python机械化文件上传UnicodeDecode错误

Question

So I have a little script that I would like to use to upload some PDFs to my citation-site-of-choice (citeulike.org)

Thing is its not working. It does this:

 so want to upload /Users/willwade/Dropbox/Papers/price_promoting_643127.pdf to 12589610 Traceback (most recent call last): File "citeuupload.py", line 167, in <module> cureader.parseUserBibTex() File "citeuupload.py", line 160, in parseUserBibTex self.uploadFileToCitation(b['citeulike-article-id'],self.localpapers+fileorfalse) File "citeuupload.py", line 138, in uploadFileToCitation resp = self.browser.submit() File "build/bdist.macosx-10.8-intel/egg/mechanize/_mechanize.py", line 541, in submit File "build/bdist.macosx-10.8-intel/egg/mechanize/_mechanize.py", line 203, in open File "build/bdist.macosx-10.8-intel/egg/mechanize/_mechanize.py", line 230, in _mech_open File "build/bdist.macosx-10.8-intel/egg/mechanize/_opener.py", line 193, in open File "build/bdist.macosx-10.8-intel/egg/mechanize/_urllib2_fork.py", line 344, in _open File "build/bdist.macosx-10.8-intel/egg/mechanize/_urllib2_fork.py", line 332, in _call_chain File "build/bdist.macosx-10.8-intel/egg/mechanize/_urllib2_fork.py", line 1142, in http_open File "build/bdist.macosx-10.8-intel/egg/mechanize/_urllib2_fork.py", line 1115, in do_open File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 955, in request self._send_request(method, url, body, headers) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 989, in _send_request self.endheaders(body) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 951, in endheaders self._send_output(message_body) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 809, in _send_output msg += message_body UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 544: ordinal not in range(128) 

and the code:

 def uploadFileToCitation(self,artid,file): print 'so want to upload', file, ' to ', artid self.browser.open('http://www.citeulike.org/user/'+cUser+'/article/'+artid) self.browser.select_form(name="fileupload_frm") self.browser.form.add_file(open(file, 'rb'), 'application/pdf', file, name='file') try: resp = self.browser.submit() self.wait_for_api_limit() except mechanize.HTTPError, e: print 'error' print e.getcode() print resp.read() exit() 

NB: I can see it's reading in the file correctly (and it does exist). Also note that I'm doing this elsewhere

  self.browser = mechanize.Browser() self.browser.set_handle_robots(False) self.browser.addheaders = [ ("User-agent", 'me@me.com citeusyncpy/1.0'), ] 

Full code is here

Try to check this similar question .

To clarify, the message is constructed in httplib from the method, URL, headers, etc. If any of these is Unicode, the whole string gets converted to Unicode (I presume this is normal Python behavior). Then if you try to append a UTF-8 string you get the error I described in the original question...

From looks of it's a problem with encoding that proper header can fix.

Also you can check this issue .
