今天发现highcarts的导出功能报500
找到如下文章：

推荐如下:
This is an error from export.highcharts.com and will be resoled ASAP.
As an alternative to it, it is possible to set up your own exporting server or use local exporting.
Setting up the server: http://www.highcharts.com/docs/export-module/setting-up-the-server
Client side export: http://www.highcharts.com/docs/export-module/client-side-export
Plugin – Client-side export: http://www.highcharts.com/plugin-registry/single/37/highcharts-export-clientside
搭建一个自己的导出服务，然后再使用client side export导出。
