前言 本文主要介绍的是关于.NET Core单文件发布静态编译AOT CoreRT,将.NET Core应用打包成一个可执行文件并包含运行时。 支持Windows, MacOS and Linux x64 w/ RyuJIT codegen。 示例项目: https://github.com/dotnet/corert/tree/master/samples/WebApi 下面来实际体验。 首先确保安装C++编译环境,以及.NET Core 2.0 以上版本SDK。 新建WebAPI应用 打开命令提示符,输入如下: dotnet new webapi -o zeroapi cd zeroapi 新建WebAPI应用。 添加CoreRT到项目 目前CoreRT还是alpha版,在myget上有包。 首先添加一个nuget.config dotnet new nuget 然后在 <add key="dotnet-core" value="https://dotnet.myget.org/F/dotnet-core/api/v3/index.json" /> <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" /> 接着添加Microsoft.DotNet.ILCompiler包引用: dotnet add package Microsoft.DotNet.ILCompiler -v 1.0.0-alpha-* 替换默认services并处理反射 打开Startup.cs ,将 接着创建一个rd.xml 配置文件,用于反射处理运行时,确保反射程序集编译到程序中。 rd.xml配置文件如下:

Include="Microsoft.AspNetCore" Version="2.0.1" /> <PackageReference Include="Microsoft.AspNetCore.Mvc.Core" Version="2.0.1" /> <PackageReference Include="Microsoft.AspNetCore.Mvc.Formatters.Json" Version="2.0.1" /> 接着将 ValuesController 更改一下,确保功能正常,如下: public class ValuesController { [HttpGet("/")] public string Hello() => "Hello World! LineZero AOT"; // GET api/values [HttpGet("/api/values")] public IEnumerable<string> Get() { return new string[] { "AOT", "CoreRT" }; } // GET api/values/5 [HttpGet("/api/values/{id}")] public string Get(int id) { return "Your value is " + id; } } 程序改造完成,接着最重要的发布。 还原并发布 发布之前,使用dotnet run 确保功能正常运行。 发布请打开 x64 Native Tools Command Prompt for VS 2017 ,注意一定在此命令行发布。在开始菜单找到 Visual Studio 2017,打开就能找到。 发布命令还是 这里发布Windows 64位 发布完成后,打开bin\x64\release\netcoreapp2.0\win-x64\publish 文件夹,里面zeroapi.exe即为最终文件,执行即可。 可以看到最终大小为21m左右。然后访问http://localhost:5000/ 如图: 控制台Demo 新建一个控制台应用,使用AOT发布。 单纯控制台,没有反射的内容,无需要rd.xml 文件。 代码如下: class Program { static void Main(string[] args) { Console.WriteLine("Hello World!"); Console.WriteLine("LineZero AOT Demo!"); Console.ReadKey(); } } 最终 最终单个文件大小不到4m! 目前该技术还是早期版本,期待微软最终带到正式版。 GitHub:https://github.com/dotnet/corert 总结 以上就是这篇文章的全部内容了,希望本文的内容对大家的学习或者工作具有一定的参考学习价值,如果有疑问大家可以留言交流,谢谢大家对极客世界的支持。 |
