ASP.NET Web API 的简单示例
Demo1：
HTML:

<meta charset="utf-8" />
<title>Comments Test Home Page</title>
<link href="/Content/Demo.css" rel="stylesheet" type="text/css" />

<button id="getComments">Go!</button>
</div>
</div>
<div id="article">
<p>
This first demo shows a very simple GET scenario. Click on the button to
use jQuery to retrieve JSON data from a Web API endpoint and then display
the contents of that payload in the UI.
</p>
<p>
The code represents retrieving data in a manner that any developer familiar
with jQuery would understand.
</p>
</div> <ul data-bind="template: {name: 'commentTemplate', foreach: comments}">
</ul> <script id="commentTemplate" type="text/html">

</script> <script type="text/javascript">

</div>
</body>

JS:
$(function() {
$("#getComments").click(function () {
// We're using a Knockout model. This clears out the existing comments.
viewModel.comments([]);
$.get('/api/comments', function (data) {
// Update the Knockout model (and thus the UI) with the comments received back

viewModel.comments(data);
});
});
});
Demo2：

<p>
See, I told you that last demo would be simple.
</p>
<p>
This demo allows the user to create and delete comments. When we
delete the comment, we use a proper HTTP DELETE request. Again, the
code is still very simple. Note that when we POST a comment, we handle
the proper 201 status code.

This is a demo of paging through data.
</p>
<p>
The "Query String" button calls code that demonstrates how a typical developer
might implement paging today.
</p>
<p>
The "Queryable" button turns it up a notch and shows paging using a service method
that returns an <code>IQueryable</code>. Note that the client code hasn't changed
much at all, but the server code is much simpler.

In this demo, we take advantage of the unobtrusive client validation introduced in
ASP.NET MVC and apply it to a static HTML page.
</p>
<p>
Once you pass the client validation rules, note that we also support validation
happening on the server. If there are any validation errors, we serialize the
model state to JSON and apply the validation back on the client.
