Aws s3 service can not be connected on Tokyo region

[luqitao]

1、The domain name of s3 on tokyo region is "s3-ap-northeast-1.amazonaws.com", Pinging it would be successful, but couldn't get s3 object, the returned result is an exception of httplib.BadStatusLine. Here is my test code which run on az31 node:

from adapter import S3Adapter
driver=S3Adapter('my access_key_id','my secret_key',region='ap-northeast-1',secure=False)
s3_object=driver.get_object(container_name='tokyohybridbucket',object_name='2f06844e-3d59-45de-9654-b5f38b891d65')
print s3_object

the result:
error: <class 'httplib.BadStatusLine'>

2、The same code run on our working PC, it would be successful.
the result is like this:
<Object: name=2f06844e-3d59-45de-9654-b5f38b891d65, size=19005440, hash=db3bd8e8a991ee225f3779412fa48775-3, provider=Amazon S3 (ap-northeast-1) ...>

Does anyone have any idea on how to solve this?
