[英]Firebase Auth & Firebase Auth With Facebook not working
Hello i'm trying to implement an firebase auth to my app. 您好,我正在尝试对我的应用程序执行Firebase身份验证。 but i does not seem to work. 但我似乎没有工作。 When i Submit the Form or click the Facebook Login it does nothing. 当我提交表单或单击Facebook登录名时,它什么也没有做。 I get this error: 我收到此错误:
Uncaught Error: The error you provided does not contain a stack trace. 未捕获的错误:您提供的错误不包含堆栈跟踪。

For popup sign-in visit the Facebook for Developers site, get the App ID and an App Secret for your app. 要进行弹出式登录,请访问Facebook for Developers网站,获取您的应用程序的应用程序ID和应用程序密钥。 If you don't want popup Check the code below: 如果不想弹出,请检查以下代码:
firebase.auth().signInWithRedirect(provider); firebase.auth().getRedirectResult().then(function(result) { if (result.credential) { // This gives you a Facebook Access Token. You can use it to access the Facebook API. var token = result.credential.accessToken; // ... } // The signed-in user info. var user = result.user; }).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; // ... });
This is incorrect: 这是不正确的:
firebase.auth().signInWithPopup(provider)
.then((result, error) => {
It should be: 它应该是:
firebase.auth().signInWithPopup(provider)
.then((result) => {
// Success.
}, (error) => {
// Error.
});
