Using GraphQL Queries in OSGi Services

[naan_raja]

We have complex and nested content model and corresponding fragments. We would like to use GraphQL to fetch the content from the content fragment and display in the website. 

Using OSGi Service or Sling Model, how can we execute a GraphQL query?

@naan_raja , Graph QL is used by application outside AEM to consume the content fragments thru Graph QL API by end points. AEM internally converts the Graph QL API call to SQL query and executes the query and sends the result. 

If you want to consume content fragments inside the AEM, i would think about using OSGI Service running querybuilder API or sling model to read the CFs. 

If you still want to consume the Graph QL API, you can make the java POST call to end points from services.

@naan_raja  Try Post call using HTTP client with graphql query as stringEntity in your OSGI service and get the desired response.
