nginx forwards services based on secondary directory and differences with/and without/
When configuring proxy forwarding in nginx, if / is added to the url after proxy_pass, it indicates the absolute root path;
If / is not present, it means the relative path and also passes the matching path part to the proxy.
Specific examples are as follows:
1. Configuration file location belt/ and proxy_pass belt/
server {
listen 80;
server_name ;
#Access the background by accessing the service secondary directorylocation /service/ {
# http://192.168.1.51: The slash behind 8080 is a key. If there is no slash, the service will be passed to the backend node. proxy_pass http://192.168.1.51:8080/;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}That is, if accessed /service/
The actual access to the backend service http://192.168.1.51:8080/
2. Configuration file location with/ and proxy_pass does not
server {
listen 80;
server_name ;
#Access the background by accessing the service secondary directorylocation /service/ {
# http://192.168.1.51: The slash behind 8080 is a key. If there is no slash, the service will be passed to the backend node. proxy_pass http://192.168.1.51:8080;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}That is to access /service/
The actual access to the backend service http://192.168.1.51:8080/service/
3. Configuration file location with / and proxy_pass with secondary directories and /
server {
listen 80;
server_name ;
#Access the background by accessing the service secondary directorylocation /service/ {
# http://192.168.1.51: The slash behind 8080 is a key. If there is no slash, the service will be passed to the backend node. proxy_pass http://192.168.1.51:8080/api/;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}That is, access to/service/
The actual access to the backend service http://192.168.1.51:8080/api/
4. Configuration file location with/ and proxy_pass with secondary directory without/
server {
listen 80;
server_name ;
#Access the background by accessing the service secondary directorylocation /service/ {
# http://192.168.1.51: The slash behind 8080 is a key. If there is no slash, the service will be passed to the backend node. proxy_pass http://192.168.1.51:8080/api;

}
}That is, access to/service/
The actual access to the backend service http://192.168.1.51:8080/
Without/ and proxy_pass with secondary directory without/
