如何读取HttpServletReponses输出流？

将此添加到过滤器java文件。

static class MyHttpServletResponseWrapper   extends HttpServletResponseWrapper {  private StringWriter sw = new StringWriter(BUFFER_SIZE);  public MyHttpServletResponseWrapper(HttpServletResponse response) {    super(response);  }  public PrintWriter getWriter() throws IOException {    return new PrintWriter(sw);  }  public ServletOutputStream getOutputStream() throws IOException {    throw new UnsupportedOperationException();  }  public String toString() {    return sw.toString();  }}

使用以下代码：

HttpServletResponse httpResponse = (HttpServletResponse) response;MyHttpServletResponseWrapper wrapper =   new MyHttpServletResponseWrapper(httpResponse);chain.doFilter(request, wrapper);String content = wrapper.toString();

现在，content变量具有输出流。您也可以对二进制内容执行此操作。
