答
选项1:如果想要模仿类型:
安装
npm i -S file-type read-chunk
使用
const readChunk = require('read-chunk');
const fileType = require('file-type');
const buffer = readChunk.sync(filePath, 0, fileType.minimumBytes);
console.log(fileType(buffer));
选项2:如果您只需要可能的文件扩展名:
安装
npm i -S image-size
使用
const sizeOf = require('image-size');
console.log(sizeOf(filePath).type);
