Use python testing tool to achieve (a)

This series of tutorials we will use python achieve some simple testing tools as simple as possible for our tools to the command-line based tools.

Python version of this tutorial series is 3.6.3 .

background

In this section we achieve a simple command-line tool get a request to send, used as follows:

python get.py www.v2ex.com/api/nodes/show.json\?name\=python
接口地址: http://www.v2ex.com/api/nodes/show.json?name=python

状态码: 200

    "avatar_large" : "//cdn.v2ex.com/navatar/8613/985e/90_large.png?m=1531131631"
}

The main usage scenario is to quickly access the http api interface to view the status codes, response headers and response content.

Code

For simplicity, we will use requests library. The setup documentation here .

import requests
from sys import argv

USAGE = '''
USAGE:
python get.py https://api.github.com
'''

if len(argv) != 2:
  print(USAGE)
  exit()

script_name, url = argv

if url[:4] != 'http':
  url = 'http://' + url

r = requests.get(url)

print(f"接口地址: {url}\n")
print(f"状态码: {r.status_code}\n")
print(f"Headers:")
for key, value in r.headers.items():
  print(f"{key} : {value}")

print(r.text)

Time for action

Copy the code again, you can not see up and running
Each line of code to add comments, understand the code done
If you need to add the default when sending requests get Content-Type: application/jsonthe headers, how to modify the code
