一般用http的post，尽量不用get；
开发中一般都使用的jar包，比较成熟，方便，易用；当然了，直接用java提供的也行

以上例子中http请求了一个url：http://192.168.:8010/xxxxxxxx/sample/；
其中是用struts配置的；对应的action方法如下：
/**
* HTTP接口,
* 接收下属客户端及子管理中心上传样本,保存样本文件
*
* @return
*/
public void sampleUpload() {

//用户认证
String userName = ("userName");
String psd = ("psd");
//此处省略了用户权限认证的操作;
String md5 = ("md5");
String mac = ("mac");
String type = ("type");
String ip = ();
if ((md5) || (mac) || (type)) {
result = "Response=011;";
} else {
