Node.js提供HTML，但无法在提供的页面中加载脚本文件 [英] Node.js serve HTML, but can't load script files in served page
问题描述
我正在尝试使用mongoDB数据库和Node.js + express创建一个小的登录页面。我是Node.js的新手，所以解决方案可能比我想象的要容易。
问题是：当我连接到服务器页面时提供HTML文件时，我无法使用html文件中引用的JavaScript文件。我该如何解决？
Ps index.html和client.js文件都位于名为client的文件夹中。
i'm trying to make a little login page using a mongoDB database and Node.js + express. I'm new to Node.js so maybe the solution is easier than i thought. The problem is: when i serve the HTML file when connecting to the server page, i can't use the JavaScript file referenced in the html file. How can i fix it? P.s the index.html and client.js files are all located in a folder named "client".
代码：
var express = require('express');
var path = require('path');
var app = express();
app.use(express.static(__dirname + 'client'));
app.get('/', function(req, res) {
res.sendFile(path.join(__dirname + '/client/index.html'));
});
HTML文件：
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Login</title>
<meta name="description" content="Login Page">
<meta name="author" content="AlbertoCoder">
<script src="/client/client.js"></script>
</head>
<body>
</body>
</html>
推荐答案
你可以使用它，但你需要通过有效路径从您的服务器提供该javascript文件。
You're able to use it, but you need to serve that javascript file from your server through a valid path.
在您的HTML中，您试图从 / client /中检索javascript文件client.js
In your HTML you're trying to retrieve the javascript file from /client/client.js
这里的提示是：
想象一下服务器的以下URL http：// myserver：8080 /
Imagine the following URL of your server http://myserver:8080/
现在，您的HTML是试图通过 http：// myserver：8080 / client / client.js检索js文件
Now, your HTML is trying to retrieve the js file through http://myserver:8080/client/client.js
当你可以看到，您的服务器没有提供该资产，因此您将无法检索该js文件。
As you can see, your server is not serving that assets, thus you won't be able to retrieve that js file.
执行以下操作：
app.get('/client/client.js', function(req, res) {
res.sendFile(path.join(__dirname + '/client.js'));
});
app.get('/', function(req, res) {
res.sendFile(path.join(__dirname + '/client/index.html'));
});
