I am trying to retrieve the computer name from my computer so I can use it in comparison in my mysql query.

我正在尝试从我的计算机中检索计算机名称，以便在MySQL查询中进行比较。

I would like to define computerName as a variable that grabs the user-defined computer name using NodeJs. This application is being run via electron for windows.

我想将Computer Name定义为一个变量，该变量使用NodeJS获取用户定义的计算机名称。这个应用程序是通过电子视窗运行的。

Any help would be greatly appreciated.

任何帮助都将不胜感激。

You can use the standard nodeJS os API to retrieve the (host)name of a computer, see this API documentation for more details.

您可以使用标准的NodeJS os API来检索计算机的(主机)名称，有关更多详细信息，请参阅此API文档。

const computerName = os.hostname()

On a Mac the only way to reliably get the "ComputerName" as OP requested is to use a child process, which isn't ideal...

在Mac上，可靠地获取OP请求的“ComputerName”的唯一方法是使用子进程，这并不理想……

cp.execSync('scutil --get ComputerName')

cp.execSync（'scutil--get ComputerName'）

Most of the time hostname will === ComputerName, but I found out the hard way today that this is not always the case.

大多数情况下，主机名将=ComputerName，但我今天很痛苦地发现，情况并不总是如此。

const cp = require('child_process')
const os = require('os')

function getComputerName() {
  switch (process.platform) {
    case "win32":
      return process.env.COMPUTERNAME;
    case "darwin":
      return cp.execSync("scutil --get ComputerName").toString().trim();
    case "linux":
      const prettyname = cp.execSync("hostnamectl --pretty").toString().trim();
      return prettyname === "" ? os.hostname() : prettyname;
    default:
      return os.hostname();
  }
}

console.log("getComputerName", getComputerName());
