Question

所以我对离子相对较新，我试图将用户添加到实时firebase数据库。用户需要提供更多详细信息，而不仅仅是电子邮件和密码（例如他们的名字，姓氏，地址，电话号码等），因为我稍后需要详细信息。

我正在关注一个教程，我相信由于教程略显陈旧，我无法通过此错误使函数正常工作：

错误：未捕获（在承诺中）：错误：Reference.child失败：第一个参数是无效路径=＆＃34; profile / $ {auth.uid}＆＃34;。路径必须是非空字符串，并且不能包含＆＃34;。＆＃34;，＆＃34;＃＆＃34;，＆＃34; $＆＃34;，＆＃34; [＆＃34;，或＆＃34;]＆＃34; 错误：Reference.child失败：第一个参数是无效路径=＆＃34; profile / $ {auth.uid}＆＃34;。路径必须是非空字符串，并且不能包含＆＃34;。＆＃34;，＆＃34;＃＆＃34;，＆＃34; $＆＃34;，＆＃34; [＆＃34;，或＆＃34;]＆＃34;

我不完全确定我做错了什么，所以任何帮助都会受到赞赏。我的代码在

If you pass variable inside the path like this ${uid},

你不能使用撇号（'profile / $ {auth.uid}'），所以你需要使用严重重音 （``）< / strong>（profile/${auth.uid}）。您也可以使用这种方式（“profile /”+ auth.uid）

createProfile() { this.afAuth.authState.take(1).subscribe(auth => { this.afDatabase.object(`profile/${auth.uid}`).set(this.profile) .then(() => this.navCtrl.setRoot(TabsPage)); }) }

也尝试这个，

createProfile() { this.afAuth.authState.take(1).subscribe(auth => { this.afDatabase.database.ref('/profile').child(auth.uid) .set(this.profile).then(() => this.navCtrl.setRoot(TabsPage)); }) }
