QUESTION
is there a way in nginx to do something based on if the request body has a string or not? I am sure i can do it with using Lua module.. I am try to find out if there is a way using nginx alone.
I am hoping something like below will work.
...ANSWER
Answered 2020-Oct-23 at 11:25I think it should work, however it needs to be tested. In practice I used $request_body
only for logging, not sure if it is available at the rewrite stage of request processing. Here is an official description which says:
The variable’s value is made available in locations processed by the
proxy_pass
,fastcgi_pass
,uwsgi_pass
, andscgi_pass
directives when the request body was read to a memory buffer.
Additionally, you don't need those capture groups to check a variable for substring presence if you don't use them later (in fact you just wasting resources to keep them in memory), just if ($request_body ~* "specialstudent") { ... }
should be enough.
Update
Here is another approach that has more chances to work since proxy_add_header
directive is definitely executed later than the rewrite stage of request processing:
QUESTION
We are using AKS (Azure Kubernetes Service) for managed Kubernetes clusters and for the biggest part we are happy with the benefit the platform brings but we face some issues as well.
On AKS if you host a service of LoadBalancer type it automatically creates a new dynamic IP address (Azure resource) and assigns it to the service. This is not very optimal if you want to whitelist and simply does not make sense hence we switched to Nginx ingress controller (no particular reason to choose Nginx). We have a lot of apps - APIs, SPAs, 1 ingress controller for the whole cluster and separate cluster per environment - QA/Sta/Prod etc.. So we need to manage routing somehow and the ingress path parameter felt like the way to go. Example:
http://region.azurecloud.com/students/
http://region.azurecloud.com/courses/
where students and courses are the ingress paths and then you can add /api/student for example to access a particular API. The result would be http://region.azurecloud.com/students/api/student/1 which is not perfect but does the job for now.
This is how the ingress looks like:
...ANSWER
Answered 2020-Jun-16 at 00:44The way I usually deal with this for SPAs is to have different hostnames for each SPA. For example, in a non-production cluster having two SPAs named student-portal
and teacher-portal
, I would create DNS records for student-portal.mydomain.com
, teacher-portal.mydomain.com
pointing to the public IP of the cluster load balancer.
Include the domain name in the rules of the ingress resource.
I find this is the most efficient way and avoids needing to deal with each SPA framework individually.
