我在我的服务器上使用离子框架和我的服务器上的MEANJS。我正在使用Web套接字来获取实时数据。虽然每次在Android应用程序中发生CRUD时服务器端Web应用程序都会自动更新,但是当在服务器端进行更改时,Android应用程序不会自动更新。
Android App Service (AngularJS)
i
客户端控制器
.service('Socket', ['Authentication', '$state', '$timeout',
function (Authentication, $state, $timeout) {
// Connect to Socket.io server
this.connect = function () {
// Connect only when authenticated
if (Authentication.user) {
this.socket = io('https://cryptic-savannah-60962.herokuapp.com');
}
};
this.connect();
// Wrap the Socket.io 'on' method
this.on = function (eventName, callback) {
if (this.socket) {
this.socket.on(eventName, function (data) {
$timeout(function () {
callback(data);
});
});
}
};
// Wrap the Socket.io 'emit' method
this.emit = function (eventName, data) {
if (this.socket) {
this.socket.emit(eventName, data);
}
};
// Wrap the Socket.io 'removeListener' method
this.removeListener = function (eventName) {
if (this.socket) {
this.socket.removeListener(eventName);
}
};
}
服务器控制器(NodeJS)
if (!Socket.socket && Authentication.user) {
Socket.connect();
}
Socket.on('orderCreateError', function (response) {
$scope.error = response.message;
});
Socket.on('orderCreateSuccess', function (response) {
if ($scope.orders) {
$scope.orders.unshift(response.data);
}
});
Socket.on('orderUpdateSuccess', function (response) {
if ($scope.orders) {
// not the most elegant way to reload the data, but hey :)
$scope.orders = Orders.query();
}
});

您的服务器端有两个发射通道,但在客户端没有处理任何事件。
每socket.io docs,您需要以下内容:
socket.on('orderUpdateSuccess', function (data) {
// do something inside the app that will update the view
console.log(data);
Orders.update(data); // assuming you have a service called Orders to keep track of live data -- don't forget [$scope.$apply][2]
});
使用您的示例代码
Socket.on('orderUpdateSuccess', function (response) {
if ($scope.orders) {
$scope.$apply(function() {
// not the most elegant way to reload the data, but hey :)
$scope.orders = Orders.query();
});
}
});
