node.js中的execFile不執行Windows命令

Question

我的意圖是運行Windows .EXE。爲了測試，首先我嘗試一些簡單的Windows命令。但似乎execFile只執行Linux命令。例如，如果我說要執行「DIR」，它將執行。但是如果我執行「CD」，它不會。然後，如果我執行「pwd」的工作。

我已經閱讀了有關execFile的文檔，但沒有解決這個問題。這裏是我的代碼片段：

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) { 
     . . . 
     }); 

有人可以幫助我嗎？

這裏是輸出：

Answer 1

這是因爲execFile旨在執行文件，像你這樣的EXE，這是不打開外殼。如果你想執行一個像cd這樣的命令，你應該使用exec函數。 pwd作品爲你和cd沒有可能是因爲有一個pwd文件，您的PATH的一個文件夾（什麼能讓你在cmd寫pwd，窗戶本身並不支持pwd命令）
