这个错误提示是因为在调用`get_base_area`函数时，传入的`url`参数格式不正确，缺少了协议头（http或https），导致requests库无法识别这个URL，从而报错。你需要检查一下`url`参数的传入是否正确，如果确保了URL格式的正确性，可以考虑加上异常处理来避免这种错误的发生，例如：

def get_base_area(url, headers):
    try:
        r = requests.get(url, headers=headers)
        r.raise_for_status()
        ws = r.text
        s1 = r'https://www.cobases.com/.*?/'
        print(re.findall(s1, ws)[0])
        return get_detail_area(re.findall(s1, ws)[0], headers)
    except requests.exceptions.RequestException as e:
        print(e)
        return None

在这个例子中，我们使用了try-except语句来捕获requests请求发生的异常，并将异常信息打印出来。这样可以帮助我们更好地定位问题所在。
