在AngularJS项目中集成WebSocket以实现实时通信,可以按照以下步骤进行:
app.service('WebSocketService', function($rootScope) {
var socket = null;
this.connect = function(url) {
socket = new WebSocket(url);
socket.onopen = function() {
console.log('WebSocket connection opened');
};
socket.onmessage = function(event) {
$rootScope.$broadcast('websocket-message', event.data);
};
socket.onclose = function() {
console.log('WebSocket connection closed');
};
socket.onerror = function(error) {
console.error('WebSocket error:', error);
};
};
this.send = function(message) {
if (socket && socket.readyState === WebSocket.OPEN) {
socket.send(message);
} else {
console.error('WebSocket is not open');
}
};
this.disconnect = function() {
if (socket) {
socket.close();
socket = null;
}
};
});
WebSocketService
并使用它来建立连接、发送消息和监听消息。app.controller('MyController', function($scope, WebSocketService) {
$scope.message = '';
// 建立WebSocket连接
WebSocketService.connect('ws://example.com/socket');
// 监听WebSocket消息
$scope.$on('websocket-message', function(event, data) {
console.log('Received message:', data);
// 处理接收到的消息
});
// 发送消息
$scope.sendMessage = function() {
WebSocketService.send($scope.message);
$scope.message = '';
};
});
通过以上步骤,你可以在AngularJS项目中成功集成WebSocket以实现实时通信。
