net 5 使用DinkToPdf生成PDF发生以下错误信息。
在本地 window 上运行是没问题的，在linux docker 上部署就出现问题。
在docker上的报错信息：
AggregateException: One or more errors occurred. (Unable to load shared library 'libwkhtmltox' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibwkhtmltox: cannot open shared object file: No such file or directory)
DinkToPdf.SynchronizedConverter.Invoke<TResult>(Func<TResult> delegate)
DllNotFoundException: Unable to load shared library 'libwkhtmltox' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibwkhtmltox: cannot open shared object file: No such file or directory
方法：
1、把https://github.com/rdvojmoc/DinkToPdf/raw/master/v0.12.4/64%20bit/中的libwkhtmltox.dll、libwkhtmltox.so加入到程序运行的根目录。
2、在dockerfile加上：
RUN apt-get update
RUN apt-get install wget libgdiplus -y
