Python3.6通过自带的urllib通过get或post方法请求url的实例

# coding:utf-8
from urllib import request
from urllib import parse
url = "http://10.1.2.151/ctower-mall-c/sys/login/login.do"
data = {"id":"wdb","pwd":"wdb"}
params="?"
for key in data:
  params = params + key + "=" + data[key] + "&"
print("Get方法参数："+params)
headers = {
  #heard部分直接通过chrome部分request header部分
  'Accept':'application/json, text/plain, */*',
  'Accept-Encoding':'gzip, deflate',
  'Accept-Language':'zh-CN,zh;q=0.8',
  'Connection':'keep-alive',
  'Content-Length':'14', #get方式提交的数据长度，如果是post方式，转成get方式：【id=wdb&pwd=wdb】
  'Content-Type':'application/x-www-form-urlencoded',
  'Referer':'http://10.1.2.151/',
  'User-Agent':'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.23 Mobile Safari/537.36'
}
data = parse.urlencode(data).encode('utf-8')
req = request.Request(url, headers=headers, data=data) #POST方法
#req = request.Request(url+params) # GET方法
page = request.urlopen(req).read()
page = page.decode('utf-8')
print(page)
