我正在尝试使用直接的香草Node.js
,除了教育目的所需的框架之外没有框架。我目前有这个设置:
var fs = require('fs'),
jade = require('jade');
function compile(dirPath, res) {
var filePath = __dirname + dirPath;
fs.readFile(filePath, 'utf8', function(err, fd) {
var fn = jade.compile(fd, { filename: filePath, pretty: true});
res.write(fn());
res.end();
});
}
exports.compile = compile;
在要求请求的页面时调用,如下所示:
var jadec = require('./jadecompile');
function start(res, postData) {
res.writeHead(200, {"Content-Type": "text/html"});
var cpage = '/staticpages/index.jade',
page = jadec.compile(cpage, res);
}
页面加载很棒,我将其作为我的观察源:
<!DOCTYPE html>
<html>
<head>
<title>Hello!</title>
<link rel="text/css" href="assets/css/bootstrap.css">
</head>
<body>
<div class="hero-unit">
<p>Hello This Is A Test</p>
</div>
</body>
</html>
但是css根本不起作用,我一直试图谷歌它,但每个答案似乎都使用快递或其他东西,但我想学习如何做到尽可能香草,所以我的问题是,我如何处理* .css以便正确加载css,当我点击视图源中的href
链接时,它会加载我的404页面,而不仅仅是css文件的纯文本。谢谢!

我设法通过创建一个处理静态页面的函数来解决我的问题,例如.css或.js,如下所示:
var http = require('http'),
url = require('url'),
path = require('path');
fs = require('fs');
// ADDED THIS FUNCTION HERE -----------------------------------------------------
function handleStaticPages(pathName, res) {
var ext = path.extname(pathName);
switch(ext) {
case '.css':
res.writeHead(200, {"Content-Type": "text/css"});
fs.readFile('./' + pathName, 'utf8', function(err, fd) {
res.end(fd);
});
console.log('Routed for Cascading Style Sheet '+ pathName +' Successfully\n');
break;
case '.js':
res.writeHead(200, {"Content-Type": "text/javascript"});
fs.readFile('./' + pathName, 'utf8', function(err, fd) {
res.end(fd);
});
console.log('Routed for Javascript '+ pathName +' Successfully\n');
break;
}
}
// ADDED THIS FUNCTION HERE -----------------------------------------------------
function start(route, handle) {
function onRequest(req, res) {
var postData = "",
pathName = url.parse(req.url).pathname;
console.log('Request for ' + pathName + ' received.');
req.addListener('data', function(data) {
postData += data;
console.log('Received POST data chunk ' + postData + '.');
});
req.addListener('end', function() {
var pathext = path.extname(pathName);
if (pathext === '.js' || pathext === '.css') {
handleStaticPages(pathName, res);
} else {
console.log('--> Routing only the view page');
route(handle, pathName, res, postData);
}
});
}
http.createServer(onRequest).listen(4000);
console.log('Server is now listening at: http://127.0.0.1:4000 .');
}
exports.start = start;

为了处理.css和其他静态文件,需要有一个文件流。您可以使用以下内容,而不是使用switch语句。
var stream = fs.createReadStream(path); //创建文件流 stream.pipe(RES); //传输文件
