本文介绍了如何获取通过BlobstoreUploadHandler上传的文件的FileInfo / gcs file_name?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

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。




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
