Express + Node.js Can't get Image to load

问题

Very new to MEAN Stack and I'm using Brackets to edit .ejs views for a simple form app using Express tutorial. I'm trying load a static image and it just won't load. I'm getting GET /public/ggcbear.jpg 404 from app.js (terminal). I also created a image.ejs views to handle the load...but thats not working. My .jpg is listed in the folder: public. What syntax is wrong in my code/.ejs files?

Part of my app.js

    var http = require("http");
    var path = require("path");
    var express = require("express");
    var logger = require("morgan");
    var bodyParser = require("body-parser");

   // Make an express app
   var app = express();

   app.set("views", path.resolve(__dirname, "views"));
   app.set("view engine", "ejs");


   //adding static functionality for images
   app.use(express.static('public'));


   // Renders the "image" page (at views/index.ejs) when GETing the URL
   app.get("/image", function(request, response) {
    response.render("image");
   });

   //etc...

my header.ejs

    <!-- This header will appear at the top of every page -->
        <!DOCTYPE html>
         <html> 
         <head>
         <meta charset='utf-8'>
          <title>Express Guestbook</title>
          <!-- Loads Twitter's Bootstrap CSS from the Bootstrap CDN -->
          <!-- http://getbootstrap.com/ -->

          <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
          </head>
          <body class ="container">

         <!-- my image tag -->
          <div>
            <img src="/public/ggcbear.jpg">
         </div>

        <h1>
            Express Guestbook
            <a href="/new-entry" class="btn btn-primary pull-right">
                Write in the guestbook
            </a>
        </h1> 
        </body>    
        </html>

my image.ejs

<% include header %>

    <div>
        <h3><img src="/ggcbear.jpg", alt="Testing Image")</h3>
    </div>
 <% include footer %>

回答1:

Using the following static middleware:

app.use(express.static('public'));

and the following folder structure:

.
├── app.js
├── public
│   └── images
│       └── ggcbear.jpg
└── view
    ├── header.ejs
    └── image.ejs

your ggcbear.jpg will serve from /images/ggcbear.jpg:

<img src="/images/ggcbear.jpg">
