登录GitHub申请AuthApp:
Settings/Developer/settings/AuthApp
constconfig={client_id:"",client_secret:"",};第一步:前端触发服务器接口由服务器重定向到Github授权页面
router.get("/github/login",async(ctx)=>{constpath=`https://github.com/login/oauth/authorize?client_id=${config.client_id}`;ctx.redirect(path);});第二步:GitHub验证授权信息后重定向到服务器接口返回Code
router.get("/auth/github/callback",async(ctx)=>{const{code}=ctx.query;console.log("code:",code);//TODO其他部分待实现});第三步:服务器通过code换取accesstoken
router.get("/auth/github/callback",async(ctx)=>{const{code}=ctx.query;console.log("code:",code);constparams={client_id:config.client_id,client_secret:config.client_secret,code:code,};letret=awaitaxios.post("https://github.com/login/oauth/access_token",params);const{access_token}=querystring.parse(ret.data);console.log("access_token:",access_token);//TODO其他部分待实现});第四步:使用accesstoken获取用户信息,服务器做登录态处理
router.get("/auth/github/callback",async(ctx)=>{const{code}=ctx.query;console.log("code:",code);constparams={client_id:config.client_id,client_secret:config.client_secret,code:code,};letret=awaitaxios.post("https://github.com/login/oauth/access_token",params);const{access_token}=querystring.parse(ret.data);console.log("access_token:",access_token);ret=awaitaxios.get(`https://api.github.com/user`,{headers:{Authorization:`token${access_token}`},});console.log("user:",ret.data);ctx.body=`<h1>Hello${ret.data.login}</h1><img src="${ret.data.avatar_url}">`;});补充Html部分:
