jQuery AJAX Call for posting data to ASP.Net page ( not Get but POST)

Question

I have the following jQuery AJAX call to an ASP.Net page.

             $.ajax({
                async: true,
                type: \"POST\",
                        


        

Answer 1

Option 1. Keep your server side code the same

First remove the kendo.stringify. Then either remove the contentType or change it to...

"application/x-www-form-urlencoded; charset=utf-8" 

...or change your $.ajax call to this:

$.post('DocSummaryDataAsync.aspx', { vendorId: supplierId, businessUnit: busUnit, productSegmentId: prodSegmentId, programId: progId, productManagerId: prodManagerId, companyIds: compIds, expired: exp.toString(), requestType: 'TotalCount' }, function (data) { });

Option 2. Change the POST to GET

Like this

$.ajax({
async: true,
type: "GET",
etc.

This will pass your data via the QueryString. If you remove the kendo.stringify call you would access all the values like this:

string vendorId = Request.QueryString[0];
string businessUnit = Request.QueryString[1];
etc.

Option 3. Use your original $.ajax call

If you use your original $.ajax, then the following applies:

Request.Params gets a "combined collection of QueryString, Form, Cookies, and ServerVariables items." - this link

You are not working with any of those. Instead, you need to access Request.InputStream.

Here's how you can do that:

Create a class on the server side which maps to the requested JSON object, e.g.

public class MyClass
{
    // The type (int or string) should probably correspond to the JSON
    public int vendorId { get; set; }
    public string businessUnit { get; set; }
    public string productSegmentId { get; set; }
    public string programId { get; set; }
    public string productManagerId { get; set; }
    public string companyIds { get; set; }
    public string expired { get; set; }
    public string requestType { get; set; }
}

Convert Request.InputStream into that type, and then you can use it.

public void ProcessRequest()
{
    System.IO.Stream body = Request.InputStream;
    System.Text.Encoding encoding = Request.ContentEncoding;
    System.IO.StreamReader reader = new System.IO.StreamReader(body, encoding);
    string json = reader.ReadToEnd();
    JavaScriptSerializer serializer = new JavaScriptSerializer();
    MyClass myclass = (MyClass)serializer.Deserialize(json, typeof(MyClass));
    int vendorId = myclass.vendorId;
    string requestType = myclass.requestType;
    // etc...
}

protected void Page_Load(object sender, EventArgs e)
{
    ProcessRequest();
}
