Question

I want to pass three field in wwwform, which contain two single value and a json array.
Here is my Json:
{
"Fname":"Abc",
"Lname":"Xyz",
"Marks": [{"MarksA":"23","MarksB":"65" },
{"MarksA":"24","MarksB":"56" } ]
}
My current code is
void Start()
{
WWWForm form = new WWWForm();
form.AddField("Fname", "Abc");
form.AddField("Lname", "Xyz");
//passing the array as string
string Mymarks = "[{\"MarksA\":\"23\",\"MarksB\":\"65\" },{\"MarksA\":\"24\",\"MarksB\":\"56\" } ]";
form.AddField("Marks", Mymarks);
WWW www = new WWW("Urltoservice", form);
StartCoroutine("PostRequest", www);
}
IEnumerator PostRequest(WWW www)
{
yield return www;
if (www.error == null)
{
Debug.Log("Session Saved");
}
else
{
Debug.Log("WWW Error: " + www.error);
}
}
But I am getting 500 internal server Error. Please help me.

Answer 1

Try using WWW instead of WWWForm
using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System.Collections.Generic;
public class SendData : MonoBehaviour {
void Start()
{
gameObject.GetComponent<Button>().onClick.AddListener(SendOnClick);
}
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("TextDemo").GetComponent<Text>().text = "--------\n\n" + txt;
}
void SendOnClick()
{
try
{
GameObject.Find("TextDemo").GetComponent<Text>().text = "Starting..";
string ourPostData = "{\"MarksA\":\"23\",\"MarksB\":\"65\" },{\"MarksA\":\"24\",\"MarksB\":\"56\" }";
Dictionary<string,string> headers = new Dictionary<string, string>();
headers.Add("Content-Type", "application/json");
byte[] jData = System.Text.Encoding.ASCII.GetBytes(ourPostData.ToCharArray());
WWW api = new WWW("YOUR URL", jData, headers);
StartCoroutine(WaitForWWW(api));
}
catch (UnityException ex) { Debug.Log(ex.message); }
}
}
