使用Angularjs连接到signalr时出现404错误

大家好我正在努力实现一个SignalR股票代码使用AngularJS基于这里的一个例子。 但我连接到这样的信号器时出现错误GET http：// localhost：9000 / signalr / negotiate？clientProtocol = 1.5＆connectionData =％5B％7B％22name％22％3A％22stockticker％22％7D％5D＆_ = 1480526019939 404（未找到）

这是我的jquery文件中显示错误的地方：

try { // Do send the request (this may raise an exception) xhr.send( options.hasContent && options.data || null ); } catch ( e ) { // #14683: Only rethrow if this hasn't been notified as an error yet if ( callback ) { throw e; } } 

这是我的signalr-hub.js：

 angular.module('SignalR', []) .constant('$', window.jQuery) .factory('Hub', ['$', function ($) { //This will allow same connection to be used for all Hubs //It also keeps connection as singleton. console.log("God help me"); var globalConnections = []; function initNewConnection(options) { var connection = null; if (options && options.rootPath) { connection = $.hubConnection(options.rootPath, { useDefaultPath: false }); } else { connection = $.hubConnection(); } connection.logging = (options && options.logging ? true : false); return connection; } function getConnection(options) { var useSharedConnection = !(options && options.useSharedConnection === false); if (useSharedConnection) { return typeof globalConnections[options.rootPath] === 'undefined' ? globalConnections[options.rootPath] = initNewConnection(options) : globalConnections[options.rootPath]; } else { return initNewConnection(options); } } return function (hubName, options) { var Hub = this; Hub.connection = getConnection(options); Hub.proxy = Hub.connection.createHubProxy(hubName); Hub.on = function (event, fn) { Hub.proxy.on(event, fn); }; Hub.invoke = function (method, args) { return Hub.proxy.invoke.apply(Hub.proxy, arguments) }; Hub.disconnect = function () { Hub.connection.stop(); }; Hub.connect = function (queryParams) { var startOptions = {}; if (options.transport) startOptions.transport = options.transport; if (options.jsonp) startOptions.jsonp = options.jsonp; if (angular.isDefined(options.withCredentials)) startOptions.withCredentials = options.withCredentials; if(queryParams) Hub.connection.qs = queryParams; return Hub.connection.start(startOptions); }; if (options && options.listeners) { Object.getOwnPropertyNames(options.listeners) .filter(function (propName) { return typeof options.listeners[propName] === 'function';}) .forEach(function (propName) { Hub.on(propName, options.listeners[propName]); }); } if (options && options.methods) { angular.forEach(options.methods, function (method) { Hub[method] = function () { var args = $.makeArray(arguments); args.unshift(method); return Hub.invoke.apply(Hub, args); }; }); } if (options && options.queryParams) { Hub.connection.qs = options.queryParams; } if (options && options.errorHandler) { Hub.connection.error(options.errorHandler); } if (options && options.stateChanged) { Hub.connection.stateChanged(options.stateChanged); } //Adding additional property of promise allows to access it in rest of the application. if(options.autoConnect === undefined || options.autoConnect){ Hub.promise = Hub.connect(); } return Hub; }; }]); // Common.js package manager support (eg ComponentJS, WebPack) if (typeof module !== 'undefined' && typeof exports !== 'undefined' && module.exports === exports) { module.exports = 'SignalR'; } 

由于我是信号概念的新手，因此它有很多混乱。 那么，任何人都可以帮助我解决这个问题。
