hi,
sending a simple post request with a body (cookies) results in a error
here.
im using python 3.x with the latest twisted and treq installed via pip
in a virtualenv.
the code gets a chatroom login page, extracts two values, gets the
cookies and logs a user into the chat. (incomplete)
thing is for being logged in i need to send my current phpsessionid in
the post request...
glyph (without seeing the the code or backtrace) suggested that:
"I think the issue might be that it doesn't support bytes() on py3,
it's registered against str() or something"
here is my code:
from myhttp import getLoginPage, login
from twisted.internet import reactor
def myPrint(result):
print("result:", result)
def myError(failure):
print("failure:", failure)
def lala():
#d = getLoginPage()
d = login()
d.addCallback(myPrint)
d.addErrback(myError)
if __name__ == '__main__':
lala()
reactor.run()
from myhttp import getLoginPage, login
from twisted.internet import reactor
def myPrint(result):
print("result:", result)
def myError(failure):
print("failure:", failure)
def lala():
#d = getLoginPage()
d = login()
d.addCallback(myPrint)
d.addErrback(myError)
if __name__ == '__main__':
lala()
reactor.run()
