0:以gitee为例,首先开通gitee第三方登录:(在设置里面的第三方应用里面新建)
0.1:后端引入JustAuth第三方登陆框架:
<dependency>
<groupId>me.zhyd.oauth</groupId>
<artifactId>JustAuth</artifactId>
<version>1.15.9</version>
</dependency>
1:在登陆前端加上按钮并且填写登录逻辑
giteeLogin() {
PreLoginByGitee().then(res => {
Cookies.set("user-uuid", res.uuid)
window.location = res.authorizeUrl
})
},
}
export function PreLoginByGitee() {
return request({
url: '/PreLoginByGitee',
headers: {
isToken: false
},
method: 'get',
})
}
2:后端的PreLoginByGitee接口:任务就是生成url,跳到认证url上面
@GetMapping("/PreLoginByGitee")
public AjaxResult PreLoginByGitee() {
AjaxResult ajax = AjaxResult.success();
AuthRequest authRequest = new AuthGiteeRequest(AuthConfig.builder()
.clientId("***********************************")
.clientSecret("************************************")
.redirectUri("http://localhost/callback")
.build());
String uuid = IdUtils.fastUUID();
String authorizeUrl = authRequest.authorize(uuid);
ajax.put("authorizeUrl", authorizeUrl);
ajax.put("uuid", uuid);
return ajax;
}
3:再跳到gitee认证地址后授权,成功则会跳到回调地址,失败则一直转圈圈:
回调地址:
loginByGitee组件:mounted钩子函数会在加载开始的时候:在这里面调用LoginByGitee方法:
<template>
<div v-loading="loading" style="height: 100%;width: 100%;">
正在加载中...
div>
template>
<script>
import Cookies from "js-cookie";
export default {
name: "loginByGitee",
data() {
return {
loading: true
}
},
mounted() {
this.loading = true;
console.log("uuid", Cookies.get("user-uuid"))
const formBody = {
uuid: Cookies.get("user-uuid"),
code: this.$route.query.code
}
this.$store.dispatch("LoginByGitee", formBody).then(() => {
this.$router.push({path: this.redirect || "/"}).catch(() => {
});
}).catch(() => {
this.loading = false;
});
}
}
script>
<style scoped>
style>
4:LoginByGitee方法:这方法里面会调用loginByGitee方法
LoginByGitee({commit}, body) {
return new Promise((resolve, reject) => {
loginByGitee(body.code, body.uuid).then(res => {
setToken(res.token)
commit('SET_TOKEN', res.token)
resolve()
}).catch(error => {
reject(error)
})
})
},
5:loginByGitee方法:该方法到后端找loginByGitee接口,并带上code和uuid
export function loginByGitee(code, uuid) {
const data = {
code,
source: "Gitee",
uuid
}
return request({
url: '/loginByGitee',
headers: {
isToken: false
},
method: 'post',
data: data
})
}
6:后端接口接收–loginByGitee:然后进入service层的loginByOtherSource方法
@Autowired
private SysLoginService loginService;
@PostMapping("/loginByGitee")
public AjaxResult loginByGitee(@RequestBody LoginByOtherSourceBody loginByOtherSourceBody) {
AjaxResult ajax = AjaxResult.success();
String token = loginService
.loginByOtherSource(loginByOtherSourceBody.getCode(), loginByOtherSourceBody.getSource(), loginByOtherSourceBody.getUuid());
ajax.put(Constants.TOKEN, token);
return ajax;
}
}
7:后端loginByOtherSource方法:
@Autowired
private SysPermissionService permissionService;
public String loginByOtherSource(String code, String source, String uuid) {
AuthRequest authRequest = new AuthGiteeRequest(AuthConfig.builder()
.clientId("***********************************")
.clientSecret("**************************************************")
.redirectUri("http://localhost/callback")
.build());
AuthResponse<AuthUser> login = authRequest.login(AuthCallback.builder().state(uuid).code(code).build());
System.out.println(login);
AuthUser authUser = login.getData();
SysUser sysUser = new SysUser();
sysUser.setUserName(authUser.getUsername());
sysUser.setSource(authUser.getSource());
List<SysUser> sysUsers = userService.selectUserListNoDataScope(sysUser);
if (sysUsers.size() > 1) {
throw new ServiceException("第三方登录异常,账号重叠");
} else if (sysUsers.size() == 0) {
sysUser.setNickName(authUser.getNickname());
sysUser.setAvatar(authUser.getAvatar());
sysUser.setEmail(authUser.getEmail());
sysUser.setRemark(authUser.getRemark());
userService.registerUserAndGetUserId(sysUser);
AsyncManager.me().execute(AsyncFactory.recordLogininfor(sysUser.getUserName(), Constants.REGISTER,
MessageUtils.message("user.register.success")));
} else {
sysUser = sysUsers.get(0);
}
AsyncManager.me().execute(AsyncFactory.recordLogininfor(sysUser.getUserName(), Constants.LOGIN_SUCCESS, MessageUtils.message("user.login.success")));
LoginUser loginUser =
new LoginUser(sysUser.getUserId(), sysUser.getDeptId(), sysUser, permissionService.getMenuPermission(sysUser));
recordLoginInfo(loginUser.getUserId());
return tokenService.createToken(loginUser);
}
7.1:首先是 AuthResponse login = authRequest.login(AuthCallback.builder().state(uuid).code(code).build());
这里用拿到的uuid和code登录,成功就可以拿到gitee这个第三方应用的信息
7.2:get到第三方的各种数据来登录我们的系统,用用户名和source先查看这个第三方用户在不在我们的数据库中
