我正在尝试获取音频 streamURL: mms://186.65.90.12:8080/listen.pls.. 的响应（以检查响应标头内容类型），但出现以下错误：
>>> import requests
>>> r = requests.get("mms://186.65.90.12:8080/listen.pls",stream=True)
Traceback (most recent call last):

raise InvalidSchema("No connection adapters were found for '%s'" % url)
requests.exceptions.InvalidSchema: No connection adapters were found for 'mms://186.65.90.12:8080/listen.pls'
“请求”HTTP 库是否能够处理非 HTTP URL？如果没有，是否有任何替代方案可以使其发挥作用？我已经尝试了 urllib2 没有运气..
