This article example describes the basic usage of Python Requests library. Shared for your reference, as follows:
requests is an http client library for python, providing a set of concise API for developers to use. Here is a brief introduction to its installation and use. Here is the official documentation.
0 Installation
pip install requests
1 Send request
r=('')
print r.status_code,
r=('/post')
r=('/put')
r=('/delete')
r=('/head')
r=('/')
2 Send get parameter
param={'key1':value1,'key2':value2}
r=('/',params=param)
3 Send post parameters
param={'key1':value1,'key2':value2}
r=('/',params=param) #Format
r=('/',json=param) #json format data
file= {'file':open('','rb')}
r=('/post',files=file)
4 File downloads
with open('','wb') as pic:
for chunk in response.iter_content(size):
(chunk)
5 Carrying the header
header={'key1':value1,'key2':value2}
r=('/',headers=header)
6 Carrying cookies
cookie={'key1':value1,'key2':value2}
r=('/',cookies=cookie)
7 Redirection
By default requests are allowed to redirect, and the history of redirects is saved in thearray
If redirection is not needed, it can be turned off with the switch
r=('/',allow_redirects=False)
8 Using proxies
Using the socks proxy requires the installation of a three-way extension package
pip install requests[socks]
proxy={
'http':'http://127.0.0.1:8000',
'https':'https://127.0.0.1:8080'
'http':'socks5://user:[email protected]:8132'
}
r=('/',proxies=proxy)
9 Setting the Connection Timeout
r=('/',timeout=2.5)
10 ssl certificate
Certificate Validation
('', verify=True)
('', cert=('/path/', '/path/key'))
If you specify a local certificate and key, the key needs to be decrypted.
11 requests object
12 Response object
Corresponding request object socketData obtained directly from the Text data decoded from response headers No decoding, returns binary data() Decode the returned data in json Dictionary form to store returned headers Dictionary form to store returned cookies
