Is this possible?
User enters https://mywebsite.com/location/any-path
Nginx runs https://mywebsite.com/location/
URL displays https://mywebsite.com/location/any-path
Is there a particular name for this type of action also?
You can use nginx redirection here -
location = /location/any-path {
return 301 /location;
}
You want to proxy_pass the request to another url and then proxy_redirect to alter the url displayed to the client.
Something like this:
location ~ /location/(.+) {
resolver 8.8.8.8;
proxy_pass https://mywebsite.com/location/index.php;
proxy_redirect /location/ /location/$1/;
}

Can I set a variable with an URL returned by a proxy? ... I want to avoid to run Java, PHP, Python etc. Need somethong simple and faster.
Note, to answer comments: "... an URL returned by a proxy" = a microservice that is a black-box returning the URL. Any URL, can be aleatory or function of inputs (passed to the proxy).
If it is possible, how to?
This is fine on my NGINX server, it is returning a string with the necessary URL.
location /_test {
rewrite ^/_test/(.*) /$1 break;
proxy_pass http://127.0.0.1:3000;
}
(here $1 is the input and 127.0.0.1:3000 the black-box microservice)
... How to redirect as return 301 $theNewUrl? Imagining something (illustrative and wrong of course) as
location /_test {
rewrite ^/_test/(.*) /$1 break;
set theNewUrl = proxy_pass(http://127.0.0.1:3000/$1);
return 301 $theNewUrl;
}
To redirect base on path on Ningx, try this:
example.com is your base domain.
server {
server_name myDomain;
location /_test/hello/ {
proxy_pass http://google.com/;
}
location /_test/bye/ {
proxy_pass http://stackoverflow.com/;
}
}
Example:
HTTP request to http://myDomain/_test/hello/$1 will be translated to: http://google.com/$1 you can use it with ports or whatever you want.
I need to get the parameter from an URL, for example, abc=MY_STRING:
https://my-address/test?abc=MY_STRING
And at the reverse proxy (my-address), is configured like this:
location /test?(.*) {
proxy_pass http://local-server:1234/test?$args
}
but it is not working.
I tried another configuration:
location /test?(.*) {
proxy_pass http://local-server:1234/test?$1
}
but not worked too.
You cannot match the query string part of the URI with a location or rewrite statement, as it is not part of the normalized URI.
But you don't need to. The URI (complete with query string) will be passed upstream
unless you redirect it using a rewrite or try_files statement.
For example:
location /test {
proxy_pass http://localhost:1234;
}
The URI /test?abc=MY_STRING will match the location and be passed to localhost:1234 exactly the same. See this document for more.
I need to set proxy_pass for the below url pattern.
location ~ ^/hosts/bu/(.*)/app/(.*)$ {
proxy_pass http://appserver.cnma.com:3000/hosts/bu/$1/app/$2;
}
When I try with the URL it does not pass the second parameter correctly. Please let me know where I am going wrong.
Orig docs say:
If proxy_pass is specified without a URI, the request URI is passed to the server in the same form as sent by a client when the original request is processed, or the full normalized request URI is passed when processing the changed URI:
location /some/path/ {
proxy_pass http://127.0.0.1;
}
So there is enough:
proxy_pass http://appserver.cnma.com:3000$request_uri;
you can use named capture in nginx while using regular expressions
location ~ ^/hosts/bu/(.*)/app/(.*)$ {
proxy_pass http://appserver.cnma.com:3000/hosts/bu/$1/app/$2;
}
You can modify block to below like this
location ~ ^/hosts/bu/(?<loc1>.+)/app/(?<loc2>.+)$ {
proxy_pass http://appserver.cnma.com:3000/hosts/bu/$1/app/$loc2;
}
I have a url http://foo.com/banana and I have another url http://foo.com/banana?a=1&b=2
I like that all /banana routes are handled by my local nginx, but I'd like any banana routes with GET params to be proxied to http://bar.com
so:
http://foo.com/banana -> http://foo.com/banana
http://foo.com/banana?a=1 -> (proxy) -> http://bar.com/banana?a=1
I should note this is not for production. I'm trying to redirect api calls to redirect to another server during development.
I've tried to do an 'if args' block but I can't do a proxy_pass in an if block.
I thought about doing a rewrite of:
http://foo.com/banana?a=1 -> http://foo.com/proxy?a=1
location /proxy {
proxy_pass http://bar.com;
}
But I don't have the right logic for above because bar.com is expecting the /banana route.
Any ideas?
Since this is not for production, you could stick with your original "if" solution. You only need to escape from the "if" block to be able to proxy_pass, which can be easily done with the traditional trick:
location /banana {
error_page 418 = #good_old_fallback;
if ($args) {
return 418;
}
}
location #good_old_fallback {
proxy_pass http://bar.com;
}
Your idea of using another location will also work, so if you prefer it better, you can go with something like this:
location /banana {
if ($args) {
rewrite ^/banana(.*)$ /proxy$1 last;
}
}
location /proxy {
internal;
rewrite ^/proxy(.*)$ /banana$1 break;
proxy_pass http://bar.com;
}
I've learned how to pass localhost:9292 to localhost/foo with the following directive:
location /foo {
proxy_pass http://localhost:9292;
}
but I want do something like
foo.localhost -> localhost:9292
Is there a way I can do that?
If foo.localhost is your sub domain name and you want to proxy pass sub-domain to main-domain, you can use proxy_pass and you can learn a little more about server directive if needed. An example:
server {
listem 8080;
host sub.main.com;
...
location / {
proxy_pass http://main.com;
break;
}
}
server {
listen 8081;
host main.com;
...
location / {
//do something
}
}
This is proxy pass, means when access sub.main.com, actually it finally dealt by main.com, but the client side still shows sub.main.com. If you want client side shows main.com, here should use redirect but not proxy_pass.
