在爬虫中遇到如下报错：

Traceback (most recent call last):
  File "C:/Users/xuchunlin/PycharmProjects/A9_25/haiwai__guanwang/11__Gorringes/2__gorringes__no__detail_info.py", line 88, in <module>

    raise SSLError(e, request=request)
requests.exceptions.SSLError: HTTPSConnectionPool(host='auction.gorringes.co.uk', port=443): Max retries exceeded with url: 
/asp/searchresults.asp?ps=25&pg=1&sale_no=181217&st=D (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 
'tls_process_server_certificate', 'certificate verify failed')],)",),))

对于这个错误，查看代码如下

            try:
                result = session.get(url=url,headers=headers,params = data).text
            except:
                result = session.get(url=url, headers=headers, params=data).text

            if 'javascript">setTimeout' in result:
                result = session.get(url=url, headers=headers, params=data).text

因为请求的是https 协议，所以请求禁用证书验证

正常的代码是：

            try:
                result = session.get(url=url,headers=headers,params = data,verify=False).text
            except:
                result = session.get(url=url, headers=headers, params=data,verify=False).text

            if 'javascript">setTimeout' in result:
                result = session.get(url=url, headers=headers, params=data,verify=False).text
