The problem was in configuration, this is not documented well. Adding this:

<pre><code># spray-can config
spray.can {
 server {
 remote-address-header = on
 }
}
</code></pre>

forces spray to add remote IP header to the main headers. Address header will have name Remote-Address.

blocks|key|14124|text|如果您使用的是喷雾路由，那么有一个用于提取客户端ip的指令，称为clientIP+=)，要使用它，只需编写：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|14125|(path("somepath")+&+get)+{

If you are using spray routing, then there is a directive for extracting client ip called <code>clientIP</code> =)
To use it just write:

<pre><code>(path("somepath") &amp; get) {
 clientIP { ip =&gt;
 complete(s"ip is $ip")
 }
}
</code></pre>

more then simple, but you need still need to add explicit configuration to get IP from request. And a little comment, maybe i didn't get something but in spray there is no <code>implicit request</code>. Actually incoming request percolates through your routing structure, if you take a look into the routing library you'll see that route is just an alias: <code>type Route = RequestContext =&gt; Unit</code>. So if you need to get access to the context at some point just write:

<pre><code>(path("somepath") &amp; get) {
 clientIP { ip =&gt; 
 reqCont =&gt; reqCont.complete(s"ip is $ip")
 }
}
</code></pre>

But remember about static route part and dynamic part.

You need both what Alex K and 4lex1v have posted. 

The below config forces spray to add remote IP header to the main headers. Address header will have name Remote-Address.

<pre><code># spray-can config
spray.can {
 server {
 remote-address-header = on
 }
}
</code></pre>

You will then need to add the <code>clientIP</code> directive around the route. 

<pre><code>(path("somepath") &amp; get) {
 clientIP { ip =&gt;
 complete(s"ip is $ip")
 }
}
</code></pre>

This will return an object of type <code>RemoteAddress</code>, from which you can extract the IP.

<pre><code>remoteAddress.toOption.map(_.getHostAddress).getOrElse("Unknown")
</code></pre>

The <code>clientIP</code> directive will extract the IP if it exists, however the header that it extracts the value from will not be recorded unless you set the <code>remote-address-header</code> flag to <code>on</code>. It defaults to <code>off</code>.

More info can now be found in the Spray documentation. <a href="http://spray.io/documentation/1.2.4/spray-routing/misc-directives/clientIP/#example" rel="nofollow noreferrer">http://spray.io/documentation/1.2.4/spray-routing/misc-directives/clientIP/#example</a>

I am looking at headers that are coming in, but no IP seems to be there:

<pre><code>HttpRequest(GET,http://127.0.0.1:8080/track/check,List(Accept-Language: uk-UA, 
uk, ru, en-US, en, Encoding: gzip, deflate, sdch, User-Agent: Mozilla/5.0 
(Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29
Safari/537.36, Accept: text/html, application/xhtml+xml, application/xml;q=0.9, 
*/*;q=0.8, Connection: keep-alive, Host: 127.0.0.1:8080),EmptyEntity,HTTP/1.1)
</code></pre>

This is a request I did from browser. Basically I am looking in:

<pre><code>path("check") {
 get {
 implicit request =&gt; {
 val a = 5
 }
 }
 } ~
</code></pre>

Here request object doesn't have any information about the IP address. Any help is very appreciated. thanks.
