Question

我实质上是在尝试建立一个网站，该网站通过firebase对用户的GitHub帐户进行身份验证，然后将其用户名保存在数据库中-我特别需要此用户名。我可以进行身份验证，但是firebase似乎无法访问用户名，只能访问电子邮件，显示名称等内容。目前，我只想将用户名另存为变量

我遇到了这个问题：https://developer.github.com/v3/users/#get-the-authenticated-user 我假设“登录名”是用户名？不过，我对事物还比较陌生，无法找到任何清晰的示例说明如何使用Firebase的令牌访问此信息。作为参考，我有一个与app.js链接的index.html，其中包含我的所有身份验证代码。

var provider = new firebase.auth.GithubAuthProvider();
    provider.addScope('read:user');
    //get elements
    const authenticateBtn = document.getElementById('authbtn');

    //add login event
    authenticateBtn.addEventListener('click', e=>{

        firebase.auth().signInWithPopup(provider).then(function(result) {
        // This gives you a GitHub Access Token. You can use it to access the GitHub API.
        var token = result.credential.accessToken;

        // The signed-in user info.
        var user = result.user;

        //what I want to get
        //var Username = ; 

        //some data I am able to get
        var displayName = user.displayName;
        var email = user.email;
        var emailVerified = user.emailVerified;
        var photoURL = user.photoURL;
        var isAnonymous = user.isAnonymous;
        var uid = user.uid;
        var providerData = user.providerData;

        //where I want to print the username
        //console.log(userName);


        // ...
        }).catch(function(error) {
        // Handle Errors here.
        var errorCode = error.code;
        var errorMessage = error.message;
        // The email of the user's account used.
        var email = error.email;
        // The firebase.auth.AuthCredential type that was used.
        var credential = error.credential;
        // ...
        });
    })

我真的只需要初学者说明我想做的事情是否可能，如果可以的话，确切地说明我在项目中的什么地方需要什么代码。谢谢！

所以我最终从朋友那里得到了一些帮助，这是我的解决方法：

firebase.auth().signInWithPopup(provider).then(function(result) {

        // This gives you a GitHub Access Token. You can use it to access the GitHub API.
        var token = result.credential.accessToken;
        // The signed-in user info.

        var user = result.user;
        var username;
        var obj;

        const Http =  new XMLHttpRequest();
        Http.open("GET", "https://api.github.com/user?access_token="+token);
        Http.send();

        Http.onreadystatechange=function(){
            if(this.readyState==4 && this.status==200){
                obj = JSON.parse(Http.responseText);
                username = obj.login;
                console.log(username);

            }
        }
}

有没有办法获得经过Firebase认证的github用户的用户名
