Sometimes you need a proxy.
- Get any from google
- Write your own. That's pretty easy:
const http = require('http');
http.createServer(handler).listen(3000);
function handler(req, res) {
console.log('serve: ' + req.url);
const options = {
hostname: 'example.com',
port: 80,
path: req.url,
method: req.method
};
const proxy = http.request(options, _res => {
_res.pipe(res, {
end: true
});
});
req.pipe(proxy, {
end: true
});
}- Try out this weird thing just for fun.
