To get started with static files of asp.net core, asp. netcore

This article mainly describes the static resource processing solution in asp.net core:

I. static file service

First, clarify the concepts of contentRoot and webroot.

• ContentRoot: The project folder of the web, which contains other folders such as webroot and other bin.
• Webroot: webroot is a site folder that can be accessed by URLs. Default Value: "contentroot/wwwroot"
• The implementation code is as follows:
  Code in Program

Public static IWebHost BuildWebHost (string [] args) => WebHost. createdefabuilder Builder (args ). useStartup <Startup> (). useKestrel (). useContentRoot (Directory. getCurrentDirectory () // set contentroot. useWebRoot ("mywwwroot") // sets webroot. useUrls ("http: // *: 5000") // other computers can use IP addresses for access. build ();

Code in StartUp

Public void Configure (IApplicationBuilder app, IHostingEnvironment env) {app. useStaticFiles (); // enable static file access // custom static file access app. useStaticFiles (new StaticFileOptions () {FileProvider = new PhysicalFileProvider (Path. combine (Directory. getCurrentDirectory (), "mystatic"), RequestPath = new PathString ("/sam/static")}); // configure the mvc app. useMvc (routers => {routers. mapRoute ("default", "{controller = Home}/{action = Index }/ {Id ?} ");});}

:

1.1 directory browsing

The implementation code is as follows:

public void Configure(IApplicationBuilder app, IHostingEnvironment env){      app.UseDirectoryBrowser(new DirectoryBrowserOptions(){        FileProvider = new PhysicalFileProvider(Path.Combine(env.ContentRootPath, "Controllers")),        RequestPath = new PathString("/controller")    }); }

1.2 default document

The app. UseDefaultFiles method enables the default access configuration. The configuration item is represented by the DefaultFilesOption class. The Code is as follows:

Public void Configure (IApplicationBuilder app, IHostingEnvironment env) {// default file ultultfilesoptions defaultFiles = new DefaultFilesOptions (); defaultFiles. defaultFileNames. clear (); defaultFiles. defaultFileNames. add ("myindex.html"); app. useDefaultFiles (defaultFiles); app. useStaticFiles (); // enable static file access}

Note that this configuration must be before all Use operations; otherwise, the configuration will not take effect.

1.3 UseFileServer

UserFileServer includes UseStaticFiles, UseDefaultFiles, and UserDirectoryBrowser functions.

App. useFileServer (new FileServerOptions () {EnableDefaultFiles, // whether to enable the default file EnableDirectoryBrowsing, // whether to enable directory browsing DefaultFilesOptions, // set StaticFileOptions in the default file, // set DirectoryBrowserOptions for static resource access, // directory browsing settings });

Ii. static file authorization

The static module does not perform permission checks on files, including files and folders under wwwroot. For permission control, you can use action to return a FileResult:

private string basePath = Common.Uitls.HostingEnvironment.ContentRootPath;public FileResult Index(int id){    if(id == 1){        return new PhysicalFileResult(Path.Combine(basePath, "aufolder","author.html"), "text/html");    }    return new PhysicalFileResult(Path.Combine(basePath, "error.html"), "text/html");;}

Iii. Use of the FileExtensionContentTypeProvider class

This class contains a set that maps file extensions to MIME content types. The Code is as follows:

FileExtensionContentTypeProvider provider = new FileExtensionContentTypeProvider (); provider. mappings. add (". sam "," text/plain "); // custom static file access app. useStaticFiles (new StaticFileOptions () {FileProvider = new PhysicalFileProvider (Path. combine (Directory. getCurrentDirectory (), "mystatic"), RequestPath = new PathString ("/sam/static"), ContentTypeProvider = provider });

• The FileExtensionContentTypeProvider class is associated with UseStaticFiles
• The extension starts.
• The running result is as follows:
