英文:
Firebase Cloud Function: An issue with Auth callbacks
问题
我有两个Auth回调函数，一个在用户创建时触发，另一个在用户删除时触发。每个回调都成功触发，但产生相同的错误：“TypeError: handler is not a function at cloudFunction”。看起来我在回调函数的语法上有误，但我找不到适用于V1函数的正确示例。请帮忙，谢谢。
另外：我如何将这些函数部署到europe-west1而不是us-central1，V1函数是否支持这个功能？
const functions = require("firebase-functions"); // v1
const { initializeApp } = require("firebase-admin/app");
initializeApp();
const db = getFirestore();
exports.authUserCreated = functions.auth.user().onCreate({ region: "europe-west1" }, (user) => {
const userEmail = user.email;
const userId = user.uid;
return db.collection("users").doc(userId).update({ createdAt: FieldValue.serverTimestamp(), email: userEmail });
});
exports.authUserDeleted = functions.auth.user().onDelete({ region: "europe-west1" }, (user) => {
const userId = user.uid;
return db.collection("users").doc(userId).delete();
});
英文:
I have two Auth callbacks, when a user was created and deleted. Each callback fired successfully, but produces the same error: TypeError: handler is not a function at cloudFunction. It seems I was wrong with callbacks' syntax, but I can't find right example for V1 functions. Please help, thanks.
Also: how can I deploy these funcs to europe-west1 insted of us-central1, is it possible for V1 functions?
const functions = require("firebase-functions"); // v1
const {initializeApp} = require("firebase-admin/app");
initializeApp();
const db = getFirestore();
exports.authUserCreated = functions.auth.user().onCreate({region: "europe-west1"}, (user) => {
const userEmail = user.email;
const userId = user.uid;
return db.collection("users").doc(userId).update({createdAt: FieldValue.serverTimestamp(), email: userEmail});
});
exports.authUserDeleted = functions.auth.user().onDelete({region: "europe-west1"}, (user) => {
const userId = user.uid;
return db.collection("users").doc(userId).delete();
});

你不能将对象作为onCreate()的第一个参数传递。这是v2语法，但您正在编写v1函数。请按照文档中的示例进行操作：
exports.sendWelcomeEmail = functions.auth.user().onCreate((user) => {
// ...
});
只有一个参数 - 处理程序函数。
如果您想要在v1类型的函数上设置区域，也有相关的文档：
exports.myStorageFunction = functions
.region('europe-west1')
.storage
.object()
.onFinalize((object) => {
// ...
});
因此，您需要执行类似以下的操作：
exports.authUserCreated = functions
.region("europe-west1")
.auth
.user()
.onCreate(user => { ... })
您还可以查看firebase-functions模块的API文档以获取更多信息。
英文:
You can't pass an object as the first argument to onCreate(). That's v2 syntax, but you are writing a v1 function. Follow the example in the documentation:
exports.sendWelcomeEmail = functions.auth.user().onCreate((user) => {
// ...
});
There is only one argument - the handler function.
If you want to set the region on a v1 type function, there is documentation for that as well:
exports.myStorageFunction = functions
.region('europe-west1')
.storage
.object()
.onFinalize((object) => {
// ...
});
So you will need to do something like this:
exports.authUserCreated = functions
.region("europe-west1")
.auth
.user()
.onCreate(user => { ... })
You might also want to review the API documentation for the firebase-functions module.
