[英]Fetching from firestore and Firebase functions timeout
I have a simple function that I am testing locally on the emulator.我有一个简单的 function,我正在模拟器上进行本地测试。
exports.sendNotification = functions.https.onRequest(() => {
firebase
.firestore()
.collection("Users")
.get()
.then((snapshot) => {
snapshot.docs.forEach((doc) => {
console.log(doc.id, doc.data());
});
});
});
When I execute the function, it works fine, but shortly after I get this message:当我执行 function 时,它工作正常,但在我收到此消息后不久:
functions: Your function timed out after ~60s. To configure this timeout, see
https://firebase.google.com/docs/functions/manage-functions#set_timeout_and_memory_allocation.
> C:\Users\myusername\AppData\Roaming\npm\node_modules\firebase-tools\lib\emulator\functionsEmulatorRuntime.js:618
> throw new Error("Function timed out.");
> ^
>
> Error: Function timed out.
> at Timeout._onTimeout (C:\Users\myusername\AppData\Roaming\npm\node_modules\firebase-tools\lib\emulator\functionsEmulatorRuntime.js:618:19)
> at listOnTimeout (node:internal/timers:557:17)
> at processTimers (node:internal/timers:500:7)
my expectation was that the function would just end normally since its at the end of the function, is this message saying that I need to do something to indicate the function has finished?我的期望是 function 会正常结束,因为它在 function 结束时,这条消息是说我需要做些什么来表明 function 已经结束吗? Do I need to change something especially when pushing to production?
我是否需要更改某些内容,尤其是在投入生产时?
You must terminate a HTTP function by sending back a response otherwise it'll run until it times out.您必须通过发回响应来 终止 HTTP function否则它将一直运行直到超时。 Try refactoring your code like this:
尝试像这样重构您的代码:
exports.sendNotification = functions.https.onRequest((req, res) => {
// add req, res in functions parameters ^^^
return firebase
.firestore()
.collection("Users")
.get()
.then((snapshot) => {
snapshot.docs.forEach((doc) => {
console.log(doc.id, doc.data());
});
// Return response
return res.json({ data: snapshot.docs.map(d => d.data()) })
});
});
