微信公众号和web项目聊天表情转化

本博文主要陈述，当项目中引入微信公众号聊天业务时，在进行聊天时，用户表情的转化，

分为：微信表情转化为项目中聊天表情的格式和项目表情转化成微信格式表情。

定义表情正则表达式

private static String regex = "/::\\)|/::~|/::B|/::\\||/:8-\\)|/::<|/::\\$|/::X|/::Z|/::'\\(|/::-\\||/::@|/::P|/::D|/::O|/::\\(|/::\\+|/:--b|/::Q|/::T|/:,@P|/:,@-D|/::d|/:,@o|/::g|/:\\|-\\)|/::!|/::L|/::>|/::,@|/:,@f|/::-S|/:\\?|/:,@x|/:,@@|/::8|/:,@!|/:!!!|/:xx|/:bye|/:wipe|/:dig|/:handclap|/:&-\\(|/:B-\\)|/:<@|/:@>|/::-O|/:>-\\||/:P-\\(|/::'\\||/:X-\\)|/::\\*|/:@x|/:8\\*|/:pd|/:<W>|/:beer|/:basketb|/:oo|/:coffee|/:eat|/:pig|/:rose|/:fade|/:showlove|/:heart|/:break|/:cake|/:li|/:bome|/:kn|/:footb|/:ladybug|/:shit|/:moon|/:sun|/:gift|/:hug|/:strong|/:weak|/:share|/:v|/:@\\)|/:jj|/:@@|/:bad|/:lvu|/:no|/:ok|/:love|/:<L>|/:jump|/:shake|/:<O>|/:circle|/:kotow|/:turn|/:skip|/:oY|/:#-0|/:hiphot|/:kiss|/:<&|/:&>";

微信表情内容转成项目聊天表情格式

public static String wechatToUCKeFuface(String content){if(content==null){return null;}logger.info("打印微信表情==========>"+content);StringBuffer sb = new StringBuffer();// 发送内容和pattern 进行匹配Matcher m =  pattern.matcher(content);while(m.find()){//此里面的可以替换为配置String faceStr = m.group();System.out.println("正则表达式匹配后的数据：faceStr =[{}]"+faceStr);// 从定义的静态变量表情中根据 key 查找 valueString face = emotions.get(faceStr);System.out.println("获取表情：face =[{}]"+face);if(face!=null){m.appendReplacement(sb, "<img src=\"/js/kindeditor/plugins/emoticons/images/"+emotions.get(m.group())+".gif\" border=\"0\" alt=\"\" />");System.out.println("打印微信表情替换为配置==========>"+sb+"=============");}else{System.out.println("wechatToUCKeFuface not find:{}"+m.group());//logger.info("打印微信表情替换为配置2==========>"+sb+"=============");}}m.appendTail(sb);System.out.println("打印微信表情end==========>"+sb.toString()+"=============");return sb.toString();}
