eosio的mongo插件的使用

eosio提供了mongo插件，实现把数据导到mongo中，从而可以更加灵活的操作数据。

配置（config.ini）

plugin = eosio::mongo_db_plugin
mongodb-uri = mongodb://localhost:27017

本地启动mongo

$ sudo mongod

重启nodeos

$ nodeos --replay-blockchain --hard-replay-blockchain --mongodb-wipe

mongo中查询

$ mongo
> show dbs
EOS     0.372GB
...

> use EOS
switched to db EOS

> show tables
account_controls
accounts
action_traces
block_states
blocks
pub_keys
transaction_traces
transactions

> db.accounts.find().pretty()
{
	"_id" : ObjectId("5bf3cfbf4f6371c75cdc8890"),
	"name" : "superoneiobp",
	"createdAt" : ISODate("2018-11-20T09:11:27.309Z")
}
...
