HTTP request Method Library rollup in Python

Recently in the use of Python interface testing, found Python in the HTTP request method There are many kinds of, today take some time to organize the relevant content, to share with you, the specific content is as follows:
One, Python comes with library----URLLIB2

Python comes with a library urllib2 used more, simple to use as follows:

Import Urllib2

Response = Urllib2.urlopen (' http://localhost:8080/jenkins/api/json?pretty=true ')

Print Response.read ()

A simple GET request

Import Urllib2

Import Urllib

Post_data = Urllib.urlencode ({})

Response = Urllib2.urlopen (' http://localhost:8080/, Post_data)

Print Response.read ()

Print Response.getheaders ()

This is the simplest urllib2 send post example. More code
Ii. python comes with library--httplib

Httplib is a relatively low-level HTTP request module, Urlib is based on httplib encapsulation. Simple to use as follows:
Import Httplib
conn = Httplib. Httpconnection ("www.python.org")
Conn.request ("GET", "/index.html")
R1 = Conn.getresponse ()
Print R1.status, R1.reason
Data1 = R1.read ()
Conn.request ("GET", "/parrot.spam")
r2 = Conn.getresponse ()
Data2 = R2.read ()
Conn.close ()

A simple GET request

Let's look at the POST request again
Import Httplib, Urllib
params = Urllib.urlencode ({' @number ': 12524, ' @type ': ' Issue ', ' @action ': ' Show '})
headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "Text/plain"}
conn = Httplib. Httpconnection ("bugs.python.org")
Conn.request ("POST", "", params, headers)
Response = Conn.getresponse ()
data = Response.read ()
Print data
Conn.close ()


I think it's too complicated. Every time you write, you have to go through the document again, look at the third.
Iii. third-party library--requests

Sending a GET request is super simple:
Print Requests.get (' http://localhost:8080). Text

Just a word, then look at the POST request
Payload = {' Key1 ': ' value1 ', ' key2 ': ' value2 '}
r = Requests.post ("Http://httpbin.org/post", Data=payload)
Print R.text

Also very simple.

Look again if you want to certify:
url = ' http://localhost:8080 '
r = Requests.post (URL, data={}, Auth=httpbasicauth (' admin ', ' admin '))
Print R.status_code
Print R.headers
Print R.reason

Is it much simpler than URLLIB2, and the requests comes with JSON parsing. This is great.

HTTP requests in Python
Import Urllib
params = Urllib.urlencode ({key:value,key:value})
resulthtml = Urllib.urlopen (' [API or URL] ', params)
result = Resulthtml.read ()
Print result
