问题描述

我试图找到一种将php/MySQL服务器生成的PDF文件上传到我的Google存储桶的方法. URL很简单:www.my_domain.com/file.pdf.我尝试使用下面的代码，但是遇到一些问题使其无法正常工作.错误是:path(fs.createWriteStream(destination))必须是字符串或Buffer.预先感谢您的帮助！

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

firebase-admin(从v7.0.0开始)使用google-cloud/storage v2.3.0，其中

firebase-admin, as of v7.0.0, uses google-cloud/storage v2.3.0, which can no longer accept file URLs on bucket.upload.

我想我也将分享我的解决方案.

I figured I would share my solution as well.

const rq = require('request');

// filePath = File location on google storage bucket
// fileUrl = URL of the remote file

let bucketFile = bucket.file(filePath);
const fileWriteStream = bucketFile.createWriteStream();
let rqPipe = rq(fileUrl).pipe(fileWriteStream);

// And if you want the file to be publicly readable
rqPipe.on('finish', async () => {
  await bucketFile.makePublic();
});
