The Most Powerful Infrastructure for Decentralized Applications
智能合约发布
- 按照官方文档介绍，首先执行eosd程序,肯定会报错，原因是相关的配置文件必要项没有
- 配置config.ini,该文件在第一步运行一次后，会产生
cd ~/eos/eos/build/programs
vi data-dir/config.ini
需要修改的主要几项是(官方文档提供)：
其中对于创世块的位置，可以默认使用程序自带的,位置在programs目录下，注意大坑！！！！这个genesis.json里面的initial_timestamp千万别改的太临近当前时间，不然无法产生块。。。。
# Load the testnet genesis state, which creates some initial block producers with the default key
genesis-json = ~/eos/eos/build/programs/genesis.json
# Enable production on a stale chain, since a single-node test chain is pretty much always stale
enable-stale-production = true
# Enable block production with the testnet producers
producer-name = inita
producer-name = initb
producer-name = initc
producer-name = initd
producer-name = inite
producer-name = initf
producer-name = initg
producer-name = inith
producer-name = initi
producer-name = initj
producer-name = initk
producer-name = initl
producer-name = initm
producer-name = initn
producer-name = inito
producer-name = initp
producer-name = initq
producer-name = initr
producer-name = inits
producer-name = initt
producer-name = initu
# Load the block producer plugin, so you can produce blocks
plugin = eosio::producer_plugin
# Wallet plugin
plugin = eosio::wallet_api_plugin
# As well as API and HTTP plugins
plugin = eosio::chain_api_plugin
plugin = eosio::http_plugin
现在启动就好了
./eosd/eosd

紧接着下面会有block产生，由于我是第二次启动的所以block没有从第一个开始

- 创建一个钱包
cd ~/eos/eos/build/programs/eosc
./eosc wallet create
这一步会产生钱包的名称以及钱包的密钥

密钥需要保存好，后面需要unlock的时候回用到
- 导入账户
在创世文件中有初始化多个账户，其中一个inita, 它对应的public key 可以看到是
EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
将该账户导入到钱包需要知道的private key，在config.ini中有提供
5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
执行
./eosc wallet import 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
导入成功，现在钱包中有了一个inita的账户，下面还需要再创建一个账户，该账户是我们将创建的合约的拥有者，每个账户需要两个key，所以如下我们创建两个key，并在创建账户的时候，使用上这两个key
> ./eosc create key
Private key: 5Jta_pri1
Public key: EOS8_pub1
> ./eosc create key
Private key: 5JJG_pri2
Public key: EOS5_pub2
# inita 在这里是授权账户，该账户创建了currency账户
./eosc create account inita currency EOS8_pub1 EOS5_pub2
注意上面生成的两个私钥都需要保存
同时把创建的key继续导入的钱包中
./eosc wallet import 5JJG_pri2
现在可以查看这个账户的信息了
./eosc/eosc get account currency
{
"account_name": "currency",
"eos_balance": "0.0000 EOS",
"staked_balance": "0.0001 EOS",
"unstaking_balance": "0.0000 EOS",
"last_unstaking_time": "2106-02-07T06:28:15",
"permissions": [{
"perm_name": "active",
"parent": "owner",
"required_auth": {
"threshold": 1,
"keys": [{
"key": "EOS5n7NbqJb5r6vGVFTB6r5mfBE8fp93xARSxomSHSqTcsvxt1fD9",
"weight": 1
}
],
"accounts": []
}
},{
"perm_name": "owner",
"parent": "",
"required_auth": {
"threshold": 1,
"keys": [{
"key": "EOS8M1GXvH3k6vC5KuVLvm4hUU1AwHozE2nEKTT3yNYFE71V3PVGW",
"weight": 1
}
],
"accounts": []
}
}
]
}
- 合约上传
eos项目默认提供了一个currency合约，我们直接使用该合约上传到eos上，上传之前可以先检验下合约是否存在
./eosc get code currency
code hash: 0000000000000000000000000000000000000000000000000000000000000000
类似的hash值返回表示没有该合约
./eosc set contract currency ../../contracts/currency/currency.wast ../../contracts/currency/currency.abi
这会返回一大串json，就不截图了
我们可以直接查看合约的地址
> ./eosc/eosc get code currency
code hash: 86968a9091ce32255777e2017fccaede8cea2d4978b30f25b41ee97b9d77bed0
- 调用合约
6.1 首先查看两个账户的余额
> ./eosc/eosc get table currency currency account
{
"rows": [{
"key": "account",
"balance": 1000000000
}
],
"more": false
}
> ./eosc/eosc get table inita currency account
{
"rows": [{
"key": "account",
"balance": 0
}
],
"more": false
}
下面调用该合约完成转账,从currency账户转50到inita
./eosc push message currency transfer '{"from":"currency","to":"inita","quantity":50}' --scope currency,inita --permission currency@active
执行完成后，重新查询余额
> ./eosc/eosc get table currency currency account
{
"rows": [{
"key": "account",
"balance": 1000000000
}
],
"more": false
}
> ./eosc/eosc get table inita currency account
{
"rows": [{
"key": "account",
"balance": 0
}
],
"more": false
}
