Mi primer clase en Java , se llama DH Tools y tiene las siguientes opciones :
- Realizar una peticion GET y guardar el contenido
- Realizar una peticion POST y guardar el contenido
- Crear o escribir archivos
- Leer archivos
- Ejecutar comandos y leer su respuesta
- HTTP FingerPrinting
- Leer el codigo de respuesta de una URL
- Borrar repetidos en un ArrayList
- Cortar las URL en un ArrayList a partir del query
- Split casero xD
- Descargar archivos
- Capturar el archivo de una URL
- URI Split
- MD5 Encode
- MD5 File
- Get IP

Ejemplos de uso :Código: java
package dhtools;
import java.util.ArrayList;
import java.util.Collections;
public class Main {
public static void main(String[] args) {
DH_Tools tools = new DH_Tools();
//String codigo = tools.toma("http://localhost/");
//String codigo = tools.tomar("http://localhost/login.php", "usuario=test&password=dsdsads&control=Login");
//tools.savefile("c:/xampp/texto.txt","texto");
//String codigo = tools.read_file("c:/xampp/texto.txt");
//String codigo = tools.console("ver");
//String codigo = tools.httpfinger("http://www.petardas.com");
/*
ArrayList array = new ArrayList();
Collections.addAll(array, "http://localhost/sql.php?id=dsaadsds", "b", "http://localhost/sql.php?id=dsaadsds", "c");
ArrayList array2 = tools.repes(tools.cortar(array));
for (int i = 0; i < array2.size(); i++) {
System.out.println(array2.get(i));
}
*/
//System.out.println(tools.regex("1sadasdsa2","1","2"));
//System.out.println(tools.response_code("http://www.petardas.com/"));
/*
File savefile = new File("c:/xampp/mierda.avi");
if(tools.download("http://localhost/test.avi",savefile)) {
System.out.println("yeah");
}
*/
//System.out.println(tools.extract_file_by_url("http://localhost/dsaads/dsadsads/index.php"));
//System.out.println(tools.uri_split("http://localhost/index.php?id=dadsdsa","query"));
//System.out.println(tools.md5_encode("123"));
//System.out.println(tools.md5_file("c:\\xampp\\texto.txt"));
//System.out.println(tools.get_ip("www.petardas.com"));
}
}
Eso seria todo.
