我下面在Google Cloud函数中有一个nodejs函数,该函数不断返回ESOCKETTIMEDOUT错误,并且连续执行而没有停止。
exports.generateTHUMBPIC = functions.storage.object('productpics').onFinalize((object, context) => {
// [START eventAttributes]
const fileBucket = object.bucket; // The Storage bucket that contains the file.
const filePath = object.name; // File path in the bucket.
const contentType = object.contentType; // File content type.
const resourceState = object.resourceState; // The resourceState is 'exists' or 'not_exists' (for file/folder deletions).
const metageneration = object.metageneration; // Number of times metadata has been generated. New objects have a value of 1.
const fileDir1 = path.dirname(filePath);
const fileName0 = path.basename(filePath);
const fileDir = fileDir1.replace('productpics/', '')
var listingid = fileDir.split("*")[1];
var userid = fileDir.split("*")[0];
var productid = fileDir.split("*")[2];
var thumbname = fileDir.split("*")[3]; // thumbnail 1 or 2 or 3
thumbarray.push(thumbname);
const thumbFilePath = path.normalize(path.join(fileDir1, `${THUMB_PREFIX}${productid}`));
const tempLocalFile = path.join(os.tmpdir(), filePath);
const tempLocalDir = path.dirname(tempLocalFile);
const tempLocalThumbFile = path.join(os.tmpdir(), thumbFilePath);
// [END eventAttributes]
// [START stopConditions]
// Exit if this is triggered on a file that is not an image.
if (!contentType.startsWith('image/')) {
console.log('This is not an image.');
return null;
}
// Exit if the image is already a thumbnail.
if (productid.startsWith(THUMB_PREFIX)) {
console.log('Already a Thumbnail.');
return null;
}
// Download file from bucket.
const bucket = gcs.bucket(fileBucket);
const file = bucket.file(filePath);
const thumbFile = bucket.file(thumbFilePath);
const metadata = {
contentType: contentType,
};
return mkdirp(tempLocalDir).then(() => {
// Download file from bucket.
return file.download({
destination: tempLocalFile
});
}).then(() => {
return spawn('convert', [tempLocalFile, '-thumbnail', `${THUMB_MAX_WIDTH}x${THUMB_MAX_HEIGHT}>`, tempLocalThumbFile], {
capture: ['stdout', 'stderr']
});
}).then(() => {
// console.log('Thumbnail created at', tempLocalThumbFile);
// Uploading the Thumbnail.
return bucket.upload(tempLocalThumbFile, {
destination: thumbFilePath,
metadata: metadata
});
}).then(() => {
fs.unlinkSync(tempLocalFile);
fs.unlinkSync(tempLocalThumbFile);
const config = {
action: 'read',
expires: '03-01-2500',
};
return Promise.all([
thumbFile.getSignedUrl(config),
file.getSignedUrl(config),
]);
}).then((results) => {
const thumbResult = results[0];
const originalResult = results[1];
const thumbFileUrl = thumbResult[0];
const fileUrl = originalResult[0];
var updates = {};
updates['Listings/' + listingid + "/" + thumbname + "thumb"] = thumbFileUrl;
return admin.database().ref().update(updates);
}).then(() => console.log('Thumbnail URLs saved to database.'));
});
这是完整的错误
ESOCKETTIMEDOUT 在ClientRequest。 (/user_code/node_modules/@google-cloud/storage/node_modules/request/request.js:816:19) 在ClientRequest.g(events.js:292:16) 在emitNone(events.js:86:13) 在ClientRequest.emit(events.js:185:7) 在TLSSocket.emitTimeout(_http_client.js:630:10) 在TLSSocket.g(events.js:292:16) 在emitNone(events.js:86:13) 在TLSSocket.emit(events.js:185:7) 在TLSSocket.Socket._onTimeout(net.js:348:8) 在ontimeout(timers.js:386:11)
是什么原因导致此错误并反复执行该函数而没有停止,我该如何解决?
