c＃ - 405（方法不允许）当从角2应用POST POST

Question

我有点绝望这个问题。我是新的角2和.net，我试图建立一个简单的应用程序。我在c＃中编写了api rest。当我从角度调用GET方法时，它工作正常，但不是POSTmethod。我总是收到405（方法不允许），但是如果我和邮递员一起打电话给所有作品。我发现许多问题都出在同一个问题上，但他们对我来说并不合适。 我启用了CORS。 这里是我的代码：

角

sendPtipo(delegacion,municipio,ejercicio,recinto,tipo){ 
    let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded' }); 
    let options = new RequestOptions({ headers: headers }); 
    let urlPtipo ='http://localhost:50790/ApiProductoTipo/CalculaPTRecinto'; 
    let body ='delegacion='+delegacion+'&municipio='+municipio+'&recinto='+recinto+'&ejercicio='+ejercicio+'&tipo'+tipo; 

return this._http.post(urlPtipo , body , options) 
       .map(data => {alert('ok');}) 
       .catch(this.handleError); 
} 

private extractData(res: Response) { 
    let body = res.json(); 
    return body.data || {}; 
} 

private handleError(error: Response) { 
    console.error(error); 
    return Observable.throw(error.json().error || 'Server error'); 
}}

你的代码似乎ok.Try更改代码，我已经给下面：

角

sendPtipo(delegacion: number,municipio: number,ejercicio: number,recinto: number,tipo: string){ 

     let data = new Object(); 
     data.delegacion = delegacion; 
     data.municipio = municipio; 
     data.ejercicio = ejercicio; 
     data.recinto = recinto; 
     data.tipo = tipo; 

     let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded' }); 
     let options = new RequestOptions({ headers: headers }); 
     let urlPtipo ='http://localhost:50790/ApiProductoTipo/CalculaPTRecinto'; 

    return this._http.post(urlPtipo , data , options) 
        .map(data => {alert('ok');}) 
        .catch(this.handleError); 
    } 

    private extractData(res: Response) { 
     let body = res.json(); 
     return body.data || {}; 
    } 

    private handleError(error: Response) { 
     console.error(error); 
     return Observable.throw(error.json().error || 'Server error'); 
    }} 

C＃中的API

using System.Collections.Generic; 
using System.Web.Http; 
using AppName.Models; 
using AppName.Service; 
using System.Linq; 
using AppName.ViewModels; 
using System.Net.Http; 
using System.Net; 
using System.Web.Http.Cors; 

namespace Api.Services 
{ 
    // Allow CORS for all origins. (Caution!) 
    //[EnableCors(origins: "*", headers: "*", methods: "*")] 
    public class ApiProductoTipoController : ApiController 
    { 
     public class myobj{ 
      public int delegacion { get; set; } 
      public int municipio { get; set; } 
      public int ejercicio { get; set; } 
      public int recinto { get; set; } 
      public string tipo { get; set; } 

     } 

     private readonly IProductoTipoService productoTipoService; 

     public HttpResponseMessage Options() 
     { 
      return new HttpResponseMessage { StatusCode = HttpStatusCode.OK }; 
     } 

     public ApiProductoTipoController(IProductoTipoService productoTipoService) 
     { 
      this.productoTipoService = productoTipoService; 
     } 

     [HttpPost] 
     [Route("~/ApiProductoTipo/CalculaPTRecinto")] 
     public HttpResponseMessage CalculaPTRecinto(myobj data) 
     {   
      var tipo = data.tipo; 
      ... 
     } 
    }} 

我面临同样的数据issue.The实际的数据类型，你SRE发送的API side.That的不能明白为什么它给405 error。那么尝试发送数据作为对象，也接收为对象在API方面。

希望这会帮助你
