FairyGUI裝載器加載網絡圖片

主要是實現顯示網絡頭像。

 

只要擴展裝載器就可以了。

 

using FairyGUI;
using UnityEngine;
using Api;
using System.IO;

namespace Tools
{
    public class HttpLoader : GLoader
    {
        protected override void LoadExternal()
        {
            // 這里主要是區分在家本地資源和網絡資源，
            // 因為我的網絡url是 /static開頭的，所以在這里做個判斷。
            // 如果不判斷，本地資源就無法加載，導致場景無法正確加載
            if (!url.StartsWith("/static/"))
            {
                base.LoadExternal();
                return;
            }

            Client client = new Client();
            byte[] imgBytes = client.GetBytes(url);
            Texture2D tex = new Texture2D(0, 0);
            tex.LoadImage(imgBytes);
            tex.Apply();
            if (tex != null)
                onExternalLoadSuccess(new NTexture(tex));
            else
                onExternalLoadFailed();
        }
    }
}

 

然后調用下方的方法，最好是在第一個場景的構造方法中調用。

UIObjectFactory.SetLoaderExtension(typeof(Tools.HttpLoader));

 

最后，獲取設計的界面中的裝載器，設置url即可

mainUI.GetChild("imgAvatar").asLoader.url = "/static" + j["data"]["user"]["avatar"].str;

unity中運行效果

 

Client類自己隨便封裝的http請求類，也順便發一下。

namespace Api
{
    using System.Net.Http;
    using System;
    using System.Collections.Generic;
    public class Client : HttpClient
    {
        private string baseUrl = "http://192.168.1.105";
        public Client()
        {
            this.DefaultRequestHeaders.Add("user-agent", "game");
        }

        ~Client()
        {
            this.Dispose();
        }

        public Client(string token)
        {
            this.DefaultRequestHeaders.Add("user-agent", "game");
            if (token != "")
            {
                this.DefaultRequestHeaders.Add("token", token);
            }


        }

        /// <summary>
        /// Get請求返回Response
        /// </summary>
        /// <param name="url">要請求的地址</param>
        /// <returns>返回response</returns>
        public HttpResponseMessage Get(string url)
        {
            return this.GetAsync(this.baseUrl + url).Result;
        }

        /// <summary>
        /// get請求獲取返回的內容
        /// </summary>
        /// <param name="url">要請求的地址</param>
        /// <returns>返回網頁內容</returns>
        public string GetContent(string url)
        {
            return this.Get(url).Content.ReadAsStringAsync().Result;
        }

        public byte[] GetBytes(string url)
        {
            return this.Get(url).Content.ReadAsByteArrayAsync().Result;
        }

        public HttpResponseMessage Post(string url, List<KeyValuePair<string, string>> paramList)
        {
            return this.PostAsync(new Uri(this.baseUrl + url), new FormUrlEncodedContent(paramList)).Result;
        }

        public string PostContent(string url, List<KeyValuePair<string, string>> paramList)
        {
            return this.Post(url, paramList).Content.ReadAsStringAsync().Result;
        }

        public HttpResponseMessage Put(string url, List<KeyValuePair<string, string>> paramList)
        {
            return this.PutAsync(new Uri(this.baseUrl + url), new FormUrlEncodedContent(paramList)).Result;
        }

        public string PutContent(string url, List<KeyValuePair<string, string>> paramList)
        {
            return this.Put(url, paramList).Content.ReadAsStringAsync().Result;
        }

        public HttpResponseMessage Del(string url)
        {
            return this.DeleteAsync(this.baseUrl + url).Result;
        }

        public string DelContent(string url)
        {
            return this.Del(url).Content.ReadAsStringAsync().Result;
        }

    }
}
