Re: Need help to figure out urllib2.Request()

Hi folks,

I tried to open some web pages with urllib2.Request(url, data, headers), but
it always give me a 404 error.
Eg.
url = 'http://www.whatever.com/somephp.php'
data = {}
data['id'] = account
for i in book2Open:
data['book'] = i
url_data = urllib.urlencode(data)
request = urllib2.Request(url, url_data, headers)
response = urllib2.urlopen(request)
html = response.read()
==> HTTPError: HTTP Error 404: Not Found


However, the page is retrievable when I manually put url and data together.
Eg.
url = 'http://www.whatever.com/somephp.php'
data = {}
data['id'] = account
for i in book2Open:
data['book'] = i
url_data = urllib.urlencode(data)
full_url = url + '?' + url_data
request = urllib2.Request(full_url, "", headers)
response = urllib2.urlopen(request)
html = response.read()
==> works fine

Any idea ?

The first example uses HTTP POST method; the second HTTP GET.
See http://docs.python.org/lib/module-urllib2.html

    ... In PHP that would throw some nasty HTTP-related warnings and potentially break the page as you are changing the headers after HTML display? ... You are writing code in a special format that is compiled in to a servlet, which is then executed by the server when the page is requested. ... The other thing is that writing things "after HTML display" is probably very difficult as the display is done on the users computer when they have recieved the response. ... When you create a response for the user it does not necessarily get sent back as soon as you start, and more importantly the headers do not necessarily finish as soon as you start writing to the body. ...

    ... I suppose you could filter based on e-mail addresses in the To or Cc headers but those headers are *data* that the sender put into the message and which were sent during the DATA command from the e-mail client to the SMTP server. ... So your account may not be included in any e-mail addresses listed in the To or Cc headers, if any e-mail addresses are even listed. ... It still came *through* your ISP e-mail account whether or not it had the OPTIONAL To and Cc headers. ...
