Several ways that Python calls API interfaces

I believe that the students who have done the automation operation have used API interface to accomplish certain actions. API is a set of mature system necessary interface, can be called by other systems or scripts, which is also a compulsory operation of automation.

This article introduces several ways to invoke the API in Python, and here are the libraries that will be used in Python.

-Urllib2

-Httplib2

-Pycurl

-Requests

1. Urllib2

Import urllib2, Urllibgithub_url = ' https://api.github.com/user/repos ' Password_manager = urllib2. Httppasswordmgrwithdefaultrealm () Password_manager.add_password (None, Github_url, ' user ', ' * * * ') auth = urllib2. Httpbasicauthhandler (Password_manager) # Create an authentication Handleropener = Urllib2.build_opener (auth) # Create an Opener with the authentication Handlerurllib2.install_opener (opener) # Install the opener ... request = Urllib2. Request (Github_url, Urllib.urlencode ({' name ': ' Test repo ', ' description ': ' Some Test Repository '}) # Manual encoding Requiredhandler = Urllib2.urlopen (Request) print handler.read ()

2. Httplib2

Import urllib, Httplib2github_url = ' H = httplib2. Http (". Cache") h.add_credentials ("User", "******", "data = Urllib.urlencode ({" Name ":" Test "}) resp, content = H.request ( Github_url, "POST", data) print content

3. Pycurl

Import Pycurl, Jsongithub_url = "User_pwd =" user:***** "data = Json.dumps ({" Name ":" Test_repo "," description ":" Some test Repo "}) c = Pycurl. Curl () c.setopt (Pycurl. URL, Github_url) c.setopt (Pycurl. Userpwd, User_pwd) c.setopt (Pycurl. POST, 1) c.setopt (Pycurl. Postfields, data) C.perform ()

4. Requests

Import requests, Jsongithub_url = "data = Json.dumps ({' name ': ' Test ', ' description ': ' Some Test Repo '}) R = Requests.post (gi Thub_url, data, auth= (' user ', ' * * * * ')) print R.json

There are several ways to invoke the API to perform the action, but requests is the simplest, clearest, and recommended way to use this code.
