Python uses requests to simulate http requests and request headers

First, send the request through requests

Previously, we have been using urllib and urllib2 to simulate the sending of http requests. In real scenarios, we need to create self-defined header, body, and so on. It is very troublesome to use urllib. By chance, when we come into contact with requests, we can send xml, easy to use, and directly add code:

Requests connected (): # pass in url and request parameters through formal parameters. Get method sends request (param): get = requests.get (= = param) # closes connection get.close () # returns response get.text # passes url through formal parameters, test data, request header Post method to send a request (dataheader): post = requests.post (= data=header) # close the connection post.close () # return respone post.text

Get the session, insert the session into the header and send it to the server

From com.utils.ConnUrl import ConnUrlimport requestsclass getheader (): @ staticmethod def session (): # encapsulate test data data= 'test data' url = ConnUrl.getUrl () url = url+'200000' # set header header = {' content-type':'application/octet-stream'} # post request post = requests.post (url, data=data, headers=header) # return data through split function cutting Get session jsessionid = post.headers ['Set-Cookie'] .split (' ') [0] return jsessionid
