1、发送给服务器端的信息，因为图片是选择的在web端只提供了50个表情选择，所以将 #哈哈# ，凡是# #包裹的内容转化成对应的unicode编码， 比如U+1F603。每一个对应起来，这一点比较麻烦。
2、服务器发过来的信息 将里面U+1f603 这种 u+开头的转化成<span class="emoji emoji1f603 "></span>，再根据emoji.js emoji.css emoji.png这三个文件 显示出图片。
3、代码链接：链接：https://pan.baidu.com/s/1nsuzW7o7_CaaHLWXgdsP2Q 密码：br1u；运行里面的test.html可看效果。
