Question

我正在使用Python开发一个简单的API - Bottle。

这就是我使用路由启用API HTTP请求的方式：

@route('/expand')
def expand(url = ""):
    url = request.query.get('url', '')
    if url == "":
        return {"success" : False,
            "start_url" : url,
            "final_url" : "",
            "url_list" : []
            }
    url_list = expandURL(url)
    return {"success" : True,
            "start_url" : url,
            "final_url" : url_list[-1],
            "url_list" : url_list
            }

这是我得到的错误：

这是我如何通过将params={'url':'http://tuq.in/sahil'}发送到提供500内部错误的链接[https://sahildua2305.pythonanywhere.com/expand]来测试来电。在没有任何参数的情况下发送相同的请求不会产生错误！

请帮我纠正错误.. 提前谢谢。

您可能拥有免费帐户，并且不允许互联网访问除白名单网站之外的任何内容。

您在提供参数时仅获得错误的原因是，只有在有参数时才会调用发出请求的代码（在expandURL中）。
