java 内连
//用 java jdk URL
URL httpurl = new URL(url);
HttpURLConnection httpConn = null;
httpConn = (HttpURLConnection) httpurl.openConnection();
httpConn.setRequestMethod("POST");
httpConn.setDoOutput(true);
httpConn.setDoInput(true);
//正式连接
httpConn.getOutputStream();
/**输入参数
PrintWriter outs = new PrintWriter(httpConn.getOutputStream());
outs.print("&back_url=" + returnurl);
outs.print("&orderid=" + deposit.getOrderId());
outs.print("&bussinessid=" + SZFConstant.B_ID);
outs.print("&digestString="
+ MD5Util.MD5Encode(SZFConstant.B_ID + deposit.getOrderId()
+ SZFConstant.KEY));
outs.flush();
outs.close();
GET 就不要 说 了 url + 参数
*/
byte[] bb = new byte[httpConn.getInputStream().available()];
httpConn.getInputStream().read(bb);
//取得数据
String str = new String(bb);
