python - How to send utf-8 content in a urllib2 request? -

i'm struggling following question past half day , although i've found info similar problems, nothing hits spot.

i'm trying send put request using urllib2 data contains unicode characters:

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) 

i've tried use body = body.encode('utf-8') , other variations, whatever following error:

unicodeencodeerror @ ... 'ascii' codec can't decode byte 0xc3 in position 15: ordinal not in range(128) 

with 1 of following call stacks:

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) 

or following call stack (for when body = body.encode('utf-8')):

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 

what doing wrong? how can send body unicode characters via urllib2? if there no unicode characters, works fine.

also note content-type header set application/json;charset=utf-8.

if it's relevant in way, context of i'm doing this: i'm getting request django server, , delegate request django server. don't redirect, send request own server response , send back. body request.body in django view.

edit:

my headers are:

{ 'origin': 'http://10.0.0.146:8000',  'accept-language': 'en-us,en;q=0.8',  'accept-encoding': 'gzip,deflate,sdch',  'host': 'localhost:5000',  'accept': 'application/json, text/plain, */*',  'user-agent': 'mozilla/5.0 (macintosh; intel mac os x 10_8_3) applewebkit/537.31 (khtml, gecko) chrome/26.0.1410.65 safari/537.31',  'accept-charset': 'iso-8859-1,utf-8;q=0.7,*;q=0.3',  'connection': 'keep-alive',  'x-requested-with': 'xmlhttprequest',  'pragma': 'no-cache',  'cache-control': 'no-cache',  'referer': 'http://localhost:5000/',  'content-type': 'application/json;charset=utf-8',  'authorization': 'apikey ogklpgsesnytogidbsldhjjvyvjcbg:0d5897b5204c2f2527f532c6a97ba18a7f06acdc',  'cookie': 'username=ogklpgsesnytogidbsldhjjvyvjcbg; _we_wk_ls_=%7b%22time%22%3a1369123506709%7d; __jwpusr=39e63770-ec5c-4b96-9f7f-b199703d0d36; sessionid=0d741a7560258b301979a1c853b42a81; api_key=0d5897b5204c2f2527f532c6a97ba18a7f06acdc' } 

you need pass byte strings request. applies headers, url , body.

if of 3 inputs contain unicode values, automatic conversions between unicode , strings take place when concatenating, invariably lead grief.
