基于Python的Post请求数据爬取的方法详解

import requests
import json
headers = {
    'Accept':'application/json, text/javascript, */*; q=0.01',
    'X-Requested-With':'XMLHttpRequest',
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36',
    'Content-Type':'application/json',
    'Accept-Encoding':'gzip, deflate',
    'Accept-Language':'zh-CN,zh;q=0.8',
    'Cache-Control':'no-cache',
  }
#空的对象，body参数
data = {}
data = json.dumps(data)
page = 0
url = '网站地址，后面为参数?param1=1¶m1='+str(page)
response = requests.post(url = url,data=data ,headers =headers )
print(response.url)
print(response.text)

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import requests
import json
url = 'http://official-account/app/messages/group'
body = {"type": "text", "content": "测试文本", "tag_id": "20717"}
headers = {'content-type': "application/json", 'Authorization': 'APP appid = 4abf1a,token = 9480295ab2e2eddb8'}
#print type(body)
#print type(json.dumps(body))
# 这里有个细节，如果body需要json形式的话，需要做处理
# 可以是data = json.dumps(body)
response = requests.post(url, data = json.dumps(body), headers = headers)
# 也可以直接将data字段换成json字段，2.4.3版本之后支持
# response = requests.post(url, json = body, headers = headers)
# 返回信息
print response.text
# 返回响应头
print response.status_code
