我想运行一个非常简单的HTTP服务器。对example.com的每个GET请求都应该得到index.html,但作为一个常规的HTML页面(即,与阅读普通网页时的体验相同)。
使用下面的代码,我可以读取index.html的内容。我如何服务index.html作为一个普通的网页?
var http = require('http');
var fs = require('fs');
var index = fs.readFileSync('index.html');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end(index);
}).listen(9615);
下面的一个建议很复杂,需要我为我想使用的每个资源(CSS、JavaScript、图像)文件写一个get行。
我如何能提供一个单一的HTML页面与一些图像,CSS和JavaScript?
我也可以推荐SugoiJS,它很容易设置,并提供了一个快速开始编写的选项,有很好的功能。

它具有请求处理装饰器、请求策略和授权策略装饰器。
例如:
import {Controller,Response,HttpGet,RequestParam} from "@sugoi/server";
@Controller('/dashboard')
export class CoreController{
constructor(){}
@HttpGet("/:role")
test(@RequestParam('role') role:string,
@RequestHeader("role") headerRole:string){
if(role === headerRole )
return "authorized";
else{
throw new Error("unauthorized")
}
}
}
你不需要快递。你不需要联系。Node.js执行http native。你所需要做的就是根据请求返回一个文件:
var http = require('http')
var url = require('url')
var fs = require('fs')
http.createServer(function (request, response) {
var requestUrl = url.parse(request.url)
response.writeHead(200)
fs.createReadStream(requestUrl.pathname).pipe(response) // do NOT use fs's sync methods ANYWHERE on production (e.g readFileSync)
}).listen(9615)
一个更完整的例子,确保请求不能访问基目录下的文件,并进行适当的错误处理:
var http = require('http')
var url = require('url')
var fs = require('fs')
var path = require('path')
var baseDirectory = __dirname // or whatever base directory you want
var port = 9615
http.createServer(function (request, response) {
try {
var requestUrl = url.parse(request.url)
// need to use path.normalize so people can't access directories underneath baseDirectory
var fsPath = baseDirectory+path.normalize(requestUrl.pathname)
var fileStream = fs.createReadStream(fsPath)
fileStream.pipe(response)
fileStream.on('open', function() {
response.writeHead(200)
})
fileStream.on('error',function(e) {
response.writeHead(404) // assume the file doesn't exist
response.end()
})
} catch(e) {
response.writeHead(500)
response.end() // end the response so browsers don't hang
console.log(e.stack)
}
}).listen(port)
console.log("listening on port "+port)
从w3schools
创建一个节点服务器来服务任何被请求的文件是很容易的,你不需要为它安装任何包
var http = require('http');
var url = require('url');
var fs = require('fs');
http.createServer(function (req, res) {
var q = url.parse(req.url, true);
var filename = "." + q.pathname;
fs.readFile(filename, function(err, data) {
if (err) {
res.writeHead(404, {'Content-Type': 'text/html'});
return res.end("404 Not Found");
}
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(data);
return res.end();
});
}).listen(8080);
http://localhost:8080/file.html
将从磁盘上提供file.html
var http = require('http');
var fs = require('fs');
var index = fs.readFileSync('index.html');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/html'});
// change the to 'text/plain' to 'text/html' it will work as your index page
res.end(index);
}).listen(9615);
我想你是在找这个。在index.html中,简单地用普通的html代码填充它-无论你想在上面渲染什么,比如:
<html>
<h1>Hello world</h1>
</html>
