Hi,

we are doing this but we are consuming within same application so for us there are no issues using POST sling servlet.

But if you are exposing json over post you have to care of a lot of security like enable filter to allow post

      @sanjay_bangar 

      how is the Json data generated? is it dynamically generated or json stored in AEM?

      Are you trying to call the servlet upon any form submission? 

       

      you can try making ajax calls to the servlet and pass json data to the servlet post method.

          When doing a ajax call use something like below

           

          var square = {};

          square.length = 10;

          square.width = 10;

          $.ajax(

          url: url,

          data: JSON.stringify(square),

          dataType: “json”

          contentType: “application/json”,

          Type: “POST”

          );

           

          while reading in servlet you can use like below:

           

          String requestBody = request.getReader().lines().collect(Collectirs.joining());


          you can use any Utils class to convert from string to json or java bean.

           

          Thanks!
