简单爬取天眼查数据 附代码

一、常规抓包分析

比如要爬取企业注册信息查询_企业工商信息查询_企业信用信息查询平台_发现人与企业关系的平台-天眼查该页面的基础信息。

通过火狐浏览器抓包，可以发现，所要数据都在下图的json文件里

查看其请求

伪装成浏览器爬取该文件：

伪装成浏览器爬取该文件：

import requests
header = {
'Host': 'www.tianyancha.com',
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0',
'Accept': 'application/json, text/plain, */*',
'Accept-Language': 'zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3',
'Accept-Encoding': 'gzip, deflate',
'Tyc-From': 'normal',
'CheckError': 'check',
'Connection': 'keep-alive',
'Referer': 'http://www.tianyancha.com/company/2310290454',
'Cache-Control': 'max-age=0'
,
'Cookie': '_pk_id.1.e431=5379bad64f3da16d.1486514958.5.1486693046.1486691373.; Hm_lvt_e92c8d65d92d534b0fc290df538b4758=1486514958,1486622933,1486624041,1486691373; _pk_ref.1.e431=%5B%22%22%2C%22%22%2C1486691373%2C%22https%3A%2F%2Fwww.baidu.com%2Flink%3Furl%3D95IaKh1pPrhNKUe5nDCqk7dJI9ANLBzo-1Vjgi6C0VTd9DxNkSEdsM5XaEC4KQPO%26wd%3D%26eqid%3Dfffe7d7e0002e01b00000004589c1177%22%5D; aliyungf_tc=AQAAAJ5EMGl/qA4AKfa/PDGqCmJwn9o7; TYCID=d6e00ec9b9ee485d84f4610c46d5890f; tnet=60.191.246.41; _pk_ses.1.e431=*; Hm_lpvt_e92c8d65d92d534b0fc290df538b4758=1486693045; token=d29804c0b88842c3bb10c4bc1d48bc80; _utm=55dbdbb204a74224b2b084bfe674a767; RTYCID=ce8562e4e131467d881053bab1a62c3a'
}
r = requests.get('http://www.tianyancha.com/company/2310290454.json', headers=header)
print(r.text)

print(r.status_code)

返回结果如下：

状态码为403，常规爬取不成功。考虑下面一种方式。

二、使用selenium+PHANTOMJS获取数据

首先下载phantomjs到本地统一组织机构代码查询，并将phantomjs.exe存放在系统环境变量所在目录下（本人讲该文件放置在D:/Anaconda2/路径下）。

为phantomjs添加useragent信息（经测试，不添加useragent信息爬取到的是错乱的信息）：

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
dcap = dict(DesiredCapabilities.PHANTOMJS)
dcap["phantomjs.page.settings.userAgent"] = (
"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0"
    )
driver = webdriver.PhantomJS(executable_path='D:/Anaconda2/phantomjs.exe', desired_capabilities=dcap)

获取网页源代码：

driver.get('http://www.tianyancha.com/company/2310290454')
#等待5秒，更据动态网页加载耗时自定义
time.sleep(5)
# 获取网页内容
content = driver.page_source.encode('utf-8')
driver.close()
print(content)

对照网页，爬取的源代码信息正确，接下去解析代码，获取对应的信息。

简单写了下获取基础信息的代码：

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from selenium import webdriver
import time
from bs4 import BeautifulSoup
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
def driver_open():
    dcap = dict(DesiredCapabilities.PHANTOMJS)
    dcap["phantomjs.page.settings.userAgent"] = (
"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0"
    )
    driver = webdriver.PhantomJS(executable_path='D:/Anaconda2/phantomjs.exe', desired_capabilities=dcap)
return driver
def get_content(driver,url):
    driver.get(url)
#等待5秒，更据动态网页加载耗时自定义
    time.sleep(5)
# 获取网页内容
    content = driver.page_source.encode('utf-8')
    driver.close()
    soup = BeautifulSoup(content, 'lxml')

return soup
def get_basic_info(soup):
    company = soup.select('div.company_info_text > p.ng-binding')[0].text.replace("\n","").replace(" ","")
    fddbr = soup.select('.td-legalPersonName-value > p > a')[0].text
    zczb = soup.select('.td-regCapital-value > p ')[0].text
    zt = soup.select('.td-regStatus-value > p ')[0].text.replace("\n","").replace(" ","")
    zcrq = soup.select('.td-regTime-value > p ')[0].text
    basics = soup.select('.basic-td > .c8 > .ng-binding ')
    hy = basics[0].text
    qyzch = basics[1].text
    qylx = basics[2].text
    zzjgdm = basics[3].text
    yyqx = basics[4].text
    djjg = basics[5].text
    hzrq = basics[6].text
    tyshxydm = basics[7].text
    zcdz = basics[8].text
    jyfw = basics[9].text
print u'公司名称：'+company
print u'法定代表人：'+fddbr
print u'注册资本：'+zczb
print u'公司状态：'+zt
print u'注册日期：'+zcrq
# print basics

print u'行业：'+hy
print u'工商注册号：'+qyzch
print u'企业类型：'+qylx
print u'组织机构代码：'+zzjgdm
print u'营业期限：'+yyqx
print u'登记机构：'+djjg
print u'核准日期：'+hzrq
print u'统一社会信用代码：'+tyshxydm
print u'注册地址：'+zcdz
print u'经营范围：'+jyfw
def get_gg_info(soup):
    ggpersons = soup.find_all(attrs={"event-name": "company-detail-staff"})
    ggnames = soup.select('table.staff-table > tbody > tr > td.ng-scope > span.ng-binding')
# print(len(gg))
for i in range(len(ggpersons)):
        ggperson = ggpersons[i].text
        ggname = ggnames[i].text
print (ggperson+" "+ggname)
def get_gd_info(soup):
    tzfs = soup.find_all(attrs={"event-name": "company-detail-investment"})
for i in range(len(tzfs)):
        tzf_split = tzfs[i].text.replace("\n","").split()
        tzf = ' '.join(tzf_split)

print tzf
def get_tz_info(soup):
    btzs = soup.select('a.query_name')
for i in range(len(btzs)):
        btz_name = btzs[i].select('span')[0].text
print btz_name
if __name__=='__main__':
    url = "http://www.tianyancha.com/company/2310290454"
    driver = driver_open()
    soup = get_content(driver, url)
print '----获取基础信息----'
    get_basic_info(soup)
print '----获取高管信息----'
    get_gg_info(soup)
print '----获取股东信息----'
    get_gd_info(soup)
print '----获取对外投资信息----'
    get_tz_info(soup)

这仅仅是单页面的一个示例统一组织机构代码查询，要写完整的爬虫项目加工，以后再花时间改进。
