Java Firebase管理sdk:IllegalArgumentException，Premissions.checkArgument

我得到的错误如下：

我意识到这个堆栈不是很有用。我已经在AdminSDK中调试过了。它正确地读取了我的服务json，

FirebaseAuth.getInstance（）

不为空，我可以看到我的项目id设置正确

这就是我初始化的方式：

if(FirebaseApp.getApps().size() > 0) {
            System.out.println("initialized already ");
            return;
        }

        FirebaseOptions options = null;
        try {
            System.out.println("try initializing");
            options = new FirebaseOptions.Builder()
                    .setCredentials(GoogleCredentials.fromStream(gservicesConfig.getInputStream()))
                    .setDatabaseUrl("https://pamperanywhere.firebaseio.com")
                    .build();
        } catch (IOException e) {
            e.printStackTrace();
        }
        FirebaseApp.initializeApp(options);
        return;

以下是我测试令牌的方式：

@Test
public void testFire2() {
    String idToken = "REFRESH TOKEN FROM FIREBASE";
    if(!StringUtils.isEmpty(idToken)) {
        FirebaseToken firebaseToken = null;
        if(FirebaseAuth.getInstance() == null) {
            System.out.println("FirebaseAuth.getInstance() == null");
        }
        try {
            firebaseToken = FirebaseAuth.getInstance().verifyIdToken(idToken, true);
        } catch (IllegalArgumentException e) {
            System.out.println("exception+IllegalArgumentException");
            e.printStackTrace();
        } catch (FirebaseAuthException e) {
            System.out.println("exception+FirebaseAuthException");
            e.printStackTrace();
        }
        if (firebaseToken == null) {
            System.out.println("firebaseToken == null");
        }
    }
}

我不知道为什么它会抛出

非法argumentexception

。我可以登录到应用程序罚款（前端），我看到我的刷新令牌（前端），但在管理方面，它给了我这个问题。我确信我传递了正确的令牌，因为我可以登录并查看令牌（前端）

Maven是：

    <dependency>
        <groupId>com.google.firebase</groupId>
        <artifactId>firebase-admin</artifactId>
        <version>6.2.0</version>
    </dependency>

com.google.firebase
firebase管理员
6.2.0

感谢您的帮助。

ID令牌应该是有效的JWT，包含3个段（用点分隔）。刷新令牌当然不是这样。因此，底层令牌解析器由于上述断言错误而失败。下面是来自GoogleAPI客户端的相关代码。基本上，它在给定的标记字符串中找不到任何点

public JsonWebSignature parse(String tokenString) throws IOException {
      // split on the dots
      int firstDot = tokenString.indexOf('.');
      Preconditions.checkArgument(firstDot != -1);
      ...

有一个听众：

firebase.auth().onIdTokenChanged((user: firebase.User) => {
      console.log("onIdTokenChanged");
      if(user && user.uid) {
        user.getIdToken(false)
        .then((data: any) => {
          console.log("data: ", data);
          this.idToken = data;
        });
      }      
    });

每一小时调用一次。我想我必须自己实现这个逻辑！

来自官方；上面是来自Ionic2/Angular2的，我在dataServiceProvider的构造函数中有它

firebase.auth().onIdTokenChanged(function(user) {
  if (user) {
    // User is signed in or token was refreshed.
  }
});

所以在单页应用程序中，我每次都需要从firebase获取令牌？
