python2 urllib2 发送post 请求和get 请求
代码如下：

import urllib2
user_agent = ("User-Agent",
          "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.159 Safari/537.36 Edg/92.0.902.84")

def py2_requests(url, param=None):
    req = urllib2.Request(url)
    # 添加请求头
    req.add_header(*user_agent)
    if param:
        resp = urllib2.urlopen(req, json.dumps(param)) # post 请求
         
      	#状态码
      	resp.getcode()
      	# 获取内容
      	resp.read()
        print(req.get_method())
    else:
        resp = urllib2.urlopen(req)  # get 请求
        print(resp.read()) # 获取相应内容
        print(resp.getcode()) # 相应码
        print(req.get_method())
    return res
