我将 Firebase (AngularFire) 与他们的 PHP API 一起使用,并且正在构建在线状态系统。 https://www.firebase.com/docs/managing-presence.html
我开始得到很多参考资料,这感觉不对。
firebase refs 应该存储在 vanilla vars 还是对象中?
controllers.controller('SocialCtrl', function($scope, angularFire) {
var onlineRef = new Firebase($scope.main.firebaseUrl + "/users/" + $scope.main.userId + "/online");
$scope.online = {};
angularFire(onlineRef, $scope, "online");
var usersRef = new Firebase($scope.main.firebaseUrl + "/users");
$scope.users = {};
angularFire(usersRef, $scope, "users");
var productRef = new Firebase($scope.main.firebaseUrl + "/products/" + $scope.main.serieId);
$scope.product = {};
angularFire(productRef, $scope, "product");
var connectedRef = new Firebase($scope.main.firebaseUrl + "/.info/connected");
connectedRef.on("value", function(snap) {
if (snap.val() === true) {
onlineRef.onDisconnect().set(Firebase.ServerValue.TIMESTAMP);
onlineRef.set(true);
}
});
});
或者
$scope.fire = {
refs: {
online: new Firebase($scope.main.firebaseUrl + "/users/" + $scope.main.userId + "/online"),
users: new Firebase($scope.main.firebaseUrl + "/users"),
product: new Firebase($scope.main.firebaseUrl + "/products/" + $scope.main.serieId),
connected: new Firebase($scope.main.firebaseUrl + "/.info/connected")
}
};
angularFire($scope.fire.refs.online, $scope, "fire.online");
angularFire($scope.fire.refs.users, $scope, "fire.users");
angularFire($scope.fire.refs.product, $scope, "fire.product");
angularFire($scope.fire.refs.connected, $scope, "fire.connected");
$scope.fire.refs.connected.on("value", function(snap) {
if (snap.val() === true) {
$scope.fire.refs.online.onDisconnect().set(Firebase.ServerValue.TIMESTAMP);
$scope.fire.refs.online.set(true);
}
});
我并不是要将此作为最佳实践问题。Firebase 太新了,我不想破坏任何我可能还不知道的东西。
