Javascript 如何从传递一些参数的 node.js 执行 .bat 文件？

How to execute a .bat file from node.js passing some parameters?

提问by GibboK

I use node.js v4.4.4 and I need to run a .batfile from node.js.

我使用 node.js v4.4.4，我需要.bat从 node.js运行一个文件。

From the location of the js file for my node app the .bat is runnable using command line with the following path (Window platform):

从我的节点应用程序的 js 文件的位置，.bat 可以使用带有以下路径的命令行运行（Window 平台）：

'../src/util/buildscripts/build.bat --profile ../profiles/app.profile.js'

But when using node I cannot run it, no specific error are thrown.

但是当使用节点时我无法运行它，不会抛出任何特定错误。

What am I doing wrong here?

我在这里做错了什么？

    var ls = spawn('cmd.exe', ['../src/util/buildscripts', 'build.bat', '--profile ../profiles/app.profile.js']);

    ls.stdout.on('data', function (data) {
        console.log('stdout: ' + data);
    });

    ls.stderr.on('data', function (data) {
        console.log('stderr: ' + data);
    });

    ls.on('exit', function (code) {
        console.log('child process exited with code ' + code);
    });

You should be able to run a command like this:

您应该能够运行这样的命令：

var child_process = require('child_process');

child_process.exec('path_to_your_executables', function(error, stdout, stderr) {
    console.log(stdout);
});

The following script solved my issue, basically I had to:

以下脚本解决了我的问题，基本上我必须：

• Converting to absolute path reference to .bat file.

• Passing arguments to .bat using an array.

  var bat = require.resolve('../src/util/buildscripts/build.bat');
  var profile = require.resolve('../profiles/app.profile.js');
  var ls = spawn(bat, ['--profile', profile]);
  
  ls.stdout.on('data', function (data) {
      console.log('stdout: ' + data);
  });
  
  ls.stderr.on('data', function (data) {
      console.log('stderr: ' + data);
  });
  
  ls.on('exit', function (code) {
      console.log('child process exited with code ' + code);
  });
  

• 转换为对 .bat 文件的绝对路径引用。

• 使用数组将参数传递给 .bat。

  var bat = require.resolve('../src/util/buildscripts/build.bat');
  var profile = require.resolve('../profiles/app.profile.js');
  var ls = spawn(bat, ['--profile', profile]);
  
  ls.stdout.on('data', function (data) {
      console.log('stdout: ' + data);
  });
  
  ls.stderr.on('data', function (data) {
      console.log('stderr: ' + data);
  });
  
  ls.on('exit', function (code) {
      console.log('child process exited with code ' + code);
  });
