eos智能合约开发-06 token 操作（产出、交易、转账）

创建eos代币

    root@aries-virtual-machine:/home/aries/tmp/eos# cleos push action eosio.token create '[ "eosio", "1000000000.0000 SYS"]' -p eosio.token
    executed transaction: f986e9e6b5c2424af0b7df1d382e21798e4900ee691aeeb1e775334777378de7  120 bytes  2878 us
    #   eosio.token <= eosio.token::create          {"issuer":"eosio","maximum_supply":"1000000000.0000 SYS"}
    warning: transaction executed locally, but may not be confirmed by the network yet    ] 

从返回结果分析： 
    1、这笔交易消耗了120 bytes 1000 cycles. 
    2、eosio.token <= eosio.token::create 说明，这个代币是由eosio.token创建在eosio.token账户上。 
    3、{“issuer”:”eosio”,”maximum_supply”:”1000000000.0000 SYS”}说明，资产发布在eosio账户上，数量”1000000000.0000 SYS”。这一点需要注意，下面调用issue接口的时候，需要用eosio账户签名，因为资产发行在eosio账户上。
