nodejs之http模組
nodejs伺服器端
const http = require('http');
const server = http.createServer(function (req, res) {
res.writeHead(200, {
'content-type': 'text/plain'
});
res.end('hello node.js');
});
server.listen(3000, function () {
console.log('listening port 3000')
})
或者
const http = require('http');
const server=new http.Server();
server.on('request',function (req, res) {
res.writeHead(200, {
'content-type': 'text/plain'
});
res.end('hello node.js');
});
server.listen(3000, function () {
console.log('listening port 3000')
})
const http = require('http');
const server = http.createServer(function (req, res) {
let data = '';
req.on('data', function (chunk) {
data += chunk;
});
req.on('end', function () {
let method = req.method;
// headers是物件，需要轉成字元才能打印出來
let headers = JSON.stringify(req.headers);
let url = req.url;
let httpVersion = req.httpVersion;
res.writeHead(200, {
'content-type': 'text/html'
});
let dataHtml = '<p>data:' + data + '</p>'
let methodHtml = '<p>method:' + method + '</p>'
let headersHtml = '<p>headers:' + headers + '</p>'
let urlHtml = '<p>url:' + url + '</p>'
let httpVersionHtml = '<p>httpVersion:' + httpVersion + '</p>'
let resData = dataHtml + methodHtml + headersHtml + urlHtml + httpVersionHtml
res.end(resData)
})
})
server.listen(3000, function () {
console.log('listening port 3000')
})
客戶端
const http=require('http');
let reqData=''
http.request({
'host':'192.168.3.72',
'port':'3000',
'method':'get'
},function(res){
res.on('data',function(chunk){
reqData+=chunk;
});
res.on('end',function(){
console.log(reqData);
})
}).end();
先把伺服器啟動，然後再啟動客戶端，客戶端通過get請求伺服器資料。
const http=require('http');
let reqData=''
http.get({
'host':'192.168.3.72',
'port':'3000'
},function(res){
res.on('data',function(chunck){
reqData+=chunck
});
res.on('end',function(){
console.log(reqData)
})
}).end();
tip：響應的操作都是在get請求中的。
const http = require('http');
let reqData = '';
let option = {
'host': '192.168.3.72',
'port': '6000'
}
const req = http.request(option);
req.on('response', function (res) {
res.on('data', function (chunk) {
reqData += chunk;
});
res.on('end', function () {
console.log(reqData)
});
});
