调用另一个合同的合同

迈克尔逊的一个例子

签订一份合同

 parameter (option string) ;
storage (contract string) ;
code
 {
    UNPAIR ; DIP { DUP } ;
    IF_SOME { } { PUSH string "hello, world" } ;
    PUSH mutez 0 ; SWAP ;
    TRANSFER_TOKENS ;
    NIL operation ; SWAP ; CONS ;
    PAIR
 }
 

和另一个

 parameter string ;
storage string ;
code
  {
    UNPAIR ;
    SWAP ;
    DROP ;
    NIL operation ;
    PAIR  ;
  }
 

第一个合同采用可选的字符串参数,并使用该字符串或未输入的" hello,world"在其存储中调用合同.第二个合同将字符串作为输入并将其放入存储中.

An example in Michelson

Take one contract

parameter (option string) ;
storage (contract string) ;
code
 {
    UNPAIR ; DIP { DUP } ;
    IF_SOME { } { PUSH string "hello, world" } ;
    PUSH mutez 0 ; SWAP ;
    TRANSFER_TOKENS ;
    NIL operation ; SWAP ; CONS ;
    PAIR
 }

and another

parameter string ;
storage string ;
code
  {
    UNPAIR ;
    SWAP ;
    DROP ;
    NIL operation ;
    PAIR  ;
  }

The first contract takes an optional string parameter and calls the contract in its storage with that string, or "hello, world" if none was provided. The second contract takes a string as input and puts it in its storage.
