[英]Developing an SMS Sending Application using Java Swing
我在課堂上有2個功能:
login()
登錄到站點
Send_Sms()
發送短信
在這里,我正在考慮為函數放置2個線程,以便可以通過某種方式控制Send_Sms函數的Send_Sms
,以便在login()
成功完成后開始發送短信,否則程序將無法工作。
到目前為止,這是我所做的:
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.Writer;
import java.util.logging.Level;
import java.util.logging.Logger;
public class RunThreads extends Thread
{
public void Login(String username,String password)
{
try
{
// creates the batch file for Logging into abc.com server
Writer output = null;
String UserAgent = "Mozilla/5.0 (Windows NT 5.1;KM:10.0.2)";
String postdata = "\"" + "username="+username+ "&password=" + password + "&button=Login" + "\"";
String MainStream = "c:\\wget.exe --output-document=login.html --user-agent=" + "\"" + UserAgent + "\"" + " --max-redirect=10 --cookies=on --keep-session-cookies --save-cookies=cookie.txt --post-data " + postdata + " http://www.abc.com/Login1.action;";
File file = new File("login.bat");
output = new BufferedWriter(new FileWriter(file));
output.write(MainStream);
output.close();
Runtime.getRuntime().exec("cmd /c start login.bat");
}
catch (IOException ex)
{
Logger.getLogger(Save_Credentials.class.getName()).log(Level.SEVERE, null, ex);
}
}
public void SendSms(String mobno,String content) throws IOException
{
Writer output = null;
String UserAgent = "Mozilla/5.0 (Windows NT 5.1;KM:10.0.2)";
String MainStream = "c:\\wget.exe --output-document=quicksms.html --user-agent=" + "\"" + UserAgent + "\"" + " --referer=http://www.abc.com/jsp/SMS.jsp --cookies=on --keep-session-cookies --load-cookies=cookie.txt --save-cookies=cookie.txt --post-data "+"\""+"&HiddenAction=instantsms&catnamedis=Birthday&Action=gstahsbdf5346g&chkall=on&MobNo="+mobno+"&textArea="+content+"\""+" http://www.abc.com/quicksms.action;";
File file = new File("SendSms.bat");
output = new BufferedWriter(new FileWriter(file));
output.write(MainStream);
output.close();
Runtime.getRuntime().exec("cmd /c start SendSms.bat");
}
public static void main(String[] args)
{
}
}
如您自己所言,如果登錄失敗,將無法發送短信,因此:
可以通過以下方式控制Send_Sms函數的執行權:成功完成login()之后,它將開始發送短信,否則程序將無法工作。
那么這兩個任務是順序耦合的,這意味着在不同線程上並行執行它們是沒有意義的。 只需在單個線程上按順序執行它們即可。
