如何调用ASHX处理程序，并得到结果返回 [英] how to call ASHX handler and getting the result back

问题描述

我创建了一个处理程序而做一些数据库的工作后返回整数值。我想知道我如何能得到这个值，并指定该值通过调用处理程序的标签。

我GOOGLE了它和大多数例子中使用Jquery.AJAX调用来检索值。我相信我也可以通过使用获得的价值。但在我公司的一些限制，我是受限制的使用code后面。

任何例子会有所帮助。

 处理程序：http://somesite.com/Stores/GetOrderCount.ashx?s$c$c=VIC
返回：3
 

需要把这个分配给一个标签控件

我已经试过这么多这么远。<​​/ P>

  HttpWebRequest的要求=（HttpWebRequest的）WebRequest.Create（http://somesite.com/Stores/GetOrderCount.ashx?s$c$c=VIC）;
HttpWebResponse响应=（HttpWebResponse）request.GetResponse（）;
Label1.Text = response.ToString（）//这不起作用
 

解决方案

使用<一个href=\"http://msdn.microsoft.com/en-us/library/fhd1f0sw%28v=vs.80%29.aspx\">WebClient.DownloadString

  Web客户端的客户端=新的WebClient（）;
Label1.Text = client.DownloadString（http://somesite.com/Stores/GetOrderCount.ashx?s$c$c=VIC）;
 

您也可以使用AJAX直接调用处理和更新的标签。

下面是一个jQuery例如：

  $。获得（商店/ GetOrderCount.ashx？s code = VIC'功能（数据）{
  $（'。结果'）HTML（数据）。
}）;
 

I have created a Handler which return integer value after doing some database work. i would like to know how can i get that value and assign that value to Label by calling that handler.

I have googled it and most of the example uses Jquery.AJAX calls to retrieve the value. I am sure i can also get the value by using that. BUT for some limitation in my company i am restricted to use code behind.

Any example will help.

Handler: http://somesite.com/Stores/GetOrderCount.ashx?sCode=VIC
which returns: 3

need to assign this to a label control

i have tried this much so far.

HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://somesite.com/Stores/GetOrderCount.ashx?sCode=VIC");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Label1.Text = response.ToString() // this does not work

解决方案

Use WebClient.DownloadString

WebClient client = new WebClient ();
Label1.Text = client.DownloadString ("http://somesite.com/Stores/GetOrderCount.ashx?sCode=VIC");

You could also directly call your handler using ajax and update the label.

Here is a jQuery example:

$.get('Stores/GetOrderCount.ashx?sCode=VIC', function(data) {
  $('.result').html(data);
});
