urllibopen

 

基本库区别

 

直接使用urllibopen无法构建复杂的header信息，需要借助Request

from urllib import request,parse # # url = 'http://httpbin.org/post' # headers = {
  # "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.36", # "Host":"httpbin.org" # } # dict = {
  # 'name':'Germey' # } # data = bytes(parse.urlencode(dict), encoding='utf-8') # req = request.Request(url=url, data=data, headers=headers, method='POST') # response = request.urlopen(req) # print(response.read().decode('utf-8')) # 还可以add_headers方法 url = 'http://httpbin.org/post' dict = {
  'name':'Germey' } data = bytes(parse.urlencode(dict), encoding='utf-8') req = request.Request(url=url, data=data, method='POST') req.add_header("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.36") response = request.urlopen(req) print(response.read().decode('utf-8')) 基本库使用起来比较麻烦，添加请求头，请求数据，设置代理设置cookie等等都比较麻烦，因此使用Request库比较好 安装 pip3 install request
