NET Core & VS Code 之路(2) Web API
开发Core项目的条件
看到VS包的体积,以及不想往下走了.
幸亏,ms出了VS Code,可开发.NET Core项目.实际上记事本也能写Core代码,但是开发是需要调试的.
所以本系列将持续用VS Code开发.以代码为主,关键点会加以注释
由于公司事比较多,一直没来得及更新
目录
Web API
- dotnet new 添加Core项目
- project.json添加依赖
-
"Microsoft.AspNetCore.Server.Kestrel"
-
"Microsoft.AspNetCore.Mvc"
-
- 添加Startup.cs
- 添加ValuesController.cs
- 修改Program.cs

using Microsoft.AspNetCore.Builder;using Microsoft.Extensions.DependencyInjection;public class Startup{ public void Configure(IApplicationBuilder app) { app.UseMvc();//使用MVC管道 } public void ConfigureServices(IServiceCollection services) { services.AddMvc();//MVC加入到DI容器中 }} |

MVC
在.NET Core中,MVC和Web API实际上走的同一个管道
本例子会在上面的Web API基础上修改
- 添加和修改project.json
- Microsoft.AspNetCore.Razor.Tools
- 添加HomeController
- 添加Index.cshtml
- 修改Program.cs
MVC中因为有razor动态编译,所以不仅仅添加1个依赖即可
project.json修改的内容

静态文件
- 添加依赖:project.json
- Microsoft.AspNetCore.StaticFiles
- 注册管道:Startup.cs
- 添加静态文件:wwwroot
project.json

public void Configure(IApplicationBuilder app){ app.UseStaticFiles();//需要在mvc前 否则将优先被mvc路由匹配执行 app.UseMvc();} |
添加静态文件
静态文件默认是以wwwroot文件夹为根目录
注意:
- 添加依赖后,需要Restore后才能使用该库
- 本节由于篇幅问题,去除了配置文件的大量说明
