node.js中的execFile不执行Windows命令

Question

我的意图是运行Windows .EXE。为了测试，首先我尝试一些简单的Windows命令。但似乎execFile只执行Linux命令。例如，如果我说要执行“DIR”，它将执行。但是如果我执行“CD”，它不会。然后，如果我执行“pwd”的工作。

我已经阅读了有关execFile的文档，但没有解决这个问题。这里是我的代码片段：

var user_input = req.body.name; 
var command_array = user_input.split(/\s+/); 
var command = command_array.shift(); 
var params = command_array; 
console.log("Client Command: " + command); 
console.log("Client Arguments: " + params); 

var execFile = require('child_process').execFile 

// this launches the executable and returns immediately 
var child = execFile(command, params, 
    function (error, stdout, stderr) { 
     . . . 
     }); 

有人可以帮助我吗？

这里是输出：

Answer 1

这是因为execFile旨在执行文件，像你这样的EXE，这是不打开外壳。如果你想执行一个像cd这样的命令，你应该使用exec函数。 pwd作品为你和cd没有可能是因为有一个pwd文件，您的PATH的一个文件夹（什么能让你在cmd写pwd，窗户本身并不支持pwd命令）
