Firebase + Ionic3 错误:disallowed_useragent [英] Firebase + Ionic3 Error: disallowed_useragent

问题描述

关于这个主题还有几个其他问题/答案，但他们没有将 Firebase 与 Ionic 一起使用.我刚刚切换到新的 Ionic View，现在，我在旧的 Ionic View 中的应用程序可以工作，而新的 Ionic View 给了我这个众所周知的错误:

<块引用>

403 错误 - 这是一个错误.错误:disallowed_useragent 他的用户代理不允许向 Google 发出 OAuth 授权请求，因为它被归类为嵌入式用户代理(也称为网络视图).呸呸呸

在我的代码中，我注入了 Firebase AuthProvider 并使用 angularfire2 进行连接，它看起来像

 private getProvider(from: string): AuthProvider {切换(从){案例推特":返回新的 firebase.auth.TwitterAuthProvider();case 'facebook': 返回新的 firebase.auth.FacebookAuthProvider();case 'github':返回新的 firebase.auth.GithubAuthProvider();case 'google':返回新的 firebase.auth.GoogleAuthProvider();}}登录(来自:字符串){this.afAuth.auth.signInWithPopup(this.getProvider(from))...

同样，这在浏览器或旧的 Ionic 中效果很好，但不适用于新的 Ionic 视图.我确实有一个相当大的带有通用 OAuth 连接的库，但我认为使用 Firebase 的一个重要原因是我们不再需要使用这些库并自己管理用户.

有没有办法通过 Ionic 在 iOS/Android 应用上进行 Firebase 身份验证?

解决方案

您应该按照 这篇文章.我认为不支持 signInWithPopup 方法，您应该尝试使用 signInWithRedirect 代替.

通过将以下内容添加到我的 config.xml 中，我设法修复了 disallowed_useragent 错误:

There are a couple of other questions/answers on this topic, but they were not using Firebase with Ionic. I just switched to the new Ionic View and right now today, my app in the old Ionic View works while the new Ionic View gives me this well known error:

403 Error - Thats an error. Error: disallowed_useragent his user-agent is not permitted to make an OAuth authorization request to Google as it is classified as an embedded user-agent (also known as a web-view). blah blah blah

In my code I inject the Firebase AuthProvider and use angularfire2 to connect and it looks like

  private getProvider(from: string): AuthProvider {
  switch (from) {
    case 'twitter': return new firebase.auth.TwitterAuthProvider();
    case 'facebook': return new firebase.auth.FacebookAuthProvider();
    case 'github': return new firebase.auth.GithubAuthProvider();
    case 'google': return new firebase.auth.GoogleAuthProvider();
  }
}

  signIn(from: string) {
    this.afAuth.auth.signInWithPopup(this.getProvider(from))
. . .

Again, this works great in the browser or old Ionic but not the new Ionic View. I do have a fairly big library with general OAuth connections, but I thought that one of the great reasons to use Firebase is that we would no longer have to use those libraries and manage users ourselves.

Is there a way to do the Firebase auth on an iOS/Android app via Ionic?

解决方案

You should follow the instructions in this article. I don't think signInWithPopup method is supported, you should try signInWithRedirect instead.

I managed to fix the disallowed_useragent error by adding the following to my config.xml:

<preference name="OverrideUserAgent" value="Mozilla/5.0 Google" />
