节点。jchild_process捕获密码提示符

How do I use node.js child_process to programatically allow me to supply a password.

如何使用node。js child_process程序允许我提供一个密码。

const spawn = require('child_process').spawn;
const ls = spawn('sudo ls');

ls.stdout.on('data', (data) => {
  console.log(`stdout: ${data}`);
});

ls.stderr.on('data', (data) => {
  console.log(`stderr: ${data}`);
});

ls.on('close', (code) => {
  console.log(`child process exited with code ${code}`);
});

The above throws an error. I am trying to figure out where exactly I can catch where it is wanting the password input and supply that via an environment variable.

上面的操作会抛出一个错误。我正试图弄清楚在哪里可以确切地捕获需要密码输入的位置，并通过环境变量提供密码输入。

I am hoping I can catch when it says Password check to make sure its saying that and then pass the password.

我希望我能抓住它说的密码检查，确保它说了，然后传递密码。

The error is because you're using the spawn command incorrectly.. It should be:

错误在于您不正确地使用了spawn命令。应该是:

const ls = spawn('sudo', ['ls']);

Arguments to the child process are specified as the second argument (in an array).

子进程的参数被指定为第二个参数(在数组中)。

You should then see the prompt for password, and I imagine be able to write to stdin to enter the password (which you're wanting to pass from process.env based on what you've said).

然后您应该会看到密码提示符，我想您可以向stdin写入密码(您希望从进程中传递密码)。基于你说的)。

Edit: Quick search on SO seems to suggest it may not be as straight forward and writing to stdin after the prompt..

编辑:在SO上快速搜索似乎表明它可能不那么直接，并在提示符之后给stdin写信。
