如何列出 node.js 文件夹中的图像

Question

我正在尝试使用 node express pug 模块列出该文件夹中的文件，但出现错误，例如

错误：ENOENT：没有这样的文件或目录，stat '/home/jarvis/Desktop/visageSDK-HTML5/doc/static/public/uploads/0' 在 Object.statSync (node:fs:1536:3)

以下代码是如何从节点服务器获取图像或其他 static 文件的示例。

const express = require('express'); 
const app = express();
const PORT = 3000;                 

app.use(express.static('public')); 
app.use('/images', express.static('images'));
 
app.listen(PORT, () => {
  console.log(`Running server on PORT ${PORT}...`);
})

希望，这回答了你的问题
