public byte[] data;


(Read Only) The raw data to pass as the POST request body when sending the form.

Usually, you just pass the WWWForm object directly to the WWW constructor, but you will need this variable if you want to change the request headers sent to the web server.

See Also: headers variable.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class ExampleClass : MonoBehaviour { IEnumerator Start() { WWWForm form = new WWWForm(); form.AddField( "name", "value" ); Dictionary<string, string> headers = form.headers; byte[] rawData =; string url = "";

// Add a custom header to the request. // In this case a basic authentication to access a password protected resource. headers["Authorization"] = "Basic " + System.Convert.ToBase64String( System.Text.Encoding.ASCII.GetBytes("username:password"));

// Post a request to an URL with our custom headers using (WWW www = new WWW(url, rawData, headers)) { yield return www; //.. process results from WWW request here... } } }
