获取方式一
InputStream in = request.getInputStream();
int len = 0;
byte buffer[] = new byte[1024];
while((len = in.read(buffer)) > 0) {
System.out.println(len);
System.out.println(new String(buffer,0,len));
}
获取方式二
String value = request.getParameter("username");
if(value != null && !value.trim().equals("")){
System.out.println(value);
}
获取方式三
Enumeration e = request.getParameterNames();
while(e.hasMoreElements()){
String name = (String)e.nextElement();
value = request.getParameter(name);
System.out.println(name + ":" + value);
}
获取方式四
String[] values = request.getParameterValues("username");
for(int i=0;values !=null && i < values.length;i++){
System.out.println(values[i]);
}
获取方式五
Map map = request.getParameterMap();
User user = new User();
BeanUtils.populate(user, map);
... 这里引用了 commons-beanutils-1.8.0.jar 和 commons-logging.jar 包
public class User{
public string[] getUsername(){...}
public string[] getPassword(){...}
}
