如何使 node.js mysql 中的图像文件夹可访问

Question

i wrote an api node.js mysql and i created a folder called images in the same directory with index.js file, but when go to http://localhost:3000/images/bike.png a message says that Cannot GET /images/bike .png

同样的消息也适用于无法 GET /images

我的 index.js 文件

/*  RESTFUL SERVICES BY NODEJS */

var express = require('express');
var mysql = require('mysql');
var bodyParser = require('body-parser');


//connect to mysql
var con = mysql.createConnection({
    host: 'localhost' ,
    user:  'root' ,
    password: '',
    database: 'nodeapp'
})


var app = express();
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.use(express.static('images/'));

//connect to database
con.connect((err) =>{
    if(err) throw err;
    console.log('Mysql Connected...');
  });

/Server listening
app.listen(3000,() =>{
    console.log('Server started on port 3000...');
  });

如何使图像文件夹可访问以及 go 到 bike.png by url

Answer 1

首先，您应该删除app.use(express.static('images/'));中的斜杠。 正如@ptothep 已经提到的。

如果您没有为 static 资产指明路线，则可以从根 URL 访问它们，例如localhost:3000/bike.png 。 如果您希望 map images文件夹到/images然后像这样指示这条路线：

app.use('/images', express.static('images'));
