python2与python3爬虫中get与post对比解析

# coding=utf-8
import urllib
import urllib2
word = urllib.urlencode({"wd":"百度"})
url = 'http://www.baidu.com/s' + '"htmlcode">

import urllib.request
import urllib.parse
data = urllib.parse.urlencode({'wd':'百度'})
url = 'http://wwww.baidu.com/s"htmlcode">

# 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'))
