如何在urllib2请求中发送utf8内容?

在过去的半天里,我一直在思考下面的问题,虽然我发现了一些关于类似问题的信息,但没有什么是真正正确的。在

我试图使用urllib2发送一个PUT请求,其中包含一些Unicode字符的数据:

body = u'{ "bbb" : "asdf\xd7\xa9\xd7\x93\xd7\x92"}'
conn = urllib2.Request(request_url, body, headers)
conn.get_method = lambda: 'PUT'
response = urllib2.urlopen(conn)

我尝试过使用body = body.encode('utf-8')和其他变体,但是无论我做什么,都会出现以下错误:

^{pr2}$

具有以下调用堆栈之一:

File "..." in ...
  195.         response = urllib2.urlopen(conn)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in urlopen
  126.     return _opener.open(url, data, timeout)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in open
  394.         response = self._open(req, data)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in _open
  412.                                   '_open', req)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in _call_chain
  372.             result = func(*args)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in http_open
  1199.         return self.do_open(httplib.HTTPConnection, req)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in do_open
  1168.             h.request(req.get_method(), req.get_selector(), req.data, headers)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py" in request
  955.         self._send_request(method, url, body, headers)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py" in _send_request
  989.         self.endheaders(body)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py" in endheaders
  951.         self._send_output(message_body)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py" in _send_output
  815.             self.send(message_body)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py" in send
  787.             self.sock.sendall(data)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py" in meth
  224.     return getattr(self._sock,name)(*args)

或下面的调用堆栈(用于我执行body = body.encode('utf-8')时):

File "..." in ...
  195.         response = urllib2.urlopen(conn)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in urlopen
  126.     return _opener.open(url, data, timeout)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in open
  394.         response = self._open(req, data)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in _open
  412.                                   '_open', req)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in _call_chain
  372.             result = func(*args)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in http_open
  1199.         return self.do_open(httplib.HTTPConnection, req)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py" in do_open
  1168.             h.request(req.get_method(), req.get_selector(), req.data, headers)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py" in request
  955.         self._send_request(method, url, body, headers)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py" in _send_request
  989.         self.endheaders(body)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py" in endheaders
  951.         self._send_output(message_body)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py" in _send_output
  809.             msg += message_body

我做错什么了?如何通过urllib2发送带有Unicode字符的正文?如果没有Unicode字符,一切正常。在

还要注意,my Content-Type头被设置为application/json;charset=utf-8。在

如果它在任何方面相关,我所做的上下文是这样的:我收到一个请求到我的Django服务器,然后将请求委托给另一个Django服务器。我不重定向,只是从我自己的服务器发送请求得到响应并将其发送回。所以body是Django视图中的request.body。在
