我在本地网络上的服务器上运行Web服务。使用soapUI程序，我可以连接到服务没有问题。所以当我使用soapUI创建一个新项目并输入我的网址'http://xx.xx.xx.xx:9180/SOAOICCT/services/SessionService?wsdl'时，它加载没有问题。Visual Studio 2008添加服务引用错误 - WSDL - 元数据包含无法解析的引用
当我尝试添加服务引用在Visual Studio 2008中使用，我得到一个“添加服务引用错误”相同的URL：
There was an error downloading 'http://xx.xx.xx.xx:9180/SOAOICCT/services/SessionService?wsdl'.
The request failed with HTTP status 504: Gateway Timeout.
Metadata contains a reference that cannot be resolved: 'http://47.166.94.33:9180/SOAOICCT/services/SessionService?wsdl'.
The remote server returned an error: (504) Gateway Timeout.
The remote server returned an error: (504) Gateway Timeout.
If the service is defined in the current solution, try building the solution and adding the service reference again.
当我尝试从Visual Studio使用Wsdl.exe用命令命令提示符我得到一个错误： 
有什么建议吗？
