HTTP POST在OWIN自托管Web API中不起作用 [英] HTTP POST not working in OWIN Self-Host Web API

问题描述

我是自我托管Web API的人.我从集成测试中获得的任何Get Reqeust都可以正常工作.但是，任何POST请求都将引发连接被拒绝.我似乎无法掌握正在发生的事情.

I am self self hosting a Web API. Any Get Reqeust I make from my integration tests works fine. However any POST request throws connection refused. I can't seem to get a handle on what is happening.

错误消息

system.Net.HttpRequestException: An error occured while sending the request to the remote server. SocketException: no connection could be made because the target machine actively refused. 

代码

using (WebApp.Start<App_Start.TestConfiguration>("http:/localhost:8216"))
{
    var client = new HttpClient();
    client.BaseAddress = new System.Uri("http://127.0.0.1:8216");

    var response = await client.PostAsync("/api/MyController", new StringContent("something"));
}

控制器

public string Post(string value)
{
    return "Hello!";
}

推荐答案

我遇到了同样的问题，发现有必要在方法参数之前使用[FromBody]属性.在这种情况下，它可以解析请求有效负载，并且您可以访问方法

I've got the same issue and found that it is necessary to use [FromBody] attribute before your method params. In this case it can parse request payload and you can reach your methods
