VS2013，WebApi。

 

2.1异步模式的响应

2.     {
3.         Task<System.Net.Http.HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken);
4.     }

 

2.2 HTTP消息结构封装：

 

2.3 NotFound,Ok

1. public IHttpActionResult GetProduct(int id)
2. {
3.     var product = products.FirstOrDefault(zw => zw.Id == id);
4.     if(product == null)
5.     {
6.         return NotFound();
7.     }
8.  
9.     return Ok(product);
10. }

 

2.4 jquery

 

1. $.getJSON(uri)
2.                 .done(function (data) {
3.                     // On success, 'data' contains a list of products.
4.                     $.each(data, function (key, item) {
5.                         // Add a list item for the product.
6.                         $('<li>', { text: formatItem(item) }).appendTo($('#products'));
7.                     });
8.                 });
