[英]Why isn't my public folder fetching files for '/' URL in my NodeJS App?
I am trying to place static files in my public folder such as the html,css and js files but they won't fetch to the get url ('/'). 我试图将静态文件放置在我的公共文件夹中,例如html,css和js文件,但它们不会获取到获取URL('/')。 Here is my folder structure
这是我的文件夹结构
app.js
node_modules
--express
package.json
public
--style.css
My app is: 我的应用是:
var express = require('express');
var app = express();
var port = process.env.PORT || 3000;
app.use('/assets', express.static(__dirname + '/public'));
app.get('/', function(req, res){
res.send('<html><head><link href=assets/style.css type=text/css rel=stylesheet/></head><body><h1>Hello World</h1></body></html>');
});
app.get('/person/:id', function(req, res){
res.send('<html><head></head><body><h1>Person: ' + req.params.id + '</h1></body></html>');
});
app.get('/api', function(req, res){
res.json({ firstname: 'John', lastname: 'Doe' });
});
app.listen(port);
Style code is: 样式代码为:
style.css:
body {
font-family: Arial, Helvetica, sans-sarif;
}
Your problem is, because 你的问题是,因为
<link href=assets/style.css type=text/css rel=stylesheet/>
is equal to 等于
<link href=assets/style.css type=text/css rel="stylesheet/">
If you don't use quotes then the value is terminated by one of the following characters: "
, '
, =
, >
, <
, or `
(See W3C: 4.4. Attributes for more details). As of that your value is terminated by the >
value is stylesheet/
. 如果不使用引号,则该值将以下列字符之一终止:
"
, '
, =
, >
, <
或`
(请参见W3C:4.4。属性以获取更多详细信息)。通过>
值是stylesheet/
。
Because of that the rel
of your link
is stylesheet/
instead of stylesheet
and thats why no stylesheet is loaded. 因此,
link
的rel
性是stylesheet/
而不是stylesheet
,这就是为什么不加载样式表的原因。
So either you have to add a space between stylesheet
and /
: 因此,要么必须在
stylesheet
和/
之间添加一个空格:
<link href=assets/style.css type=text/css rel=stylesheet />
or you need to use quotes. 或者您需要使用引号。
您可以将“ public”重命名为“ assets”,然后使用...
app.use(express.static('assets'));
There is syntax error in your HTML statement that links to the CSS file. HTML语句中存在链接到CSS文件的语法错误。 You forgot to enclose the values in double quotes.
您忘记将值括在双引号中。
Please use the following format: 请使用以下格式:
<link rel="stylesheet" type="text/css" href="assets/style.css">
If you are using ES6 supporting Node.JS then you can use the back-ticks(``) to better format the inline HTML code like: 如果您正在使用支持Node.JS的ES6,则可以使用back-ticks(``)更好地格式化内联HTML代码,例如:
app.get('/', function(req, res){
res.send(`
<html>
<head>
<link rel="stylesheet" type="text/css" href="assets/style.css">
</head>
<body>
<h1>Hello World</h1>
</body>
</html>`
);
});
