python Requests模块的使用简介

Requests的安装：

pip install Requests

Requests的使用：

import requests

url = "http://www.mzitu.com"

response = requests.get(url)  # 获得请求

response.encoding = "utf-8"  # 改变其编码

html = response.text  # 获得网页内容

binary__content = response.content  # 获得二进制数据

raw = requests.get(url, stream=True)  # 获得原始响应内容

headers = {‘user-agent‘: ‘my-app/0.0.1‘}  # 定制请求头
r = requests.get(url, headers=headers)

cookies = {"cookie": "# your cookie"}  # cookie的使用
r = requests.get(url, cookies=cookies)

# 后续

tips:

raw = requests.get(url, stream=True)  # 将文本流保存到文件
filename = ‘example.jpg‘
with open(filename, ‘wb‘) as fd:
    for chunk in raw.iter_content():
        fd.write(chunk)
    fd.close()
