Question

我正在尝试使用Python检查网站列表是否在线。但是，在多个站点上，请求会产生错误的状态代码。例如，即使网站处于在线状态，我获得的https://signaturehound.com/的状态代码仍为500，并且在Chrome开发人员工具中显示的响应代码为200。

我的代码如下：

[DEBUG/MainProcess] created semlock with handle 140000699432960
[DEBUG/MainProcess] created semlock with handle 140000699428864

如@CaptainDaVinci在评论中所建议，解决方案是将代码中的head替换为get：

import requests
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36'}

def url_ok(url):

   r = requests.get(url,timeout=5,allow_redirects=True,headers=headers)
   status_code = r.status_code

   return status_code

print(url_ok("https://signaturehound.com/"))

即使网站可用，Python请求也会产生状态码500
