Python常用模块之requests模块用法分析

本文实例讲述了Python常用模块之requests模块用法。分享给大家供大家参考，具体如下：

一. GET请求

1.访问一个页面

import requests
r=requests.get('http://www.so.com')
print(r.status_code)
print(r.text)

2.带参数

import requests
params = {'a':1,'b':2}
r=requests.get('http://www.so.com', params=params)
print(r.url)

3.返回数据显示

import requests
r = requests.get('https://pullwave.com/pw2/api/acc_query_words?auth_usr=free_vip&src=s0&w1=%E6%8A%96%E9%9F%B3&w2=&date_end=2019-4-6&json=1')
print(r.content)
print(r.text)
print(r.json())
print(r.headers)

4.请求头

import requests
r = requests.get('https://pullwave.com/pw2/api/acc_query_words?auth_usr=free_vip&src=s0&w1=%E6%8A%96%E9%9F%B3&w2=&date_end=2019-4-6&json=1', headers={'User-Agent': 'Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit'})
print(r.content)
print(r.text)
print(r.json())

二.POST请求

1.传参

r = requests.post('http://www.so.com', data={'fdsafdfs': 'fsdsfa', 'fdsfs': 'dfsfs'})

2.传json

params = {'key': 'value'}
r = requests.post(url, json=params)

3.传文件

upload_files = {'file': open('234.txt', 'rb')}
r = requests.post(url, files=upload_files)

4.带cookie

url = 'http://www.so.com'
cs = {'lalala': 'lalala', 'lallala': '23232'}
r = requests.get(url, cookies=cs)

5.超时

r = requests.get(url, timeout=5)
