如何将图片从url上传到Blobstore？
|
如果blobstore blob，则Google App Engine文件API现在支持以编程方式创建。
我通过尝试通过http提取图像并将其存储到blobstore来解决此问题：
file_name = files.blobstore.create(mime_type=\'image/jpeg\')
image = urllib2.urlopen(url)
with files.open(file_name, \'a\') as f:
f.write(image) # LINE 142
files.finalize(file_name)
blob_key = files.blobstore.get_blob_key(file_name)
File \"/Users/willmerydith/repos/spam/admin.py\", line 142, in post
f.write(image)
File \"/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file.py\", line 364, in write
self._make_rpc_call_with_retry(\'Append\', request, response)
File \"/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file.py\", line 472, in _make_rpc_call_with_retry
_make_call(method, request, response)
File \"/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file.py\", line 229, in _make_call

File \"/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/apiproxy_stub.py\", line 80, in MakeSyncCall
if request.ByteSize() > self.__max_request_size:
File \"/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/files/file_service_pb.py\", line 1923, in ByteSize
n += self.lengthString(len(self.data_))

返回对象，而不是字符串。您不能将此对象直接写入文件对象。 在第142行尝试。梦砍废么
