use curl to access smart contract

use REST api /hs/send to access smart contract

• /hs/send has three type of MOD

classic transicion

field "data" must be nil( "") field "amount" must be positive( amount >0)

create smart contract

field "data" must not be nil("") field "amount" must be zero( amount == 0)

open smart contract

fields same like create smart contract

caution

when input param change(minter address, from address ,to address , send amount ... ) , must get byte code and fill out the folling "data" field again

create contract

use curl to create
