$http.get 角度和节点错误

Question

My problem is $http.get instruction --> Without $http.get in the main page I get "random 46" (test ok) but if I insert $http.get I get "random {{ number }}" .我的问题是$http.get指令 --> 在主页上没有$http.get我得到"random 46" (test ok) 但是如果我插入$http.get我得到"random {{ number }}" 。

How can I fix this?我该如何解决这个问题？

-server.js
-public
    -core.js
    -index.html

server.js (node backend) server.js（节点后端）

//restful api
app.get('/api/random', function(req, res) {
    res.json({
        "text" : "4"
    });
});

//app
app.get('*', function(req, res) {
    res.sendFile(__dirname + '/public/index.html');
});

core.js (angular frontend) core.js（角度前端）

angular.module("myModule", [])
    .controller('myController', function($scope) {
        $scope.number = 46;

        $http.get('/api/random')
            .then(function successCallback(res) {
                $scope.number = res.data;
                console.log('success');
            }, function errorCallback() {
                console.log('Error');
        });
})

index.html索引.html

<html ng-app="myModule">

<head>
    <!-- META -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1"><!-- Optimize mobile viewport -->

    <title>Random number from sa-mp</title>

    <!-- SCROLLS -->
    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css"><!-- load bootstrap -->
    <style>
        html                    { overflow-y:scroll; }
        body                    { padding-top:50px; }
        #todo-list              { margin-bottom:30px; }
    </style>

    <!-- SPELLS -->
    <script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script><!-- load jquery -->
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.6.7/angular.min.js"></script><!-- load angular -->
    <script src="core.js"></script>

</head>

<!-- SET THE CONTROLLER AND GET ALL TODOS -->
<body ng-controller="myController">
    <div class="container">

        <!-- HEADER AND TODO COUNT -->
        <div class="jumbotron text-center">
            <h1>random <span class="label label-info">{{ number }}</span></h1>
        </div>

    </div>
</body>

</html>

EDIT: I tried编辑：我试过了

res.data
$scope.$apply();

and和

res.data.text
$scope.$apply();

and和

res.text
$scope.$apply();

but it didn't work.但它没有用。

EDIT 2: RESOLVED编辑 2：已解决

I replaced this我换了这个

.controller('myController', function($scope) {

with与

.controller('myController', function($scope, $http) {

and used this to set data并用它来设置数据

$scope.number = res.data.text;

Try to use $scope.$apply() at the last line of your callback.尝试在回调的最后一行使用 $scope.$apply() 。

like:像：

$http.get('/api/random')
    .then(function successCallback(res) {
        $scope.number = res.data.text;
        $scope.$apply();
        console.log('success');
    }, function errorCallback() {
        console.log('Error');
});

If it works.如果它有效。 You can know more about that in this article: http://jimhoskins.com/2012/12/17/angularjs-and-apply.html您可以在本文中了解更多相关信息： http : //jimhoskins.com/2012/12/17/angularjs-and-apply.html

Also, you should get res.data.text to have the right value on your html.此外，您应该让res.data.text在您的 html 上具有正确的值。 like: $scope.number = res.data.text ;像： $scope.number = res.data.text ;
