有人知道我错过了什么吗？

Answer 1

如果您将使用IP地址（http://192.168.11.253）服务器名称（http://..。），则此Web服务运行良好。

Answer 2

如果不了解您的具体错误，我也会抓住稻草。您的destinationUrl似乎是一条不完整的路径。您通常需要指定站点或网站集的整个URL。因此，我希望您的destinationUrl类似http://192.168.11.253/[SiteName]/Shared Documents/28200.xls而不是http://192.168.11.253/Shared Documents/28200.xls"。
