asp.net core项目在centos7.x下GUI 绘图组件System.Drawing.Common异常问题
最近做了个asp.netcore 3.1SDK 的测试项目在CentOS环境下部署 发现绘制的验证码没法正常显示(windows下是正常的),查看日志发现
1 System.TypeInitializationException: The type initializer for 'System.DrawingCore.GDIPlus'
threw an exception. ---> System.DllNotFoundException: Unable to load shared library 'gdiplus'
or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment
variable: libgdiplus: cannot open shared object file: No such file or directory
由此应该是少一些GUI图形绘制组件 参考了一些文章后
得出解决办法:
1.在centos下安装libgdiplus-devel;
命令:
yum install libgdiplus-devel
2.重启 .netcore 服务(systemctl restart xxxxxx.service) 我是直接安装的centos下SDK 没用docker
我相信用docker容器部署的也会出现这个问题 如果docker容器中遇到上述问题 可以试试进入容器 安装上面组件 重启容器
