Laravel控制器无法运行Node.js翻译脚本的问题排查

我尝试从Laravel 7.29的控制器函数中调用项目根目录下的Node.js脚本translate.js实现翻译功能（英文转印地语）。直接在命令行执行node translate.js "I want to try convert my text into hindi language." hi能正常得到结果，但通过控制器执行时总是报错。

报错信息 #

The command ""node D:\Laragon\www\krutech\translate.js ""I want to try convert my text into hindi language."" hi"" failed. Exit Code:1(General error) Working directory: D:\Laragon\www\krutech\public Output: ================ Error Output: ================ The filename, directory name, or volume label syntax is incorrect.

translate.js 代码 #

const { translate } = require('@vitalets/google-translate-api');

function translateText(text, targetLang) {
    return translate(text, { to: targetLang })
        .then(res => {
            return res.text;
        })
        .catch(err => {
            console.error(err);
            return "Translation failed";
        });
}

module.exports = {
    translateText: translateText
};

const textToTranslate = process.argv[2];
const targetLang = process.argv[3];

if (textToTranslate && targetLang) {
    translateText(textToTranslate, targetLang)
        .then(res => console.log(res))
        .catch((err) => console.error(`Translation failed: ${err}`));
} else {
    console.error('Please provide text to translate and target language code');
}

Laravel控制器函数代码 #

public function index()
{
    $text = 'I want to try convert my text into hindi language.';
    $targetLang = 'hi';

    $pathToTranslateJS = base_path('translate.js');
    $command = "node " . $pathToTranslateJS . " " . escapeshellarg($text) . " " . $targetLang;

    $process = new Process([$command]);
    $process->run();

    if (!$process->isSuccessful()) {
        throw new ProcessFailedException($process);
    }

    $translatedText = $process->getOutput();
    return  $translatedText;

}

问题原因 #

错误的核心是Process类的参数使用方式错误。将整个命令字符串作为单一元素传入Process数组，导致底层解析命令时出现多余的引号嵌套，触发路径语法错误。

Process类的正确用法是将命令和每个参数拆分为数组的独立元素，而非拼接成完整字符串再传入。当前写法会让系统把整个拼接后的字符串当作一个命令执行，无法识别node是命令、后续内容是参数。

解决方案 #

修改控制器代码，将命令和参数拆分为数组元素传入Process，同时确保执行环境与命令行一致：

public function index()
{
    $text = 'I want to try convert my text into hindi language.';
    $targetLang = 'hi';

    $pathToTranslateJS = base_path('translate.js');
    // 将命令与各参数拆分为数组独立元素
    $process = new Process([
        'node',
        $pathToTranslateJS,
        $text,
        $targetLang
    ]);
    // 设置工作目录为项目根，匹配命令行执行环境
    $process->setWorkingDirectory(base_path());
    $process->run();

    if (!$process->isSuccessful()) {
        throw new ProcessFailedException($process);
    }

    // 去除输出结果中的多余换行符
    $translatedText = trim($process->getOutput());
    return $translatedText;
}

额外优化点 #

• 无需手动使用escapeshellarg()转义参数，Process类会自动处理参数的空格与转义问题
• 添加trim()处理输出结果，避免返回包含多余换行的内容
• 明确设置工作目录，避免因默认工作目录（public）导致的路径或依赖加载问题
