nodejs保存文件，不存在则自动创建目录

            const absolutePath = path.resolve(outputPath);
            const directoryPath = path.dirname(absolutePath);
            if (!fs.existsSync(directoryPath)) {
                try {
                    fs.mkdirSync(directoryPath, { recursive: true });
                    console.log(`目录 ${directoryPath} 创建成功！`);
                } catch (err) {
                    console.error(`创建目录 ${directoryPath} 失败: ${err}`);
                    return;
                }
            }
