从android调用云函数admin.auth().createUser()不起作用

Question

我正试图从一个不起作用的Android应用程序中调用谷歌云函数(部署后的第一次调用90%起作用，但随后的调用失败，firebase日志控制台上也没有显示任何内容(。

public Task<String> myCloudFunction() {
return FirebaseFunctions.getInstance()
.getHttpsCallable("createUser")
.call(data)
.continueWith(task -> {
String result = (String) task.getResult().getData();
return result;
});
}

功能面板中的端点https://us-central1-xyz:555.cloudfunctions.net/createUser

我就是这么称呼它的。

public void callCloudFunction() {
createFirebaseUserAccount.myCloudFunction()
.addOnCompleteListener(new OnCompleteListener<String>() {
@Override
public void onComplete(@NonNull Task<String> task) {
if (!task.isSuccessful()) {
Exception e = task.getException();
if (e instanceof FirebaseFunctionsException) {
FirebaseFunctionsException ffe = (FirebaseFunctionsException) e;
FirebaseFunctionsException.Code code = ffe.getCode();
Object details = ffe.getDetails();
} else {
Timber.d(task.getResult());
}
}
}
});
}

以下是云功能：$GOOGLE_APPLICATION_CREDENTIALS指向包含私钥的service_key.json文件。

admin.initializeApp({
credential: admin.credential.applicationDefault(),
databaseURL: "https://XYZ.firebaseio.com"
});
exports.createUser = functions.https.onCall((data, context) => {
const callerEmail = data.email;
const callerPassword = data.password;
const callerDisplayName = data.displayName;
return admin.auth().createUser({ 
email: callerEmail,
emailVerified: false,
password: callerPassword,
displayName: callerDisplayName,
disabled: false
}).then(userRecord => {
// See the UserRecord reference doc for the contents of userRecord.
console.log("Successfully created new user:", userRecord.uid);
return userRecord.uid;
}).catch(error => {
console.log("Error creating new user ", error);
return error;
});
});

您不会从包含要发送到客户端的数据的函数返回promise。事实上，你根本没有通过任何东西。相反，您应该从异步工作返回promise链：

return admin.auth().createUser({ 
email: callerEmail,
emailVerified: false,
password: callerPassword,
displayName: callerDisplayName,
disabled: false
}).then(userRecord => {
// See the UserRecord reference doc for the contents of userRecord.
console.log("Successfully created new user:", userRecord.uid);
return userRecord.uid;
}).catch(error => {
console.log("Error creating new user ", error);
return error;
});

在整件事之前注意新的return。为了有效地使用云函数，您肯定应该花一些时间来了解JavaScript承诺是如何工作的，如果不遵守它们的规则和约定，它们将无法正常工作。
