UnicodeError:使用请求时使用“idna”编解码器编码失败。g

Question

我有一个bot，允许用户向一个图像发送一个URL，然后下载该图像，但是我的日志文件中不断出现UnicodeError: encoding with 'idna' codec failed错误。我自己还不能重现这个错误。你知道吗

以下是完整的错误消息：

以下是错误产生的代码段：

def url_received(update: Update, context: CallbackContext):
    message = update.message
    text = message.text.split(' ')

    if len(text) > 1:
        message.reply_text(get_message(message.chat_id, "too_many_urls"))
        return

    text = text[0]
    url = urlparse(text, 'https').geturl()

    # remove extra backslash after https if it exists
    if url.lower().startswith("https:///"):
        url = url.replace("https:///", "https://", 1)

    # get request
    try:
        request = requests.get(url, timeout=3)
        request.raise_for_status()
    except InvalidURL:
        message.reply_markdown(get_message(message.chat_id, "invalid_url").format(url))
        return
    except HTTPError:
        message.reply_markdown(get_message(message.chat_id, "url_does_not_exist").format(url))
        return
    except Timeout or ConnectTimeout:
        message.reply_markdown(get_message(message.chat_id, "url_timeout").format(url))
        return
    except ConnectionError or RequestException or UnicodeError:
        message.reply_markdown(get_message(message.chat_id, "unable_to_connect").format(url))
        return

我也从同一行得到一个UnicodeError: label empty or too long错误。你知道吗

如果有人知道是什么导致了这个错误，我可以如何修复它的帮助将不胜感激。如果是因为用户发送了乱七八糟的网址，我只需要知道他们是怎么乱七八糟的，我可以抓住错误，并向他们发送一条消息，告诉他们哪里出错了。谢谢。你知道吗
