天眼查数据抓取

正常访问最多获取一页数据,要登录才能获取两页数据,也可以去淘宝花费1,2块买个vip,这样就能获取多条数据了.

我们先随便搜索一个关键词公司

然后先选择一个城市当中一个区

我们正常进来按F12刷新后都会以为是下方接口

确确实实里面有数据,但是有坑.我们网络爬虫一定要细致!!!想想要是我爬第二页或爬别的地区是不是载荷有变化.先说说坑在那吧.

正常这里get请求传header之后就能获取,切记这里别急着bs4解析数据其实在图2里有json数据

只需要进行切片获取到数据进行字符串转json数据就可以键值对提取了

接下来就是开篇了.

其实这里这个接口是错误的,在这里可以这样操作,先清除所有响应数据,然后直接换到第二页

这里就看出来url的不同了,而且是post请求

然后我们查看载荷,不难看出pageNum是换页码的,filterJson里可以改省,市,区

然后复制下面所有请求标头

import requests,json
# -*- coding: utf-8 -*-
url = 'https://capi.tianyancha.com/cloud-tempest/web/searchCompanyV4?_=172855916907'
header = {

在这里可能就用同学有疑问了.

  • 使用 json 参数时,数据会被序列化为 JSON 格式,适合发送 JSON 数据的场合。
  • 使用 data 参数时,数据以表单形式发送,适合传统的表单提交。
    data = {
        "filterJson": '{"economicTypeMethod":{"key":"economicTypeMethod","items":[{"value":"1"}]},"institutionTypeMethod":{"key":"institutionTypeMethod","items":[{"value":"1"}]},"word":{"key":"word","items":[{"value":"水果"}]},"areaCode":{"key":"areaCode","items":[{"value":"00430000V2020","childList":[{"value":"00430100V2020","childList":[{"value":"00430%dV2020"}]}]}]}}'%102,
        "searchType": 1, "sessionNo": "1728560135.23681122", "allowModifyQuery": 1,
        "reportInfo": {"page_id": "SearchResult", "page_name": "主搜搜索结果页", "tab_id": "company", "tab_name": "公司",
                       "search_session_id": "1728560135.23681122", "distinct_id": "322165439"}, "pageNum": 1,
        "pageSize": 20}
    req = requests.post(url=url,headers=header,json=data).json()
    print(req)

    如果想用data=data传参,就需要进行json格式.

  • data = {
        "filterJson": '{"economicTypeMethod":{"key":"economicTypeMethod","items":[{"value":"1"}]},"institutionTypeMethod":{"key":"institutionTypeMethod","items":[{"value":"1"}]},"word":{"key":"word","items":[{"value":"水果"}]},"areaCode":{"key":"areaCode","items":[{"value":"00430000V2020","childList":[{"value":"00430100V2020","childList":[{"value":"00430%dV2020"}]}]}]}}'%102,
        "searchType": 1, "sessionNo": "1728560135.23681122", "allowModifyQuery": 1,
        "reportInfo": {"page_id": "SearchResult", "page_name": "主搜搜索结果页", "tab_id": "company", "tab_name": "公司",
                       "search_session_id": "1728560135.23681122", "distinct_id": "322165439"}, "pageNum": 1,
        "pageSize": 20}
    data = json.dumps(data)
    req = requests.post(url=url,headers=header,data=data).json()
    print(req)
