How to get all transaction history against a chaincode in Hyperledger fabric

Question

I am able to do transactions in Hyperledger (fabric implementation). I want to see all the transactions and its payload details initiated by a user by passing the user's key.

for example:

A transfers 10 units to B
A transfers 5 units to C
D transfers 8 units to A

When I pass A's key then fabric must provide me all the transactions of A. Is there any way? Or which fabric API function call should I use?

Answer 1

The best and simplest way is to use the shim package function

GetHistoryForKey(key string)

As the documentation says:

GetHistoryForKey function can be invoked by a chaincode to return a history of key values across time. GetHistoryForKey is intended to be used for read-only queries.

Answer 2

/chain/blocks/{Block} endpoint carries ordered list of transactions in a specified block.

Use /chain endpoint to get the height (number of blocks) of your chain, and then retrieve transactions from each block using /chain/blocks/{Block} REST endpoint.

Answer 3

You can develop the proper indexing and query function in your chaincode.

Meaning for each transaction you store its details in the internal key/value store (stub.PutState) with the user as key and return all the transactions associated to a user in your query (stub.GetState).
