发布到Web API

Question

处理发布到Web api的最好或更好的方法是什么，如何通过C＃完成？

Web API代码

public class ProcessController : ApiController
{
    [HttpGet]
    public string Test()
    {
        return "Hello from API";
    }


    [HttpPost]
    public IHttpActionResult ApiPost(Model m)
    {
        return Ok();
    }
}

public class Model
{
    public int Id {get; set;}
    public string Name {get; set;}
}

调用Web API的代码

HttpClient client = new HttpClient(new HttpClientHandler { UseDefaultCredentials = true });
client.BaseAddress = new Uri("http://localhost:2478/api/Process/");

HttpResponseMessage response = await client.GetAsync("test");

Model m = new Model ();
m.Id= 4;
m.Name = "test";

var r = client.PostAsJsonAsync("ApiPost", m);

这将返回500内部服务器错误。 这里缺少什么吗？

Web API配置

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        var settings = GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings;
        settings.ContractResolver = new CamelCasePropertyNamesContractResolver();
        settings.Formatting = Formatting.Indented;

        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

    }
}

Answer 1

您是否尝试过：将FromBody属性添加到模型中并发布与主体中的m匹配的模型

[HttpPost]
public IHttpActionResult ApiPost([FromBody] Model m)
{
    return Ok();
}

Answer 2

更改路由代码以包括该操作可解决此问题。 只要它们是一种GET或POST方法，调用Web API的代码就可以正常工作，因为任何调用都将尝试使用其中一种。

如果没有该操作，它将不知道在API控制器中使用哪种方法，因为它无法路由到该方法。

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Dashboard", action = "Index", id = UrlParameter.Optional }
        );
    }
