Python Interface Test (iii)

Four: Python http of the interface Request

The power of Python is that it provides a lot of standard libraries and third libraries, and this article introduces Urllib

and the third library of requests.

Urllib defines a number of functions and classes that can help us get URL content in complex situations. Complex situations-basic and in-depth verification, redirection, cookies, etc.

The GET request code for Urllib is as follows:

Import urllib.requesturl= ' http://www.baidu.com ' response=urllib.request.request (url=url) html= Urllib.request.urlopen (response) print (Html.getcode ()) print (html.headers)

Request Result:

Urllib POST request, code:

Import urllib.requestimport urllib.parseurl= ' Http://www.tuling123.com/openapi/api ' data={"key": "Your", "info": ' Hello ' }data=urllib.parse.urlencode (data) encode (' Utf-8 ') re=urllib.request.request (url,data) html= Urllib.request.urlopen (re) print (Html.getcode (), html.msg) print (Html.read ())

The following describes the HTTP requests for the requests library,

The above is a case of sending get and post requests using urllib and requests.
