HTTPError... read the response body?
Hi There,
I am trying to connect to a web service but I am getting HTTP 400, I
am not too concerned about the HTTP error - but what I'd like to know
if there is anyway I can read the response body in the HTTP 400 or 500
case? Does the HTTPError allow this? or the urllib2 in anyway?
This is what I have at the moment...
import sys, urllib2
import socket
class APIConnector:
def connect(*args):
length = len(args[2])
headers = {"Content-Length": length, "Content-Type":
"text/xml", "SOAPAction": "\"http://some.api.com/RemovedAction\""}
try:
#url, body, headers
rq = urllib2.Request(args[1], args[3],
headers)
rs = urllib2.urlopen(rq)
print rs.read()
except urllib2.HTTPError, e:
conn = e
print 'error', conn.code, 'message: ',
conn.msg, 'filename: ', conn.filename, 'headers: ', conn.hdrs, 'body:
', conn.read()
I thought that conn.read() may show the body, but it seems not... Can
anyone help please, or suggest another way around? I am using python
2.5 installed with MAC OS X Leopard.
Cheers
Stu

All I'd like to know if there is anyway to read the body of an HTTP Error, so for instance, if I were to recieve a 404 - I'd like to see the content that the server returns with a 404 error. -- http://mail.python.org/mailman/listinfo/python-list
How to create a virtual serial port?
Hi, I am trying to work out if its possible, to create a virtual serial port with Python? Would anyone know how to go about this in code? Any help would be greatly appreciated! :) I have a had a google and the topics returned only seem to reflect "reading" serial port data, particularly pySerial results...

I'm on a OS X, python 2.5. Basically I will have a remote application pushing data (GPS) over the network to a python application I have running on my Mac, I want this python application to again push the data on to a "virtual serial port". Then the GPS program I have running on my MAC, RouteBuddy, can read the data from that serial port as standard. The only part I am concerned about here though, is if I can create a serial port virtually and push data out of it? Hope that defines a little more clarity for yourself. -- http://mail.python.org/mailman/listinfo/python-list

Scott, many thanks for the advice. Will try to find a more specific forum of conversation. Stu -- http://mail.python.org/mailman/listinfo/python-list

I didn't realise people were still posting on this thread and have spent the last 3 hours trying to get some example code to create a pseudo TTY (pty) in Python, I get that I have to use the pty module, but finding an example is like searching for... lets go festing ...an easter egg in a forest ;) You wouldn't have any pointers to initiating a PTY and how to write to it? This is all I want to achieve. My point in all this is actually that I ordered a USB GPS Receiver and it wont arrive for another two weeks, being my impatient self, I am writing an app for my iPhone to broadcast its GPS location over the network to my laptop. I then want to get this data into the NMEA format and push this data onto a PTY - this will in-effect replace the USB GPS Receiver and the GPS software can read it :) Cheers Stu -- http://mail.python.org/mailman/listinfo/python-list
