EOS3.0 智能合约使用指南。

EOSIO 3.0 使用指南
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：
eos/build/etc/node_00/~/.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

# eosio <= eosio::newaccount{"creator":"eosio","name":"lome","owner":{"threshold":1,"keys":[{"key":"EOS5sU4bj1UhjNNLzP4CYmmoHPm9...
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
executed transaction: deab457f2c4f4e98f7447fd87ccb92149766f809dcd3577525e03c87fa4d55c5364 bytes1000 cycles
# eosio <= eosio::newaccount{"creator":"eosio","name":"lome2","owner":{"threshold":1,"keys":[{"key":"EOS5sU4bj1UhjNNLzP4CYmmoHPm...
2. 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
1. 创建账户
lome@lome:~/eos/build$ cleos create account eosio eosio.token EOS8mvgDwRv8kiX213BN38UeTE8ga2TckKyKUaAGzE3LguCKVETzu EOS8mvgDwRv8kiX213BN38UeTE8ga2TckKyKUaAGzE3LguCKVETzu

# eosio <= eosio::newaccount{"creator":"eosio","name":"eosio.token","owner":{"threshold":1,"keys":[{"key":"EOS8mvgDwRv8kiX213BN3...
2. 部署合约
lome@lome:~/eos/build$ cleos set contract eosio.token contracts/eosio.token -p eosio.token
