尝试将图像文件上传到集合时出现400错误

Question

我想写一个脚本将我的照片上传到Google云端硬盘。经过几个小时的挖掘Google文档列表API。我选择gdata-python-client 2.0.17（最新版）来构建我的脚本。一切运作良好，除了我不能上传文件到一个集合。这是例外。

 
Traceback (most recent call last): 
    File "./upload.py", line 27, in 
    upload(sys.argv[1]) 
    File "./upload.py", line 22, in upload 
    client.create_resource(p, collection=f, media=ms) 
    File "/usr/local/lib/python2.7/dist-packages/gdata/docs/client.py", line 300, in create_resource 
    return uploader.upload_file(create_uri, entry, **kwargs) 
    File "/usr/local/lib/python2.7/dist-packages/gdata/client.py", line 1090, in upload_file 
    start_byte, self.file_handle.read(self.chunk_size)) 
    File "/usr/local/lib/python2.7/dist-packages/gdata/client.py", line 1048, in upload_chunk 
    raise error 
gdata.client.RequestError: Server responded with: 400, <errors xmlns='http://schemas.google.com/g/2005'><error><domain>GData</domain><code>InvalidEntryException</code><internalReason>We're sorry, a server error occurred. Please try again.</internalReason></error></errors> 

在对gdata的源代码进行黑客入侵之后，我打印了一些调试信息。

PUT文件的最后部分引发异常。

我会建议你去尝试新的谷歌云端硬盘API V2，使得它更与媒体上传更好的支持更容易：https://developers.google.com/drive/v2/reference/files/insert

一旦你得到一个authorized service instance，你可以简单地插入一个新的文件，像这样：

from apiclient import errors 
from apiclient.http import MediaFileUpload 
# ... 

def insert_file(service, title, description, parent_id, mime_type, filename): 
    """Insert new file. 

    Args: 
    service: Drive API service instance. 
    title: Title of the file to insert, including the extension. 
    description: Description of the file to insert. 
    parent_id: Parent folder's ID. 
    mime_type: MIME type of the file to insert. 
    filename: Filename of the file to insert. 
    Returns: 
    Inserted file metadata if successful, None otherwise. 
    """ 
    media_body = MediaFileUpload(filename, mimetype=mime_type, resumable=True) 
    body = { 
    'title': title, 
    'description': description, 
    'mimeType': mime_type 
    } 
    # Set the parent folder. 
    if parent_id: 
    body['parents'] = [{'id': parent_id}] 

    try: 
    file = service.files().insert(
     body=body, 
     media_body=media_body).execute() 

    return file 
    except errors.HttpError, error: 
    print 'An error occured: %s' % error 
    return None
