Unity之获取资源包的路径

先从缓存中获取，如果获取不到，则从包中获取。

如下：

        public static string GetAssetBundlePath(string path)
        {
            // 先尝试从 persist 目录加载
            if (GameConfig.HotPatching)
            {
                getPathResult.Length = 0;
                getPathResult.Append(BundleDownloader.Folder);
                getPathResult.Append("/");
                getPathResult.Append(path);
                tmpPath = getPathResult.ToString();
                if (File.Exists(tmpPath))
                {
                    getPathResult.Length = 0;
                    getPathResult.Append("file:///");
                    getPathResult.Append(BundleDownloader.Folder);
                    getPathResult.Append("/");
                    getPathResult.Append(path);
                    tmpPath = getPathResult.ToString();
                    return tmpPath;
                }
            }

#if UNITY_EDITOR || UNITY_STANDALONE_WIN
            getPathResult.Length = 0;
            getPathResult.Append("file://");
            getPathResult.Append(Application.streamingAssetsPath);
            getPathResult.Append("/");
            getPathResult.Append(path);
            tmpPath = getPathResult.ToString();
#elif UNITY_IOS
            getPathResult.Length = 0;
            getPathResult.Append("file://");
            getPathResult.Append(Application.dataPath);
            getPathResult.Append("/Raw/");
            getPathResult.Append(path);
            tmpPath = getPathResult.ToString();
#elif UNITY_ANDROID
            getPathResult.Length = 0;
            getPathResult.Append("jar:file://");
            getPathResult.Append(Application.dataPath);
            getPathResult.Append("!/assets/");
            getPathResult.Append(path);
            tmpPath = getPathResult.ToString();
#endif
            return tmpPath;
        }
