Post Raw Data In Request Body

[Dave]

I'm trying to access a REST service that expects raw XML to be POSTed in the body of the request. I read in the forums here that the transport property of the Data Source works via the jQuery.ajax() function, so I should be able to do something like this:

var ds = new kendo.data.DataSource({

transport: {

read: {

url: "...",

dataType: "xml",

cache: false,

contentType: "application/xml",

type: "POST",

data: "<Test></Test>"

}

}

});

In Fiddler, I can see that the Content-Type of the request is indeed getting set to "application/xml". However, the body is totally empty. If I change the data parameter to use a key-value structure, then it does pass the key-value in the body of the request. I can't figure out why sending raw content in the body isn't working - does Kendo pre-process the data property in some way to disallow this kind of use?

Hello David,

The dataSource is extending that data parameter via jQuery.extend() in order to append the information about paging, sorting, etc. When you extend a string, the original information is lost, that is why you should define the data parameter as an object. This behaviour could be observed without using Kendo: 

var foo = "bar";
$.extend(foo, {bar: 1}); //returns {"bar":1}

var bar = { foo: "bar" };
$.extend(bar, { bar: 1 }); //returns {"foo":"bar","bar":1}

I hope this information helps.

Hi Alexander,

So in David's case how would he address the issue? I am facing a similar situation and would like to see how to do a direct post in body of a datasource read.

I have seen another post here explaining to define the data parameter as

data: { testxml: escape('<test></test>')} 

This means the server side will have to accept the testxml field and extract the data out of that?
Is there another way to do this?

Thanks

I've got the same question for you. I need the data source to provide the same request body format as the jquery mehod below. In the method below, data is simply set to a string and the request body is that string. 

                $.ajax({
                    contentType: "application/json; charset=utf-8",
                    type: 'POST',
                    url: "/myurl/GetData",
                    data: "21",
                    success: function (jqXHR) { processSuccess(jqXHR);},
                    dataType: "json"
                });

I have not been able to figure out how to kendo ui datasource to output a string I provide. My understanding is that the kendo ui datasource data extends the data object, the output is then put in a querystring format  "myvar=21" etc.. 

Thanks.
