为什么我只在将数据发布到web api时才收到500错误？ [英] Why I am getting the 500 error only when I am posting the data to web api?

问题描述

您好我正在尝试将数据发布到web api我收到500错误并且没有调用方法。代码如下



这是Model类





< pre lang =c＃> public class 类别
{
public int CategoryId { get ; set ; }
public string CategoryName { get ; set ; }
public string ParentCategoryId { get ; set ; }
public string IsServiceContainer { get ; set ; }
public string ImageUrl { get ; set ; }
public string 描述{ get ; set ; }
public 列表<类别> ChildCategories { get ; set ; }
public string IsActive { get ; set ; }
}

这是控制器方法

 [ResponseType（ typeof （Category））] 
  public  IHttpActionResult PostCategory（类别类别）
 {
  if （！ModelState.IsValid）
 {
  return  BadRequest（ModelState）; 
} 
 ObDataAccess.InsertCategory（category.CategoryName，category.ImageUrl，category.ParentCategoryId，category.IsActive，category.Description，category.IsServiceContainer）; 
  return  CreatedAtRoute（  DefaultApi， new  {id = category.CategoryId}，category）; 
} 
 

这是Angular js服务

  //   /<参考path =D：\FetotAdmin \FetotAdmin \FetotAdmin \Scripts / angular.js/>  
  var  CategoryService = angular.module（'  CategoryService'，[]）; 
 CategoryService.factory（'  CategoryApi'，函数（$ http）{
  var  urlBase =   http：// localhost：60624 / api; 
  var  CategoryApi = {}; 
 CategoryApi .getCategorees =  function （）{
  return  $ http.get（urlBase + '  / Category'）; 
 
}; 
 CategoryApi.AddCategory = < span class =code-keyword> function （category）{
 alert（ JSON  .stringify（category））; 
  //   var req = $ http（{ 
  //  方法： 'post'， 
  //   url：urlBase +'/ Category'， 
  //   data：category  
 
  //  }）;  
  //  < span class =code-comment> return req;  
 
  return  $ http.post（'  http：// localhost：60624 / api / Category /'，category）; 
}; 
  return  CategoryApi; 
 
}）; 

我的尝试：



我尝试使用$ http.post方法。当我调用使用Entity框架创建的web api时，它工作正常，但是当我使用post操作调用self self web api时，仅在发布数据的情况下给出500错误

解决方案

http）{
var urlBase = HTTP：//本地主机：60624 / API;
var CategoryApi = {};
CategoryApi.getCategorees = function （）{
return

http.get（urlBase + ' / Category'）;

};
CategoryApi.AddCategory = function （类别）{
alert（ JSON .stringify （类别））;
// var req =

http（{
// 方法：'post'，
// url：urlBase +'/ Category'，
// 数据：类别

// }）;
// return req;

return

Hi I am trying to post data to web api I am getting 500 error and method is not being called . The code is below

This is the Model class

public class Category
  {
      public int CategoryId { get; set; }
      public string CategoryName { get; set; }
      public string ParentCategoryId { get; set; }
      public string IsServiceContainer { get; set; }
      public string ImageUrl { get; set; }
      public string Description { get; set; }
      public List<Category> ChildCategories { get; set; }
      public string IsActive { get; set; }
  }

This is the controller Method

[ResponseType(typeof(Category))]
     public IHttpActionResult PostCategory(Category category)
     {
         if (!ModelState.IsValid)
         {
             return BadRequest(ModelState);
         }
         ObDataAccess.InsertCategory(category.CategoryName, category.ImageUrl, category.ParentCategoryId, category.IsActive, category.Description, category.IsServiceContainer);
         return CreatedAtRoute("DefaultApi", new { id = category.CategoryId }, category);
     }

this is the Angular js Service

/// <reference path="D:\FetotAdmin\FetotAdmin\FetotAdmin\Scripts/angular.js" />
var CategoryService = angular.module('CategoryService', []);
CategoryService.factory('CategoryApi', function ($http) {
    var urlBase = "http://localhost:60624/api";
    var CategoryApi = {};
    CategoryApi.getCategorees = function () {
        return $http.get(urlBase + '/Category');

    };
    CategoryApi.AddCategory = function (category) {
        alert(JSON.stringify(category));
        //var req = $http({
        //    method: 'post',
        //    url: urlBase + '/Category',
        //    data: category

        //});
        //return req;

        return $http.post('http://localhost:60624/api/Category/', category);
    };
    return CategoryApi;

});

What I have tried:

I tried with $http.post method. when I am calling the web api created with Entity framework it is working fine but when I am calling self created web api with post operation its giving 500 error only in case of post data

解决方案

http) { var urlBase = "http://localhost:60624/api"; var CategoryApi = {}; CategoryApi.getCategorees = function () { return

http.get(urlBase + '/Category'); }; CategoryApi.AddCategory = function (category) { alert(JSON.stringify(category)); //var req =

http({ // method: 'post', // url: urlBase + '/Category', // data: category //}); //return req; return
