更新批量联系人时，如果匹配或If-None-Match标头或条目etag属性需要错误

Question

哪些步骤会重现此问题？

1.使用批量联系api（gdata-python-client）的更新联系方式如下所示

request_feed = gdata.contacts.data.ContactsFeed()
contact_entry = gd_client.GetContact(contact_url)
request_feed.AddUpdate(entry=contact_entry, batch_id_string='update')
response_feed = gd_client.ExecuteBatch(request_feed,'https://www.google.com/m8/feeds/contacts/default/full/batch')
for entry in response_feed.entry:
  print '%s: %s (%s)' % (entry.batch_id.text, entry.batch_status.code, entry.batch_status.reason)

2。试图在文档

中添加If-match标头来请求

 ifmatch_header = atom.client.CustomHeaders(**{"If-Match": "*"})
 response_feed = gd_client.ExecuteBatch(request_feed,'https://www.google.com/m8/feeds/contacts/default/full/batch', ifmatch_header=ifmatch_header)

预期产量是多少？你怎么看？

我收到 If-Match或If-None-Match标题或条目etag属性
