Summary of how python sends HTTP requests

This example describes how to send an HTTP request using python. Share it with you for your reference. The details are as follows:

Here, Python uses the GET/HEAD/POST method for HTTP requests.

1. GET method:

>>> import httplib >>> conn = httplib.HTTPConnection("www.python.org") >>> conn.request("GET", "/index.html") >>> r1 = conn.getresponse() >>> print r1.status, r1.reason 200 OK >>> data1 = r1.read() >>> conn.request("GET", "/parrot.spam") >>> r2 = conn.getresponse() >>> print r2.status, r2.reason 404 Not Found >>> data2 = r2.read() >>> conn.close()

2. HEAD method:

>>> import httplib >>> conn = httplib.HTTPConnection("www.python.org") >>> conn.request("HEAD","/index.html") >>> res = conn.getresponse() >>> print res.status, res.reason 200 OK >>> data = res.read() >>> print len(data) 0>>> data == '' True

3. POST method:

>>> import httplib, urllib >>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0}) >>> headers = {"Content-type": "application/x-www-form-urlencoded", ...      "Accept": "text/plain"} >>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80") >>> conn.request("POST", "/cgi-bin/query", params, headers) >>> response = conn.getresponse() >>> print response.status, response.reason 200 OK >>> data = response.read() >>> conn.close()
