So I'm trying to send a file through webpy and urllib2 but I can't get
around these UnicodeErrors. Here's the code:
# controller
x = web.input(video_original={})
params = {'foo': x['foo']}
files = (('video[original]', 'test', x['video_original'].file.read
()),)
client.upload(upload_url, params, files, access_token())
# client library
def __encodeMultipart(self, fields, files):
"""
fields is a sequence of (name, value) elements for regular
form fields.
files is a sequence of (name, filename, value) elements for
data to be uploaded as files
Return (content_type, body) ready for httplib.HTTP instance
"""
boundary = mimetools.choose_boundary()
crlf = '\r\n'
l = []
for k, v in fields.iteritems():
l.append('--' + boundary)
l.append('Content-Disposition: form-data; name="%s"' % k)
l.append('')
l.append(v)
for (k, f, v) in files:
l.append('--' + boundary)
l.append('Content-Disposition: form-data; name="%s";
filename="%s"' % (k, f))
l.append('Content-Type: %s' % self.__getContentType(f))
l.append('')
l.append(v)
l.append('--' + boundary + '--')
l.append('')
body = crlf.join(l)
return boundary, body
def __getContentType(self, filename):
return mimetypes.guess_type(filename)[0] or 'application/octet-
stream'
def upload(self, path, post_params, files, token=None):
if token:
token = oauth.OAuthToken.from_string(token)
url = "http://%s%s"; % (self.authority, path)
(boundary, body) = self.__encodeMultipart(post_params, files)
headers = {'Content-Type': 'multipart/form-data; boundary=%s' %
boundary,
'Content-Length': str(len(body))
}
request = oauth.OAuthRequest.from_consumer_and_token(
self.consumer,
token,
http_method='POST',
http_url=url,
parameters=post_params
)
request.sign_request(oauth.OAuthSignatureMethod_HMAC_SHA1(),
self.consumer, token)
request = urllib2.Request(request.http_url, postdata=body,
headers=headers)
request.get_method = lambda: 'POST'
return urllib2.urlopen(request)
Unfortunately I get two kinds of unicode error, the first one in the
crlf.join(l):
Traceback (most recent call last):

111, in __encodeMultipart
body = crlf.join(l)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xb7 in position

And here's another one:

File "/Users/oscar/projects/work/whitelabel/oauth_client.py", line
111, in __encodeMultipart
body = crlf.join(l)

Does anyone know why this errors happens and what I should do to
prevent them? Many thanks.
