建网站要定制还是第三方系统专业从事网站开发公司

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
1.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.如果你想本地调试，回调到你的线上地址。你可以在本地设置本地域名，做反向代理。我是用的是phpstudy，方向代理自己的线上域名。

如果你还是不明白，可以留言

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

1. 前端点击qq图标登录代码:

<div @click="handleToLogin('qq')">gitee
</div>const handleToLogin = (type:string)=>{window.location.href="http://localhost:3000/user/oauth/qq"
}

2. http://localhost:3000/user/oauth/qq后端接口代码

	@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}`;}

3. 回调地址前端代码

<template><div class="u-f u-f-ac u-f-ajc" style="width: 100%;height:100vh"><template v-if="isOauth"><el-resulticon="success"title="授权成功,跳转中..."></el-result></template><template v-else><el-resulticon="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>

4. requestQQLogin请求的后端代码

// 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"
};

	//qq登录@Post('/oauth/qqLogin')async getQQInfo(@Body() qqLoginDto:QqLoginDto,@IpAddress() clientIp: string) {let {code,operationSystem,browser} = giteeLoginDtolet accessToken:any = await this.handleGetQQAccessToken(code)if(!accessToken.data){return this.msgService.fail("code过期，请重新登录")}let giteeInfo:any = await this.getQQInfoByAccessToken(accessToken.data.accessToken,accessToken.data.appId);if(!giteeInfo.data){return this.msgService.fail("获取qq账号信息失败")}let { nickname } = giteeInfo.data.userData;let clientId = 0;let qqId = sysConfigEnum.qqLoginConfig + JSON.parse(JSON.stringify(giteeInfo.data.openid));//判断qq是否有关联账号。如果有就登陆，没有就新创建一个账号let userNum = await this.userEntity.createQueryBuilder().where({ qqId:qqId }).getCount()let username;//没有账号，注册帐号if(userNum<=0){let roleData = await this.roleEntity.createQueryBuilder().where({roleName:"试用角色"}).getOne()username = handleGetCode(8);username = await this.handleGetUsername(username);let originalPwd = handleGetCode(8);let password = JSON.parse(JSON.stringify(originalPwd))password = securityMd5(password)let userData;try {userData = await this.userEntity.createQueryBuilder().insert().values({username,originalPwd,password,qqId:qqId,roleId:roleData.id}).execute();}catch (error) {throw new HttpException(error,HttpStatus.SERVICE_UNAVAILABLE)}clientId = userData.identifiers[0]["id"]}else{let userData = await this.userEntity.createQueryBuilder().where({qqId:qqId}).getOne()username = userData.usernameclientId = userData.id;}let ip  = handleDealIpv6ToIpv4(clientIp)let token = this.authService.createToken({id:clientId,username,ip})await this.updateUserInfoStatus(clientId,token,ip,operationSystem,browser)return {id:clientId,username,token}}//获取gitee的accessTokenasync handleGetQQAccessToken(code:string):Promise<resInterface>{let key = sysConfigEnum.qqLoginConfiglet data = await this.sysConfigService.handleGetSysData(key)if(!data.appId || !data.appKey || !data.redirectUrl){return {data:false,msg:""};}let appId = data.appId;let appKey = data.appKey;let redirectUrl = data.redirectUrl;//回调路劲获取codelet authData = await axios.get(qqOauthConfig.getAccessTokenUrl+`&code=${code}&client_id=${appId}&client_secret=${appKey}&redirect_uri=${redirectUrl}`).then(res=>{let resArr = res.data.split("&")let accessToken = resArr[0].split("=")[1]let expiresIn = resArr[1].split("=")[1]let refreshToken = resArr[2].split("=")[1]return {accessToken,expiresIn,refreshToken};}).catch(err=>{return err.data})if(authData?.error){return this.msgService.commonRes(false,authData?.error?.error_description);}else{return this.msgService.commonRes({accessToken:authData?.accessToken,appId},"");}}//通过access_token获取gitee信息async getQQInfoByAccessToken(accessToken: boolean | string,appId:string){let authData = await axios.get(qqOauthConfig.openId+`?access_token=${accessToken}`).then(res=>{let data = JSON.parse(res.data.substring(9, res.data.length-3))let clientId = data.client_id;let openid = data.openid;return {clientId,openid};}).catch(err=>{return err.data})if(authData?.error){return this.msgService.commonRes(false,authData?.error?.error_description);}let userData = await axios.get(qqOauthConfig.qqUserAPI+`?access_token=${accessToken}&oauth_consumer_key=${appId}&openid=${authData.openid}`).then(res=>{return res.data;}).catch(err=>{return err.data})if(userData?.error){return this.msgService.commonRes(false,authData?.error?.error_description);}else{return this.msgService.commonRes({userData,openid:authData.openid},"");}}

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
