在http请求中，有Header和Body之分，读取header使用request.getHeader("...");

读取Body使用request.getReader()，但getReader获取的是BufferedReader，需要把它转换成字符串，下面是转换的方法。

public class TestController { @RequestMapping("/a") protected void doPost(HttpServletRequest request, HttpServletResponse response, BufferedReader br) throws ServletException, IOException { //Header部分 System.out.print(request.getHeaderNames()); Enumeration<?> enum1 = request.getHeaderNames(); while (enum1.hasMoreElements()) { String key = (String) enum1.nextElement(); String value = request.getHeader(key); System.out.println(key + "t" + value); } //body部分 String inputLine; String str = ""; try { while ((inputLine = br.readLine()) != null) { str += inputLine; } br.close(); } catch (IOException e) { System.out.println("IOException: " + e); } System.out.println("str:" + str); }
