java - 如何修复 java.util.concurrent.ExecutionException :

Question

我在 Google Play Android Vitals 上看到了一些来自以下代码的崩溃报告:

val currentUser = auth.currentUser

            if (currentUser != null) {
                sessionToken = Tasks.await(currentUser.getIdToken(true)).token
                newRequest = request
                        .newBuilder()
                        .header(AUTHORIZATION, "$BEARER $sessionToken")
                        .build()
            } else {
                newRequest = request
                        .newBuilder()
                        .build()
            }

出现问题的行是这样的:sessionToken = Tasks.await(currentUser.getIdToken(true)).token

auth 是 FirebaseUser 对象。该代码位于拦截器中，它为需要它的请求添加授权 token 。

我不知道如何解决这个问题。我正在考虑用

包装所有代码

syncronized(this) {
       //here goes the code
}

但我不确定这是否能解决我的问题。

Answer 1

改变

val currentUser = auth.currentUser

到

val currentUser = FirebaseAuth.getInstance().currentUser

然后检查

if (currentUser != null) {
     //your code here
}

如果我的解决方案不能解决您的问题，请检查一下 它说

Caused by: java.util.concurrent.ExecutionException: com.google.firebase.auth.FirebaseAuthInvalidUserException: The user's credential is no longer valid

因此请使用有效的登录凭据。
