WebService端口号修改

C#中使用webservice接口的时候，返给服务器的IP地址是带上了端口号的。但是有时候不能要那个端口(比如用nginx做了转发)，就需要在服务端处理一下（处理内容就是后面的代码）。此外，需要在配置文件中web.config中的system.web中添加一些东西：

<webServices>

<protocols>

<add name="HttpGet"/>

<add name="HttpPost"/>

<add name="HttpSoap"/>

protocols>

<soapExtensionReflectorTypes>

<add type="CommMethod.OuterPortReflector,CommMethod"/>

soapExtensionReflectorTypes>

webServices>

注：1.type内容是类名，包名。这一点和msdn上的那个人写的有些不同（有可能是版本的问题）（http://blogs.msdn.com/b/kaevans/archive/2005/11/16/493496.aspx）。

         2.如果没有protocols中的内容的话，有可能post和get请求不能被正确识别(未做过验证，只是在博客园上看见过类似问题)。
