Firebase 函数调用返回“NOT_FOUND”异常。 （安卓、科特林）

Question

我正在尝试在 Kotlin Android 应用程序中使用 Firebase 函数将消息从客户端设备发送到另一个客户端设备。

index.js 中的 Firebase 函数

 exports.callUser = functions.https.onCall((data) => {
   console.log('Call request received.');
   // Message text passed from the client.
   const registrationToken = data.registrationToken;
   functions.logger.log('Calling', registrationToken);
   var message = {
     data: {
       doctor: 'foo',
       patient: 'bar',
       room: 'foobar'
     },
     token: registrationToken
   };
   return admin.messaging().send(message)
       .then((response) => {
           console.log('Successfully sent incoming call message:', response);
           return "Sent";
       })
       .catch((error) => {
           console.log('Error sending message:', error);
           throw new functions.https.HttpsError('unknown', error.message, error);
       });
 });

Firebase函数客户端调用

private fun makeCall(registrationToken: String): Task<String> {
    // Create the arguments to the callable function.
    val data = hashMapOf(
        "registrationToken" to registrationToken
    )
    Log.d(TAG, "callUser data input: $data")
    return Firebase.functions
        .getHttpsCallable("callUser")
        .call(data)
        .continueWith { task ->
            val result = task.result?.data as String
            result
        }
}

函数的异常处理

makeCall(registrationToken)
.addOnCompleteListener(OnCompleteListener { task ->
    if (!task.isSuccessful) {
        val e = task.exception
        if (e is FirebaseFunctionsException) {
            val code = e.code
            val details = e.details
            Log.w(TAG, "$code")
        }
        // [START_EXCLUDE]
        Log.w(TAG, "addMessage:onFailure", e)
        showSnackbar("An error occurred.")
        return@OnCompleteListener
        // [END_EXCLUDE]
    }
    // [START_EXCLUDE]
    val result = task.result
    Log.d(TAG,"MakeCall result: $result")
    val intent = Intent(activity, VideoActivity::class.java)
    startActivity(intent)
    // [END_EXCLUDE]
})

我已经能够编写简单的 https.onRequest() 函数，该函数按预期工作，但我无法弄清楚我在这个回调函数中做错了什么。

我正在使用 Firebase 模拟器进行测试，没有任何日志，因为该函数从未成功调用。

Answer 1

这是因为我使用的是 Firebase 模拟器。如果您想使用模拟器，在访问“Firebase.functions”之前，必须包含“FirebaseFunctions.getInstance().useFunctionsEmulator("http://10.0.2.2:5001")”。
