Firebase为电子邮件和密码提供了一个出色的预建身份验证系统。他们在此处发布了示例：https://github.com/firebase/quickstart-js/tree/master/auth
我正在努力理解的是如何将其集成到Angular / AngularFire应用程序中。
我可以将其复制并粘贴到'login.component.html / ts'文件中吗？
作为一个独立的解决方案，代码firebase提供了很好的效果并且运行良好。如果可能的话，将它放入Angular解决方案中会很棒。下面提供了代码的示例。任何帮助都会非常受欢迎。

angular-cli的应用？
如果是，最好在.angular-cli.json
中包含js文件 "scripts": [
"../node_modules/firebase/firebase.js"
],
然后在主要组件 app.component.ts （在contructor中）包含firebase配置
constructor() {
const config = {
apiKey: '',
authDomain: '',
databaseURL: '',
projectId: '',
storageBucket: '',
messagingSenderId: ''
};
firebase.initializeApp(config);
}
从现在开始，当firebase注入SPA时，您可以随时随地使用
例如在login.component.html
中<button (click)="signinWithGoogle()">
在login.component.ts
中public signinWithGoogle() {
const provider = new firebase.auth.GoogleAuthProvider();
firebase.auth().signInWithPopup(provider).then((response) => {
this.router.navigate(['/dashboard']);
});
}
发送电子邮件验证
firebase.auth().onAuthStateChanged((user) => {
user.sendEmailVerification();
});
