这是一个用Lua编写的WebSprite类，用于处理以URL形式提供的头像。该类创建一个精灵节点，并根据传入的宽度和高度参数调整大小。它会检查本地缓存中是否存在图片文件，如果存在则直接加载，否则从网络下载并在下载完成后显示。

-- 获取头像的地址
local sHeadUrl = self._ResultInfoTable.tbUserPoint[tostring(realSeat)].sHeadUrl;
if sHeadUrl and sHeadUrl ~= "" then
--创建头像
local headSp = WebSprite.create(sHeadUrl, 60, 60);
headNode:addChild(headSp);
else
-- 创建默认头像
local defaultHeadSp = cc.Sprite:create("这里使用默认头像");
defaultHeadSp:setPosition(0, -5);
headNode:addChild(defaultHeadSp);

end
