Python网络请求模块urllib与requests使用介绍

import urllib
from urllib.request import request
from urllib.urlopen import urlopen
# import urllib2
import requests
# 使用 urllib 方式获取
response = urllib.request.urlopen('http://www.baidu.com')
# read() 读取的是服务器的原始返回数据 decode() 后会进行转码
print(response.read().decode())
# 使用 requests 方式获取
# request 模块相比
resp = requests.get('http://www.baidu.com')
print(resp)
print(resp.text)

req = urllib.request.Request('http://www.baidu.com')
with urllib.request.urlopen(req) as response:
print(response.read())

req = urllib.request.Request('http://www.baidu.com')
req.add_header('User-Agent', 'Mozilla/6.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/8.0 Mobile/10A5376e Safari/8536.25')
with urllib.request.urlopen(req) as response:
print(response.read())

# 使用带参数的接口访问
tencent_api = "http://qt.gtimg.cn/q=sh601939"
response = urllib.request.urlopen(tencent_api)
# read() 读取的是服务器的原始返回数据 decode() 后会进行转码
print(response.read())
resp = requests.get(tencent_api)
print(resp)
print(resp.text)
