spring接到浏览器传来的post请求 所传进来的参数都在request里

1  @RequestMapping(value = PROXY_URL, method = RequestMethod.POST, produces = PRODUCES)2     public Object proxy(final HttpServletRequest request, final HttpServletResponse response) {3 　　　　　　String json = "";4                 json = new String(readInputStream(request.getInputStream()), "UTF-8");

5     }

此时debug查看request.getInputStream()的值是全部请求信息 但是并非我们想要是参数

 

 所以我们要对结果解析

readInputSream()是解析方法

1     public static byte[] readInputStream(InputStream inStream) throws Exception { 2         ByteArrayOutputStream outSteam = new ByteArrayOutputStream(); 3         byte[] buffer = new byte[1024]; 4         boolean var3 = false; 5  6         int len; 7         while((len = inStream.read(buffer)) != -1) { 8             outSteam.write(buffer, 0, len); 9         }10 11         outSteam.close();12         inStream.close();13         return outSteam.toByteArray();14     }

inStream.read(buffer)读取数据赋值给buffer

 

outSteam的结果就是我们想要的数据了

注意 这里的json格式的数据是前端定义好传进来的 和后台对io流解析无关
