1 第一段代码
var http=require(‘http‘)
var server=http.createServer(function (request,response) {
???response.setHeader(‘Content-Type‘,‘text/html‘)
???response.write(‘<html><head><meta charset="utf-8"/></head>‘)
???response.write(‘<body><h1>你好 node我要学习你了</h1></body>‘)
???response.end()
})
console.log(‘open http://localhost:8080‘)
server.listen(8080)
2搭建静态服务器
var http = require(‘http‘)
var fs = require(‘fs‘)
var url = require(‘url‘)
var path = require(‘path‘)
var server = http.createServer(function(request, response){
???//获取输入的url解析后的对象
???var pathObj = url.parse(request.url, true);
???//static文件夹的绝对路径
???var staticPath = path.resolve(__dirname, ‘static‘)
???//获取资源文件绝对路径
???var filePath = path.join(staticPath, pathObj.pathname)
???//异步读取file
???fs.readFile(filePath, ‘binary‘, function(err, fileContent){
???????if(err){
???????????console.log(‘404‘)
???????????response.writeHead(404, ‘not found‘)
???????????response.end(‘<h1>404 Not Found</h1>‘)
???????}else{
???????????console.log(‘ok‘)
???????????response.write(fileContent, ‘binary‘)
???????????response.end()
???????}
???})
})
server.listen(8080)
console.log(‘visit http://localhost:8080‘)
