大家看一下这个程序有没有大的错误?就是哪里写得不对
下面是原文
Creating a folder
To create a folder, send an HTTP POST request with an <atom:entry> containing a category element with http://schemas.google.com/g/2005#kind scheme and http://schemas.google.com/docs/2007#folder term. The folder name will be determined by the value of the atom:title element if present. If no atom:title element is submitted, a default name will be chosen.
Here is an example of creating a folder which will be called Example Folder on Google Documents.
POST /feeds/default/private/full HTTP/1.1
Host: docs.google.com
GData-Version: 3.0
Authorization: <your authorization header here>
Content-Length: 245
Content-Type: application/atom+xml
<?xml version='1.0' encoding='UTF-8'?>
<entry xmlns="http://www.w3.org/2005/Atom">
<category scheme="http://schemas.google.com/g/2005#kind"
term="http://schemas.google.com/docs/2007#folder"/>
<title>Example Folder</title>
</entry>If the request is successful, a 201 Created response will be returned along with a <atom:entry> describing the folder on the server.
