Make your own active test with Python--self-motivated test on server side (3)-many other HTTP client instances

In the previous article just implemented a very easy HTTP client feature, request also provides keep alive, SSL, multi-file upload, cookie management function, HTTP requests header management and other rich features, just to your browser to implement the function, Requests inside all support.

#!/usr/bin/env python#coding=utf-8import requestsdef login_douban (username, passwd): post_data={' source ': ' Index_ Nav ', ' form_email ': username, ' Form_password ':p asswd} request_headers={"User-agent": "mozilla/5.0 (Windows NT 6.1; rv:30.0) gecko/20100101 firefox/30.0 "} response=requests.post (" Http://www.douban.com/accounts/login ", Data=post_ Data,headers=request_headers) if u "Little Prince" in Response.text:print "Login successful" return response El Se:print "Login failed" Print Response.text return falsedef say_something (Login_cookie): Post_da ta={' ck ': ' YNNL ', ' rev_title ': U ' hair welfare ', ' rev_text ': U ' landlord is the title party ', ' rev_submit ': U ' OK, speak '} response=requests.post ("http:// Www.douban.com/group/beijing/new_topic ", Data=post_data,cookies=login_cookie) if response.url=="/http www.douban.com/group/beijing/": print" post new content successfully "return True Else:print" Po St Content fail "return Falselogin_response=login_douban (Your_uSENAME,YOUR_PASSWD) say_something (login_response.cookies) 

request_headers={"user-agent": "mozilla/5.0 (Windows NT 6.1; rv:30.0) gecko/20100101 firefox/30.0 "}, the purpose of this line is to simulate this request is Firefox sent out, very many sites in order to block the crawler, will be user-agent this field to block, Of course today's large sites should be more advanced means to screen the crawler, assuming not set this user-agent, requests sent to the request, User-agent value is python-requests/2.3.0 cpython/2.7.3 windows/7\r\n.

Say_something This function did not test, just I frequently debugging, watercress to I enter the login verification code, there is a question here, I have a period of time in the debugging.

With respect to cookies, the session manages this piece, assuming that it is within the same function that the request has actively managed the session without the need for additional processing,

Session = requests. Session () session.post ("Http://www.douban.com/accounts/login", Data=post_data,headers=request_headers) Session.post ("Http://www.douban.com/group/beijing/new_topic", Data=post_data)

This makes it possible to post successfully.

See here everyone will think selenium, is not the same as requests? Requests is more adept at testing without UI interfaces, and selenium is better at web testing with UI.
