Hi @spencergibb ,
Where is the latest version of this code?
Because I was using 2020.0.2 and add implementation("org.springframework.cloud:spring-cloud-starter-netflix-zuul")
But I can not import ZuulFilter() to my code.
Any idea?
Thanks
This seems to be spring cloud zuul. see spring-cloud/spring-cloud-gateway#251
Hello, thanks for examples!
How to modify response data if I need to return it GZipped?
Here and in the ModifyResponseDataStreamFilter
example, the response body length increases. Hence we need to use a HttpServletResponseWrapper
. The PrefixRequestEntityFilter
example covers this, I feel the response side examples should also do this. Will be happy to send a PR.
First let me figure out how to do this.
Hello Spencer, hello community,
I am having a use case I have to complete, and would like your help on the gateway.
Requirement: Let's say I am having a micro service called myService, which exposed /getData and /saveData.
Now, I am deploying this myService to multiple locations, like: myServiceAWS, myServicePCF, myServiceAzure, etc...
Is it possible with Zuul, or Spring Cloud Gateway, to route to ALL of them based on the route?
If I do something like
zuul.ignoredServices=*
zuul.routes.myService.path=//getData/
zuul.routes.myService.url=http://myServiceAWS:8080,http://myServicePCF:8081,http://myServiceAzure:8082
That results in an error.
If I do something like
zuul.routes.myService.path=//getData/
zuul.routes.myService.url=http://myServiceAWS:8080/
zuul.routes.myService.path=//getData/
zuul.routes.myService.url=http://myServicePCF:8081/
Always only the first one is taken into account.
Could you please advice if it is possible to route to ALL with Zuul (Or Spring Cloud Gateway)?
Or maybe, a way to do it with filters please?
Thank you very much
