node第三方登陆github（express）

1.新建授权app(OAuth—Apps)

创建成功以后&＃xff1a;Client ID&＃xff08;key&＃xff09;和 Client Secret(密钥)是需要用到的

2.使用的node框架&＃xff1a;express

下载node-fetch

yarn add node-fetch

或

npm i node-fetch -s

新建login路由&＃xff1a;

scope:授权服务

state&＃xff1a;回调参数,

router.get("/login", function (req, resp) {let path &＃61; "https://github.com/login/oauth/authorize";path &＃43;&＃61; &＃39;?client_id&＃61;&＃39;;path &＃43;&＃61; &＃39;&state&＃61;state&＃39;;path &＃43;&＃61; &＃39;&scope&＃61;user:email&＃39;;resp.redirect(path);
})

直接跳转到github第三方登陆页面&＃xff0c;授权成功会回调在OAuth Apps设置的回调url

新建github路由

router.get("/github", function (req, resp) {let path &＃61; &＃39;https://github.com/login/oauth/access_token&＃39;;const params &＃61; {client_id: &＃39;&＃39;,client_secret: &＃39;&＃39;,code: req.query.code}fetch(path, {method: &＃39;POST&＃39;,headers: {&＃39;Content-Type&＃39;: &＃39;application/json&＃39;},body: JSON.stringify(params)}).then(function (res) {return res.text();}).then(function (body) {const args &＃61; body.split(&＃39;&&＃39;);let arg &＃61; args[0].split(&＃39;&＃61;&＃39;);const access_token &＃61; arg[1];console.log(body);console.log(access_token);return access_token;}).then(async (token) &＃61;> {const url &＃61; &＃39; https://api.github.com/user?access_token&＃61;&＃39; &＃43; token;await fetch(url).then(res &＃61;> {return res.json();}).then(res &＃61;> {console.log(res);resp.send(res);})})
})
