我想捕获当前页面并将其发送到将其转换为 pdf 的应用程序。
这就是我正在使用的:
FacesContext facesContext=FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse)
facesContext.getExternalContext().getResponse();
HttpServletRequest request = (HttpServletRequest) facesContext.getExternalContext().getRequest();
// RequestPrinter.debugString();
response.reset();
// download a pdf file
response.setContentType("application/pdf");
response.setHeader("Content-Disposition","attachment;filename="+new Date().toString()+".pdf");
prince.setVerbose(true);
prince.setLog(logFile);
try{
//getPath() to the page the user is currently on
URL pagePath=new URL(this.getPath());
URLConnection urlConnection = pagePath.openConnection();
urlConnection.setDoOutput(true);
int length = urlConnection.getContentLength();
//Lets use inputStream
BufferedInputStream bis=new BufferedInputStream(urlConnection.getInputStream());
response.setContentLength(length);
//this.getPageUsingJSoup().data().getBytes();
//call prince and pass params for inputstream outputStream
prince.convert(bis,response.getOutputStream());
urlConnection.getInputStream().close();
}catch(MalformedURLException mu){
mu.printStackTrace();
}
catch(IOException ioe){
ioe.printStackTrace();
}
facesContext.responseComplete();
由于网站需要认证,所以生成的pdf就是登录错误页面。
有没有办法捕获使用当前用户会话的页面内容?
先感谢您。
