角度发布到MVC Web API问题 [英] angular posting to an MVC Web API problem

问题描述

我想学习角度。我目前正在学习 $ http 对我的MVC API的请求。



编辑：慢慢发现问题，它与将数据从表单推送到数组有关。我得到的错误信息是TypeError：将循环结构转换为JSON



我有一个简单的，我的意思是简单的HTML表单，可以让我收集2件信息并将其收集到Angularjs数组中，然后将其传递给WEB API方法。



但我的主要问题是，如果我调用参数并且输入参数的值为空，则拼写参数不正确。如果我正确拼写参数，它根本不会调用该方法。任何帮助我了解正在发生的事情的指针？



谢谢

 <   div     ng-app   = 演示 >  
 <   div     ng-controller   =  MyController >  
 < ;  输入    type  < span class =code-keyword> =  text    id   =  username   名称  = 用户名   占位符  =  name ...    ng-model   =  user.name  /  >  
 <  输入    type   =  text    id   =  otherdetails    name   =  otherdetails   占位符  =  name ...    ng-model   =  user.name  /  >  
 
 <  按钮   类型  = 按钮    ng-click   = 添加（用户） > 保存<   / button  >  
 <  < span class =code-leadattribute> button     type   = 按钮    ng -click   =  SaveUsers（）  > 保存到Web API <   / button  >  
 <   / div  >  
 <   / div  >  
 

我的Angular代码如下

 angular.module（' 演示'，[]）; 
 angular.modeul（' 演示'）。controller（'  ButtonCtrl'， function （$ scope，$ http）{
 $ scope.user = []; 
 
 $ scope.Add =  function （user）{
 $ scope.user .push（user）; 
}; 
 
 $ scope.SaveUsers =  function （）{
  var  request = $ http（{
 method：  post ，
 url：'  / Home / Index'，
 data：{user：$ scope.user} 
}）; 
 
 request.success（ function （）{
 alert（'  success'）; 
}）; 
 
 request.error（ function （）{
 alter（'  failed'< /跨度>）; 
}）; 
}; 
}; 
 

我的C＃代码

 [HttpPost] 
  public  ActionResult Index（List< Person> user）
 {
 List< Models.Person> data =  new  List< Models.Person>（）; 
 
  return   null ; 
} 
 
  public   class  Person 
 {
  public   string 名称{获取 ;  set ;} 
  public   string 此处{获取; 设置;} 
} 

解决方案

http 对我的MVC API的请求。

Im trying to learn angular. I am currently in the stage of learning about $http requests to my MVC API.

EDIT: Slowly discovering the problem, it has something to do with the the pushing of the data from form into the array. the error message I am getting back is "TypeError: Converting circular structure to JSON"

I have a simple and I mean simple HTML form that allows me to collect 2 pieces of information and collect it into an Angularjs array and then pass it to the WEB API method.

But my main problem is that If I spell the parameter incorrectly if calls the method and the value of the input parameter is blank. If I spell the parameter correctly it doesn't call the method at all. any pointer to help me learn what is going on?

Thanks

<div ng-app="Demo">
  <div ng-controller="MyController">
    <input type="text" id="username" name="username" placeholder="name..." ng-model="user.name"/>
    <input type="text" id="otherdetails" name="otherdetails" placeholder="name..." ng-model="user.name"/>

    <button type="button" ng-click="Add(user)">Save</button>
    <button type="button" ng-click="SaveUsers()">Save To Web API</button>
  </div>
</div>

My Angular code is as follows

angular.module('Demo', []);
angular.modeul('Demo').controller('ButtonCtrl', function($scope, $http) {
  $scope.user = [];

  $scope.Add = function(user) {
    $scope.user.push(user);
  };

  $scope.SaveUsers = function() {
    var request = $http({
      method: "post",
      url: '/Home/Index',
      data: {user: $scope.user }
    });

    request.success(function() {
      alert('success');
    });

    request.error(function() {
      alter('failed');
    });
  };
};

My C# code

[HttpPost]
    public ActionResult Index(List<Person> user)
    {
        List<Models.Person> data = new List<Models.Person>();

        return null;
    }

    public class Person
    {
      public string Name {get;set;}
      public string Here {get;set;}
    }
