網(wǎng)上好多例子都是群發(fā)的，本文實(shí)現(xiàn)一對(duì)一的發(fā)送，給指定客戶端進(jìn)行消息推送
1、本文使用到netty-socketio開(kāi)源庫(kù)，以及mysql，所以首先在pom.xml中添加相應(yīng)的依賴庫(kù)

9、工程結(jié)構(gòu)
10、運(yùn)行測(cè)試
1） 添加基礎(chǔ)數(shù)據(jù)，數(shù)據(jù)庫(kù)中預(yù)置3個(gè)客戶端testclient1,testclient2,testclient3
2) 創(chuàng)建客戶端文件index.html,index2.html,index3.html分別代表testclient1 testclient2 testclient3三個(gè)用戶
本文直接修改的https://github.com/mrniko/netty-socketio-demo/tree/master/client 中的index.html文件
其中clientid為發(fā)送者id， targetclientid為目標(biāo)方id，本文簡(jiǎn)單的將發(fā)送方和接收方寫死在html文件中
使用 以下代碼進(jìn)行連接

io.connect('http://localhost:8081?clientid='+clientid); |

3、本例測(cè)試時(shí)
testclient1 發(fā)送消息給 testclient2
testclient2 發(fā)送消息給 testclient1
testclient3發(fā)送消息給testclient1
運(yùn)行結(jié)果如下
以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持服務(wù)器之家。
