【Java】java获取request body
//方式一 public static String ReadAsChars(HttpServletRequest request) { BufferedReader br = null; StringBuilder sb = new StringBuilder(""); try { br = request.getReader(); String str; while ((str = br.readLine()) != null) { sb.append(str); } br.close(); } catch (IOException e) { e.printStackTrace(); } finally { if (null != br) { try { br.close(); } catch (IOException e) { e.printStackTrace(); } } } return sb.toString(); } // 方法二 public static void ReadAsChars2(HttpServletRequest request) { InputStream is = null; try { is = request.getInputStream(); StringBuilder sb = new StringBuilder(); byte[] b = new byte[4096]; for (int n; (n = is.read(b)) != -1;) { sb.append(new String(b, 0, n)); } } catch (IOException e) { e.printStackTrace(); } finally { if (null != is) { try { is.close(); } catch (IOException e) { e.printStackTrace(); } } } } // 二进制读取 public static byte[] readAsBytes(HttpServletRequest request) { int len = request.getContentLength(); byte[] buffer = new byte[len]; ServletInputStream in = null; try { in = request.getInputStream(); in.read(buffer, 0, len); in.close(); } catch (IOException e) { e.printStackTrace(); } finally { if (null != in) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } } return buffer; } }
