blocks|key|5296889|text|只是提醒一下。IP地址不能用于唯一标识客户端。NAT防火墙和企业代理无处不在，并且隐藏在单个IP后面的许多用户。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5296890|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Just a caution. IP addresses can't be used to uniquely identify clients. NAT Firewalls and corporate proxies are everywhere, and hide many users behind a single IP.

Try this:

Haven't tried it in a webMethod, but I use it in standard HttpRequests

blocks|key|5296745|text|HttpContext实际上在WebService基类中可用，所以只需使用Context.Request+(或也指向当前上下文的HttpContext.Current+)就可以访问HttpRequest提供的成员。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5296746|entityMap^0|F|A|11|F|1S|J|2I|B|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

The HttpContext is actually available inside the <code>WebService</code> base class, so just use <code>Context.Request</code> (or <code>HttpContext.Current</code> which also points to the current context) to get access to the members provided by the <code>HttpRequest</code>.

blocks|key|773811|text|我做了以下函数：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|773812|static+public+string+sGetIP()

}|code-block|syntax|javascript|773813|这只适用于内部网，如果你有一些代理或http，你应该研究原始IP是否被移动到http数据包中的其他地方。|773814|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

I made the following function:

<pre><code>static public string sGetIP()
{
 try
 {
 string functionReturnValue = null;

 String oRequestHttp =
 WebOperationContext.Current.IncomingRequest.Headers["User-Host-Address"];
 if (string.IsNullOrEmpty(oRequestHttp))
 {
 OperationContext context = OperationContext.Current;
 MessageProperties prop = context.IncomingMessageProperties;
 RemoteEndpointMessageProperty endpoint =
 prop[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
 oRequestHttp = endpoint.Address;
 }
 return functionReturnValue;
 }
 catch (Exception ex)
 {
 return "unknown IP";
 }
}
</code></pre>

This work only in Intranet, if you have some Proxy or natting you should study if the original IP is moved somewhere else in the http packet.

How do I get the caller's IP address in a WebMethod?

<pre><code>[WebMethod]
public void Foo()
{
 // HttpRequest... ? - Not giving me any options through intellisense...
}
</code></pre>

using C# and ASP.NET
