在节点中设置已安装网络驱动器的路径

Question

我正在尝试使用 windows-network-drive 模块和 fs 模块写入 Node 中的映射网络驱动器。

networkDrive.mount('\\server', 'Z', 'username', 'password')
  .then(driveLetter => {

  let filePath;

  filePath = path.join(driveLetter + ":\path\to\directory", "message.txt");

  fs.writeFile(filePath, "text", (err) => {
    if (err) throw err;
    console.log('The file has been saved!');
  });
})
.catch(err => {
  console.log(err)
});

如何获取写入远程位置的连接和路径？

需要传入盘符吗？如果有，我该如何找到它？

(node:4796) UnhandledPromiseRejectionWarning:
ChildProcessError: Command failed: net use Z: "\server" /P:Yes /user:username password System error 67 has occurred.

The network name cannot be found.

net use Z: "\server" /P:Yes /user:username password (exited with error code 2)

P.S。此代码记录 Z

networkDrive.mount('\\server\path\to\directory', 'Z', 'mdadmin', 'Password1!')
  .then(function (driveLetter) {
    console.log(driveLetter);
    fs.writeFile('L_test.txt', 'list', (err) => {
      if (err) throw err
    })
});

Answer 1

我不确定您遇到了什么错误，所以这里有一些您在使用 windows-network-drive.

时的提示

转义特殊字符

Windows 使用 \ 分隔目录。 \ is a special character 在 JavaScript 字符串中，必须像这样转义 \\.例如C:\file.txt 在字符串中将是 C:\\file.txt.

尽可能使用 POSIX 分隔符

由于使用转义 \ 读取路径会增加难度，我建议改用 /。 windows-network-drive 应该可以很好地处理这两个问题。例如C:\file.txt 在字符串中将是 C:/file.txt.

例子

我试图使它与您的示例相匹配，但做了一些更改，以便它可以在任何 windows 机器上运行。

let networkDrive = require("windows-network-drive");

/**
 * https://github.com/larrybahr/windows-network-drive
 * Mount the local C: as Z:
 */
networkDrive.mount("\\localhost\c$", "Z", undefined, undefined)
    .then(function (driveLetter)
    {
        const fs = require("fs");
        const path = require("path");
        let filePath;

        /**
         * This will create a file at "Z:\message.txt" with the contents of "text"
         * NOTE: Make sure to escape '\' (e.g. "\" will translate to "\")
         */
        filePath = path.join(driveLetter + ":\", "message.txt");
        fs.writeFile(filePath, "text", (err) =>
        {
            if (err) throw err;
            console.log('The file has been saved!');
        });
    });

Answer 2

要从 IIS 中托管的 REST 服务写入，您需要在服务器上正确设置权限。

You will need to set the identity of the Application Pool of your site.

You will need to grant write permissions to match that account or account group to the folder that you are trying to write to.

注意：如果您通过 OS 将文件夹映射到网络驱动器号，则它仅在用户帐户级别定义。

So, if you have mapped the folder location to a drive letter (in this case 'X:'), instead of writing to

fs.writeFile('X:/test.txt', 'text', (err) => {
  if (err) throw err
})

您必须写入完整路径

fs.writeFile('\\servername\path\to\director\test.txt', 'text', (err) => {
  if (err) throw err
})

注意：反斜杠需要转义，所以 Windows 文件系统会显示类似 \servername\path\to\directory.
