Question

我们目前使用blobstore.create_upload_url创建要在前端使用的上传网址，请参阅this video。但是，随着谷歌推出谷歌云存储（GCS），我想使用GCS而不是blobstore。我们目前使用的是blobstore.create_upload_url，但我在GCS文档中找不到任何相同的内容。我错过了什么吗？有没有更好的方法从前端上传文件到GCS？

如果您将提供gs_bucket_name到blobstore.create_upload_url文件将存储在GCS而不是blobstore中，官方文档中对此进行了描述：Using the Blobstore API with Google Cloud Storage

blobstore.create_upload_url(
                success_path=webapp2.uri_for('upload'),
                gs_bucket_name="mybucket/dest/location")

您可以查看在webapp2中进行的简单上传处理程序实现

from google.appengine.ext import blobstore
from google.appengine.ext.webapp import blobstore_handlers
import webapp2
import cloudstorage as gcs


class Upload(blobstore_handlers.BlobstoreUploadHandler):
    """Upload handler
    To upload new file you need to follow those steps:

    1. send GET request to /upload to retrieve upload session URL
    2. send POST request to URL retrieved in step 1
    """
    def post(self):
        """Copy uploaded files to provided bucket destination"""
        fileinfo = self.get_file_infos()[0]
        uploadpath = fileinfo.gs_object_name[3:]
        stat = gcs.stat(uploadpath)

        # remove auto generated filename from upload path 
        destpath = "/".join(stat.filename.split("/")[:-1])

        # copy file to desired location with proper filename 
        gcs.copy2(uploadpath, destpath)
        # remove file from uploadpath
        gcs.delete(uploadpath)

    def get(self):
        """Returns URL to open upload session"""

        self.response.write(blobstore.create_upload_url(
            success_path=uri_for('upload'),
            gs_bucket_name="mybucket/subdir/subdir2/filename.ext"))

什么是blobstore的GCS等价物＆＃34; Create_upload_url＆＃34;？
