控制端將鼠標(biāo)事件傳遞到服務(wù)端
服務(wù)端拿到鼠標(biāo)事件之后傳輸?shù)娇蛻舳?/strong>
客戶端拿到鼠標(biāo)事件之后，通過robot類即可完成，并且截屏將圖片發(fā)給服務(wù)器，服務(wù)器再發(fā)給控制端
被我簡(jiǎn)化之后得到

//先介紹一下robot類的簡(jiǎn)單使用import java.awt.awtexception;import java.awt.robot;import java.awt.event.inputevent;/** * 使用robot * @author 啞元 * */public class robottest { public static void main(string[] args) throws awtexception { robot r = new robot(); r.mousemove(300, 500);//鼠標(biāo)移動(dòng) r.mousepress(inputevent.button1_mask ); //鼠標(biāo)按下 r.mouserelease(inputevent.button1_mask);//鼠標(biāo)松開 r.keypress((int)'a'); //鍵盤按下 (int)'a'表示將a轉(zhuǎn)換成鍵盤對(duì)應(yīng)的key r.keyrelease((int)'a'); //鍵盤松開 }}//屏幕抓取import java.awt.awtexception;import java.awt.rectangle;import java.awt.robot;import java.awt.image.bufferedimage;import javax.swing.imageicon;import javax.swing.jframe;import javax.swing.jlabel;import javax.swing.windowconstants;/** * 抓取本地桌面圖片 * @author 啞元 * */public class screentest { public static void main(string[] args) throws awtexception, interruptedexception { robot robot = new robot(); jframe jframe = new jframe(); jframe.setsize(1200, 700); jlabel label = new jlabel(); jframe.add(label); //四個(gè)參數(shù)x y width height jframe.setvisible(true); jframe.setdefaultcloseoperation(windowconstants.exit_on_close ); //構(gòu)建一個(gè)死循環(huán)動(dòng)態(tài)截取 while(true){ bufferedimage image = robot.createscreencapture(new rectangle(0,0,1366,768));//截取屏幕 label.seticon(new imageicon(image)); thread.sleep(50); } }} |
//遠(yuǎn)程控制原理講解
//分為server端和client端，
//原本server端只作為轉(zhuǎn)發(fā)，作為演示，就不寫轉(zhuǎn)發(fā)
//也就是client端控制server端e
/**
* 這里我采用的是，在client端也就是操控端，接收到server端發(fā)送過來(lái)的screen之后，然后發(fā)送鼠標(biāo)事件過去
* 然后再用robot處理
* 傳輸方式用socket+io即可處理
* 屏幕截取和圖片壓縮采用了robot的屏幕截取功能和jdk自帶的圖片編碼器，將其轉(zhuǎn)換成一個(gè)字節(jié)數(shù)組
* 發(fā)送給server端之后，robot通過io+socket可以直接拿到object對(duì)象，強(qiáng)制轉(zhuǎn)換成inputevent(keyevent和mouseevent都繼承)之后
* 通過判斷event類型，分別處理即可，這里在服務(wù)端需要用到兩個(gè)線程，一個(gè)是屏幕截取和發(fā)送給客戶端，一個(gè)是用來(lái)監(jiān)聽客戶端
* 傳遞過來(lái)的事件
