Question

我的IONIC应用程序有问题。我想在$ http.post之后通过$ http.get从nodeJS重新加载我的数据。这是我的代码：

.controller('todoTodayCtrl', 
function($scope, AuthService, API_ENDPOINT, $http, $state, $ionicPopup) {
  $http.get(API_ENDPOINT.url + '/today').then(function(result) {
      $scope.todaylist = result.data.msg;
  });
})

.controller('todoTodayNewCtrl', 
function($scope, AuthService, API_ENDPOINT, $http, $state, $ionicPopup){
    $scope.today = {
        title: ''
    };
    $scope.todoNewButton = function() {
        $http.post(API_ENDPOINT.url + '/today', $scope.today).then(function(result) {
            $state.go('menu.todoToday');
        }, function(errMsg) {
            var alertPopup = $ionicPopup.alert({
                title: 'Nelze přidat Todo',
                template: errMsg
            });
        });
    };
})

和第一页

<ion-view title="Todo Today" ng-controller="todoTodayCtrl">
<ion-content overflow-scroll="true" padding="true" class="has-header">
    <ion-list>
        <ion-item class="item-divider"  ng-repeat="today in todaylist">{{today.title}} - {{today.time}}</ion-item>
        <button class="button button-stable button-block " ui-sref="menu.todoTodayNew">Přidat todo</button>
    </ion-list>
</ion-content>

和带表单的页面

<ion-view title="Nové todo today">
<ion-content overflow-scroll="true" padding="true" class="has-header">
    <ion-list>
        <label class="item item-input">
            <span class="input-label">Nový úkol</span>
            <input type="text" placeholder="Nová položka" ng-model="today.title">
        </label>
        <button class="button button-stable button-block " ng-click="todoNewButton()">Přidat todo today</button>
    </ion-list>
</ion-content>

Answer 1

您必须在POST请求回调中的$ scope.todaylist中推送新的今日值：

$http.post(API_ENDPOINT.url + '/today', $scope.today).then(function(result) {
    $scope.todaylist.push(result);
    $state.go('menu.todoToday');
}, function(errMsg) {
    var alertPopup = $ionicPopup.alert({
        title: 'Nelze přidat Todo',
        template: errMsg
    });
});

或者通过$ state将结果传递给你的todoTodayCtl。

$state.go('menu.todoToday', {myParam: {some: 'thing'}})

$stateProvider.state('menu.todoToday', {
                url: '/myState',
                params: {myParam: null}, ...

然后访问控制器中的参数。

$stateParams.myParam //should be {some: 'thing'}

我的服务器NodeJs

    apiRoutes.post('/today', passport.authenticate('jwt', {session: false}), function(req, res) {
  var token = getToken(req.headers);
  if (token) {
    var decoded = jwt.decode(token, config.secret);
    User.findOne({
      name: decoded.name
    }, function(err, user) {
      if (err) throw err;

      if (!user) {
        return res.status(403).send({success: false, msg: 'Authentication failed. User not found.'});
      } else {
        console.log(req.body.title);
        var newToday = new Today({
          title: req.body.title,
          time: 'Timeee',
          user: user.name
        });
        newToday.save(function(err) {
          if (err) {
            res.json({succes: false, msg: 'Error'});
          } else {
            res.status(200).json({succes: true, msg: newToday});
          }
        });
      }
    });
  } else {
    return res.status(403).send({success: false, msg: 'No token provided.'});
  }
});

解决

public class Point {

    private double x, y;

    public Point(double x, double y) {
        this.x = x;
        this.y = y;
    }

    public static void main(String[] args) {
        Point[] objectPoints = new Point[3];
        double x[] = {3,4,5};
        double y[] = {4,5,6};

        for (int i = 0; i < objectPoints.length; i++) {
            objectPoints[i] = new Point(x[i], y[i]);
        }
    }

}

在$ http.post之后用$ http.get重新加载控制器
