Information about the co-resident FHIR store
We deploy an instance of the hapi-fhir-jpaserver beside every instance of OpenELIS-GLobal-2 to provide a way to quickly store and query FHIR resources. Usually the communication with the FHIR store is handled through communication by OpenELIS-Global-2, but occaisionally there is a need (debugging, running a reindex, etc) for someone to interact with the FHIR store directly. The FHIR api is well documented online and will not be covered here, but since communication to the FHIR store is locked down to only accept communication over HTTPS with Client Authentication, instructions for communicating via terminal will be covered.
https_proxy
If your server has an https proxy configured, it may interrupt the communication. To alleviate this and communicate directly to localhost, run:
unset https_proxy
Extract certs and keys for use with curl
We will need the key and cert to communicate that OpenELIS-GLobal-2 uses for backend communication. To acomplish this, you will need the password to your keystore. This is located in /var/lib/openelis-global/secrets/common.properties under the server.ssl.key-store-password property.
The key and cert can be retreived from the keystore, but it is important to delete the key after you are done with your comunications, so that a plaintext key isn't left on the server.
Extract cert
sudo openssl pkcs12 -in /etc/openelis-global/keystore -nodes -nokeys -out /etc/openelis-global/cert.pem
Extract key
sudo openssl pkcs12 -in /etc/openelis-global/keystore -nodes -nocerts -out /etc/openelis-global/key.pem
Delete key
sudo rm /etc/openelis-global/key.pem
Communicating with curl
GET Request
sudo curl --cert /etc/openelis-global/cert.pem --key /etc/openelis-global/key.pem -k 'https://localhost:8444/fhir/'
POST Request
sudo curl -X POST -H "Content-Type: application/json" -d '@filename' --cert /etc/openelis-global/cert.pem --key /etc/openelis-global/key.pem -k 'https://192.168.12.157:8444/fhir/'
