A Simple Example

from bsn_sdk import Operator
# user_code, app_code, chain_code, url and cert_path
op = Operator("reddate", "CL1851016378620191011150518", "cc_base", "https://quanzhounode.bsngate.com:17602/api/node/reqChainCode", "./certificate")

# save_data
res = op.save_data("leeduckgo5","test")
# res = {'success': True, 'payload': {'txId': 'c69af29cc00c68456b9e6fe9013f8e4f15ed6e09e3b2250ae3561b9a122ec509', 'context': None}}

# get_data
res = op.get_data("leeduckgo5")
# {'success': True, 'payload': {'txId': '92b61460a31d323d54121c25fced24cacc5102b309f310044ad6b36f42bf05a6', 'context': 'test'}}

# update_data
res = op.update_data("leeduckgo5", "testtest")
# {'success': True, 'payload': {'txId': 'abfe9ee4628efc07086fb81a5b37ef5126898f042868c3d9fade7a7d316ec613', 'context': 'SUCCESS'}}

# delete_data
res = op.delete_data("leeduckgo5")
# {'success': True, 'payload': {'txId': '1b0f298004c9a617ed84dfd4bb989ed03f46e6676668cccfb3bd23117fcd6356', 'context': 'SUCCESS'}}

# get_history
res = op.get_history("leeduckgo5")
{'success': True, 'payload': {'txId': '3ec3174424070b04311af22e0694bba6e099821090cb761a7fae60ce89ef29d4', 'context': [{'txId': 'c69af29cc00c68456b9e6fe9013f8e4f15ed6e09e3b2250ae3561b9a122ec509', 'dataInfo': '{"BaseKey":"leeduckgo5","BaseInfo":"test"}', 'txTime': '2020-01-22 13:18:37', 'isDelete': False}, {'txId': 'abfe9ee4628efc07086fb81a5b37ef5126898f042868c3d9fade7a7d316ec613', 'dataInfo': '{"BaseKey":"leeduckgo5","BaseInfo":"testtest"}', 'txTime': '2020-01-22 13:20:03', 'isDelete': False}, {'txId': '1b0f298004c9a617ed84dfd4bb989ed03f46e6676668cccfb3bd23117fcd6356', 'dataInfo': '', 'txTime': '2020-01-22 13:22:21', 'isDelete': True}]}}
