项目场景:
前端使用vue3+ts 后端使用nestjs
1.申请appId,appKey
1.进入qq互联官网。创建应用
特别注意
在填写网站回调域时,需要你线上真实能访问的。不然审核不通过。我的回调地址是前端路由地址
2.代码演示
特别注意:
如果你跟我一样是前后端分离的模式开发的,应用回调地址填写的应该是你的前端路由地址。在你的前端页面获取code,把code值传给后端接口。后端接口通过code获取gitee用户信息。
代码演示
我的应用回调地址:http://localhost:8080/vuecms/qq
- 前端点击qq图标登录代码:
javascript
<div @click="handleToLogin('qq')">
gitee
</div>
const handleToLogin = (type:string)=>{
window.location.href="http://localhost:3000/user/oauth/qq"
}
javascript
@Get('/oauth/qq')
async qqLogin(@Res() response: Response) {
let appId = 你的appId;
let redirectUrl = 你的回调地址;
const state = Date.now()
let scope = "get_user_info,list_album"
return qqOauthConfig.authorizeUrl+`&client_id=${appId}&redirect_uri=${redirectUrl}&state=${state}&scope=${scope}`;
}
- 回调地址前端代码
javascript
<template>
<div class="u-f u-f-ac u-f-ajc" style="width: 100%;height:100vh">
<template v-if="isOauth">
<el-result
icon="success"
title="授权成功,跳转中..."
>
</el-result>
</template>
<template v-else>
<el-result
icon="error"
title="授权失败"
>
</el-result>
</template>
</div>
</template>
<script setup lang="ts">
import {useRoute,useRouter} from "vue-router";
import {onMounted} from "@vue/runtime-core";
import {requestGiteeLogin} from "@/network/common/oauthPage";
import {setToken, setUserId, setUsername} from "@/utils/storage";
import {handleGetCurInstance} from "@/utils/utils";
import {ref} from "vue"
let route = useRoute()
let router = useRouter()
let query = route.query;
let {model} = handleGetCurInstance()
let isOauth = ref(true)
onMounted(()=>{
//获取返回的code,通过code对后端发起请求,获取qq用户信息
let {code,state} = query;
let form = {
code,state
}
requestQQLogin(form).then(res=>{
let {data,code,message} = res;
if(code==200){
setToken(data.token)
setUserId(data.id)
setUsername(data.username)
window.location.href="/"
}else{
model.handleMsg(message,"warning")
isOauth.value =false;
}
})
})
</script>
- requestQQLogin请求的后端代码
javascript
// qq 的认证配置
export const qqOauthConfig = {
cid: "",//gitee官网设置获取
secret: "",
redirectURL: '',//gitee官网配置进行填写
authorizeUrl: 'https://graph.qq.com/oauth2.0/authorize?response_type=code',
getAccessTokenUrl: 'https://graph.qq.com/oauth2.0/token?grant_type=authorization_code',
openId:"https://graph.qq.com/oauth2.0/me",
qqUserAPI:"https://graph.qq.com/user/get_user_info"
};
javascript
//qq登录
@Post('/oauth/qqLogin')
async getQQInfo(@Body() qqLoginDto:QqLoginDto,@IpAddress() clientIp: string) {
let {code,operationSystem,browser} = giteeLoginDto
let accessToken:any = await this.handleGetQQAccessToken(code)

3.特别注意
如果以上步骤都没问题。需要把本地测试回调地址改为线上路径
