问题描述
我已经通过JS通过Google云端存储将文件成功上传到Firebase的存储空间!我注意到的是,与直接上传的文件不同的是,通过Google Cloud上传的文件只有一个存储位置URL,它不是一个完整的URL,这意味着它不能被读取!我想知道是否有一种方法可以为Firebase实际存储的下载网址部分生成完整的上传网址。
I have successfully uploaded files to Firebase's storage via Google Cloud Storage through JS! What I noticed is that unlike files uploaded directly, the files uploaded through Google Cloud only have a Storage Location URL, which isn't a full URL, which means it cannot be read! I'm wondering if there is a way to generate a full URL on upload for the "Download URL" part of Firebase's actual storage.
正在使用的代码:
var filename = image.substring(image.lastIndexOf("/") + 1).split("?")[0];
var gcs = gcloud.storage();
var bucket = gcs.bucket('bucket-name-here.appspot.com');
request(image).pipe(bucket.file('photos/' + filename).createWriteStream(
{metadata: {contentType: 'image/jpeg'}}))
.on('error', function(err) {})
.on('finish', function() {
console.log(imagealt);
});
推荐答案
使用GCloud客户端时, href =https://googlecloudplatform.github.io/gcloud-node/#/docs/v0.36.0/storage/file?method=getSignedUrl =nofollow> getSignedUrl()
下载文件,如下所示:
When using the GCloud client, you want to use getSignedUrl()
to download the file, like so:
bucket.file('photos/' + filename).getSignedUrl({
action: 'read',
expires: '03-17-2025'
}, function(err, url) {
if (err) {
console.error(err);
return;
}
// The file is now available to read from this URL.
request(url, function(err, resp) {
// resp.statusCode = 200
});
});
