Galaxy Kylin Server v10 sp1 .Net6.0 upload file error access to the path is denied

Before .NET 6, this could be solved by installing libgdiplus on the Linux server. libgdiplus is the main provider of cross-platform implementation of the native side of System.Drawing.Common and is an open source mono project. Address: GitHub - mono/libgdiplus: C-based implementation of the GDI+ API

Therefore, the solution is of course to install the relevant dependencies:

1、CentOS

via one-click commands

sudo curl https://raw.githubusercontent.com/stulzq/awesome-dotnetcore-image/master/install/centos7.sh|sh

or

yum update
yum install libgdiplus-devel -y
ln -s /usr/lib64/libgdiplus.so /usr/lib/gdiplus.dll
ln -s /usr/lib64/libgdiplus.so /usr/lib64/gdiplus.dll

2. Galaxy Kirin V10 or Ubuntu

via one-click commands

sudo curl https://raw.githubusercontent.com/stulzq/awesome-dotnetcore-image/master/install/ubuntu.sh|sh

or

apt-get update
apt-get install libgdiplus -y
ln -s /usr/lib/libgdiplus.so /usr/lib/gdiplus.dll

3、Docker

Add the RUN command to the Dockerfile, take the official asp.net core runtime image, and use asp.net core 2.2 as an example:

FROM microsoft/dotnet:2.2.0-aspnetcore-runtime
WORKDIR /app
COPY . .
RUN apt-get update -y && apt-get install -y libgdiplus && apt-get clean && ln -s /usr/lib/libgdiplus.so /usr/lib/gdiplus.dll
EXPOSE 80
ENTRYPOINT ["dotnet", "<你的入口程序集>"]

It should be noted that this step of apt-get update is essential, otherwise it will report that libgdiplus cannot be found. And because it is an official image and uses a docker image built with Debain10, it will be very slow when compiling and running the build.

Since my project has been upgraded from NetCore3.1 to Net6.0, refer to the link: NetCore3.1 project upgrade to Net6.0_.net 3.0 .net6 upgrade_csdn_aspnet's blog-CSDN blog 

And the System.Drawing.Common used in the project has been replaced by other solutions. If you have no other solution, please refer to: .NET6 System.Drawing.Common universal solution_csdn_aspnet's blog-CSDN blog 

So I modified the code and output the error message in the swagger page call interface test to facilitate solving specific problems. The tips are as follows: 

 Access to the path '/xxx/xxx' is denied. 或 access to the path xxx is denied

It means that the current user rights are not enough, so you need to use chmod to authorize the wwwroot folder: chmod 777 wwwroot

Among them, 777, all users have read and write permissions. Use swagger again to upload as shown below:
