Nginx uses the proxy_pass directive to configure the method of requesting uri replacement
This article introduces the relevant knowledge of "nginx uses proxy_pass instructions to configure the method of requesting uri replacement". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
Configure the location of nginx. In the upstream configuration after proxy_pass, if the normal configuration is the upstream service address and port, the request uri will be forwarded unchanged. If it is configured with uri, it will be replaced and forwarded according to the configured uri.
Normal configuration:
Location = / uri/uri {
Proxy_pass http://upstream1;
}
Upstream upstream1 {
Server 10.0.0.1:80 weight=10
}
The client sends the request: the upstream request for http://nginx_ip:nginx_port/uri/uri, nginx is: http://10.0.0.1:80/uri/uri.
Add uri to the configuration:
Location = / uri/uri {
Proxy_pass http://upstream1/test/test;
}
Upstream upstream1 {
Server 10.0.0.1:80 weight=10
}
The client sends the request: the upstream request for http://nginx_ip:nginx_port/uri/uri, nginx is: http://10.0.0.1:80/test/test.
The current requirement is that the other party pushes data to us, they are fixed uri, they ask us to adapt their interface, and they only configure our ip and port number. On the other hand, our application is deploying tomcat. If it is implemented in the application layer, we need to modify the server configuration of tomcat and the interface uri configured in the service, which is troublesome. Match the uri arbitrarily in the above way to adapt to the back-end service, which is easier.
