服務器代碼:
LoginServlet:
package com;

復制代碼 代碼如下:

import java.io.ByteArrayOutputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

// 得到客戶端傳入的數據(用戶名和密碼)

{
// 響應數據
dos.writeUTF("true");
} else
{
// 響應數據
dos.writeUTF("false");
}
//
byte[] data = baos.toByteArray();
// 設置服務器響應參數
response.setStatus(HttpServletResponse.SC_OK);
response.setContentLength(data.length);
response.setContentType("application/octet-stream");
OutputStream os = response.getOutputStream();
os.write(data);
os.close();
}
