35.5. 智能合约 - EOS 代币

35.5.1. 编译智能合约

编译 eosio.bios 合约

				
cd /usr/local/src/eos/build/contracts/eosio.bios

[root@netkiller eosio.bios]# make
[  4%] Built target libc++
[  4%] Built target wasm
[  4%] Built target ast
[  4%] Built target asmjs
[  4%] Built target cfg
[ 10%] Built target passes
[ 12%] Built target support
[ 14%] Built target eosio-s2wasm
[ 17%] Built target Platform
[ 17%] Built target Logging
[ 17%] Built target IR
[ 17%] Built target WASM
[ 17%] Built target WAST
[ 17%] Built target eosio-wast2wasm
[ 19%] Built target eosiolib
[100%] Built target libc
[100%] Built target eosio.bios

编译 eosio.token 合约

				
cd /usr/local/src/eos/build/contracts/eosio.token

[root@netkiller eosio.token]# pwd
/usr/local/src/eos/build/contracts/eosio.token
[root@netkiller eosio.token]# make
[  4%] Built target libc++
[  4%] Built target wasm
[  4%] Built target ast
[  4%] Built target asmjs
[  4%] Built target cfg
[ 10%] Built target passes
[ 12%] Built target support
[ 14%] Built target eosio-s2wasm
[ 17%] Built target Platform
[ 17%] Built target Logging
[ 17%] Built target IR
[ 17%] Built target WASM
[ 17%] Built target WAST
[ 17%] Built target eosio-wast2wasm
[ 19%] Built target eosiolib
[100%] Built target libc
[100%] Built target eosio.token

35.5.2. 设置初始化账号 eosio

从配置文件 ~/.local/share/eosio/nodeos/config/config.ini 中查找 signature-provider

				
[root@netkiller ~]# grep "^signature-provider" ~/.local/share/eosio/nodeos/config/config.ini 
signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

找到 signature-provider 配置项，复制秘钥 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3 

				
[root@netkiller ~]# cleos wallet import 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
imported private key for: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

导入 eosio 账号私钥到 default 钱包

				

[root@netkiller ~]# cleos wallet keys
[
  "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV"
]

35.5.3. 创建账号

创建秘钥对

				
[root@netkiller ~]# cleos create key
Private key: 5JFMTVk4EjWW54xk73AMRPf5JbpFV2Cm7vtgt1jr9zVaPgLmaLQ
Public key: EOS7fcRYssRt5SXVnsPpRNzj86E9h5g62hBgKwr1NSzRmSpH9byZr

导入私钥

				
[root@netkiller ~]# cleos wallet import 5JFMTVk4EjWW54xk73AMRPf5JbpFV2Cm7vtgt1jr9zVaPgLmaLQ
imported private key for: EOS7fcRYssRt5SXVnsPpRNzj86E9h5g62hBgKwr1NSzRmSpH9byZr		
	
[root@netkiller ~]# cleos wallet keys
[
  "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
  "EOS7fcRYssRt5SXVnsPpRNzj86E9h5g62hBgKwr1NSzRmSpH9byZr"
]

创建账号 neo

				
[root@netkiller ~]# cleos wallet unlock				
[root@netkiller ~]# cleos create account eosio neo EOS7fcRYssRt5SXVnsPpRNzj86E9h5g62hBgKwr1NSzRmSpH9byZr EOS7fcRYssRt5SXVnsPpRNzj86E9h5g62hBgKwr1NSzRmSpH9byZr

35.5.5. 创建账号 netkiller

创建账号 netkiller 重复上面步骤，这个账号用于创建代币智能合约。

				
[root@netkiller ~]# cleos create key
Private key: 5KVTLTRgLdKj4b5FkkFpYMhYdhimPip3dtdfnZAQVQxQBBV4oFq
Public key: EOS5NyaD49BuTCScNEY8FPBCZ9t6VXThMAmFvgMg72XqcNVPXuEWH

code hash 有值表示合约部署成功

				
[root@netkiller ~]# cleos get code netkiller
code hash: 641f336aa1d08526201599c3c0ddb7a646e5ac8f9fd2493f56414d0422a0f957

code hash 为 0 表示合约部署失败

				
[root@netkiller ~]# cleos get code netkiller
code hash: 0000000000000000000000000000000000000000000000000000000000000000

35.5.7. 创建代币

				
[root@netkiller eosio.token]# cleos wallet unlock
password: Unlocked: default

[root@netkiller eosio.token]# cleos push action netkiller create '["netkiller","1000 EOS",0,0,0]' -p netkiller
executed transaction: 7266dda0b3fde45bd03fc0ab4fdece35e66cf6e616165f113434f63394f3fa33  120 bytes  488 us
#     netkiller <= netkiller::create            {"issuer":"netkiller","maximum_supply":"1000 EOS"}
warning: transaction executed locally, but may not be confirmed by the network yet

[root@netkiller ~]# cleos push action netkiller create '["netkiller","10000 NRC",0,0,0]' -p netkiller
executed transaction: cbb45fcca9e140f24cd90fb6c0fbb781afcc3a1d6da4dc912a7fde79b26b7dd0  120 bytes  521 us
#     netkiller <= netkiller::create            {"issuer":"netkiller","maximum_supply":"10000 NRC"}

{
  "EOS": {
    "supply": "1000 EOS",
    "max_supply": "1000 EOS",
    "issuer": "netkiller"
  }
}

另一个方式

				
cleos push action netkiller create '{"issuer":"netkiller", "maximum_supply": "10.0000 EOS", "can_freeze": 1, "can_recall": 1, "can_whitelist": 1}' -p netkiller@active

35.5.8. 发放代币

				
cleos push action netkiller issue '["neo","1000 EOS","issue"]' -p netkiller

给 neo 账号发放 1000 个 EOS 币

				
[root@netkiller ~]# cleos push action netkiller issue '["neo","1000 EOS","issue"]' -p netkiller
executed transaction: c60760dfbdad2face6917ff28015555f1cfc293d71eb7556fc2f7ec78591229b  128 bytes  1339 us

warning: transaction executed locally, but may not be confirmed by the network yet				
				
			
				
cleos push action netkiller issue '{"to":"neo","quantity":"10.0000 EOS","memo":"备注信息"}' --permission netkiller@active

35.5.9. 查看代币余额

				
[root@netkiller ~]# cleos get table netkiller neo accounts
{
  "rows": [{
      "balance": "1000 EOS"
    }
  ],
  "more": false
}				
				
			

				
[root@netkiller ~]# cleos get currency balance netkiller neo
1000 EOS

[root@netkiller ~]# cleos get currency balance netkiller neo EOS
1000 EOS

35.5.10. 转账

				
cleos push action eosio transfer '["eosio","netkiller","100 EOS",""]' -p eosio		
cleos push action contract transfer '{"from":"from_address","to":"to_address","quantity":"1.0000 EOS","memo":"测试"}' --permission neo@active

操作演示

				
[root@netkiller ~]# cleos get currency balance netkiller netkiller EOS

[root@netkiller ~]# cleos push action netkiller transfer '["neo","netkiller","10 EOS","memo"]' -p neo
executed transaction: 0e23837bd8a3a7876b2463cbde1d47a25d2ac2178bb42ddbccd3037416cc9e43  136 bytes  745 us
#     netkiller <= netkiller::transfer          {"from":"neo","to":"netkiller","quantity":"10 EOS","memo":"memo"}
#           neo <= netkiller::transfer          {"from":"neo","to":"netkiller","quantity":"10 EOS","memo":"memo"}
