blocks|key|566331|text|不幸的是，Uri的PCL版本不支持流行的GetLeftPart解决方案。然而，GetComponents是这样的，所以如果您需要可移植性，这应该可以做到这一点：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|566332|uri.GetComponents(
++++UriComponents.SchemeAndServer+%7C+UriComponents.UserInfo,+UriFormat.Unescaped);|code-block|syntax|javascript|566333|entityMap^0|5|3|K|B|13|D|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|U|8|@]|D|@]|E|$]]]|L|$]]

The popular <code>GetLeftPart</code> solution is not supported in the PCL version of <code>Uri</code>, unfortunately. <code>GetComponents</code> is, however, so if you need portability, this should do the trick:

<pre><code>uri.GetComponents(
 UriComponents.SchemeAndServer | UriComponents.UserInfo, UriFormat.Unescaped);
</code></pre>

blocks|key|566204|text|我相信上面的答案没有考虑到当网站不在网站的根部时。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|566205|这是用于WebApi控制器的：|566206|string+baseUrl+=+(Url.Request.RequestUri.GetComponents(

I believe that the answers above doesn't consider when the site is not in the root of the website. 

This is a for WebApi controller: 

<pre><code>string baseUrl = (Url.Request.RequestUri.GetComponents(
 UriComponents.SchemeAndServer, UriFormat.Unescaped).TrimEnd('/') 
 + HttpContext.Current.Request.ApplicationPath).TrimEnd('/') ;
</code></pre>

blocks|key|566112|text|对我来说，到目前为止，@warlock's看起来是最好的答案，但我过去一直在用它；|type|unstyled|depth|inlineStyleRanges|entityRanges|data|566113|string+baseUrl+=+Request.Url.GetComponents(
++++UriComponents.SchemeAndServer,+UriFormat.UriEscaped)+++|code-block|syntax|javascript|566114|或者在WebAPI控制器中；|566115|string+baseUrl+=+Url.Request.RequestUri.GetComponents(
++++UriComponents.SchemeAndServer,+UriFormat.Unescaped)|566116|这很方便，这样你就可以选择你想要的转义格式。我不清楚为什么有两个如此不同的实现，据我所知，这个方法和@warlock在这种情况下返回了完全相同的结果，但是看起来GetLeftPart()也可以用于非服务器Uri，比如mailto标记。|offset|length|style|CODE|566117|entityMap^0|0|0|0|0|28|D|30|6|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|W|8|@$M|X|N|Y|O|P]|$M|Z|N|10|O|P]]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|R|$]]

To me, @warlock's looks like the best answer here so far, but I've always used this in the past;

<pre><code>string baseUrl = Request.Url.GetComponents(
 UriComponents.SchemeAndServer, UriFormat.UriEscaped) 
</code></pre>

Or in a WebAPI controller;

<pre><code>string baseUrl = Url.Request.RequestUri.GetComponents(
 UriComponents.SchemeAndServer, UriFormat.Unescaped)
</code></pre>

which is handy so you can choose what escaping format you want. I'm not clear why there are two such different implementations, and as far as I can tell, this method and @warlock's return the exact same result in this case, but it looks like <code>GetLeftPart()</code> would also work for non server Uri's like <code>mailto</code> tags for instance.

blocks|key|566221|text|这是一种更愚蠢的方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|566222|VirtualPathUtility.ToAbsolute("~/");|code-block|syntax|javascript|566223|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

This is a much more fool proof method.

<pre><code>VirtualPathUtility.ToAbsolute("~/");

blocks|key|782462|text|根据Warlock所写的，我发现如果你不在你的网站的根目录下，就需要虚拟路径根目录。(这适用于MVC+Web+API控制器)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|782463|String+baseUrl+=+Request.RequestUri.GetLeftPart(UriPartial.Authority)+

Based on what Warlock wrote, I found that the virtual path root is needed if you aren't hosted at the root of your web. (This works for MVC Web API controllers)

<pre><code>String baseUrl = Request.RequestUri.GetLeftPart(UriPartial.Authority) 
+ Configuration.VirtualPathRoot;

you could possibly add in the port for non port 80/SSL?

something like:

<pre><code>if (HttpContext.Current.Request.ServerVariables["SERVER_PORT"] != null &amp;&amp; HttpContext.Current.Request.ServerVariables["SERVER_PORT"].ToString() != "80" &amp;&amp; HttpContext.Current.Request.ServerVariables["SERVER_PORT"].ToString() != "443")
 {
 port = String.Concat(":", HttpContext.Current.Request.ServerVariables["SERVER_PORT"].ToString());
 }
</code></pre>

and use that in the final result?

I want to write a little helper method which returns the base URL of the site. This is what I came up with:

<pre><code>public static string GetSiteUrl()
{
 string url = string.Empty;
 HttpRequest request = HttpContext.Current.Request;

 if (request.IsSecureConnection)
 url = "https://";
 else
 url = "http://";

 url += request["HTTP_HOST"] + "/";

 return url;
}
</code></pre>

Is there any mistake in this, that you can think of? Can anyone improve upon this?

How can I get the baseurl of site?

服务器

我想写一个小帮手方法，返回网站的基本URL。这是我想出来的：public static string GetSiteUrl(){    string url = string.Empty;    HttpRequest request = HttpContext.Current.Request;    if (request.IsSecureConnection)        url = "ht
