我一直在尝试不同的显示 PDF 的方法,目的是找到一种方法将灰色背景更改为白色。
这是一个使用对象标签的简单示例(我使用嵌入和 iframe 标签得到相同的结果):

HTML
<object data='https://dl.dropboxusercontent.com/u/58922976/test.pdf#view=FitH&scrollbar=0&toolbar=0&statusbar=0&messages=0&navpanes=0'
type='application/pdf'
width='84%'
height='110px'>
<p>It appears your Web browser is not configured to display PDF files.
No worries, just <a href='https://dl.dropboxusercontent.com/u/58922976/test.pdf'>click here to download the PDF file.</a></p>
</object>
Thanks!!
The OP Link actually now succeeds by default, here is the view of requesting no pdf where response is with image on white background

但是,通常使用深色或浅色演示文稿背景来显示图像、PowerPoint、pdf、其他视图
这完全取决于观众
This browser only opens files in external mode
Or why not rainbow friendly?
But for the answer, ask users to do it themselves
对于 Firefox 用户,有一个 hack see如何在 Firefox 中查看 pdf 文件时启用深色模式 https://stackoverflow.com/questions/61814564/how-can-i-enable-dark-mode-when-viewing-a-pdf-file-in-firefox#61814602 https://stackoverflow.com/a/74564207/10802527 https://stackoverflow.com/a/74564207/10802527
