一、Web根目录访问

1. 创建wwwroot文件夹
2. app.UseStaticFiles(); // 启⽤静态⽂件中间件
3. url/路径 进行访问

二、Web根目录之外的文件

app.UseStaticFiles(new StaticFileOptions
{
     FileProvider = new PhysicalFileProvider(
     	Path.Combine(builder.Environment.ContentRootPath,
    	"MyStaticFiles")),
     RequestPath = "/StaticFiles"
});

MyStaticFiles是我们在项⽬中⾃定义的⽂件夹。
RequestPath参数⽤于指定静态资源的请求 路径，这⾥我们设置为StaticFiles，当我们再次去访问时，就可以通过http://localhost:527 7/StaticFiles/…查看文件了

三、目录浏览

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddDirectoryBrowser();
// Add services to the container.

var app = builder.Build();
app.UseStaticFiles(new StaticFileOptions
{
    FileProvider = new PhysicalFileProvider(
        Path.Combine(builder.Environment.ContentRootPath,
        "MyStaticFiles")),
    RequestPath = "/StaticFiles"
});

app.UseDirectoryBrowser(new DirectoryBrowserOptions
{
    FileProvider = new PhysicalFileProvider(
               Path.Combine(builder.Environment.ContentRootPath,
                      "MyStaticFiles")),
    RequestPath= "/StaticFiles"
});
