nginx: how to rewrite the url to use www and https - nginx

Question

How to rewrite the url to use www and https all the time?
// The url can have https but not www
https://example.com
// The url can have www but not https
http://www.example.com
// The url can have neither https, neither www
http://example.com
=> rewrite to https://www.example.com
I already use the following to add https to all requests but what about http? Is there an efficient way of adding it?
server {
listen 80;
listen [::]:80;
return 301 https://$host$request_uri;
}
Thanks

Answer 1

Create 2 server blocks to handle the exceptions and 1 server block for the usual stuff.
server {
listen 80;
server_name www.domain.com
domain.com;
return 301 https://www.domain.com$request_uri;
}
server {
listen 443 ssl;
server_name domain.com;
return 301 https://www.domain.com$request_uri;
}
server {
listen 443 ssl;
server_name www.domain.com;
#
# The usual stuff..
#
}

TanHongTat answers is good but you have to take into account the default server behavior of nginx. If no server block matches, it will take the first one even though you defined server_name.
Also, do not forget to add the ssl certificate and key even for the block with only a return.
I ended up doing the following:
# Default server for http
server {
listen 80;
listen [::]:80;
return 301 https://www.domain.com$request_uri;
}
# Default server for https
server {
listen 443;
return 301 https://www.domain.com$request_uri;
ssl on;
ssl_certificate /..../ssl_certificate.crt;
ssl_certificate_key /..../ssl_certificate.key;
# Disable SSLv3 vulnerability
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
}
server {
listen 443;
server_name www.domain.com;
ssl on;
ssl_certificate /..../ssl_certificate.crt;
ssl_certificate_key /..../ssl_certificate.key;
# Disable SSLv3 vulnerability
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
#
# The usual stuff..
#
}
