Unity3D:HTTP请求模块

先上接口

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

namespace YDB.Http
{
    public interface IHttp
    {
        /// 

        /// Get
        /// 
        /// 回调
        /// 地址
        void Get(Action<string> callback,string url);
        /// 

        /// Get
        /// 
        /// 回调
        /// 地址
        void Get(Action<byte[]> callback, string url);
        /// 

        /// Get
        /// 
        /// 回调
        /// 地址
        void Get(Action<Texture> callback, string url);
        /// 

        /// Post
        /// 
        /// 参数
        /// 地址
        void Post(Dictionary<string, string> parameters, string url);
    }
}
