問題
解決方案：
a. 方式一：用戶名密碼復制
b. 通用開發(fā)者key
c. 辦法令牌
2. 微信掃描登錄
2.1 添加必要的依賴
<!--httpclient-->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
</dependency>
<!--commons-io-->
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
</dependency>
<!--gson-->
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
</dependency>
</dependencies>
2.2 application.properties 添加配置
下面的配置是你申請的有關的，重定向鏈接是登陸成功需要跳轉的請求
# 微信開放平臺 appid wx.open.app_id=wxed94c01bb89b47 # 微信開放平臺 appsecret wx.open.app_secret=a7482517235173ddb43788de60b90e # 微信開放平臺 重定向url wx.open.redirect_url=http://localhost:8160/api/ucenter/wx/callback
2.3 登錄請求
//1 生成微信掃描二維碼
@GetMapping("login")
public String getWxCode() {
System.out.println("調用了兄弟。。。。。。。。。。。。。。。。。。。。。。。。。。。。。");
//固定地址，后面拼接參數
// String url = "https://open.weixin.qq.com/" +
// "connect/qrconnect?appid="+ ConstantWxUtils.WX_OPEN_APP_ID+"&response_type=code";
// 微信開放平臺授權baseUrl %s相當于?代表占位符
String baseUrl = "https://open.weixin.qq.com/connect/qrconnect" +
"?appid=%s" +
"&redirect_uri=%s" +
"&response_type=code" +
"&scope=snsapi_login" +
"&state=%s" +
"#wechat_redirect";
//對redirect_url進行URLEncoder編碼
String redirectUrl = ConstantWxUtils.WX_OPEN_REDIRECT_URL;
try {
redirectUrl = URLEncoder.encode(redirectUrl, "utf-8");
}catch(Exception e) {
}
//設置%s里面值
String url = String.format(
baseUrl,
ConstantWxUtils.WX_OPEN_APP_ID,
redirectUrl,
"atguigu"
);
//重定向到請求微信地址里面
return "redirect:"+url;
}
請求成功后，掃描二維碼點擊缺點登錄
會自動調用callback
//2 獲取掃描人信息，添加數據
@GetMapping("callback")
public String callback(String code, String state) {
try {
//1 獲取code值，臨時票據，類似于驗證碼
//2 拿著code請求 微信固定的地址，得到兩個值 accsess_token 和 openid
String baseAccessTokenUrl = "https://api.weixin.qq.com/sns/oauth2/access_token" +
"?appid=%s" +
"&secret=%s" +
"&code=%s" +
"&grant_type=authorization_code";
//拼接三個參數 ：id 秘鑰 和 code值
String accessTokenUrl = String.format(
baseAccessTokenUrl,
ConstantWxUtils.WX_OPEN_APP_ID,
ConstantWxUtils.WX_OPEN_APP_SECRET,
code
);
//請求這個拼接好的地址，得到返回兩個值 accsess_token 和 openid
//使用httpclient發(fā)送請求，得到返回結果
String accessTokenInfo = HttpClientUtils.get(accessTokenUrl);
//從accessTokenInfo字符串獲取出來兩個值 accsess_token 和 openid
//把accessTokenInfo字符串轉換map集合，根據map里面key獲取對應值
//使用json轉換工具 Gson
Gson gson = new Gson();
HashMap mapAccessToken = gson.fromJson(accessTokenInfo, HashMap.class);
String access_token = (String)mapAccessToken.get("access_token");
String openid = (String)mapAccessToken.get("openid");
//把掃描人信息添加數據庫里面
//判斷數據表里面是否存在相同微信信息，根據openid判斷
UcenterMember member = memberService.getOpenIdMember(openid);
if(member == null) {//memeber是空，表沒有相同微信數據，進行添加
//3 拿著得到accsess_token 和 openid，再去請求微信提供固定的地址，獲取到掃描人信息
//訪問微信的資源服務器，獲取用戶信息
String baseUserInfoUrl = "https://api.weixin.qq.com/sns/userinfo" +
"?access_token=%s" +
"&openid=%s";
//拼接兩個參數
String userInfoUrl = String.format(
baseUserInfoUrl,
access_token,
openid
);
//發(fā)送請求
String userInfo = HttpClientUtils.get(userInfoUrl);
System.out.println("userInfo::::"+userInfo);
//獲取返回userinfo字符串掃描人信息
HashMap userInfoMap = gson.fromJson(userInfo, HashMap.class);
String nickname = (String)userInfoMap.get("nickname");//昵稱
String headimgurl = (String)userInfoMap.get("headimgurl");//頭像
member = new UcenterMember();
member.setOpenid(openid);
member.setNickname(nickname);
member.setAvatar(headimgurl);
memberService.save(member);
}
//使用jwt根據member對象生成token字符串
String jwtToken = JwtUtils.getJwtToken(member.getId(), member.getNickname());
//最后：返回首頁面，通過路徑傳遞token字符串
return "redirect:http://localhost:3000?token="+jwtToken;
}catch(Exception e) {
throw new GuliException(20001,"登錄失敗");
}
}
查找用戶信息根據token
//根據token獲取用戶的信息
@GetMapping("getmemberInfo")
public R getmemberInfo(HttpServletRequest request){
//調用jwt工具類，根據request對象獲取頭部信息
//獲的用戶的id
String memberId = JwtUtils.getMemberIdByJwtToken(request);
UcenterMember ucenterMember = memberService.getById(memberId);
return R.ok().data("userInfo",ucenterMember);
}
ConstantWxUtils 獲取配置文件的值
@Component
public class ConstantWxUtils implements InitializingBean {
@Value("${wx.open.app_id}")
private String appId;
@Value("${wx.open.app_secret}")
private String appSecret;
@Value("${wx.open.redirect_url}")
private String redirectUrl;

public static String WX_OPEN_APP_SECRET;
public static String WX_OPEN_REDIRECT_URL;

}
}

2.4 前端
點擊微信登錄 發(fā)送請求
<div class="more-sign">
<h6>社交帳號登錄</h6>
<ul>
<li><a id="weixin" class="weixin" target="_blank" rel="external nofollow" ><i class="iconfont icon-weixin"/></a></li>
<li><a id="qq" class="qq" target="_blank" href="#" rel="external nofollow" ><i class="iconfont icon-qq"/></a></li>
</ul>
</div>
到二維碼的界面
掃描后 點擊登錄
將后端傳遞的token值中的用戶信息交給前端
created() {
//獲取路徑里面token值?后面的值
this.token = this.$route.query.token
console.log(this.token)
if(this.token) {//判斷路徑是否有token值
this.wxLogin()
}
},
//微信登錄顯示的方法
wxLogin() {
//console.log('************'+this.token)
//把token值放到cookie里面
cookie.set('guli_token',this.token,{domain: 'localhost'})
cookie.set('guli_ucenter','',{domain: 'localhost'})
//console.log('====='+cookie.get('guli_token'))
//調用接口，根據token值獲取用戶信息
loginApi.getLoginUserInfo()
.then(response => {
this.loginInfo = response.data.data.userInfo
cookie.set('guli_ucenter',this.loginInfo,{domain: 'localhost'})
})
},
