2.分析

 

VS2013，WebApi。

 

2.1异步模式的响应

public
interface IHttpActionResult

    {

        Task<System.Net.Http.HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken);

    }

 

2.2 HTTP消息结构封装：

 

2.3 NotFound,Ok

public IHttpActionResult GetProduct(int id)

{

    var product = products.FirstOrDefault(zw => zw.Id == id);

    if(product == null)

    {

        return NotFound();

    }

 
    return Ok(product);

}

 

2.4 jquery

 

$.getJSON(uri)

                .done(function (data) {

                    // On success, 'data' contains a list of products.

                    $.each(data, function (key, item) {

                        // Add a list item for the product.

                        $('<li>', { text: formatItem(item) }).appendTo($('#products'));

                    });

                });
