小女子求高手改一下基礎代碼 www 改 UnityWebRequest，高手請進

求大神把下面這個代碼改成 UnityWebRequest 請求


IEnumerator Get(string url, string auth, string json) 
{
Dictionary<string,string> header = new Dictionary<string, string>();
       byte[] postBytes;
 
    header.Add("Content-Type", "application/json");//添加header
    if（auth != null）
    {
    header.Add("Authorization",auth);
    }
    
    if(json != null)
    {
        //POST
    //將資料轉換成json資料流
    postBytes = System.Text.Encoding.UTF8.GetBytes(json);
}
else
{
        //GET
//此案例不需要json資料所以為null
postBytes=null;
}
 
    WWW www = new WWW (url,postBytes,m_dir);
    yield return www;
 
    if (www.error != null) 
    {
        Debug.Log("error is :"+ www.error);
    } 
    else 
    {
        Debug.Log("request result :" + www.text);
    }
 
}
