运行本地节点

方法1

nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::chain_api_plugin --plugin eosio::account_history_api_plugin

方法2

step1:运行nodeos，节点会创建nodeos的config.ini 文件，文件地址可能在两个地方： 1.eos/build/etc/node_00/ 2.~/.local/share/eosio/nodeos/config/
step2: 更改config文件，然后运行nodeos，就可以正常运行。

创建钱包

创建钱包的操作跟2.0一样，这里就不再多说基本的步骤：

cleos wallet create -n wallet_name //创建钱包
cleos wallet import -n wallet_name key //导入私匙
cleos wallet open -n wallet_name //
cleos wallet unlock -n wallet_name --password password
cleso wallet lock_all
cleos wallet lock -n wallet_name

使用系统默认的eosio.bios合约

现在我们有一个带有eosio加载密钥的钱包，我们可以设置默认的系统合同。为了开发目的，可以使用默认的eosio.bios合约。此合约使您可以直接控制其他帐户的resoruce分配并访问其他特权api调用。在公共区块链中，该合同将管理令牌的放样和取消操作，以预留cpu和网络活动的带宽以及合同的内存。

执行结果如下：

lome@lome:~/eos/build$ cleos set contract eosio contracts/eosio.bios -p eosio

创建账户

创建账户的代码跟2.0也是一样的：

lome@lome:~/eos/build$ cleos create account eosio lome EOS5sU4bj1UhjNNLzP4CYmmoHPm9rpUkqX74ra5FiFwBGwznHt59P EOS5sU4bj1UhjNNLzP4CYmmoHPm9rpUkqX74ra5FiFwBGwznHt59P

通过key获取账户

1.在创建一个账户：

lome@lome:~/eos/build$ cleos create account eosio lome2 EOS5sU4bj1UhjNNLzP4CYmmoHPm9rpUkqX74ra5FiFwBGwznHt59P EOS5sU4bj1UhjNNLzP4CYmmoHPm9rpUkqX74ra5FiFwBGwznHt59P

#         eosio <= eosio::newaccount            {"creator":"eosio","name":"lome2","owner":{"threshold":1,"keys":[{"key":"EOS5sU4bj1UhjNNLzP4CYmmoHPm...

获取使用该密匙的账户：

lome@lome:~/eos/build$ cleos get accounts EOS5sU4bj1UhjNNLzP4CYmmoHPm9rpUkqX74ra5FiFwBGwznHt59P
{
  "account_names": [
    "lome",
    "lome2"
  ]
}

创建一个token 合约

创建账户

lome@lome:~/eos/build$ cleos create account eosio eosio.token EOS8mvgDwRv8kiX213BN38UeTE8ga2TckKyKUaAGzE3LguCKVETzu EOS8mvgDwRv8kiX213BN38UeTE8ga2TckKyKUaAGzE3LguCKVETzu

创建EOS token

我们可以在eosio.token合约中看到,合约有三个方法如下所示:

void create(
  account_name issuer,
  asset        maximum_supply,
  uint8_t      issuer_can_freeze,
  uint8_t      issuer_can_recall,  
  uint8_t      issuer_can_whitelist
);
void issue( account_name to, asset quantity, string memo );
void transfer(
  account_name from,
  account_name to,
  asset quantity,
  string memo
);

一个创建\一个发布\一个转账.

创建EOS token

lome@lome:~/eos/build$ cleos push action eosio.token create '["eosio","10000000000.0000 EOS",0,0,0]' -p eosio.token
executed transaction: a160153e605f047e67a02a330a564cdd1a5cdb53c0b4245a65c0145e80e0c19e  260 bytes  1000 cycles
#   eosio.token <= eosio.token::create          {"issuer":"eosio","maximum_supply":"10000000000.0000 EOS","can_freeze":0,"can_recall":0,"can_whiteli...

另外一种更详细的方式来调用这个方法，使用命名参数：

lome@lome:~/eos/build$ cleos push action eosio.token create '{"issuer":"eosio","maximum_supply":"10000000000.0000 EOS","can_freeze":0,"can_recall":0,"can_whitelist":0}' -p eosio.token
executed transaction: a160153e605f047e67a02a330a564cdd1a5cdb53c0b4245a65c0145e80e0c88e  260 bytes  1000 cycles
#   eosio.token <= eosio.token::create          {"issuer":"eosio","maximum_supply":"10000000000.0000 EOS","can_freeze":0,"can_recall":0,"can_whiteli...

发放token

lome@lome:~/eos/build$ cleos push action eosio.token issue '[ "lome", "100.0000 EOS", "memo" ]' -p eosio
executed transaction: fff713e1bebdd34b91e08de07e4df8e3060356ca79d902226b83f2fe9198d507  268 bytes  1000 cycles
#   eosio.token <= eosio.token::issue           {"to":"lome","quantity":"100.0000 EOS","memo":"memo"}
>> issue
#   eosio.token <= eosio.token::transfer        {"from":"eosio","to":"lome","quantity":"100.0000 EOS","memo":"memo"}
>> transfer
#         eosio <= eosio.token::transfer        {"from":"eosio","to":"lome","quantity":"100.0000 EOS","memo":"memo"}
#          lome <= eosio.token::transfer        {"from":"eosio","to":"lome","quantity":"100.0000 EOS","memo":"memo"}

从显示的日志可以看到具体的转账信息.

如果你想看到详情可以使用-d -j命令,他会以json的形式返回传账信息.

lome@lome:~/eos/build$ cleos push action eosio.token issue '[ "lome", "100.0000 EOS", "memo" ]' -p eosio -d -j

  "expiration": "2018-04-02T09:13:18",

        }
      ],
      "data": "0000000000a0248d40420f000000000004454f5300000000046d656d6f"

  ],
  "context_free_data": []
}

转账给用户

将账户余额转给其它用户:

lome@lome:~/eos/build$ cleos push action eosio.token transfer '[ "lome", "lome2", "25.0000 EOS", "m" ]' -p lome
executed transaction: b1295caa79423f35e6710bbffc5221ab0980b959aeff052592cb1c491b09e28a  268 bytes  1000 cycles
#   eosio.token <= eosio.token::transfer        {"from":"lome","to":"lome2","quantity":"25.0000 EOS","memo":"m"}
>> transfer
#          lome <= eosio.token::transfer        {"from":"lome","to":"lome2","quantity":"25.0000 EOS","memo":"m"}
#         lome2 <= eosio.token::transfer        {"from":"lome","to":"lome2","quantity":"25.0000 EOS","memo":"m"}
