HttpServletRequest得到请求内容

HttpServletRequest得到请求内容的方法是：

　　|--request.getInputStream();

InputStream in = request.getInputStream();

byte[] buf = new byte[1024];

int len = 0;

while((len = in.read(buf)!=-1){

　　String str = new String(buf, 0, len);

}

//char c =(char)in.read();// in.read()返回的是整型的Asscll码
