Angularjs 角度绑定未使用socket.io广播更新

我有一个名为currentPlayer的服务器变量，它在emit'init'调用中正确绑定，但不会在broadcast.emit中绑定。从客户端传递的变量turnNumber首先会正确更新。当pass事件被触发时，我可以看到currentPlayer在终端中切换值，但我不明白为什么它不会在视图中更新

以前绑定到基元类型时遇到一些问题，所以我尝试执行额外的步骤并将currentPlayer分配给对象数组：$scope.globalVars=[{currentPlayer:data.currentPlayer}]，但这没有帮助

//server
var currentPlayer = 1;
socket.emit('init', {
    currentPlayer: currentPlayer
});
socket.on('pass', function (data) {
    currentPlayer = currentPlayer == 1 ? 2 : 1;
    console.log(currentPlayer);
    socket.broadcast.emit('pass', {
        number: data.turnNumber,
        currentPlayer: currentPlayer
    });
});

//client
socket.on('init', function (data) {
    $scope.globalVar.currentPlayer = data.currentPlayer;
});
socket.on('pass', function (data) {
    $scope.globalVar.turnNumber = data.number;
    $scope.globalVar.currentPlayer = data.currentPlayer;
});
//click event
$scope.globalVar.turnNumber++;
socket.emit('pass', {
    turnNumber: $scope.globalVar.turnNumber
});

<!-- html -->
{{globalVar.currentPlayer}} {{globalVar.turnNumber}}

这些调用似乎是在anuglar上下文之外执行的。尝试在socket.on处理程序中使用$scope.$apply，如

socket.on('pass', function (data) {
   $scope.$apply(function() {
    $scope.globalVar.turnNumber = data.number;
    $scope.globalVar.currentPlayer = data.currentPlayer;
   });
});
