Sample code for Python interface test automation

This article focuses on "sample code for Python interface test automation". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn the sample code of Python interface test automation.

1. API request

Python, especially the urllib and requests modules in python 3.x, are the two main modules used to request url. In these two modules, if it is only a url request that supports http protocol, it is recommended to use requests module. Why do you say that? Because Einstein said: simplicity is beauty. The requests module encapsulates the urllib module again, which makes it more convenient to use. The module supports GET, POST, PUT, DELETE and other request methods. The request return information includes the status code and the message body, which is represented by three digits, and the message body can be expressed in string, binary or json format. Let's use an example to introduce the use of the requests module. The code is as follows:

Import requests def get_method (url, para, headers): try: req = requests.get (url=url, params=para, headers=headers) except Exception as e: print (e) else: if req.status_code = = "200": return req else: print ("Requests Failed.") If _ name__=='__main__': url= "http://www.google.com" req = get_method (url=url, para=None, headers=None) print (req.status_code) print (req.text)

The output is:
