推荐答案

然后阅读PDF文件内容并显示在div或某个容器中的网页。

Then read the PDF file contents and show in the Web Page in a div or some container.

如果是这种情况，则无法将PDF文件发送到客户端。您的服务器端代码必须拍摄PDF的每个页面的图片（呈现为图像）并发送图像以显示在客户端上。

If that's the case you can't send the PDF file to the client. Your server-side code has to take a "picture" of each page of the PDF (rendered as an image) and send the image to be displayed on the client.
