我有一个 flutter 应用程序，现在我需要在我的应用程序中接受付款，并且我想检查付款是否是通过使用 firebase 函数进行的，但我不断收到未经验证的错误。
我添加了应用程序检查，因为这是实现我想要的支付功能所必需的。我在 appcheck 中发现我的请求已得到验证，所以我认为这不是问题所在。但如果我调用该函数，我会收到错误 [firebase_functions/unauthenticated} UNAUTHENTICATED。我已经更改了整个函数只是为了测试，但我仍然遇到相同的错误：
索引.js
const admin = require("firebase-admin");
admin.initializeApp();
exports.testFunction = functions.https.onCall((data, context) => {
console.log("Auth context:", context.auth);
console.log("App Check token:", context.app);
// Check if the user is authenticated
if (!context.auth) {
console.error("User is not authenticated.");
throw new functions.https.HttpsError(
"failed-precondition",
"The function must be called while authenticated.",
);
}
// Check if App Check is enabled and working
if (!context.app) {
console.error("App Check token is missing or invalid.");
throw new functions.https.HttpsError(
"failed-precondition",
"App Check is not verified or missing.",
);
}
// Return a simple success message
return {message: "Authentication and App Check are working!"};
});
这是我测试 firebase 功能的颤动屏幕：
import 'package:flutter/material.dart';
import 'package:cloud_functions/cloud_functions.dart';
import 'package:firebase_auth/firebase_auth.dart';
class TestFunctionScreen extends StatefulWidget {
@override
_TestFunctionScreenState createState() => _TestFunctionScreenState();
}
class _TestFunctionScreenState extends State<TestFunctionScreen> {
String _result = "Press the button to test Firebase Function";
Future<void> testFunction() async {
try {
// Ensure the user is logged in
User? user = FirebaseAuth.instance.currentUser;
if (user == null) {
setState(() {
_result = "User not logged in. Please log in and try again.";
});
return;
}
print("Authenticated user: ${user.uid}");
// Call Firebase Function
final HttpsCallable callable = FirebaseFunctions.instance.httpsCallable('testFunction');
final response = await callable.call();
setState(() {
_result = "Function Response: ${response.data}";
});
} catch (e, stackTrace) {
print("Error calling function: $e");
print(stackTrace);
setState(() {
_result = "Error: $e";
});
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Test Firebase Function"),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text(
_result,
textAlign: TextAlign.center,
),
SizedBox(height: 20),
ElevatedButton(
onPressed: testFunction,
child: Text("Test Firebase Function"),
),
],
),
),
);
}
}
这是我启动应用程序时的日志，直到我按下测试 firebase 功能按钮。

您需要在客户端启用应用程序检查 - 或在云功能端禁用它。
更改：
exports.testFunction = functions.https.onCall((data, context) => {
致：
exports.testFunction = functions.https.onCall({ enforceAppCheck: false }, async (request) => {
或者传递类似的东西作为
.getHttpsCallable(name, options)HttpsCallableOptions.Builder().setLimitedUseAppCheckTokens(true).build()
HttpsCallableOptions
