为什么近距离找不到我的合同方法？

Question

所以我已经为我的合同实现了这个功能

#[payable]
fn send_message(mut self, message: &str, receiver: &str) {

当我试图用接近cli来称呼它时

near call v1.messenger.ijelis.testnet send_message '{"message": "test","sender": "iejlis.near"}' --account-id ijelis.testnet

它给了我这个

Scheduling a call: v1.messenger.ijelis.testnet.send_message({"message": "test","sender": "iejlis.near"})
Doing account.functionCall()
Receipt: DDXubobUugwsGnr9GqXxMv7PJqT3YsLjTn14xWML4vx
    Failure [v1.messenger.ijelis.testnet]: Error: Contract method is not found

  transaction_outcome: {
    proof: [ [Object] ],
    block_hash: 'G4QJ5PPykJWieCyi9P5Rzxu73t1YCKLGKnWL7Z5nUbhd',
    id: 'ExJyHwyCpjrFBXGXyr35Y6itkTPVpN1MtE4RnDbo2HBz',
    outcome: {
      logs: [],

      gas_burnt: 2428039504502,
      tokens_burnt: '242803950450200000000',
      executor_id: 'ijelis.testnet',
      status: [Object],
      metadata: [Object]
    }
  }
}

我做错什么了？

编辑:我试着使用接近创建应用程序的界面来部署它，一切都很好。

Answer 1

看来你没有把合同部署到这个账户上。

像这样检查：

1.有什么东西部署到帐户上了吗？

使用接近CLI快速查看帐户状态(https://docs.near.org/docs/tools/near-cli#near-state)

near state v1.messenger.ijelis.testnet send_message

结果

{
  amount: '2099882635532834400000000',
  locked: '0',
  code_hash: 'E8jZ1giWcVrps8PcV75ATauu6gFRkcwjNtKp7NKmipZG',
  storage_usage: 268,
  storage_paid_at: 0,
  block_height: 74201501,
  block_hash: '46fdR4oFfEDDuNmLMM8Le6FbKPR3VG5zzNni7u9uE3XQ',
  formattedAmount: '2.0998826355328344'
}

结论

是的，帐户部署了一些东西，因为code_hash的值不是默认的11111111111111111111111111111111，而是E8jZ1giWcVrps8PcV75ATauu6gFRkcwjNtKp7NKmipZG，它是合同字节代码的base58编码的sha256摘要，是部署到帐户上可用的“合同槽”的数据的指纹。

2.究竟在账户中部署了什么？

使用API查看合同代码：https://docs.near.org/docs/api/rpc/contracts#view-contract-code

http post https://rpc.testnet.near.org jsonrpc=2.0 id=dontcare method=query \
  params:='{
    "request_type": "view_code",
    "finality": "final",
    "account_id": "v1.messenger.ijelis.testnet"
  }'

结果

{
    "id": "dontcare",
    "jsonrpc": "2.0",
    "result": {
        "block_hash": "48uCNbhhB9FSg35bJgMDvTpjS5f9n4jrnU4MmMmbHsqj",
        "block_height": 74201992,
        "code_base64": "AGFzbQEAAAAEBQFwAQEBBQMBABAGGQN/AUGAgMAAC38AQYCAwAALfwBBgIDAAAsHJQMGbWVtb3J5AgAKX19kYXRhX2VuZAMBC19faGVhcF9iYXNlAwI=",
        "hash": "E8jZ1giWcVrps8PcV75ATauu6gFRkcwjNtKp7NKmipZG"
    }
}

结论

AGFzbQEAAAAEBQFwAQEBBQMBABAGGQN/AUGAgMAAC38AQYCAwAALfwBBgIDAAAsHJQMGbWVtb3J5AgAKX19kYXRhX2VuZAMBC19faGVhcF9iYXNlAwI=看起来太小了，不适合作为合同，尤其是用锈蚀写成的合同(它们通常比AssemblyScript合同稍大一点)

此base64编码的字符串解码为以下水

(module
  (table $T0 1 1 funcref)
  (memory $memory (export "memory") 16)
  (global $g0 (mut i32) (i32.const 1048576))
  (global $__data_end (export "__data_end") i32 (i32.const 1048576))
  (global $__heap_base (export "__heap_base") i32 (i32.const 1048576)))

所以你认为的合同实际上是没有的。

解决方案

将合同部署到帐户v1.messenger.ijelis.testnet

注:上述WAT分两个步骤生成：

(1)。echo "AGFzbQEAAAAEBQFwAQEBBQMBABAGGQN/AUGAgMAAC38AQYCAwAALfwBBgIDAAAsHJQMGbWVtb3J5AgAKX19kYXRhX2VuZAMBC19faGVhcF9iYXNlAwI=" | base64 -d > contract.wasm

(2)。将Wasm文件上载到https://webassembly.github.io/wabt/demo/wasm2wat/
