I try to find a way to upload a PDF file, generated by a php/MySQL server to my Google Storage bucket. The URL is simple : www.my_domain.com/file.pdf . I tried with the code below , but I'm having some issues to make it work. The error is : path (fs.createWriteStream(destination)) must be a string or Buffer. Thanks in advance for your help !
const http = require('http');
const fs = require('fs');
const {Storage} = require('@google-cloud/storage')
const gcs = new Storage({
keyFilename: 'my_keyfile.json'
})
const bucket = gcs.bucket('my_bucket.appspot.com');
const destination = bucket.file('file.pdf');
var theURL = 'https://www.my_domain.com/file.pdf';
var download = function() {
var file = fs.createWriteStream(destination);
var request = http.get(theURL, function(response) {
response.pipe(file);
file.on('finish', function() {
console.log("File uploaded to Storage")
file.close();
});

推荐答案
我终于找到了解决方案:
I finally found a solution :
const http = require('http');
const fs = require('fs');
const {Storage} = require('@google-cloud/storage')
const gcs = new Storage({
keyFilename: 'my_keyfile.json'
})
const bucket = gcs.bucket('my_bucket.appspot.com');
const destination = os.tmpdir() + "/file.pdf";
const destinationStorage = path.join(os.tmpdir(), "file.pdf");
var theURL = 'https://www.my_domain.com/file.pdf';
var download = function () {
var request = http.get(theURL, function (response) {
if (response.statusCode === 200) {
var file = fs.createWriteStream(destination);
response.pipe(file);
file.on('finish', function () {
console.log('Pipe OK');
bucket.upload(destinationStorage, {
destination: "file.pdf"
}, (err, file) => {
console.log('File OK on Storage');
});
file.close();
});
}
});
}
