前段时间，经理让我去找一些企业的信息，我平常习惯于使用爱企查。所以，便想着写一个程序来实现这个，所以有以下的代码：

import json
import requests
import re
from lxml import etree
url="https://aiqicha.baidu.com/s?q="+公司名称+"=0"

res=requests.get(url,headers=headers)

res=res.text.replace('\/','')
res=res.encode('utf-8').decode('unicode_escape')
# res=re.findall('{(.*?)}',res)
res=re.findall(r'{"pid":(.*?)}],',res)
# print(res)
for aa in res:
#     # aa=aa.strip('<em>')
    aa=aa.replace('<em>','')
    aa=aa.replace('<\/em>','')
    # print(aa)
    bb=re.findall(r'"entName":"(.*?)",',aa)
    cc=re.findall(r'"regCap":"(.*?)",',aa)
    bids=re.findall(r'"bid":"(.*?)",',aa)
    gongsiming={'username':'',
                'zijin':'',
                'dizhi':''}
    for ae,ac,bid in zip(bb,cc,bids):
        # print(ae,ac,bid)
        # if ae=="北京蜂盒科技有限公司":
        #     print(ac)
        gongsiming={'username':ae,
                    'zijin':ac,
                    'dizhi':bid}
        # gongsiming['username']=ae
        # gongsiming['zijin']=ac
        # gongsiming['dizhi']=bid
    print(gongsiming)

我这里需要的是公司的名称、注册资金，其他的参数都是不需要的，所以这里我只做了简单的提取，想要提取其他信息，用正则选以下就好了。至于为什么使用正则，主要是因为这个源代码太复杂了，本想用json，但是没搞懂json，使用正则效果也是一样。
