python2与python3爬虫中get与post对比解析
作者:kolane
这篇文章主要介绍了python2与python3爬虫中get与post对比解析,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
python2中的urllib2改为python3中的urllib.request
四种方式对比:
python2的get
# coding=utf-8 import urllib import urllib2 word = urllib.urlencode({"wd":"百度"}) url = 'http://www.baidu.com/s' + '?' + word request = urllib2.Request(url) print urllib2.urlopen(request).read().decode('utf-8')
python3的get
import urllib.request import urllib.parse data = urllib.parse.urlencode({'wd':'百度'}) url = 'http://wwww.baidu.com/s?' + data # url = 'http://www.baidu.com/s?wd=' + urllib.parse.quote('百度') response = urllib.request.urlopen(url) print (response.read().decode('utf-8'))
python2的post
# coding=utf-8 import urllib import urllib2 formdata = { 'name':'百度' } data = urllib.urlencode(formdata) request = urllib2.Request(url = "http://httpbin.org/post", data=data) response = urllib2.urlopen(request) print response.read()
python3的post
import urllib.parse import urllib.request data = bytes(urllib.parse.urlencode({'name':'百度'}),encoding='utf8') response = urllib.request.urlopen('http://httpbin.org/post',data=data) print(response.read().decode('utf-8'))
或
import urllib.parse import urllib.request request = urllib.request.Request('http://httpbin.org/post',data=bytes(urllib.parse.urlencode({'name':'百度'}),encoding='utf8))')) response = urllib.request.urlopen(request) print (response.read().decode('utf-8'))
