如果不动手实践，总会把复杂的问题想简单。其实也不复杂，只是用得少，不熟悉。
还是这个题目，已经写到了version5.1。起初很随便地用了自己不太了解的socket通信，稀里糊涂地完成了功能。但是到后期改代码就很困难了。索性一不做二不休，改成zmq通信，毕竟用过。
但是不会用zmq进行一对多的通信，客户端开多了，总是会弄乱send和recv。只能在每个循环中，只设置一对send，recv。
本想偷懒不用正则匹配，结果偷鸡不成蚀把米，zmq混乱了。还是老老实实用正则匹配从前台获取周期。
使用zmq通信最大的感受就是，一定要弄清消息的“来龙去脉”，client和server的send和recv一定要完美匹配，才不会出错。
废话说完，上干货！
