MVC4 webapi 一个Controller中 多个HttpPost方法报错500 Internal Server Error

WebApiConfig:

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

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

Controller:

[HttpPost]
        public RetailSaleGetPriceResult GetPrice(RetailSaleGetPriceInModel argData)
        {
...
        }
       [HttpPost]
        public RetailSalePrepareResult Prepare(RetailSalePrepareInModel argData)
        { ... }

为什么配多个，没必要吧。

DefaultApi要么指定defaultAction，要么删除

这是服务器内部错误，通常这种问题原因有很多，建议你加一个异常筛选器，去捕获这个异常，然后再一步步找到问题点。

/// <summary>
/// 全局异常筛选器
/// </summary>
public class GlobalExceptionFilterAttribute : ExceptionFilterAttribute
{
    /// <summary>
    /// 引发异常事件
    /// </summary>
    /// <param name="actionExecutedContext"></param>
    public override void OnException(HttpActionExecutedContext actionExecutedContext)
    {
        ///在这里统一拦截了API的异常返回信息
        Exception exception = GetRealException(actionExecutedContext.Exception);
        
        var rsJosn = new { Code = 500, Msg = exception.Message, ExMsg = exception.ToString() };
        var response = actionExecutedContext.Response ?? new HttpResponseMessage();
        response.Content = new StringContent(Json.Encode(rsJosn), Encoding.UTF8, "application/json");
    }

    private Exception GetRealException(Exception ex)
    {
        if (ex.InnerException == null)
        {
            return ex;
        }
        return GetRealException(ex.InnerException);
    }
}

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        //其它操作.......

        // Web API Filter
        config.Filters.Add(new GlobalExceptionFilterAttribute());

        //其它操作.......
    }
}
