自动生成 abi 文件函数：添加注释 //@abi action ，最新版本可以不写需要EOSIO_ABI中添加对应函数（必须）。

结构体：需要 //@abi table name type（必须）

1.1 int类型相关说明

生成 abi 可以支持的 int 类型

uint64_t uint32_t uint16_t uint8_t

int64_t int32_t int16_t int8_t

eosio::print 输出只支持以下 int 类型

uint64_t uint32_t int64_t int32_t

1.2 函数书写和合约调用

下面介绍一下，合约中支持哪些类型和怎么传参数的。

1.2.1 account_name 类型

继承类自己定义的，还有其他类型，这里不一一列举了

函数，这里eosio::name 暂时用不了了，可能是最近改动过了，但是我没找到相关log

// @abi action 
void hi(account_name user ) { 
require_auth( user );
eosio::print( "hi, ", user); 
//eosio::print( "hi, ", eosio::name(user)); 
}

合约调用

cleos push action user hi '[user]' -p user 
executed transaction: 9b904829cb37416b283148c0579e8081403feca2306a39ab40470f163bfd0d08 232 bytes 102400 cycles
# user <= user::hi {"user":"user"}
>> hi, 15426359243929812992

1.2.2 std::string 类型

// @abi action
void abiprint(std::string str) {
eosio::print("abiprint, ",str.c_str() );
}

合约调用

cleos push action user abiprint '["OuterTS"]' -p user
executed transaction: f6cf3d91c4aba8c71b096557615fcfce24a000a361503abc27d0201b6646f28d 232 bytes 102400 cycles
# user <= user::abiprint {"str":"OuterTS"}
>> abiprint, OuterTS

1.2.3 int相关类型

这里声明一下，带有返回参数的，不能生成abi文件

// @abi action
void abiadd (uint64_t num1, uint64_t num2) {
eosio::print( "add:, ", add(num1 , num2) ); 
}

uint64_t add (uint64_t num1, uint64_t num2){
return num1 + num2; 
} 

void mulnum( uint64_t num1,uint32_t num2,uint16_t num3,uint8_t num4,
int64_t num5,int32_t num6,int16_t num7,int8_t num8) {
eosio::print("eosio::print dont support others");
eosio::print("num1:",num1," num2:",num2,"\n");
eosio::print("num5:",num5," num6:","\n");

}

合约调用

cleos push action user abiadd '[9527,9527]' -p user
executed transaction: 65e9c964929bcc4851fba6dbcbf5bdfef57dc55170b19a091c9c9699a14cce47 240 bytes 102400 cycles
# user <= user::abiadd {"num1":9527,"num2":9527}
>> add:, 19054



cleos push action user mulnum '[9527,9527,9527,9527,9527,9527,9527,9527]' -p user
executed transaction: d068edbd729346e8e58038997c850875de7ec13517de7a301e4336217b9b0b2d 256 bytes 102400 cycles
# user <= user::mulnum {"num1":9527,"num2":9527,"num3":9527,"num4":55,"num5":9527,"num6":9527,"num7":9527,"num8":55}
>> eosio::print dont support othersnum1:9527 num2:9527

1.2.4 vector类型和多种类型传参

// @abi action
void mulargs(int64_t num, std::string str,std::vector<uint64_t> iarr) {
eosio::print("num:",num,"\n");
eosio::print("str:",str.c_str(),"\n");
for (int i = 0; i < iarr.size(); ++i)
{
eosio::print(iarr[i]);
}

}

合约调用

cleos push action user mulargs '[9527,"OuterST",[9,5,2,7]]' -p user
executed transaction: a84344447e58bbe3fe6b27a7cebe750bde802ed8d57904db2965e03c1c0840de 272 bytes 104448 cycles
# user <= user::mulargs {"num":9527,"str":"OuterST","iarr":[9,5,2,7]}
>> num:9527

2. cpp源码和abi文件

2.1 生成abi文件

feng@feng-B250-HD3P:~/work/eos/build/contracts/hellocopy$ eosiocpp -g hellocopy.abi hellocopy.cpp

2.2 生成wast文件

feng@feng-B250-HD3P:~/work/eos/build/contracts/hellocopy$ eosiocpp -o hellocopy.wast hellocopy.cpp

2.3 部署合约

合约更新的时候，需要重新生成abi文件和wast文件。

每次部署合约需要保证code的变化：所以部署A合约的时候，再一次部署A合约会失败。

要想更新A合约，需要先部署B合约，再一次部署A合约。

feng@feng-B250-HD3P:~/work/eos/build$ cleos set contract user contracts/hellocopy/

2.4 cpp文件
