我怎么知道我的服务器名称和站点名称?
您是开发人员，您***了解您要定位的服务器和站点.我建议您在造成更多损害之前接受一些有关SharePoint开发的培训.

How can I know my server name and site name?????

You are the developer, you had better know the server and site you are targeting. I would suggest you get some training on SharePoint development before you cause more damage.
