EOS 智能合约发行货币

今天EOS的WIKI更新了，就试着用mater跑了一下智能合约的流程。

虽然遇到了几个坑，还是跑通了。

下面主要说一些，和318区别的地方

在 ./cloes get account currency的时候

318版本是这样的：

{"account_name": "currency","eos_balance": "0.0000 EOS","staked_balance": "0.0001 EOS","unstaking_balance": "0.0000 EOS","last_unstaking_time": "2035-10-29T06:32:22",
...

master版本，是没有balance几个变量的，不过不影响后续操作，大概下面这个样子：

{"account_name": "currency","last_unstaking_time": "2035-10-29T06:32:22",
...

然后就是发币的环节，要先创造货币，这一步，之前版本是没有的

cleos push action currency create '{"issuer":"currency", "maximum_supply": "1000000000.0000 CUR", "can_freeze": 1, "can_recall": 1, "can_whitelist": 1}' -p currency@active

然后在发行货币

./cleos push action currency issue '{"to":"currency","quantity":"1000.0000 CUR","memo":""}' --permission currency@active

还有一个坑，就是获取账号信息的时候，这里文档写的是这个样子的

./cleos get table currency currency account
{"rows": [{"currency": 1381319428,"balance": 10000000}],"more": false
}

而实际操作是这样子的：

feng@feng-B250-HD3P:~/workSpace/eos/build/programs/cleos$ ./cleos get table currency currency accounts
{"rows": [{"balance": "1000.0000 CUR","frozen": 0,"whitelist": 1}],"more": false
}

区别在哪里呢！？？就是他把account换成了accounts，多了一个s!

下面就是正常操作了，转账显示

feng@feng-B250-HD3P:~/workSpace/eos/build/programs/cleos$ ./cleos push action currency transfer '{"from":"currency","to":"eosio","quantity":"20.0000 CUR","memo":"my first transfer"}' --permission currency@active

}

获取信息的时候要注意eosio的位置。。

feng@feng-B250-HD3P:~/workSpace/eos/build/programs/cleos$ ./cleos get table currency currency accounts
{"rows": [{"balance": "980.0000 CUR","frozen": 0,"whitelist": 1}],"more": false
}

feng@feng-B250-HD3P:~/workSpace/eos/build/programs/cleos$ ./cleos get table currency eosio accounts
{"rows": [{"balance": "20.0000 CUR","frozen": 0,"whitelist": 1}],"more": false
}
