我试图在我的网站中添加firebase身份验证。我尝试了此代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

Sample FirebaseUI App
</title>
<!-- ******************************************************************************************* * TODO(DEVELOPER): Paste the initialization snippet from: * Firebase Console > Overview > Add Firebase to your web app. * ***************************************************************************************** -->
<script type="text/javascript">
// Initialize Firebase
var config = {

tosUrl: 'TOS.php' };
// Initialize the FirebaseUI Widget using Firebase.
var ui = new firebaseui.auth.AuthUI(firebase.auth());
// The start method will wait until the DOM is loaded.
ui.start('#firebaseui-auth-container', uiConfig);
</script>
</head>
<body>
<!-- The surrounding HTML is left untouched by FirebaseUI. Your app may use that space for branding, controls and other customizations.-->
<h1>

<div id="firebaseui-auth-container">

但是,当我访问Localhost时,它只是显示"欢迎来到我的真棒应用程序",而没有验证提供商,也没有看到容器。请帮忙注意:您也可以在本地主机中测试此代码。
您在控制台中遇到以下错误: Uncaught ReferenceError: firebase is not defined
您不包括Firebase JS CDN: <script src="https://www.gstatic.com/firebasejs/4.8.1/firebase.js"></script>
