Java后台基于POST获取JSON格式数据

String s ="";
InputStream in = null;
BufferedInputStream bin = null;
try{
  in = request.getInputStream();
  bin = new BufferedInputStream(in);
  int len = 0;
  byte[] b = new byte[1024];
  while( (len = bin.read(b)) != -1){
    s += new String(b,0,len);
  }
} catch (IOException e) {
  e.printStackTrace();
}finally{
  try{
    bin.close();
  }catch (IOException e) {
    e.printStackTrace();
  }
   try{
    in.close();
  }catch (IOException e) {
    e.printStackTrace();
  }
}//最后根据取到的字符串适用JSONUtil工具将其转换成相应的对象（根据JSON工具类进行调整）
类名称 对象名 = JSONUtil.jsonToobj(s , "类名称.clsss");

InputStream in = req.getInputStream();
BufferedReader bin = new BufferedReader(new InputStreamReader(in, "utf-8"));
String line = null;
StringBuffer content = new StringBuffer();
while ((line = bin.readLine()) != null) {
     content.append(line);
  }
