直接将数据放入AppEngine的Blobstore中

问题描述

AppEngine的标准API假定文件是从HTML表单上传的。
我试图从一个可以由非Html客户端（Flash，iPhone等）调用的REST API方法将文件发布到blobstore。

我尝试工作的代码：

 ＃获取blobstore上传url 
 upload_url = blobstore。 create_upload_url（ /活动/ upload_finished）; 
 
＃同步调用blobstore url来发布我们的图片
 result = urlfetch.fetch（url = upload_url，
 payload = request.FILES，
 method = urlfetch.POST，
 headers = {'Content-Type'：'multipart / form-data'}）
  

我收到以下错误：

解决方案

App Engine（版本1.4.3）允许您直接将数据写入Blobstore

您不再需要使用上传url方法。

The AppEngine's standard API assumes files are uploaded from an HTML form.I'm trying to post a file to the blobstore from a REST API method that can be called by a non Html client (Flash, iPhone, etc.)

The code I'm trying to get working:

# Get the blobstore upload url    
upload_url = blobstore.create_upload_url("/activities/upload_finished");

# Make sync call to the blobstore url to post our image
result = urlfetch.fetch(url=upload_url,
                        payload=request.FILES,
                        method=urlfetch.POST,
                        headers={'Content-Type': 'multipart/form-data'})

I'm getting the following error:

Any idea?
Has anyone tried posting to the blobstore not through a web form?

解决方案

App Engine (version 1.4.3) allows you to directly write data to the blobstore.
You no longer need to use the upload url method.
