添加生产账号

在config.ini中配置了多个producer

private-key = ["EOS67C9QroNTsJg4bWFoQqXkzVaWsysDb5cqgz8vcnBX2QhSwoETs","5KG314q9BWCdb9yoXK2vioCaf6cmYBoC27kmooNCNsMHe22kgVV"]
producer-name = eosio
producer-name = morea
producer-name = moreb
producer-name = morec

创建这些账号

$ cleos create account eosio morea EOS67C9QroNTsJg4bWFoQqXkzVaWsysDb5cqgz8vcnBX2QhSwoETs EOS67C9QroNTsJg4bWFoQqXkzVaWsysDb5cqgz8vcnBX2QhSwoETs

部署Token合约

创建合约用户

$ cleos create key
Private key: 5J8tcyswr57zZtmui9REGc1MRMGS16DtCQ9TRnzjDAcLNiQ4vvg
Public key: EOS6M8Tdn1BNVuqt9CJU7MoW28K1XhRBDvBsFQhF6LPfeYgVrWPYi
$ cleos create account eosio eosio.token EOS6M8Tdn1BNVuqt9CJU7MoW28K1XhRBDvBsFQhF6LPfeYgVrWPYi EOS6M8Tdn1BNVuqt9CJU7MoW28K1XhRBDvBsFQhF6LPfeYgVrWPYi
$ cleos wallet import 5J8tcyswr57zZtmui9REGc1MRMGS16DtCQ9TRnzjDAcLNiQ4vvg

导入合约

$ cleos set contract eosio.token contracts/eosio.token -p eosio.token

发布Token

首先需要运行create action

$ cleos push action eosio.token create '{"issuer":"eosio", "maximum_supply":"1000000000.0000 EOS", "can_freeze":0, "can_recall":0, "can_whitelist":0}' -p eosio.token

然后发行token

$ cleos push action eosio.token issue '["eosio","1000000000.0000 EOS","deposit started"]' -p eosio

获取余额

$ cleos get currency balance eosio.token eosio
1000000000.0000 EOS

转账

首先创建一个测试用户

$ cleos create key
Private key: 5Jcc9Fm6ZPBUs8iYWR5eMUHWCeF19GmAKMAiRQHFpmCJvDjkbfR
Public key: EOS6xP5M1QaUbDqHq9SVm711ApidsYeLjUYSTFvMdwtoen8Mzt4co
$ cleos create account eosio tester EOS6xP5M1QaUbDqHq9SVm711ApidsYeLjUYSTFvMdwtoen8Mzt4co EOS6xP5M1QaUbDqHq9SVm711ApidsYeLjUYSTFvMdwtoen8Mzt4co

向其转账100 EOS

$ cleos push action eosio.token transfer '{"from":"eosio","to":"tester","quantity":"100.0000 EOS","memo":"transfer to"}' -p eosio

查看余额

$ cleos get currency balance eosio.token eosio
999999900.0000 EOS
$ cleos get currency balance eosio.token tester
100.0000 EOS

第一个智能合约

Hello World

contracts中新建文件夹hello，编写文件hello.cpp

#include <eosiolib/eosio.hpp>
#include <eosiolib/print.hpp>
using namespace eosio;

class hello : public eosio::contract {
    public:
        using contract::contract;
        void hi(account_name user) {
            require_auth( user );
            print("Hello, I'm ", name{user});
        }
};

EOSIO_ABI(hello, (hi))

生成wast和abi文件

$ eosiocpp -o contracts/hello/hello.wast contracts/hello/hello.cpp
$ eosiocpp -g contracts/hello/hello.abi contracts/hello/hello.cpp

创建合约账号并部署

$ cleos create key
Private key: 5J5eiQtGkMZHeJjrpLemQies93rzNVfhnR8wQCQc6WDjkqSMH3k
Public key: EOS6ghTFAieviETGYmPeefvSwYBPAgMgLsgSfHG2i8etUJk41Cbhu
$ cleos create account eosio hello EOS6ghTFAieviETGYmPeefvSwYBPAgMgLsgSfHG2i8etUJk41Cbhu EOS6ghTFAieviETGYmPeefvSwYBPAgMgLsgSfHG2i8etUJk41Cbhu
$ cleos wallet import 5J5eiQtGkMZHeJjrpLemQies93rzNVfhnR8wQCQc6WDjkqSMH3k
$ cleos set contract hello contracts/hello -p hello

运行Action

$ cleos push action hello hi '{"user":"eosio"}' -p eosio
executed transaction: 0ec6e00144140f50e55e77750949a501d4fedd945e35668b72fe5e77242ea35e  232 bytes  102400 cycles
#         hello <= hello::hi                    {"user":"eosio"}
>> Hello, I'm eosio

合约进阶

新建一个包含数据表的合约

#include <eosiolib/eosio.hpp>
#include <eosiolib/print.hpp>

using namespace eosio;
using namespace std;

class basics : public contract {
    using contract::contract;

public:
    basics( account_name self ) :
            contract(self),
            _statuses(_self, _self){}

    // @abi action
    void test( name sender, string status ){
        require_auth(sender);

        auto iter = _statuses.find(sender);
        if(iter == _statuses.end()) _statuses.emplace( sender, [&]( auto& row) {
                row.sender = sender;
                row.status = status;
            });
        else _statuses.modify( iter, 0, [&]( auto& row) {
                row.status = status;
            });
    }

private:

    // @abi table
    struct statuses {
        name sender;
        string status;

        name primary_key() const { return sender; }
        EOSLIB_SERIALIZE( statuses, (sender)(status) )
    };

    multi_index<N(statuses), statuses> _statuses;


};

EOSIO_ABI( basics, (test) )

部署合约

$ cleos set contract basics contracts/basics -p basics

数据表变化

运行一次test Action

$ cleos push action basics test '{"sender":"eosio","status":"resting"}' -p eosio

查看table

$ cleos get table basics basics statuses
{
  "rows": [{
      "sender": "eosio",
      "status": "resting"
    }
  ],
  "more": false
}
