Javascript 如何从angularjs控制器获取数据

嘿，伙计们，我可以知道如何从控制器获取数据吗

比如说

controller.js

function RegisterCtrl($scope, $http, $location) {
    $scope.form = {};
  $scope.submitPost = function() {
    $http.post('/register', $scope.form).
      success(function(data) {
        $location.path('/');
      });
  };

}

app.post('/register', sessionHandler.handleSignup);

 this.handleSignup = function(req, res, next) {
        "use strict";
     // when i try to access into the controller by using "data" it said my "data" 
     // is not declare, what should i pass into `var data` = ?? in order to
     // access the data from controller 

        var email = data.email,
         confirmEmail = data.confirmEmail,
         password = data.password,
         confirmPassword = data.confirmPassword,
         firstName = data.firstName,
         lastName = data.lastName,
         penName = data.penName,
         publicUsername = data.publicUsername;
}

routes/index.js

function RegisterCtrl($scope, $http, $location) {
    $scope.form = {};
  $scope.submitPost = function() {
    $http.post('/register', $scope.form).
      success(function(data) {
        $location.path('/');
      });
  };

}

app.post('/register', sessionHandler.handleSignup);

 this.handleSignup = function(req, res, next) {
        "use strict";
     // when i try to access into the controller by using "data" it said my "data" 
     // is not declare, what should i pass into `var data` = ?? in order to
     // access the data from controller 

        var email = data.email,
         confirmEmail = data.confirmEmail,
         password = data.password,
         confirmPassword = data.confirmPassword,
         firstName = data.firstName,
         lastName = data.lastName,
         penName = data.penName,
         publicUsername = data.publicUsername;
}

路由/session.js

function RegisterCtrl($scope, $http, $location) {
    $scope.form = {};
  $scope.submitPost = function() {
    $http.post('/register', $scope.form).
      success(function(data) {
        $location.path('/');
      });
  };

}

app.post('/register', sessionHandler.handleSignup);

 this.handleSignup = function(req, res, next) {
        "use strict";
     // when i try to access into the controller by using "data" it said my "data" 
     // is not declare, what should i pass into `var data` = ?? in order to
     // access the data from controller 

        var email = data.email,
         confirmEmail = data.confirmEmail,
         password = data.password,
         confirmPassword = data.confirmPassword,
         firstName = data.firstName,
         lastName = data.lastName,
         penName = data.penName,
         publicUsername = data.publicUsername;
}

从http post中的成功响应中，您可以为其分配一个作用域，然后将其显示给您的分区。像这样的

$http.post('/register', $scope.form).
  success(function(data) {
    $scope.data = data;
  });

然后从你的观点来看

<div>{{data}}</div>

{{data}

关于，

您必须使用

express.urlencoded（）

和

express.json（）

来解析通过

HTTP

/

POST

/

PUT

发送的身体数据

之后，

req

对象上将有一个

body

属性，您可以这样使用它：

this.handleSignup = function(req, res, next) {
    "use strict";

    var data = req.body,
        email = data.confirmEmail,
        // etc.
};

您好，谢谢您的回答，我是否必须在我的应用程序中包含这3个中间件？app.use（express.bodyParser（））；app.use（express.urlencoded（））；app.use（express.json（））您好，谢谢您的回复，我需要将数据传递到函数中，以便在插入数据库后执行验证，而不是显示它。
