Asp.Net Core 如何获取IWebHostEnvironment
一、IWebHostEnvironment
服务器主机信息:
网站硬盘目录,网站名称,环境变量名称
// // 摘要: // Provides information about the web hosting environment an application is running // in. public interface IWebHostEnvironment : IHostEnvironment { // // 摘要: // Gets or sets the absolute path to the directory that contains the web-servable // application content files. string WebRootPath { get; set; } // // 摘要: // Gets or sets an Microsoft.Extensions.FileProviders.IFileProvider pointing at // Microsoft.AspNetCore.Hosting.IWebHostEnvironment.WebRootPath. IFileProvider WebRootFileProvider { get; set; } }
// // 摘要: // Provides information about the hosting environment an application is running // in. public interface IHostEnvironment { // // 摘要: // Gets or sets the name of the application. This property is automatically set // by the host to the assembly containing the application entry point. string ApplicationName { get; set; } // // 摘要: // Gets or sets an Microsoft.Extensions.FileProviders.IFileProvider pointing at // Microsoft.Extensions.Hosting.IHostEnvironment.ContentRootPath. IFileProvider ContentRootFileProvider { get; set; } // // 摘要: // Gets or sets the absolute path to the directory that contains the application // content files. string ContentRootPath { get; set; } // // 摘要: // Gets or sets the name of the environment. The host automatically sets this property // to the value of the of the "environment" key as specified in configuration. string EnvironmentName { get; set; } }
二、Startup中获取IWebHostEnvironment
public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } else { app.UseExceptionHandler("/Home/Error"); // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts. app.UseHsts(); } app.UseHttpsRedirection(); app.UseStaticFiles(); xxxx }
三、控制器中获取 IWebHostEnvironment
public class UploadController : Controller { private readonly IWebHostEnvironment _env; public UploadController(IWebHostEnvironment env) { _env = env; } }
