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");
