问题
I have an express app freshly created using express appName.
I've changed the port to 443.
The domain is under CloudFlare's proxy with SSL enabled.
When I go to the website though, I get the CloudFlare page Web server is down instead of seeing the express index page.
How can I make Express work with CloudFlare's SSL?
回答1:
There are two options:
- You need to alter your app such that it is able to accept HTTPS connections instead of HTTP. You can do this by using the HTTPS library instead of HTTP.
- You can switch to Flexible SSL instead of Full, but this is not recommended for a lot of applications as it means the connection from Cloudflare's Edge to your Origin is unencrypted.
