How to POST data to ASP.NET HttpHandler?

Question

I am trying to send a large chunk of data over to a HTTP handler. I can't send it using GET because of the URL length limit so I decided to POST it instead. The problem is that I can't get at the values. context.Request.Form shows that it has 0 items. So is there a way that I can POST data to a HttpHandler?

Answer 1

Having some code to look at would help diagnose the issue. Have you tried something like this?

jQuery code:

$.post('test.ashx', 
       {key1: 'value1', key2: 'value2'}, 
       function(){alert('Complete!');});

Then in your ProcessRequest() method, you should be able to do:

string key1 = context.Request.Form["key1"]; 

You can also check the request type in the ProcessRequest() method to debug the issue.

if(context.Request.RequestType == "POST")
{
    // Request should have been sent successfully
}
else
{
    // Request was sent incorrectly somehow
}

I also had the same problem. It was an client/AJAX problem. I had to set the AJAX call request header "ContentType" to

application/x-www-form-urlencoded

to make it work.
