EOS开发(四)通过eosio.token合约在私链发布代币

1.概述

本文主要介绍如何在EOS私链环境创建代币、发行代币、转账，以及对BIOS Contract系统合约的讲解。

2.BIOS合约

此合约可以让我们直接控制其他帐户的资源分配，并使用一些特殊的API。在主链上，此合约管理着用户通过抵押和赎回token，来为其分配CPU，NET和内存资源。

为eosio账号加载bios合约

yuyangdeMacBook-Pro:cleos yuyang$ cleos set contract eosio ../../../build/contracts/eosio.bios -p eosio@active
Reading WASM from ../../../build/contracts/eosio.bios/eosio.bios.wasm...
Publishing contract...
executed transaction: 460436108729af8b8542cb23fa212d8d94ec5f89b2fa2ef1b64dee4b5569101f  3720 bytes  602 us
#         eosio <= eosio::setcode               {"account":"eosio","vmtype":0,"vmversion":0,"code":"0061736d0100000001621260037f7e7f0060057f7e7e7e7e...
#         eosio <= eosio::setabi                {"account":"eosio","abi":"0e656f73696f3a3a6162692f312e30050c6163636f756e745f6e616d65046e616d650f7065...

cleos生成了一个包含两个action的transaction，eosio::setcode和eosio::setabi

代码定义了合同的运行方式，abi描述了如何在参数的二进制和json表示之间进行转换。虽然abi在技术上是可选的，但所有EOSIO工具都依赖于它以便于使用。

这可以理解为：eosio定义的动作setcode，是通过eosio合同带着参数{args...}执行的。

#         ${executor} <= ${contract}:${action} ${args...}
> console output from this execution, if any

我们将会在后面看到，action可以由多个合约处理。

此命令的最后一个参数-p eosio@active，表示通知cleos使用eosio账户的active权限对action进行签名。

3.创建测试用账户

3.1 创建`eosio.token`账户用于部署代币合约

4.部署代币合约

此合约允许创建许多不同的token，这些token全部在同一合约上运行，但可能由不同的用户管理。

使用eosio.token账户部署合约build/contracts/eosio.token：

yuyangdeMacBook-Pro:cleos yuyang$ cleos set contract eosio.token ../../../build/contracts/eosio.token -p eosio.token@active
Reading WASM from ../../../build/contracts/eosio.token/eosio.token.wasm...
Publishing contract...
executed transaction: 9fc1b00c97da6a1893cfcc05b9c25d76b0caed6a4ff10efdc164b812b9c7b2e7  8104 bytes  1023 us
#         eosio <= eosio::setcode               {"account":"eosio.token","vmtype":0,"vmversion":0,"code":"0061736d01000000017e1560037f7e7f0060057f7e...
#         eosio <= eosio::setabi                {"account":"eosio.token","abi":"0e656f73696f3a3a6162692f312e30010c6163636f756e745f6e616d65046e616d65...

5.创建代币

要创建代币，我们必须调用create方法，并使用正确的参数。此命令将注明代币的总量，以及用来与其他代币区分的唯一表示。发行人有发行代币的权限，并可以执行其他操作，例如冻结，召回和将账户加入白名单。

yuyangdeMacBook-Pro:cleos yuyang$ cleos push action eosio.token create '{"issuer":"eosio", "maximum_supply":"1000000000.0000 SYS"}' -p eosio.token@active
executed transaction: b43404b72fc79182617638f49994750886b03dffa87bea72e32b29a120dc845c  120 bytes  1096 us
#   eosio.token <= eosio.token::create          {"issuer":"eosio","maximum_supply":"1000000000.0000 SYS"}
2018-08-29T09:57:22.853 thread-0   main.cpp:455                  print_result   warning: transaction executed locally, but may not be confirmed by the network yet

此命令可以理解为：使用eosio.token账户的active权限，通过eosio.token合约，创建一个新的代币，指定代币发行人为eosio账户。

第一个参数eosio.token表示我们要执行的合约名字。
第二个参数create表示我们要执行的是合约内的具体方法。在eosio.token合约中，create是用于发行token的方法。
第三个参数是一个JSON字符串，其中issuer表示发行人账户，maximum_supply表示token的总量，小数位为4位，标识为SYS。
第四个参数-p依旧是权限指定参数。

6.发行代币

代币已经创建成功，我们发行一些代币给user账户，此部分代币便可以流通了：

yuyangdeMacBook-Pro:cleos yuyang$ cleos push action eosio.token issue '[ "user", "100.0000 SYS", "memo" ]' -p eosio@active
executed transaction: bf06cb3f5df0503cf3ff1766de6ff171fbd37c5c7ec9164dda8b831ce39ab32e  128 bytes  8260 us
#   eosio.token <= eosio.token::issue           {"to":"user","quantity":"100.0000 SYS","memo":"memo"}
#   eosio.token <= eosio.token::transfer        {"from":"eosio","to":"user","quantity":"100.0000 SYS","memo":"memo"}
#         eosio <= eosio.token::transfer        {"from":"eosio","to":"user","quantity":"100.0000 SYS","memo":"memo"}
#          user <= eosio.token::transfer        {"from":"eosio","to":"user","quantity":"100.0000 SYS","memo":"memo"}
2018-08-29T10:17:51.037 thread-0   main.cpp:455                  print_result   warning: transaction executed locally, but may not be confirmed by the network yet

此命令可以理解为：使用eosio账户的active权限，通过eosio.token合约，发行100个SYS给use账户。

输出的内容显示了四个action，一个issue和三个transfer。我们只签署了issue的action，这是一个内联转账。它会通知转账人和收款人账户。

可以使用参数-d -j表示不进行广播，并且将交易信息以json格式返回：

yuyangdeMacBook-Pro:cleos yuyang$ cleos push action eosio.token issue '["user", "100.0000 SYS", "memo"]' -p eosio@active -d -j
{
  "expiration": "2018-08-29T10:34:10",
  "ref_block_num": 15264,
  "ref_block_prefix": 3449560826,
  "max_net_usage_words": 0,
  "max_cpu_usage_ms": 0,
  "delay_sec": 0,
  "context_free_actions": [],
  "actions": [{
      "account": "eosio.token",
      "name": "issue",
      "authorization": [{
          "actor": "eosio",
          "permission": "active"
        }
      ],
      "data": "00000000007015d640420f00000000000453595300000000046d656d6f"
    }
  ],
  "transaction_extensions": [],
  "signatures": [
    "SIG_K1_K8gkaHQ42oqgu3N36F4BBLXbV95TEPeHEyfD9zAWntAkxKgw7ENEZswqJmgVUH8dWSpkArk5Eexg2xdCpYqnz4X4dmTcnK"
  ],
  "context_free_data": []
}

使用cleos get table eosio.token user accounts查看余额

第一个参数表示合约名称
第二个参数表示具体的账户
第三个参数表示合约中的table的名字。eosio.token合约存放账户余额的table名为accounts。

yuyangdeMacBook-Pro:cleos yuyang$ cleos get table eosio.token user accounts
{
  "rows": [{
      "balance": "100.0000 SYS"
    }
  ],
  "more": false
}
yuyangdeMacBook-Pro:cleos yuyang$ cleos get table eosio.token eosio accounts
{
  "rows": [],
  "more": false
}

也可以使用以下方法查询：

yuyangdeMacBook-Pro:cleos yuyang$ cleos get currency balance eosio.token eosio
yuyangdeMacBook-Pro:cleos yuyang$ cleos get currency balance eosio.token user
100.0000 SYS

可以看到user账户有100个SYS，而eosio一个都没有。说明创建代币不等于发行代币，只有发行出来的代币才可进行流通。

7.代币转账

现在使用user的权限，从user往tester进行代币转账：

yuyangdeMacBook-Pro:cleos yuyang$ cleos push action eosio.token transfer '[ "user", "tester", "25.0000 SYS", "m" ]' -p user@active
executed transaction: 5d0504b34569170f3c52d28915bdf94c10d7ad9e591d548fee72000b8a3f2a95  128 bytes  1824 us
#   eosio.token <= eosio.token::transfer        {"from":"user","to":"tester","quantity":"25.0000 SYS","memo":"m"}
#          user <= eosio.token::transfer        {"from":"user","to":"tester","quantity":"25.0000 SYS","memo":"m"}
#        tester <= eosio.token::transfer        {"from":"user","to":"tester","quantity":"25.0000 SYS","memo":"m"}
2018-08-30T01:59:45.077 thread-0   main.cpp:455                  print_result   warning: transaction executed locally, but may not be confirmed by the network yet

查询余额：

yuyangdeMacBook-Pro:cleos yuyang$ cleos get currency balance eosio.token eosio
yuyangdeMacBook-Pro:cleos yuyang$ cleos get currency balance eosio.token user
75.0000 SYS
yuyangdeMacBook-Pro:cleos yuyang$ cleos get currency balance eosio.token tester
25.0000 SYS

助跑小黄瓜:楼主，你好，我们部署了合约，然后一直发行代币发行部了。
cleos --url http://192.30.20.100:4444 push action cceosio issue '["yvonekoge123", "100.0000 CC", "m"]' -p eosio@active

其中cceosio是我们的合约

但是命令一直提醒我：
Error 3120006: No available wallet
Ensure that you have created a wallet and have it open

我在钱包服务里面已经启动过了：

yuyangray:@二分之一小黄瓜你是哪个账号创建的代币呢？也是eosio这个系统账号吗？因为我看你发行代币用的就是eosio
