将文本文件写入映射驱动器会导致错误 - “找不到路径的一部分”

Question

1. 我已使用用户“abc”将网络路径 (\fileserver\myfolder\dev) 映射到“N:”驱动器
2. 使用路径“N:”将文件写入驱动器
3. 我的 IIS 在应用程序直通下运行。

它在本地工作，但是当我将它部署到 DEV 服务器时，它在那里不工作。它抛出错误

“找不到路径的一部分”

不确定需要做什么？

Answer 1

IIS 在不同的帐户下运行，可能看不到映射的驱动器。 试试 UNC 路径 //fileserver/myfolder/dev

如果这不起作用，如果您有一个可以访问映射路径的用户名/密码，您可以尝试模拟
