本文章主要说明asp.net core中静态资源处理方案:
首先明确contentRoot和webroot这两个概念
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory()) //设置contentroot
.UseWebRoot("mywwwroot") //设置webroot
.UseUrls("http://*:5000") //其他电脑可以用ip地址访问
.Build();
StartUp中的代码
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseStaticFiles();//开启静态文件访问
//自定义静态文件访问
app.UseStaticFiles(new StaticFileOptions(){
FileProvider = new PhysicalFileProvider(Path.Combine(Directory.GetCurrentDirectory(), "mystatic")),
RequestPath = new PathString("/sam/static")
});
//配置mvc
app.UseMvc(routers=>{
routers.MapRoute("default", "{controller=Home}/{action=Index}/{id?}");
});
}
效果图下图:
实现代码如下:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseDirectoryBrowser(new DirectoryBrowserOptions(){
FileProvider = new PhysicalFileProvider(Path.Combine(env.ContentRootPath, "Controllers")),
RequestPath = new PathString("/controller")
});
}
app.UseDefaultFiles方法开启默认访问的配置,配置项用DefaultFilesOption类表示,代码如下:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
//默认文件
DefaultFilesOptions defaultFiles = new DefaultFilesOptions();
defaultFiles.DefaultFileNames.Clear();
defaultFiles.DefaultFileNames.Add("myindex.html");
app.UseDefaultFiles(defaultFiles);
app.UseStaticFiles(); //开启静态文件访问
}
注意此配置一定要在所有Use之前,否则设置不生效
UserFileServer包含了UseStaticFiles, UseDefaultFiles, UserDirectoryBrowser的功能
app.UseFileServer(new FileServerOptions(){
EnableDefaultFiles, //是否开启默认文档
EnableDirectoryBrowsing, //是否开启目录浏览
DefaultFilesOptions, //默认文件设置
StaticFileOptions, //静态资源访问设置
DirectoryBrowserOptions, //目录浏览设置
});
静态模块是不对文件进行权限检查的,包含wwwroot下的文件和文件夹。如果相进行权限控制,可以使用action返回一个FileResult来实现:
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");;
}
此类包含一个将文件扩展名映射到MIME内容类型的集合,代码如下:
FileExtensionContentTypeProvider provider=new FileExtensionContentTypeProvider();
provider.Mappings.Add(".sam", "text/plain");
//自定义静态文件访问
app.UseStaticFiles(new StaticFileOptions(){
FileProvider = new PhysicalFileProvider(Path.Combine(Directory.GetCurrentDirectory(), "mystatic")),
RequestPath = new PathString("/sam/static"),
ContentTypeProvider = provider
});
