I've tried to go ahead and took a chance at going around the gdata
library but I'm stuck again. I can't post pictures. I keep getting a
400 Bad request error.
Here is the code:
h = urllib2.urlopen(authurl,urllib.urlencode
({'accountType':'HOSTED_OR_GOOGLE','Email':email,'Passwd':password,'service':'lh2','source':source}))
for line in h.readlines():
if line.startswith('Auth='):
authtoken = line[line.index('=')+1:]
url = 'http://picasaweb.google.com/data/feed/api/user/%s' % (username)
authorization = "GoogleLogin auth=%s" % (authtoken)
if True:
h = httplib.HTTPConnection(host, port)
h.putrequest('PUT', path)
h.putheader('Content-Type', 'image/jpeg')
h.putheader('Content-Length', str(os.path.getsize(fn)))
h.putheader('Slug', 'keep-alive2.jpg')
h.putheader('Authorization', authorization)
h.endheaders()
# Chunked transfer encoding
# Cf. 'All HTTP/1.1 applications MUST be able to receive and
# decode the "chunked" transfer-coding'
# - http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html
f = open(fn,'rb')
bytes = f.read()
h.send(bytes)
resp = h.getresponse()
status = resp.status # an int
I've also recorded the http request:
