账户

cleos create key -f myKey.txt

cleos create account [OPTIONS] creator name OwnerKey ActiveKey

If the system contract is loaded, (for example a production network) then use cleos system newaccountinstead

cleos create account eosio bob EOS72iMnMyaADjELbrAe3f9fUmKe6aEUqr6Hypa3wpVpAry1b3wHQ EOS8Yxz5xQnELbg4yosR5CLeUA3kdF4fiM4CEX2fFyHL4yZ2gQBCj

cleos create account eosio bob123 EOS6erobkNLjYFzUbfr2P778kHrRo5P7d5b5tMMShVgoQ92P7g2Mo

cleos create account eosio alice EOS6erobkNLjYFzUbfr2P778kHrRo5P7d5b5tMMShVgoQ92P7g2Mo

合约

编译

eosio-cpp -o hello.wasm hello.cpp --abigen

创建自己的合约账户

cleos create account eosio hello EOS6erobkNLjYFzUbfr2P778kHrRo5P7d5b5tMMShVgoQ92P7g2Mo -p eosio@active

部署代币合约

cleos set contract hello /root/contract/hello -p hello@active

调用合约方法

cleos push action hello hi '["bob"]' -p alice@active

权限验证

Use the require_auth method. This method takes an name as a parameter, and will check if the user executing the action matches the provided paramter.

cleos push action hello hi '["alice123"]' -p alice@active

Error 3090004: Missing required authority

Ensure that you have the related authority inside your transaction!;

If you are currently using 'cleos push action' command, try to add the relevant authority using -p option.

使用 eos 已有代码部署合约

开发者公钥，合约 eosio.token

cleos create account eosio eosio.token EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

编译

eosio-cpp -I include -o eosio.token.wasm src/eosio.token.cpp --abigen

部署

cleos set contract eosio.token /root/contract/eosio.contracts/eosio.token --abi eosio.token.abi -p eosio.token@active

发币

发行新代币 SYS，1000000000.0000 个
Create the Token 创建新 token

cleos push action eosio.token create '[ "eosio", "1000000000.0000 SYS"]' -p eosio.token@active

发行向 Alice issue 100 SYS

cleos push action eosio.token issue '[ "alice", "100.0000 SYS", "memo" ]' -p eosio@active

开发调试选项

To inspect the transaction, try using the -d -j options, they indicate "don't broadcast" and "return transaction as json," which you may find useful during development.

cleos push action eosio.token issue '["alice", "100.0000 SYS", "memo"]' -p eosio@active -d -j
