EOS创建智能合约

1.创建新的公/私钥
xjdeMacBook-Pro:hi xj$ cleos create key --to-console
Private key: 5KLhyM534ZvjJxubEPcZ8pgU9gD8zu4ErxZfhvBVEhsxKv9nbbQ
Public key: EOS7b5YBthLNRuLrk7y2RCHfW1vWB5JGqQVouSMPK7dTpjk4a7veJ

1.5.eosio的私钥也要导入
xjdeMacBook-Pro:cleos xj$ cleos wallet import
private key: imported private key for: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
xjdeMacBook-Pro:cleos xj$ cleos create account eosio xiangj EOS8Loi1SbeLZnqk9fdZTL2rhjGBsEjnR2VdP7PYJeNNeTFvUeU5R
executed transaction: 605984e6dfe3fab0f839771c096d2f5b36003bcb744c45e94c70e54c99bc4e4a  200 bytes  7637 us
#         eosio <= eosio::newaccount            {"creator":"eosio","name":"xiangj","owner":{"threshold":1,"keys":[{"key":"EOS8Loi1SbeLZnqk9fdZTL2rhj...
warning: transaction executed locally, but may not be confirmed by the network yet         ]

2.将上面的私钥导入钱包
xjdeMacBook-Pro:hi xj$ cleos wallet import
private key: imported private key for: EOS6vzUgGinif3gnw75AH436x7P13rQPb75B2R5zn6wQYYeL98X7f

3.根据公钥创建合约帐号
xjdeMacBook-Pro:hi xj$cleos create account eosio xiangj EOS7b5YBthLNRuLrk7y2RCHfW1vWB5JGqQVouSMPK7dTpjk4a7veJ
executed transaction: 85e2e7c038eba8939176bac1ad62b89475e5b6cb565e3bd0cb49106257e76e44  200 bytes  810 us
#         eosio <= eosio::newaccount            {"creator":"eosio","name":"xiangj","owner":{"threshold":1,"keys":[{"key":"EOS7b5YBthLNRuLrk7y2RCHfW1...
warning: transaction executed locally, but may not be confirmed by the network yet         ]

4.编译代码

#include <eosiolib/eosio.hpp>

using namespace eosio;

class hi : public contract {
  public:
      using contract::contract;

      [[eosio::action]]
      void hello( name user ) {
         print( "hello, ", name{user});
      }
};

EOSIO_DISPATCH( hi, (hello))

xjdeMacBook-Pro:helloworld xj$ eosio-cpp -o hi.wasm hi.cpp --abigen
#eos1.8:eosiocpp -o hi.wasm hi.cpp

Warning, empty ricardian clause file
Warning, empty ricardian clause file
Warning, action <hello> does not have a ricardian contract

5.创建合约
xjdeMacBook-Pro:hi xj$ cleos create account eosio hi EOS5ZyWiAYkSo4xhwiAzUhKaSs6coMrQ1nHbpKBprwrQPeZEy9wnU -p eosio@active
executed transaction: 8ecb0c2e061b9f41d3dbe19d784466f2d149d0bc4ba8c507f87308a0aed2048c  200 bytes  854 us
#         eosio <= eosio::newaccount            {"creator":"eosio","name":"hi","owner":{"threshold":1,"keys":[{"key":"EOS5ZyWiAYkSo4xhwiAzUhKaSs6coM...
warning: transaction executed locally, but may not be confirmed by the network yet

6.部署合约
xjdeMacBook-Pro:helloworld xj$cleos set contract hi /Users/xj/code/eos/build/programs/cleos/hi -p hi@active
Reading WASM from /Users/xj/code/eos/build/programs/cleos/hi/hi.wasm...
Publishing contract...
executed transaction: 4317b908267fd4d4b67d6f870f1fba5e825425c3aad8820692386429da316c2d  1440 bytes  1291 us
#         eosio <= eosio::setcode               {"account":"hi","vmtype":0,"vmversion":0,"code":"0061736d0100000001390b60027f7e006000017f60027f7f017...
#         eosio <= eosio::setabi                {"account":"hi","abi":"0e656f73696f3a3a6162692f312e3100010568656c6c6f00010475736572046e616d650100000...
warning: transaction executed locally, but may not be confirmed by the network yet         ]

7.调用合约
xjdeMacBook-Pro:helloworld xj$cleos push action hi hello '["xiangj"]' -p xiangj@active
executed transaction: 2a76833bd8a8373d0b51be07d15e416827b6d48a270e43b1d42a2d908fe31115  104 bytes  509 us
#            hi <= hi::hello                    {"user":"xiangj"}
warning: transaction executed locally, but may not be confirmed by the network yet

8.nodeos控制台查看输出:nodeos --contracts-console
