Hi,

You have to create a Dictionary and call an other constructor of WWW class. To get your json (i use miniJson library, you can find many json parser for C# on internet) value :

         var dict = Json.Deserialize(get_data) as IDictionary;
 

     Dictionary<string,string> postParam = new Dictionary<string, string>();
     postParam.Add ("param", "value");

Example :

         WWWForm form = new WWWForm();
         foreach(KeyValuePair<String,String> post_arg in post)
         {
             form.AddField(post_arg.Key, post_arg.Value);
             Debug.Log(post_arg.Key);
         }
         WWW www = new WWW(url, form);

I've done for doing this below. Let's go : ==>

using UnityEngine;

using UnityEngine.UI;

using System.Collections;

using System.Collections.Generic;

public class btnGetData : MonoBehaviour {

 void Start()
 {
     gameObject.GetComponent<Button>().onClick.AddListener(TaskOnClick);
 }
 IEnumerator WaitForWWW(WWW www)
 {
     yield return www;
    
     
     string txt = "";

     if (string.IsNullOrEmpty(www.error))
         txt = www.text;  //text of success
     else
         txt = www.error;  //error

     GameObject.Find("Txtdemo").GetComponent<Text>().text =  "++++++\n\n" + txt;
 }

 void TaskOnClick()
 {
     try
     {
         GameObject.Find("Txtdemo").GetComponent<Text>().text = "starting..";   

         string ourPostData = "{\"plan\":\"TESTA02\"";

         Dictionary<string,string> headers = new Dictionary<string, string>();
         headers.Add("Content-Type", "application/json");

         //byte[] b = System.Text.Encoding.UTF8.GetBytes();
         byte[] pData = System.Text.Encoding.ASCII.GetBytes(ourPostData.ToCharArray());


         ///POST by IIS hosting...
         WWW api = new WWW("http://192.168.1.120/si_aoi/api/total", pData, headers);


         ///GET by IIS hosting...
         ///WWW api = new WWW("http://192.168.1.120/si_aoi/api/total?dynamix={\"plan\":\"TESTA02\"");

         StartCoroutine(WaitForWWW(api));

     }
     catch (UnityException ex) { Debug.Log(ex.Message); }
 }
 

}
