python dwebsocket在django中使用

先用pip install websocket安装；
1.配置路由url.py
2在views中的操作：

新增
from dwebsocket.decorators import  accept_websocket,require_websocket
@accept_websocket
def mywebsocket(request):
    judgelis = ['judge1','judge2','judge3','judge4','judge5','judge6','judge7','judge8','min_score','max_score','mean_score']
    judgelist= []

    if request.is_websocket():
        while 1:
            time.sleep(1) ## 向前端发送时间
            judgelistem = []
            groups = Groups.objects.all()
            for group in groups:
                dictem = {}
                for sco in judgelis:
                    if getattr(group,sco) == 0:
                        dictem[sco] = ''
                    else:
                        dictem[sco] = getattr(group,sco)
                judgelistem.append(dictem)
            if judgelistem != judgelist:
                judgelist = copy.deepcopy(judgelistem)
                request.websocket.send(json.dumps({'content':judgelist}))

在前端的操作：

function mywebsocket(){
    console.log(1);
    ws = new WebSocket('ws://127.0.0.1:8000/display/mark/websocket');
    ws.onopen = function(){
        ws.send('发送数据中....')
    };
    ws.onmessage = function (e){
        let received_meg =$.parseJSON(e.data).content;
        console.log('接收数据.....');
        console.log(received_meg);
    };
     ws.onclose = function(){
        console.log('链接已断开.....');
     };
};
