重新启动应用程序时，GIDSignIn.sharedInstance().currentUser为零 [英] GIDSignIn.sharedInstance().currentUser nil when relaunching app

问题描述

最初，我在检查是否存在问题，以查看是否已将数据保存到钥匙串中.我找到了这篇文章，并遵循了BhavinBhadani的建议:

Initially I was having a problem with the check to see if we have saved data into the keychain. I found this post and followed the suggestion by BhavinBhadani:

无论何时检查([GIDSignIn sharedInstance] .hasAuthInKeychain)， 在此之前，请先添加您的登录范围.

Whenever you check if ([GIDSignIn sharedInstance].hasAuthInKeychain) , before that add your sign in scopes..

这解决了我的第一个问题，即GIDSignIn.sharedInstance().hasAuthInKeychain()在用户之前成功登录然后终止应用程序并重新运行之后返回true.

This has solved my first problem of GIDSignIn.sharedInstance().hasAuthInKeychain() returning true after the user has logged in successfully before and then has killed app and re runs.

但是现在我正在执行以下操作:

However now I am doing the following:

let signIn = GIDSignIn.sharedInstance()
signIn.scopes = [Constants.GOOGLE_CLIENT_SCOPE, Constants.GOOGLE_OIDC_SCOPE]

if GIDSignIn.sharedInstance().hasAuthInKeychain() {
    print("We have saved in keychain")

    if let u = GIDSignIn.sharedInstance().currentUser {
        getData(dataApi)
    }
    else {
        // THIS CODE IS BEING SUCCESSFULLY HIT
        GIDSignIn.sharedInstance().signInSilently()
        getApplicationData(dataApi)
    }
}

但是即使这样做:GIDSignIn.sharedInstance().signInSilently() GIDSignIn.sharedInstance().currentUser也为零.

However even after doing: GIDSignIn.sharedInstance().signInSilently() the GIDSignIn.sharedInstance().currentUser is nil.

有人成功使用signInSilently()再次填充了currentUser数据吗?

Has anyone successfully used signInSilently() to populate the currentUser data again?

推荐答案

我在git中指出该问题，您还需要在像这样检查hasAuthInKeychain之前添加作用域.你

I make a point in that issue in git that you also need to add scopes before check hasAuthInKeychain like this .. this works for me and hope same for you

 let signIn = GIDSignIn.sharedInstance()
signIn.scopes = ["https://www.googleapis.com/auth/plus.login","https://www.googleapis.com/auth/plus.me"]

  if (signin.hasAuthInKeychain) {
        print("Signed in");
  } else {
        print("Not signed in");
  }

确保在GIDSignIn.sharedInstance().signInSilently()之后，调用getApplicationData(dataApi)填充数据会有一些延迟.

make sure after GIDSignIn.sharedInstance().signInSilently(), there is some delay to call getApplicationData(dataApi) to populate data.
