方法有什么问题？'stream' 是我声明的用于启动流媒体的方法名称，它可以工作。但是，当我编写此方法来断开流媒体时，错误提示“str”对象没有属性“disconnect”。谁能给我举个例子或告诉我我错过了什么？

def twitter_stop(request):
    stream = request.session['stream']

    stream.disconnect()
     return HttpResponse(request)

更新：这是我正在工作的启动方法：

def twitter_start(request):
     stream = MyStreamer(settings.CONSUMER_KEY, settings.CONSUMER_SECRET,
                settings.ACCESS_TOKEN_KEY, settings.ACCESS_TOKEN_SECRET)
     # get the stream object from the SESSION
      request.session['stream'] = stream
     # get the keywords from the models
        keywords = Keys.objects.all()
        stream.statuses.filter(track=keywords)
         return HttpResponse(request)

2个请求对象不同； 您在request.session中的twitter_start中分配的流在执行该函数后会丢失。使用全局变量来存储流，例如：

global STREAM

def twitter_start(request):
    global STREAM
    STREAM = MyStreamer(settings.CONSUMER_KEY, settings.CONSUMER_SECRET,
                        settings.ACCESS_TOKEN_KEY, settings.ACCESS_TOKEN_SECRET)

    # get the keywords from the models
    keywords = Keys.objects.all()
    STREAM.statuses.filter(track=keywords)
    return HttpResponse(request)

def twitter_stop(request):
    STREAM.disconnect()
    return HttpResponse(request)
