具体代码如下所示：
public static String sendGet(String url,String param) { Hasil string = ""; coba{ String urlName = url + "?"+param;// URL U = URL baru(urlName); Koneksi URLConnection = U.openConnection(); koneksi.koneksi(); BufferedReader di = new BufferedReader(new InputStreamReader(connection.getInputStream())); garis senar; while ((baris = masuk.readLine())!= null) { hasil += baris; } masuk.tutup(); }catch(Pengecualian e){ System.out.println("Kata Halo!!"+e); } mengembalikan hasil; } public static String sendPost(String url,String param) { String result=""; coba{ URL httpurl = URL baru(url); HttpURLConnection httpConn = (HttpURLConnection)httpurl.openConnection(); httpConn.setDoOutput(benar); httpConn.setDoInput(benar); PrintWriter keluar = PrintWriter baru(httpConn.getOutputStream()); keluar.print(param); keluar.flush(); keluar.dekat(); BufferedReader di = new BufferedReader(new InputStreamReader(httpConn.getInputStream())); garis senar; while ((baris = masuk.readLine())!= null) { hasil += baris; } masuk.tutup(); }catch(Pengecualian e){ System.out.println("HaloKata!"+e); } mengembalikan hasil; }下面给大家介绍java得到GET和POST请求URL和参数列表的方法
servlet中GET请求可以通过HttpServletRequest的getRequestURL方法和getQueryString()得到完整的请求路径和请求所有参数列表,POST的需要getParameterMap()方法遍历得到,不论GET或POST都可以通过getRequestURL+getParameterMap()来得到请求完整路径
