Question

提供者。

我正在使用python请求模块编写一个获取Web程序的标题。我想做错误处理，但我被卡住了。

这是我的代码。

for i in result:
try: 
    print("URL : {}".format(i[0]))
    req = requests.get(i[0], headers=headers, timeout=15)
    html = req.text
    soup = BeautifulSoup(html, 'html.parser')
    title = soup.title.string
    print(title)

except requests.ConnectionError as e:
    print("Error : Network Connection Error <{}>".format(e))

except requests.Response.raise_for_status() as e:
    print("Error: Invalid Response Error.")

except requests.exceptions.Timeout as e:
    print("Error: Timeout Error.")

except requests.TooManyRedirects as e:
    print("Error: Too many Redirects")

except:
    print("Error: Unknown Error.")

这是Python控制台的答案：

URL : url.com
Nice URL

我该如何解决？非常感谢让我知道！

我在使用 request.get 时遇到了同样的问题，我一直遇到和您一样的问题。我发现我正在使用我的 VPN。当我关闭它时，一切都恢复了正常！

我被困在Python请求中的异常处理中
