使用Express在Node JS中路由问题

Question

I have a godaddy domain being redirected to an instance of EC2 with an elastic IP. on instance there runs my NodeJS on port 5000. im redirecting 80 to 5000( till here everything works fine). In express i have a route say '/Calculate/:Type', which is visited when some caculate button is pressed. ideally the when button is pressed a request to server should go like http://example.com/calculate/3 but here is goes http://example.com//calculate/3 an extra / before caculate ruins the entire route. can someone please tell me why is it happening?

Answer 1

Try adding a period in front of /Calculate/:Type so

'./Calculate/:Type' in your express route

Ahh so it seems like you may be hitting a CORS error. Is your webserver and dataserver on the same url?

• Best option : Put the node instance serving your app on yourdomain.com, and make your api endpoint api.yourdomain.com/Calculate/:Type
• Other Option: exposing yourself to security risks by adding a 'Access-Control-Allow-Origin = *' in the header of your response
• Other Option: expose yourself to security change your settings in htaccess to allow all, or the specific domain
