在 Heroku 上托管的 Flask 应用程序中渲染散景图
Render Bokeh plots in Flask app hosted on Heroku
我有以下由 Heroku 在 https://macabre-spirit-1593.herokuapp.com/1/ 提供的基本散景图。当我在本地 运行 这个应用程序，或者保存 Heroku 页面并在本地打开它时，该图出现，但是当我在 Heroku 上查看该页面时，该图不存在。为什么从 Heroku 服务时没有出现情节？

Heroku 页面通过 HTTPS 提供。页面上的资源被硬编码为通过 HTTP 提供服务。出于安全原因，现代浏览器会检测并阻止它；您可以解除警告并观察情节出现。更改链接的资源，以便它们也通过 HTTPS 提供服务，或者更好的是省略方案并让浏览器决定。

http://docs.bokeh.org/en/latest/docs/user_guide/embed.html 上提供的 Bokeh 文档说明如下：
When embedding in a page served via HTTPS, any scripts and resources
must also be loaded via HTTPS or the browser will refuse to load due
to an “unsafe” script. For this situation, the Bokeh CDN resources are
also available via HTTPS, by replacing “http” with “https” in the
above URLs.
由于 Heroku 应用程序是通过 HTTPS 提供的，因此 Bokeh 样式表和脚本链接应以 https 开头，而不是 http。

When embedding in a page served via HTTPS, any scripts and resources must also be loaded via HTTPS or the browser will refuse to load due to an “unsafe” script. For this situation, the Bokeh CDN resources are also available via HTTPS, by replacing “http” with “https” in the above URLs.
由于 Heroku 应用程序是通过 HTTPS 提供的，因此 Bokeh 样式表和脚本链接应以 https 开头，而不是 http。
