I'm learning by myself to use AEM, I'm using metadata for building my own forms for assets.
I need to extract the assets' metadata, and print them on my page, I'm new in AEM and i don't know how to do it. I'm thinking about create a component by I don't know what i sholud write inside
I had worked on a similar use case, so I am assuming this can help you.
Usecase : An asset is displayed in page and it will have link MetadataInfo. Once I click on the MetadataInfo link, it will re-direct to metadatainfo page which will display all the metadata information of the asset.
Solution :
Once the link is clicked it redirects to url of the metadatinfo page appended with parameter "assetpath" containing the asseturl.
Created a servlet which will get the parameter "path" containig the asseturl as string and convert it to a resource. Will resolve it to resource till the metadata node of the asset.("asseturl"/jcr:content/metadata)
By Value map got all the properties of metadata and created hashmap storing all the metadata properties as Key:Value pair
Create a Metadatainfo component which is placed in Metadatinfo page. This component dispalys the metadata values as Key:Value by data-sly list.

I am using AEM API in my automation. We published a file from workfront to AEM. That file have multiple information:
1. Basic
2. Test1
3. test2
4. etc
When I hit the api:
/api/assets/..../abc.pdf.json
I am getting very less information under the properties and metadata section. (In short, it does not have Test1, Test2 and other tab information)
Is there any way to fetch all these from aem API's? It will reduce my overhead to validate these details from UI Automation.
First of look checkout the metadata nodes of file for the desired data to be present. I would rather prefer writing a custom servlet in AEM which takes in path parameter as an asset path and gives back the response back in desired format.
I figured it out.
The following API returns all the JCR content in API response:
<baseURL>/content/dam/path to that file.-1.json
Problem:
I need to be able to remove all link decoration from the download URL that is generated for images in Firebase Storage.
However, when all link decoration is stripped away, the resulting link currently would return a JSON document of the image's metadata.
Context:
The flow goes as follows:
An image is uploaded to Firebase from an iOS app. Once that is done the download URL is then sent in a POST request to an external server.
The server that the URL is being sent to doesn't accept link decoration when submitting image URLs.
Goal:
Alter the Firebase Storage download URL such as it is stripped of all link decoration like so:
https://firebasestorage.googleapis.com/v0/b/example.appspot.com/o/[FOLDER_NAME]%[IMAGE_NAME].jpg
Notes:
The problem is twofold really, first the link needs to be manipulated to remove all the link decoration. Then the behavior of the link needs to changed, since in order to return an image, you need ?alt=media following the file extension, in this case .jpg. Currently, without link decoration, using the link with my desired structure would return a JSON document of the metadata.
The current link structure is as follows:
https://firebasestorage.googleapis.com/v0/b/example.appspot.com/o/[FOLDER_NAME]%[IMAGE_NAME].jpg?alt=media&token=[TOKEN]
Desired link structure:
https://firebasestorage.googleapis.com/v0/b/example.appspot.com/o/[FOLDER_NAME]%[IMAGE_NAME].jpg
The token is necessary for accessing the image depending security rules in place, but can be ignored with the proper read permissions. I can adjust the rules as needed, but I still need to be able to remove the ?alt=media and still return an image.
Building up on Frank's answer, if you access to your associated Google Cloud Platform project, find the bucket in the Storage tab and make this bucket public, you will be able to get the image from here with the format you wish. That is, you will not be accessing through Firebase
https://firebasestorage.googleapis.com/v0/b/example.appspot.com/o/[FOLDER_NAME]%[IMAGE_NAME].jpg
but through Google Cloud Storage, with a link like
https://storage.googleapis.com/[bucket_name]/[path_to_image]
Once in your GCP project Console, access the Storage bucket with the same name as the one you have in your Firebase project. They are the same bucket. Then make the bucket public by following these steps. After that, you will be able to construct your links as mentioned above and they will be accessible with no token and no alt=media param. If you do not want to make the public to everyone, you will be able to play around with the permissions there as you wish.
You could split the url string into two halves by using String.componentsSeparatedByString(_ separator:)
Storage.storage().reference().child(filePath).downloadURL(completion: { (url, error) in
let urlString = url.absoluteString
let urlStringWithoutQueryString = urlString.componentsSeparatedByString("?").first!
})
Calling .downloadURL on a StorageReference will return you that URL, but this method can be used to remove the query string from any URL. String.componentsSeparatedByString(_ separator:) breaks a String into an array of Strings, splitting the string by any occurrence of a given separator, in this case ?.
NOTE this method assumes that ? occurs only once within the url string, which I believe is the case for all Firebase Storage urls.
You should treat the download URL that you get back from Firebase as an opaque string. There's no way to strip the parameters from a download URL without breaking that download URL.
If you want to allow public access to the files in your bucket with simpler URLs, consider making the object in your (or even your entire) bucket public.
Is there a way to construct the client context in AEM by using values passed by an external website? The external website sends the user information such as IP address, page data, geolocation, etc. I want to construct the ClientContext JSON without using CQ_Analytics.ClientContextMgr.init, as the information is from an external system.
For eg: We know the location of a visitor to our website. We want to pass this value to AEM and set the client context so that we can get the targeted content for this location.
Our end goal is to get something like this (but we are trying to achieve this without constructing the JSON by ourselves):
CQ_Analytics.ClientContextMgr.clientcontext = JSON.parse('{"profile":{"country":"US"}}');
Is there any Javascript APIs provided by AEM to construct the JSON?
You need to extend the client context using AEM documentation provided at:
Creating a Custom Context Store Component
Follow the instructions till the Initialization part where you will need to populate the data in the jsp file for your extension.
So in your case it would be something this:
if(!locstore){
locstore = CQ_Analytics.JSONPStore.registerNewInstance("<%= store %>",
"<%= jsonpurl %>",{});
}
Where jsonpurl will be the location of your service that provides the external data in json(p) format. This will initialise your store with the values you want and you won't need to worry about the manual json handcrafting.
Client context is constructed on client side using the JS library in AEM. You will need some binding parameters to connect your external data source to the current client context.
The detailed tutorial can be found here.
I'm using GTM and I need sending several values for each web/product.
In a specific web I've a lightbox to get some data from user and need to send a "conversionValue" with a different value when the user finish the task.
When I try to do this by using dataLayer.push it just add a new object to the original dataLayer (as it is in a fancybox loaded by ajax, not iframe, it gets the "parent page" dataLayer), so I get a dataLayer with many objects and only the last one has the correct "conversionValue".
The problem is, if I try to use this variable from GTM, it gets the first object to look for the conversionValue...
Should I clear the dataLayer before pushing new objects? Am I doing it wrong? Is there any other way to do this?
After reading about Google Tag Manager, it doesn't matter if you add new objects to dataLayer because their variables can't be readed from GTM the same way as you read them for the first time.
You have to read new values by defining events.
I'm trying to use external paging in a JSR-286 portlet with DisplayTag 1.2.
I would like DisplayTag to generate the paging links from a parameterized Action URL that i have defined, but i can't seem to make that work.
Here is the code in my JSP:
<portlet:actionURL var=actionUrl >
<portlet:param name="someParam" value="someValue" >
</portlet:actionURL >
<display-el:table id="personsTable"
name="${portletSessionScope.persons}"
requestURI="${actionUrl}"
partialList="true"
size="${portletSessionScope.total}"
pagesize="${portletSessionScope.pageSize}" >
<display-el:column property="firstName"/ >
</display-el:table >
With the above code, it looks like Display-tag ignores the provided ${actionUrl} and generates a default Render URL. The generated links work fine (i can move through pages), but since my portlet requires an Action request to fetch other pages of data, the list in the session is never updated and the table always contains the same data, regardless of which page i select.
Is there a way i might make that work? Does DisplayTag support what i'm trying to do?
Thanks in advance for your help!
Create a form in your JSP and pass the form name to the displaytag:table as form attribute value. This will invoke the action URL that you have specified.
