In this Cordapp, you will be able to create a token and attached a few message strings. You can later retrieve the token and the strings via query.
We have built a front end interface to make the interaction easier. Clone the app and give a try!
Set up for CorDapp development
./gradlew clean build deployNodes
./build/nodes/runnodes
Go to the operator node:
flow start CreateMyToken myEmail: [email protected], recipients: [email protected], msg: Corda Number 1!
then record the returned uuid
flow start IssueToken uuid: xxx-xxxx-xxxx-xxxx-xx
record the message returned, TokenId and storage node.
Go to that storage node terminal:
flow start QueryToken uuid: xxx-xxxx-xxxx-xxxx-xx, recipientEmail: [email protected]
You should discover the message that was attached in the token.
Open a new window and run the blow code for token issuance
./gradlew runOperatoreServer
To retrieve the token, because most people will run the app locally, by default I have the gradle task to start only one storage node's web server.
./gradlew runUSWest1Server
After both servers started, go to localhost:10050 to issue a token and localhost:10053 to experience the retrieve. (The reason it is two different site is that communicating among multiple local server is prohibited by CORS policy. In production environment, we do not need to go to a different site for retrieve.)
