JQuery, send JSON object using GET method

I am trying to send a json object using GET method. My code:

$.ajax({
url: "/api/endpoint",
type: "GET",
data: {"sort":"date"},
contentType: "application/json",
dataType: "json",
...


However, the headers received have "Content-Length" set to zero, hence my json parser on the server doesn't read the content.

I have already tried setting content length header, but it still comes to the server as zero:

$.ajax({
url: "/api/endpoint",
headers: {"CONTENT_LENGTH",JSON.stringify({"sort":"date"}).length},
type: "GET",
data: {"sort":"date"},
contentType: "application/json",
dataType: "json",
...


Any idea how to get this working? It HAS to be GET request.

Answer

GET requests (at least usually) do not have a message body. As mentioned in the docs, jQuery appends data of GET requests to the url parameters. You should be able to read your sort parameter from there with your server application.

BTW, no user agent will allow you to set the Content-Length header - it will (and must) be done automatically depending on the sent data.
