如何从其地址调用不同的合约？

Question

在 solidity（以太坊）中，需要合约地址来调用该合约。

contract KittyInterface {
  function getKitty(uint256 _id) external view returns (
    bool isGestating,
    bool isReady,
    uint256 cooldownIndex,
    uint256 nextActionAt,
    uint256 siringWithId,
    uint256 birthTime,
    uint256 matronId,
    uint256 sireId,
    uint256 generation,
    uint256 genes
  );
}

contract ZombieFeeding is ZombieFactory {

  address ckAddress = 0x06012c8cf97BEaD5deAe237070F9587f8E7A266d; 
  KittyInterface kittyContract = KittyInterface(ckAddress);

我可以在 near 协议中这样做吗？ near 中的示例有所不同，需要提供 wasm 文件。 https://github.com/near-examples/rust-high-level-cross-contract

pub fn deploy_status_message(&self, account_id: String, amount: u64) {
        Promise::new(account_id)
            .create_account()
            .transfer(amount as u128)
            .add_full_access_key(env::signer_account_pk())
            .deploy_contract(
                include_bytes!("../status-message-contract/status_message.wasm").to_vec(),
            );
    }

此外，我在使用高级交叉合同代码时遇到错误。 https://gateway.ipfs.io/ipfs/QmPvcjeEE5PJvaJNN2axgKVWGbWVEQCe9q4e95t9NCeGFt/

改为查看锁定合约示例。它使用以下内容：

        ext_whitelist::is_whitelisted(
            staking_pool_account_id.clone(),
            &self.staking_pool_whitelist_account_id,
            NO_DEPOSIT,
            gas::whitelist::IS_WHITELISTED,
        )
        .then(ext_self_owner::on_whitelist_is_whitelisted(
            staking_pool_account_id,
            &env::current_account_id(),
            NO_DEPOSIT,
            gas::owner_callbacks::ON_WHITELIST_IS_WHITELISTED,
        ))

来自 https://github.com/near/core-contracts/blob/cd221798a77d646d5f1200910d45326d11951732/lockup/src/owner.rs#L29-L40

第一次调用接口是(<arg_0>, <arg_1>, ..., <arg_n>, <ACCOUNT_ID>, <ATTACHED_DEPOSIT>, <ATTACHED_GAS>)

<arg_0>, <arg_1>, ..., <arg_n> - 来自下面定义的接口的参数
<ACCOUNT_ID> - 部署调用合约的账户
<ATTACHED_DEPOSIT> - yocto-NEAR 中附加到呼叫的金额
<ATTACHED_GAS> - 传递给调用的 Gas 量

它后来使用 .then 将回调附加到第一个承诺。回调只是另一个异步函数调用。

high-level接口ext_whitelist定义如下：

#[ext_contract(ext_whitelist)]
pub trait ExtStakingPoolWhitelist {
    fn is_whitelisted(&self, staking_pool_account_id: AccountId) -> bool;
}
