python爬虫之 Requests库的基本使用

注：requests不是python内置的库，需要单独安装，pip3 install requests

功能详解:

基本GET请求:

import requests

response = requests.get(‘http://httpbin.org/get‘)
print(response.text)

基本POST请求:

post请求需要添加一个data参数，该参数是由字典构造

import requests

data= {
    ‘name‘:‘miu‘,
    ‘age‘:24
}
response = requests.post(‘http://httpbin.org/post‘,data=data)
print(response.text)

响应：

import requests

response = requests.get("http://www.baidu.com")
print(type(response.status_code),response.status_code)
print(type(response.headers),response.headers)
print(type(response.cookies),response.cookies)
print(type(response.url),response.url)
print(type(response.history),response.history)
