PHP:将远程 pdf 流式传输到客户端浏览器 [英] PHP: stream remote pdf to client browser

问题描述

在外部服务上生成了一个 pdf，我想将 pdf 流式传输到我的 php 服务器中的浏览器，同时流式传输到客户端，这样我就不需要从远程文件下载 pdf 然后开始初始化下载.我只会让文件立即下载或流式传输到请求它的客户端.

there's a pdf generated on an external service and I would like to stream the pdf to the browser in my php server while streaming to client so that I don't need to download the pdf from the remote file and then start initializing download. I would just have the file immediately download or stream to the client requesting it.

推荐答案

假设生成的 pdf 在 http://bar.com/foo.pdf，你可以这样做:

Assuming that the generated pdf is in http://bar.com/foo.pdf, you could do:

  $data = file_get_contents("http://bar.com/foo.pdf");
  header("Content-type: application/octet-stream");
  header("Content-disposition: attachment;filename=YOURFILE.pdf");

  echo $data;
