我试图在角色表单上发布一些JSON数据到我的ASP.NET5 MVC6控制器动作.模型绑定器似乎不起作用.不知道我在这里缺少什么.
我的ASP控制器:
public class DefaultController : Controller { public IActionResult Index() { return View(); } [HttpPost] public IActionResult SubmitTest(QTestViewModel model) { return Json("true"); } }
我的角度控制器:
angular.module("testActiveMq", []) .controller("MqTestController", ["$scope", "$http", function ($scope, $http) { // Submit Form $scope.submitForm = function () { debugger; var formData = (this.data) ? angular.toJson(this.data) : null; if (formData && this.qForm && this.qForm.$valid) { $http({ url: "/Default/SubmitTest", data: formData, method: "POST", dataType: "json", contentType: "application/json; charset=utf-8" }) .then(function successCallback(response) { debugger; // this callback will be called asynchronously // when the response is available }, function errorCallback(response) { debugger; // called asynchronously if an error occurs // or server returns response with an error status. }); } }; }])
我的视图模型:
public class QTestViewModel { public string MqBrokerUri { get; set; } public string ClientId { get; set; } public string UserName { get; set; } public string Password { get; set; } public int TotalRequests { get; set; } public int MaxConcurrentRequests { get; set; } public int DelayBetweenThreads { get; set; } }
当我发出请求时,HTTP标头是......
POST /Default/SubmitTest HTTP/1.1 Host: localhost:50877 Connection: keep-alive Content-Length: 225 Accept: application/json, text/plain, */* Origin: http://localhost:50877 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.86 Safari/537.36 Content-Type: application/json;charset=UTF-8 Referer: http://localhost:50877/ Accept-Encoding: gzip, deflate Accept-Language: en-US,en;q=0.8
我的表单数据看起来像..
{"MqBrokerUri":"ssl://broker-uri:1616?transport.acceptInvalidBrokerCert=true","ClientId":"MqLoadTest","UserName":"myunm","Password":"mypwd","TotalRequests":100,"MaxConcurrentRequests":10,"DelayBetweenThreads":1}
我觉得我错过了一些非常明显的东西.为什么我的JSON数据不能绑定到我的模型?当然,我不需要定制模型粘合剂来实现这么简单的事情吗?
您的代码足以在MVC 5及更早版本中接收控制器中的模型.但是在MVC 6中,您还需要[FromBody]
在控制器操作中设置参数:
[HttpPost] public IActionResult SubmitTest([FromBody]QTestViewModel model) { return Json("true"); }
不确定为什么这是MVC 6中的要求,但是如果你不添加FromBody属性,你的模型将保持其默认值.
检查官方文档中的Web API教程.
在深入挖掘源代码之后,似乎BodyModelBinder
只会接受专门启用了body绑定源的模型,这样就完成了添加[FromBody]
属性.
var allowedBindingSource = bindingContext.BindingSource; if (allowedBindingSource == null || !allowedBindingSource.CanAcceptDataFrom(BindingSource.Body)) { // Formatters are opt-in. This model either didn't specify [FromBody] or specified something // incompatible so let other binders run. return ModelBindingResult.NoResultAsync; }
PS.Angular默认是字符串化json对象,但如果你使用类似jQuery的东西,你还需要手动调用JSON.stringify
.
