⭐前言
大家好,我是yma16,本文分享OAuth规则机制下实现个人站点接入qq三方登录。
oauth授权
OAuth是一种授权机制,用于允许用户(资源所有者)向第三方应用程序授予有限的访问权限,而不必将凭证直接提供给第三方应用程序。OAuth的目的是为了保护用户的私密数据,如社交媒体帐户、云存储、银行帐户等。它通过一个流程,将用户授权给第三方应用程序访问用户的资源,而不需要第三方应用程序获得用户的凭证信息。这样做可以减少用户数据泄露的风险。OAuth是一个开放的标准,由OAuth工作组维护,并得到许多组织的支持和使用。
oauth的发展
OAuth协议的发展历史可以追溯到2004年,当时美国国防部提出了一个名为“OpenID Connect”的开放式身份认证和授权标准,旨在解决Web 2.0中的身份认证和授权问题。OAuth1.0于2005年被RFC 5849正式标准化,OAuth2.0于2011年被RFC 6749正式标准化 。
OAuth1.0的主要特点是将用户的认证信息(如用户名和密码)与第三方应用的请求分离开来,从而提高了安全性。
OAuth2.0则在OAuth1.0基础上进一步改进,增加了更多的功能和灵活性,如授权码模式、隐式模式、密码模式等 。
效果
在个人站点实现三方qq登录
链接直达:https://yongma16.xyz
唤起三方登录url
获取qq用户账号头像和openid登入
⭐qq三方登录流程
前提条件: 存在可访问的网站,在qq互联中心创建应用审核
友情提示:网站不可使用外部cdn,可导致审核人员查看白屏而失败
💖qq互联中心创建网页应用
填写域名资料,提交审核
💖配置回调地址redirect_uri
回调地址是用户使用qq登录之后调整的地址会携带code和state的参数
💖流程分析
- 唤起qq授权登录url
- 登录qq成功获取code
- 通过code去换取access_token
- 通过access_token去换取openid
- 通过access_token和openid去换取userinfo
⭐思路分解
1.登录页面新开窗口的auth授权qq页面
2.自定义node服务去渲染回调redirect_uri,成功登录时回传url上的参数给父页面,然后用定时器关闭页面
3. 拿到code后去换取token
4. 拿到token去换取openid
5. 拿到openid去换取userinfo
6. 使用openid去注册网站用户,显示nickname网名
⭐技术选型+实现
💖技术选型:
后端:
node
前端:
vue2
后端node封装接口
💖实现
node封装接口:
api.js

const appid=自己的appid

resolve(response)
} else {
reject(error)
}
})
}
)
}
module.exports={
getAuthUrl,

node开放接口:
const hostname = 'localhost';
const port = 6677;
const express = require("express");
const {getAuthUrl,getToken,getOpenId,getUserInfo}=require('./service/api.js');
const app = express();
app.listen(port,hostname, () => {

});
// server your css as static
app.use(express.static(__dirname));
// views
const thirdLoginDir='/views/thirdLogin/';
app.get("/getAuthUrl",async (req, res) => {
try{
const {query}=req
const {state}=query
const url=await getAuthUrl(state)
res.json({

}
catch (e) {

console.log('code',code)

const urlLength=urlArray.length
if(urlLength>1){
urlArray[urlLength-1].split('&').forEach(item=>{

const key=itemArray[0]
const value=itemArray[1]
data[key]=value
})

if(window.opener)

vue前端qq登录的调用:
async qqLogin () {
try {
const that = this
// qq
const res = await that.$axios
.post('/third-login/getAuthUrl')
console.log('res', res)
if (res.data && res.data.data) {
const resData = res.data.data
console.log('resData', resData)
if (resData ) {
let url = resData
console.log('url', url)
const openHandle = window.open(url, 'width:800px;height:700px', '_black')
console.log('openHandle', openHandle)
window.onmessage = async (res) => {
const {origin, data} = res
if (origin.includes('yongma16.xyz')) {
const {code, state} = data
console.log('code state', code, state)
that.thirdLoginConfig.qCode = code
that.thirdLoginConfig.qState = state
const tokenRes = await that.getAccessToken(code)
console.log('tokenRes', tokenRes)
}
}
}
}
return new Promise(resolve => {
resolve(true)
})
} catch (e) {
return new Promise((resolve, reject) => {
reject(e)
})
}
},
async getAccessToken (code) {
try {
const tokenUrl = '/third-login/getToken'
const params = {
code
}
const tokenRes = await this.$axios.get(tokenUrl, {params})
console.log('tokenRes', tokenRes)
if (tokenRes) {
const {access_token, expires_in, refresh_token} = tokenRes.data.data
if (access_token) {
this.thirdLoginConfig.qToken = access_token
await this.getOpenId(access_token)
}
}
} catch (e) {
console.log('token error', e)
}
},
async getOpenId (token) {
try {
const tokenUrl = '/third-login/getOpenId'
const params = {
access_token: token
}
const openIdRes = await this.$axios.get(tokenUrl, {params})
console.log('openIdRes', openIdRes)
if (openIdRes) {
const {openid} = openIdRes.data.data
if (openid) {
this.thirdLoginConfig.qOpenid = openid
await this.getQUserinfo(this.thirdLoginConfig.qToken, openid)
}
}
} catch (e) {
console.log('token error', e)
}
},
async getQUserinfo (token, openId) {
try {
