我有一个Web Api控制器,它的行为非常奇怪。当我使用PostMan访问Web Api的POST方法时,一切正常,但是当我使用来自.net的HttpWebRequest时,它返回(405)Method Not Allowed错误。我将Web Api代码放在这里:
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web;
using System.Web.Http;
namespace MyProject.Controllers
{
public class TestController : ApiController
{
[HttpPost]
public int buy(OrderResult value)
{
try
{
if (value.InvoiceDate != null && value.Result == 1)
{
return 0;
}
}
catch{}
return -1;
}
}
public class OrderResult
{
public int Result { get; set; }
public long InvoiceNumber { get; set; }
public string InvoiceDate { get; set; }
public long TimeStamp { get; set; }
}
}
这是我的 WebApiConfig.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;
namespace MyProject
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { action = RouteParameter.Optional, id = RouteParameter.Optional }
);
}
}
}
这是我如何从另一个.NET项目发送POST请求的方式:using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Web;
namespace MyProject.Controllers
{
public static class WebReq
{
public static string PostRequest(string Url, string postParameters)
{
try
{
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(Url);
myReq.Method = "POST";
myReq.Timeout = 30000;
myReq.Proxy = null;
byte[] postData = Encoding.UTF8.GetBytes(postParameters);
myReq.ContentLength = postData.Length;
myReq.ContentType = "application/x-www-form-urlencoded";
using (Stream requestWrite = myReq.GetRequestStream())
{
requestWrite.Write(postData, 0, postData.Length);
requestWrite.Close();
using (HttpWebResponse webResponse = (HttpWebResponse)myReq.GetResponse())
{
if (webResponse.StatusCode == HttpStatusCode.OK)
{
using (Stream str = webResponse.GetResponseStream())
{
using (StreamReader sr = new StreamReader(str))
{
return sr.ReadToEnd();
}
}
}
return null;
}
}
}
catch (Exception e)
{
var message = e.Message;
return null;
}
}
}
}
我已经在我的web.config中添加了以下代码:
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule" />
</modules>
很奇怪,因为我可以在PostMan中成功发送POST请求。 PostMan将此代码发送到API。
POST /api/Test/buy HTTP/1.1
Host: domain.com
Cache-Control: no-cache
Postman-Token: 9220a4e6-e707-5c5f-ea61-55171a5dd95f
Content-Type: application/x-www-form-urlencoded
InvoiceDate=28012016&Result=1
我将感激任何解决问题的建议。
