How do you send an HTTP Get Web Request in Python?

I am having trouble sending data to a website and getting a response in Python. I have seen similar questions, but none of them seem to accomplish what I am aiming for.

This is my C# code I'm trying to port to Python:

    static void Request(Uri selectedUri)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(selectedUri);
request.ServicePoint.BindIPEndPointDelegate = BindIPEndPointCallback;
request.Method = "GET";
request.Timeout = (int)Timeout.TotalMilliseconds;
request.ReadWriteTimeout = (int)Timeout.TotalMilliseconds;
request.CachePolicy = CachePolicy;
request.UserAgent = UserAgent;


using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
using (StreamReader responseReader = new StreamReader(response.GetResponseStream()))
{
string responseText = responseReader.ReadToEnd();
File.WriteAllText(UrlFileName, responseText.Trim(), Encoding.ASCII);
}
}
}

Here is my attempt in Python:

def request():
web = httplib.HTTPConnection('https://someurl.com');
headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}
web.request("GET", "/heartbeat.jsp", headers);
response = web.getresponse();
stream = ""; #something is wrong here

Any help would be appreciated!

In Python, you can use urllib2 (http://docs.python.org/2/library/urllib2.html) to do all of that work for you.

Simply enough:

import urllib2
f =  urllib2.urlopen(url)
print f.read()

Will print the received HTTP response.

To pass GET/POST parameters the urllib.urlencode() function can be used. For more information, you can refer to the Official Urllib2 Tutorial

You can use urllib2

import urllib2
content = urllib2.urlopen(some_url).read()
print content

Also you can use httplib

import httplib
conn = httplib.HTTPConnection("www.python.org")
conn.request("HEAD","/index.html")
res = conn.getresponse()
print res.status, res.reason
# Result:
200 OK

or the requests library

import requests
r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
r.status_code
# Result:
200
