HttpServletRequest 的使用

1. 从HttpServletRequest中读取请求参数

InputStream inStream = request.getInputStream();

ByteArrayOutputStream outSteam = new ByteArrayOutputStream();

byte[] buffer = new byte[1024];

int len = 0;

while ((len = inStream.read(buffer)) != -1) {

　　outSteam.write(buffer, 0, len);

}

System.out.println("~~~~~~~~~~~~~~~~付款成功~~~~~~~~~");

outSteam.close();

inStream.close();

String result  = new String(outSteam.toByteArray(),"utf-8");
