/socket.io/*404找不到烧瓶

Question

我想让socketio正常工作.当我使用以下javascript加载我的页面时.它尝试按预期拉出socket.io页面,但每次都找不到404.

<div id="result"></div>
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="//code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<script src="https://cdn.socket.io/socket.io-1.2.1.js"></script>
<script>
$(function(){
    var socket = io.connect('/endpoint');

    // on receive append data.sound and linebreak to result id on page
    socket.on('receive', function(data){
        $('#result').append(data.mytext);
    });

    $('form#emit').submit(function(event) {
        socket.emit('submit', {account: $('#account').val(),
...

这是socketIO要使用的flask端点

@app.route('/socket.io/<path:remaining>')
def iocg(remaining):
    from websocketinstructions import WebSocketInstructions
    socketio_manage(request.environ, {'/endpoint': WebSocketInstructions}, request)
    return 'done'
