是否有一种简单的方法来修改Web API返回的默认404消息?

没有找到与请求uri匹配的http资源

你需要重写DelegatingHandler抽象类。

来自ASP的统一、一致的错误响应。Net Web API 2

和这里的ASP。. NET Web API异常处理

简单的方法是通过"DelegatingHandler"

  1. 第一步是创建一个继承自DelegatingHandler的新类:

        public class ApiGatewayHandler : DelegatingHandler
    { 
       protected async override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
       {
         var response = await base.SendAsync(request, cancellationToken);
        if (response!=null && response.StatusCode == HttpStatusCode.NotFound)
        {
            var msg = await response.Content.ReadAsStringAsync();
            //you can change the response here
            if (msg != null && msg.Contains("No HTTP resource was found"))
            {
                return new HttpResponseMessage
                {
                    StatusCode = HttpStatusCode.NotFound,
                    Content = new ObjectContent(typeof(object), new { Message = "New Message..No HTTP resource was found that matches the request URI" }, new JsonMediaTypeFormatter())
                };
            }
        }
        return response;
    return response;
}

    }

  2. 然后将这个类注册到web api注册配置文件

    public static void Register(HttpConfiguration config){
    public static void Register(HttpConfiguration config)
    {
        // you config and routes here                
        config.MessageHandlers.Add(new ApiGatewayHandler());
        //....
    }
}

就是这样。同样的方法，如果你需要改变任何其他错误信息
