Dusan Zatkovsky napsal(a):
S tym servletom je to vyborny napad, akurat vobec netusim, ako to naprogramovat ( web je moja slaba stranka ) :)
Tak tady to je :-)
public class PutServlet extends HttpServlet {
@Override
protected void doPut(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
ServletInputStream in = request.getInputStream();
byte[] buffer = new byte[4096];
BufferedOutputStream out = new BufferedOutputStream(new
FileOutputStream("/tmp/soubor"));
int n;
while((n=in.read(buffer))!=-1) {
out.write(buffer,0,n);
}
out.close();
in.close();
response.setStatus(HttpServletResponse.SC_OK);
}
}
a namapovat ho ve web.xml třeba takto:
<servlet>
<servlet-name>PutServlet</servlet-name>
<servlet-class>cz.makub.PutServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>PutServlet</servlet-name>
<url-pattern>/put/*</url-pattern>
</servlet-mapping>
a klient může použít HTTP klienta z JDK:
public class PutClient {
public static void main(String[] args) throws IOException {
HttpURLConnection uc = (HttpURLConnection) new
URL("http://localhost:8080/putapp/put/file";).openConnection();
uc.setRequestMethod("PUT");
uc.setDoOutput(true);
BufferedInputStream in = new BufferedInputStream(
new FileInputStream("veliky_soubor"));
byte[] buffer = new byte[4096];
int n;
OutputStream out = uc.getOutputStream();
while ((n = in.read(buffer)) != -1) {
out.write(buffer, 0, n);
}
in.close();
out.close();
int responseCode = uc.getResponseCode();
System.out.println("responseCode = " + responseCode);
}
}
Samozřejmě čtení a ukládání souborů je třeba předělat
na něco reálného.
