如何获取通过BlobstoreUploadHandler上传的文件的FileInfo / gcs file_name？

问题描述

blobstore.parse_file_info（cgi.FieldStorage（）['file']）方法对BlobstoreUploadHandler不起作用，FieldStorage似乎用于常规上传。

blob_info中没有gcs文件名信息，self.get_uploads提供的常规blob_info提供了一个gbs文件名信息似乎只有一个blob_key可以使用常规方法访问，但似乎只有一个blob_key为未来最安全的赌注

如何使用gs_bucket_name参数从blobstore.create_upload_url上传到url的文件的gcs file_name？

解决方案

class UploadAPI（blobstore_handlers.BlobstoreUploadHandler）：
def post（self）：
file_info = self.get_file_infos（）[0]

rtn_data = {
filename：file_info.filename，
content_type：file_info.content_type，
creation ：file_info.creation，
size：file_info.s ize，
md5_hash：file_info.md5_hash，
gs_object_name：file_info.gs_object_name
}


我在代码中找到了用法，但我也找不到文档。

在
说。

但是没有任何与 FileInfo 相关的信息，我可以在 BlobstoreUploadHandler

blobstore.parse_file_info(cgi.FieldStorage()['file']) method doesn't work for BlobstoreUploadHandler, the FieldStorage seems to be for regular uploads

There is no gcs filename information inside the blob_info that the regular blob_info from self.get_uploads provides

It seems only a blob_key can be accessed using the regular methods, however a gcs file_name seems to be the safest bet for future

How can I get gcs file_name of a file uploaded to an url from blobstore.create_upload_url with gs_bucket_name argument?

解决方案

class UploadAPI(blobstore_handlers.BlobstoreUploadHandler):
    def post(self):
        file_info = self.get_file_infos()[0]

        rtn_data = {
            "filename": file_info.filename,
            "content_type": file_info.content_type,
            "creation": file_info.creation,
            "size": file_info.size,
            "md5_hash": file_info.md5_hash,
            "gs_object_name": file_info.gs_object_name
        }

I did find the usage in code, but I cannot find document either.

Inhttps://developers.google.com/appengine/docs/python/blobstore/fileinfoclass said.

But there is nothing related to FileInfo I can find in document of BlobstoreUploadHandlerhttps://developers.google.com/appengine/docs/python/tools/webapp/blobstorehandlers
