本地测试通过 docker部署服务器后报错 The type initializer for Spire.Xls.Core.Spreadsheet.XlsPageSetupBase threw an exception. 由于缺少依赖 libc6-devlibgdipluslibx11-dev。由于目标服务器为内网环境无外网环境。官网给出答案在dockerfile中 增加
RUN apt-get update \ apt-get install -y --allow-unauthenticated \ libc6-dev \ libgdiplus \ libx11-dev \ rm -rf /var/lib/apt/lists/*
尝试解决 创建docker镜像。由于项目已 mcr.microsoft.com/dotnet/aspnet:6.0-bullseye-slim 为基础镜像以此新建一个环境镜像。
# 进入容器部署环境
docker run -it mcr.microsoft.com/dotnet/aspnet:6.0-bullseye-slim /bin/bash
apt-get update \ apt-get install -y --allow-unauthenticated \ libc6-dev \ libgdiplus \ libx11-dev \ rm -rf /var/lib/apt/lists/*#部署成功后 退出容器并将容器打包为新镜像。
docker commit -adjc -madd libc6-dev,libgdiplus,libx11-dev based on .netcore5.0 28a66ebccd55 dotnetcore-djc:5.2
# -a :作者 -m: 备注信息 28a66xxx : 容器id可通过docker ps -a 查看 #新的镜像名称为dotnetcore-djc:5.2vs项目dockerfile中修改基础镜像FROM dotnetcore-djc:5.2 AS base
发布后又报错System.TypeInitializationException: The type initializer for ‘Gdip’ threw an exception. google后发现 libgdiplus 包使用了 System.Drawing.Common .net6后仅在window上支持我目前使用.net5, 也是平台兼容性报错不知为何。 尝试解决 在项目中添加如下代码
AppContext.SetSwitch(System.Drawing.EnableUnixSupport, true);
发布后又报错Index was out of range. Must be non-negative and less than the size of the collection. (Parameter index) 尝试解决 升级 FreeSpire.XLS 包 由原来的 10.10.0 升级为 12.7.0
导出图片后发现中文字体乱码。 尝试解决
#将window中 C:\Windows\fonts 内需要得字体拷贝至容器内 /usr/share/fonts/windows文件夹内。
#更改字体库的权限
chmod 755 /usr/share/fonts/windows/*#进入文件夹内
mkfontscale //字体扩展
mkfontdir //新增字体目录
fc-cache-fv //刷新缓存#肯定会报错mkfontscale: command not found 等
# 由于Docker mcr.microsoft.com/dotnet/aspnet:5.0 基础镜像中不包含该包需手动安装。
apt-get update apt-get upgrade
apt-get install ttf-mscorefonts-installer // 安装mkfontscale mkfontdir 命令#报错 package ttf-mscorefonts-intaller has no installation candidate 错误。
#由于系统初始的资源库找不到指定的包需要更新 对应 的镜像地址。
#我的/etc/apt/sources.list 中 初始镜像地址为 Debian buster 所以添加如下镜像至sources.list中。
#如果添加版本错误的话update 会报错。

修改 .sln 同目录下的Dockerfile文件内容如下
#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.#这种模式是直接在构建镜像的内部编译发布dotnet项目。
#注意下容器内输出端口是9291
#如果你想先手动dotnet build成可执行的二进制文件然后再构建镜像请看.Api层下的dockerfile。FROM mcr.microsoft.com/dotnet/aspnet:6.0-bullseye-slim AS base
