1.首先界面是一个简单的分页查询

2.刷新一下，发现数据是ajax请求的

3.查相关参数

4.点击一条记录进去

5.发现数据也是ajax请求的

6.查看参数发现，是根据之前的ID查询的

7.开始work，首先爬取前面数据的ID，在根据ID爬取社会信用码

import json
import requests
import re
all_count=0
page_count=[1]
page_size=15
data_id=[]
social_credit_code=[]

def post1(url):
    while True:
        print(page_count[0])
        headers = {
            "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36"
        }
        params = {
            'on': True,
            'page': page_count[0],
            'pageSize ': 15,
            'productName ': '',
            'conditionType ': 1,
            'applyname ': '',
            'applysn ': '',
        }

        res = requests.post(url=url, params=params, headers=headers)
        json_data = res.json()
        for i in json_data['list']:
            #打印每次获取的ID值
            print(i["ID"])
            data_id.append(i["ID"])

        # 获取总页数
        all_count = json_data['pageCount']
        # 判断分页是否结束自定义页数
        if page_count[0] == 5:
            break
        else:
            page_count[0] += 1
    print(data_id)

def post2(url, data_id):

    headers = {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36"
    }

    for i in data_id:
        params = {
            'id': i
        }
        res = requests.post(url=url, params=params, headers=headers)
        json_data = res.json()
        #打印每次获取的社会信用代码
        print(json_data['businessLicenseNumber'])
        social_credit_code.append(json_data['businessLicenseNumber'])

if __name__ == '__main__':
    url = "http://125.35.6.84:81/xk/itownet/portalAction.do?method=getXkzsList"
    url2 = "http://125.35.6.84:81/xk/itownet/portalAction.do?method=getXkzsById"

    post1(url)
    post2(url2,data_id)
    print(social_credit_code)
