Python sends get and POST requests with the Httplib module

In Python, analog HTTP clients send get and post requests, primarily with the functionality of the Httplib module.

1. Python sends a GET request

I built a test environment locally, the test.php content is to output a sentence:

1	echo‘Old friends and old wines are best.‘;

Python sends a GET request code:

123456789101112131415161718192021

#!/usr/bin/env python#coding=utf8import httplibhttpClient = Nonetry:    httpClient = httplib.HTTPConnection(‘localhost‘, 80, timeout=30)    httpClient.request(‘GET‘, ‘/test.php‘)    #response是HTTPResponse对象    response = httpClient.getresponse()    print response.status    print response.reason    print response.read()except Exception, e:    print efinally:    if httpClient:        httpClient.close()

Finally is used in the above code to ensure that httpclient can be closed even when an error occurs. Run this program and output the results on my computer as follows:

2. Python sends a POST request

Modify the test.php content to print out the $_post array:

1	var_dump($_POST);

Python initiates the POST request code:

123456789101112131415161718192021222324

#!/usr/bin/env python#coding=utf8import httplib, urllibhttpClient = Nonetry:    params = urllib.urlencode({‘name‘: ‘tom‘, ‘age‘: 22})    headers = {"Content-type": "application/x-www-form-urlencoded"                    , "Accept": "text/plain"}    httpClient = httplib.HTTPConnection("localhost", 80, timeout=30)    httpClient.request("POST", "/test.php", params, headers)    response = httpClient.getresponse()    print response.status    print response.reason    print response.read()    print response.getheaders() #获取头信息except Exception, e:    print efinally:    if httpClient:        httpClient.close()

Run the code and output the following on my computer:

Friendly tips:

In the HTTP operation, sometimes need to understand some of the HTTP protocol related content, you can go to the list view: http://www.w3.org/Protocols/rfc2616/rfc2616.html
