我在本地網絡上的服務器上運行Web服務。使用soapUI程序，我可以連接到服務沒有問題。所以當我使用soapUI創建一個新項目並輸入我的網址'http://xx.xx.xx.xx:9180/SOAOICCT/services/SessionService?wsdl'時，它加載沒有問題。Visual Studio 2008添加服務引用錯誤 - WSDL - 元數據包含無法解析的引用
當我嘗試添加服務引用在Visual Studio 2008中使用，我得到一個「添加服務引用錯誤」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.
當我嘗試從Visual Studio使用Wsdl.exe用命令命令提示符我得到一個錯誤： 
有什麼建議嗎？
