ASP.NET Core 设置默认起始页（如default.html）
测试页面foo.html
在Startup.cs内使用middleware
代码如下：
1 DefaultFilesOptions defaultFilesOptions = new DefaultFilesOptions();
2 defaultFilesOptions.DefaultFileNames.Clear();
3 defaultFilesOptions.DefaultFileNames.Add("foo.html");
4 app.UseDefaultFiles(defaultFilesOptions);
5 app.UseStaticFiles(); 1 DefaultFilesOptions defaultFilesOptions = new DefaultFilesOptions(); 2 defaultFilesOptions.DefaultFileNames.Clear(); 3 defaultFilesOptions.DefaultFileNames.Add("foo.html"); 4 app.UseDefaultFiles(defaultFilesOptions); 5 app.UseStaticFiles();
或者:
1 FileServerOptions fileServerOptions = new FileServerOptions();
2 fileServerOptions.DefaultFilesOptions.DefaultFileNames.Clear();
3 fileServerOptions.DefaultFilesOptions.DefaultFileNames.Add("foo.html");
4 app.UseFileServer(fileServerOptions); 1 FileServerOptions fileServerOptions = new FileServerOptions(); 2 fileServerOptions.DefaultFilesOptions.DefaultFileNames.Clear(); 3 fileServerOptions.DefaultFilesOptions.DefaultFileNames.Add("foo.html"); 4 app.UseFileServer(fileServerOptions);
运行结果：
Static Files in ASP.NET Core By default an ASP.NET Core application will not serve static files; // 默认情况下ASP.NET Core应用程序时不支持静态文件的。 The default directory for static files is wwwroot; //为静态文件提供存储的默认路径时wwwroot； To serve static files UseStaticFiles() middleware is required; //UseStaticFiles() 。在使用静态文件时必须 To serve a default file UseDefaultFiles() middleware is required; //UserDefaultFiles() 。 在使用默认文件时必须 The following are the default files: //列举了4种默认文件名 index.htm index.html default.htm default.html UseDefaultFiles() must be registered before UseStaticFiles(); //UseDefaultFiles()必须先于UseStatciFiles()注册。 UseFileServer combines the functionality of UseStaticFiles,UseDefaultFiles and UseDirectoryBrowser middleware. //UseFileServer 集合了UseStaticFiles,UseDefaultFiles and UseDirectoryBrowser这些中间件的所有功能。
