什么是ASP.NET MVC的核心相当于Request.RequestURI？

本文介绍了什么是ASP.NET MVC的核心相当于Request.RequestURI？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我发现的博客文章演示如何垫片熟悉的事物像HttpResponseMessage回ASP.NET MVC的核心，但我想知道什么是应该做同样的事情，如下面的代码新的土办法在控制器的REST Post方法：

I found a blog post that shows how to "shim" familiar things like HttpResponseMessage back into ASP.NET Core MVC, but I want to know what's the new native way to do the same thing as the following code in a REST Post method in a Controller:

// POST audit/values [HttpPost] public System.Net.Http.HttpResponseMessage Post([FromBody]string value) { var NewEntity = _repository.InsertFromString(value); var msg = new System.Net.Http.HttpResponseMessage(System.Net.HttpStatusCode.Created); msg.Headers.Location = new Uri(Request.RequestUri + NewEntity.ID.ToString()); return msg; }

在一个ASP.NET MVC的核心项目，我可以'不像是会得到Request.RequestUri。

In an ASP.NET Core MVC project, I can't seem to get Request.RequestUri.

我试过检查要求，我能够做出这样的函数：

I tried inspecting Request, and I was able to make a function like this:

private string UriStr(HttpRequest Request) { return Request.Scheme + "://" + Request.Host + Request.Path; // Request.Path has leading / }

所以，我可以写 UriStr（请求）来代替。但我不知道这是正确的。我觉得像我黑客攻击我的方式左右，而无法正常使用此。

So I could write UriStr(Request) instead. But I'm not sure that's right. I feel like I'm hacking my way around, and not using this correctly.

一个的有关问题早期非核心ASP.NET MVC的版本要求如何得到网站的基本URL。

A related question for earlier non-Core ASP.NET MVC versions asks how to get the base url of the site.

推荐答案

一个更清洁的方法是使用 UriBuilder ：

A cleaner way would be to use a UriBuilder:

private static Uri GetUri(HttpRequest request) { var builder = new UriBuilder(); builder.Scheme = request.Scheme; builder.Host = request.Host.Value; builder.Path = request.Path; builder.Query = request.QueryString.ToUriComponent(); return builder.Uri; }

（未测试，代码可能需要一些调整）
