.app.使用红隼中的默认文件不做任何事情

Question

我在一个小项目中有一个 Startup.cs 文件，用于托管 Kestrel 静态文件的 Web服务器：

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<MvcOptions>(options =>
        {
            options.Filters.Add(new RequireHttpsAttribute());
        });
    }
    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        var configBuilder = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("config.json");
        var config = configBuilder.Build();
        var options = new RewriteOptions()
           .AddRedirectToHttps();
        app.UseRewriter(options);
        DefaultFilesOptions defoptions = new DefaultFilesOptions();
        defoptions.DefaultFileNames.Clear();
        defoptions.DefaultFileNames.Add("index.html");
        app.UseDefaultFiles(defoptions);

        app.UseStaticFiles();
        app.UseStaticFiles(new StaticFileOptions()
        {
            FileProvider = new PhysicalFileProvider(Path.Combine(Directory.GetCurrentDirectory(), @"static")),
            RequestPath = new PathString("")
        });
        loggerFactory.AddConsole(config.GetSection(key: "Logging"));
    }
}

但是，它不会尝试加载索引.html或任何东西。如果我手动访问它，它确实有效。

有什么想法吗？

谢谢

理想情况下，您的index.html应该在 Web 根路径 ( wwwroot 下 (，但是，如果您的文件在 ContentRootPathstatic 下(看起来如此(，则需要更改代码以指定DefaultFilesOptions.FileProvider，如下所示：

PhysicalFileProvider fileProvider = new PhysicalFileProvider(
    Path.Combine(Directory.GetCurrentDirectory(), @"static"));
DefaultFilesOptions defoptions = new DefaultFilesOptions();
defoptions.DefaultFileNames.Clear();
defoptions.FileProvider = fileProvider;
defoptions.DefaultFileNames.Add("index.html");
app.UseDefaultFiles(defoptions);
app.UseStaticFiles();
app.UseStaticFiles(new StaticFileOptions()
{
    FileProvider = fileProvider,
    RequestPath = new PathString("")
});

注意：您可能最好使用IHostingEnvironment.ContentRootPath(env.ContentRootPath(而不是Directory.GetCurrentDirectory()第一行(以防万一您想在某个时候更改WebHostBuilder中的内容根目录(。

感谢

CalC的洞察力，这使我更接近 asp.net 核心2.2的答案。以下是我最终需要执行的操作，以便在 Azure 中的主 Web 服务器根目录之外提供默认文档：

public void Configure(IApplicationBuilder app){...
// content is physically stored at /site/abc on an Azure Web App, not /site/wwwroot/abc
string path = Path.Combine(Directory.GetCurrentDirectory(), "abc");
PhysicalFileProvider fileProvider = new PhysicalFileProvider(path); 
DefaultFilesOptions options = new DefaultFilesOptions 
    {
        FileProvider = fileProvider, 
        RequestPath = "/ABC",
    }; 
options.DefaultFileNames.Add("index.html");
app.UseDefaultFiles(options);
app.UseStaticFiles(new StaticFileOptions
                   {
                       FileProvider = fileProvider,
                       RequestPath = "/ABC"
                   });
}

键正在使用匹配的 RequestPath 和 FileProvider 值
