爬虫代码：

import requests
headers = {
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36',
    'Referer':'https://www1.rmfysszc.gov.cn/projects.shtml?dh=3&gpstate=1&wsbm_slt=1'
    
}
form_data  = {
          "type": "0",
          "name": "",
          "area": "河南省",
          "city": "河南省",
          "city1": "==请选择==",
          "city2": "==请选择==",
          "xmxz": "0",
          "state": "0",
          "money": "",
          "money1": "",
          "number": "0",
          "fid1": "",
          "fid2": "",
          "fid3": "",
          "order": "0",
          "page": "1",
          "include": "0"
}
response = requests.post('https://www1.rmfysszc.gov.cn/ProjectHandle.shtml',data=form_data,headers=headers)

print(response.status_code)
print(response.text)

打印返回结果：

<script>document.cookie=('_')+('_')+('j')+('s')+('l')+('_')+('c')+('l')+('e')+('a')+('r')+('a')+('n')+('c')+('e')+('_')+('s')+('=')+(-~false+'')+((1+[4]>>1)+'')+(~~[]+'')+(3+6+'')+(1+8+'')+(6+'')+(-~false+'')+(-~false+'')+((+false)+'')+((+[])+'')+('.')+(2+4+'')+('|')+('-')+(-~{}+'')+('|')+('B')+((1+[0])/[2]+'')+('S')+('T')+('S')+('w')+('F')+('%')+((1<<1)+'')+('F')+('P')+(0+1+0+1+'')+('N')+('y')+('M')+('X')+('N')+('m')+('Y')+('z')+((+true)+'')+((+true)+'')+('n')+('Q')+('y')+('p')+('f')+('B')+('M')+('%')+(3+'')+('D')+(';')+(' ')+('M')+('a')+('x')+('-')+('a')+('g')+('e')+('=')+(1+2+'')+((1+[2])/[2]+'')+((+[])+'')+(~~{}+'')+(';')+(' ')+('P')+('a')+('t')+('h')+('=')+('/')+(';')+(' ')+('S')+('a')+('m')+('e')+('S')+('i')+('t')+('e')+('=')+('N')+('o')+('n')+('e')+(';')+(' ')+('S')+('e')+('c')+('u')+('r')+('e');location.href=location.pathname+location.search</script>

后来打印状态码发现是521？

解决办法：

爬虫代码headers中添加网页cookie

注意：如何已添加cookie，出现断网情况，需要重新获取cookie

修改后的代码：
