Sling Filter with multiple resource type and specific query parameter in request

Hello,

Below are two points I'm trying to cover via my Sling filter but seems not functional properly.

1. I want my filter to be chained on specific resource types e.g.  /apps/a/p1 ,  /apps/a/p2 , /apps/a/p3

2. I want my filter to be chained only on specific query parameters in request (e.g.  https://helloworld.xyz/parent/page-1.html?q=...., https://helloworld.xyz/parent/page-2.html?q=....,   https://helloworld.xyz/parent/page-3.html?q=.... )etc.

 

Below are current state of my filter

1. Filter Scope is of "Request"

2. Tried multiple resource types as below syntax; Assume resource types of page-1 is " /apps/a/p1", resource types of page-2 is " /apps/a/p2"  & resource types of page-3 is " /apps/a/p3".  Also assume content path of pages are as  /content/parent/page-1 etc.

@Component (service = Filter.class, property = {
  EngineConstants.SLING_FILTER_SCOPE + "=" + EngineConstants.FILTER_SCOPE_REQUEST,
  EngineConstants.SLING_FILTER_METHODS + "=" + "GET",
  EngineConstants.SLING_FILTER_EXTENSIONS + "=" + "html",
  EngineConstants.SLING_FILTER_PATTERN + "=" + "/content/(parent)/.*",
  EngineConstants.SLING_FILTER_RESOURCETYPES + "=['/apps/a/p1','/apps/a/p2',/apps/a/p3']"
})

But I'm unable to register (tried with comma separated values also) and also when i'm using @SlingServletFilter annotation, same issue is taking place.

@SlingServletFilter(scope = { SlingServletFilterScope.REQUEST},
  resourceTypes = {"/apps/a/p1","/apps/a/p2","/apps/a/p3"},
  pattern = "/content/(parent)/.*",
  extensions = {".html"},
  methods = {"GET"})

Hi,

Can you check.

https://sling.apache.org/documentation/the-sling-engine/filters.html 

 

I have achieve this in the past using regex pattern.

    Hi Arun, 

     

    I tried with these two patterns for resourceTypes -- i) one with absolute path  "/apps/a/(p1|p2|p3)"  and ii) with relative path "a/(p1|p2|p3)"; Do I need to try something different?

      Hi,

      Not sure if this will work with resourceType because the resourcetype argument is for component scope. I am not 100% sure but I used this when I need to intercept the component rendering 

      e.g. https://github.com/arunpatidar02/aem63app-repo/blob/master/java/XFFilter.java

        Hi @djsarkar 

        Is your resourceType getting resolved? Ignore below If not. (resourceType is an relative path just double check)

        @Component (service = Filter.class, property = {
          EngineConstants.SLING_FILTER_SCOPE + "=" + EngineConstants.FILTER_SCOPE_REQUEST,
          EngineConstants.SLING_FILTER_METHODS + "=" + "GET",
          EngineConstants.SLING_FILTER_EXTENSIONS + "=" + "html",
          EngineConstants.SLING_FILTER_PATTERN + "=" + "/content/(parent)/.*",
          EngineConstants.SLING_FILTER_RESOURCETYPES + "=" + "/apps/a/p1",
          EngineConstants.SLING_FILTER_RESOURCETYPES + "=" + "/apps/a/p2",
          EngineConstants.SLING_FILTER_RESOURCETYPES + "=" + "/apps/a/p3",
        })

        Then get queryString parameter from the URL to check and filter chain.

          Hi Santosh, 

          Thanks for the response. I tried multiple resource types the way you mentioned. But seems it didn't work. Also I tried with absolute and relative path as well. and at last, I tried with regex pattern as -  "/apps/a/(p1|p2|p3)" but got no luck.

          if I just remove the page resourceTypes and keep rest fields, it's working fine.

            @djsarkar 

            It seems OOTB, there's no possibility of associating Sling Filters with Sling Resource Types. Found one workaround here to achieve it: https://stackoverflow.com/questions/16886232/does-sling-allow-component-filters-configured-to-target-only-certain-resource-ty#comment24398528_16893230

             

            Hope that Helps!

              Hi @djsarkar - 

              Have you tried the relative paths with SlingServletFilter annotation like below?

              @SlingServletFilter(scope = { SlingServletFilterScope.REQUEST},
                resourceTypes = {"a/p1","a/p2","a/p3"},
                pattern = "/content/(parent)/.*",
                extensions = {".html"},
                methods = {"GET"})
