eos:智能合约

1. 创建钱包

$ cleos wallet create --to-console
Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5JuBXoXJ8JHiCTXf...."

2. 钱包解锁、上锁

$ cleos wallet unlock
password:

cleos wallet lock
Locked: default

3. 导入私钥到钱包

$ cleos wallet import --private-key 5KQw......
imported private key for: EOS6MRy....

4. 创建账号

$ cleos create key --to-console
Private key: 5Jmsawgs...
Public key: EOS7ijWC...

$ cleos wallet import --private-key 5Jmsawgsp1t....
imported private key for: EOS7i...

$ cleos create account eosio user EOS7ijWC.... EOS7i.....

5. 编译合约（EOS笔记四合约工具eosio.cdt使用（转载）：https://www.jianshu.com/p/f2f58eafa595）

a. 安装(https://github.com/EOSIO/eosio.cdt)

    $ wget https://github.com/eosio/eosio.cdt/releases/download/v1.4.1/eosio.cdt-1.4.1.x86_64.deb
    $ sudo apt install ./eosio.cdt-1.4.1.x86_64.deb

b. 编译

// 1 在手动变异wasm文件的同时加上--abigen flag可以同时编译abi文件
$ eosio-cpp hello.cpp -o hello.wasm --abigen

6. 部署合约

$ cleos set contract eosio contracts/eosio.bios -p eosio@active

7. 执行合约

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