Verify World State in CouchDB
How to Verify World State in CouchDB container?
✍: FYIcenter.com
Since peer0.org1.example.com uses the couchdb container to
store the world state, you can check the current states
of all assets managed by the chaincode.
1. Get database name for the chaincode "fabcar":
$ curl http://localhost:5984/_all_dbs ["_replicator","_users","mychannel_","mychannel_fabcar","mychannel_lscc"]
2. List all assets (called documents in CouchDB) of "mychannel_fabcar":
$ curl http://localhost:5984/mychannel_fabcar/_all_docs {"total_rows":10,"offset":0,"rows":[ {"id":"CAR0","key":"CAR0","value":{"rev":"2-470e6972dfda1d4e4d5451f351e0a148"}}, {"id":"CAR1","key":"CAR1","value":{"rev":"2-c3dc6200995111fd68a1b31fef101407"}}, {"id":"CAR2","key":"CAR2","value":{"rev":"2-a6152f6417c7806ca9b8cb65df610408"}}, {"id":"CAR3","key":"CAR3","value":{"rev":"2-2284005a15045726607cd868bded26e7"}}, {"id":"CAR4","key":"CAR4","value":{"rev":"2-a76d55af36a1c1d876db82bac10a5193"}}, {"id":"CAR5","key":"CAR5","value":{"rev":"2-34515cfea948a09c67f5fee6fd286ff6"}}, {"id":"CAR6","key":"CAR6","value":{"rev":"2-d52f643d550d6b6b1126c60fa71386c3"}}, {"id":"CAR7","key":"CAR7","value":{"rev":"2-bf0c75774546d03bba5e3ada27be3afe"}}, {"id":"CAR8","key":"CAR8","value":{"rev":"2-a953576d2447d0bc4c6534a0cfc1aeca"}}, {"id":"CAR9","key":"CAR9","value":{"rev":"2-06ab42f3f3274b05144522b717c04e56"}} ]}
3. Get the content of the last asset, CAR9:
$ curl http://localhost:5984/mychannel_fabcar/CAR9 { "_id": "CAR9", "_rev": "2-06ab42f3f3274b05144522b717c04e56", "colour": "brown", "make": "Holden", "model": "Barina", "owner": "Shotaro", "~version": "\u0000CgMBAwA=" }
