Aspectj：从 HttpServletRresponse 获取响应正文（HTML 文本）

Question

我正在尝试使用 aspectJ 来拦截 HttpServlet.do*(request, response) 并获取 HTML 文本（需要提取标题并将 html 存储到文件中）。

一旦我引用了 HttpServletResponse，访问响应正文（html 文本）的最佳方式是什么？

这是我的凝视代码。

public aspect HttpRequestHandlerAspect {

pointcut getRequest(HttpServletRequest request, HttpServletResponse response) 
    : execution(protected * javax.servlet.http.HttpServlet.*(HttpServletRequest, HttpServletResponse))  
    && args(request, response);

  Object around(HttpServletRequest request, HttpServletResponse response) : getRequest(request, response) {
      Object ret = proceed(request, response);
              // now how do I access the HTML response text ( and get the title of the page) in here?

    }
}

Answer 1

这可能不是您问题的准确答案，但请尝试按照此处的建议提取回复：How can I read an HttpServletReponses output stream? 您不必创建过滤器，只需传递给您的 HttpServletResponseWrapper

继续（请求，包装器）。

Object around(HttpServletRequest request, HttpServletResponse response): getRequest(request, response) {
    MyHttpServletResponseWrapper wrapper = new MyHttpServletResponseWrapper(response);
    Object ret = proceed(request, wrapper);
    // The MyHttpServletReponseWrapper class captures everything and doesn't forward to the original stream, so we have to do this
    response.getWriter().write(wrapper.toString());
    // use wrapper.toString() to access response
}
