express.js静态无法识别已定义的“公用”文件夹

Question

I have the following dir setup;

**app** **controllers** *index.server.controller.js* **models** **routes** *index.server.routes.js* **views** *index.ejs* **config** **env** *config.js* *express.js* **public** **css** **img** *logo.jpg* **js** *server.js* *package.json*

Inside express.js, I'm loading the static directory using the following;

//app.use(express.static(__dirname + '\\..\\public\\') - also attempted
app.use(express.static('./public'));

I'm then serving index.ejs, which contains the following snippet;

<img src="img/logo.jpg" alt="Logo"/>

However, this always results in a 404 being returned on the image itself.

C:\\nodejs>node horizontal/server Localhost running on port 3000 GET / 304 13.763 ms - - GET /img/logo.jpg 404 4.372 ms - 25

As seen above, I've attempted giving a strict __dirname path (as I had to do with setting up the path to views, as seen below) - and also attempted just inserting public/img/logo.jpg in order to see it getting served up.

Views, as it works;

app.set('views', __dirname+'\\\\..\\\\\\\\app\\\\views\\\\'); app.set('view engine', 'ejs');

Would anyone have any ideas as to why express isn't seeing the public folder, or serving static content from it?

Note that my Dev env is Windows8.1.

Answer 1

You should use the path module to do that.

var path = require('path');

With an app directory looking like below

You would just access the public folder like this:

app.use(express.static(path.join(__dirname, 'public')));

Hope that helps!
