如何在Aspnet5中获取Request.ApplciationPath

Question

考虑网址：http://website.com/application
在早期版本的.Net中，

HttpContext.Current.Request.Url.Host = "website.com"
HttpContext.Current.Request.ApplicationPath = "/application"

在Aspnet5 RC1中，获取主机很好，但是如何获得Request.ApplicationPath？

Answer 1

使用IApplicationEnvironment：

private readonly IApplicationEnvironment _appEnvironment;
public HomeController(IApplicationEnvironment appEnvironment)
{
    _appEnvironment = appEnvironment;
}
public IActionResult Index()
{
    var path = _appEnvironment.ApplicationBasePath;
    // other codes
}
