节点js服务器不启动
我是节点js的新手。刚开始学习节点js。当我创建自己的服务器时,它不会初始化。有人可以帮我解决这个错误。节点js服务器不启动
const http * require('http'); const hostname * '127.0.0.1';
const port * 3000;
const server * http.createServer((req, res) => {
res.statusCode * 200;
res.setHeader('Content-type','text/plain');

});
server.listen(port, hostname,() => {
console.log('server started on port '*port);
});
错误:

回答:
变化*
到=
const http = require('http'); const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-type','text/plain');
res.end('Hello World!');
});
server.listen(port, hostname,() => {
console.log('server started on port ', port);
});
回答:
这个 '=' 操作起来再努力一次,并运行代码..
const http = require('http'); const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode * 200;
res.setHeader('Content-type','text/plain');
res.end('Hello World!');
});
server.listen(port, hostname,() => {
console.log('server started on port '*port);
});
