使用 Operator.sol 合约的 Solidity 智能合约未调用 Chainlink 作业

Question

在使用Oracle.sol合约的 Solidity 智能合约调用时，部署和运行在 Chainlink 节点上的作业规范被成功触发并完成。

但是，由于要求返回大响应 ( https://docs.chain.link/docs/large-responses/ )，所以我必须使用Operator.sol合同而不是Oracle.sol 。 然后，作业没有被调用。

已部署的 Operator 合约如下所示：

---

我用来部署Operator.sol合约的 LINK 令牌和所有者地址是：

---

LINK 代币地址基本上取自官方 Chainlink 文档 ( https://docs.chain.link/docs/fulfilling-requests/ )，其中提到了 Kovan Tes.net LINK 代币地址：

---

所有者地址取自正在运行的 Chainlink 节点的账户地址：

---

而Solidity智能合约代码为：

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.7;

import "@chainlink/contracts/src/v0.8/ChainlinkClient.sol";

contract GenericLargeResponse is ChainlinkClient {
  using Chainlink for Chainlink.Request;

  bytes public data;

  constructor(
  ) {
    setChainlinkToken(0xa36085F69e2889c224210F603D836748e7dC0088);
    setChainlinkOracle(0x8114f13FaF377FFc7A5AD32fb8a1e448667b871D);
  }

  function requestBytes(
  )
    public
  {
    bytes32 specId = "a3d1b2c945244e44bdb412c5b5287df3";
    uint256 payment = 100000000000000000;
    Chainlink.Request memory req = buildChainlinkRequest(specId, address(this), this.fulfillBytes.selector);
    req.add("data", "{\"agg_x\": \"agg_mean\", \"dataset_code\":\"MODIS/006/MOD14A1\", \"selected_band\":\"MaxFRP\", \"image_scale\":1000, \"start_date\":\"2021-09-01\", \"end_date\":\"2021-09-10\", \"geometry\":{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"properties\":{\"id\":1},\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[29.53125,19.642587534013032],[29.53125,27.059125784374068],[39.90234375,27.059125784374068],[39.90234375,19.642587534013032],[29.53125,19.642587534013032]]]}},{\"type\":\"Feature\",\"properties\":{\"id\":2},\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[46.40625,13.752724664396988],[46.40625,20.138470312451155],[56.25,20.138470312451155],[56.25,13.752724664396988],[46.40625,13.752724664396988]]]}}]}}");
       
    sendOperatorRequest(req, payment);
  }

  function fulfillBytes(
    bytes32 requestId,
    bytes memory bytesData
  )
    public
    recordChainlinkFulfillment(requestId)
  {
    data = bytesData;
  }

}

合约编译部署成功。 但是requestBytes function 无法触发在 Chainlink 节点上运行的作业规范。

PS：使用Oracle.sol的类似智能合约的Oracle.sol成功触发了job-spec。

在 Chainlink 节点上运行的 TOML 作业规范是：

schemaVersion = 1

"""
externalJobID = "a3d1b2c9-4524-4e44-bdb4-12c5b5287df3"

谁能给我指出正确的方向，比如我在这些步骤中做错了什么导致智能合约无法触发工作规范？

Answer 1

首先， Operator.sol的所有者地址应该是进行交易的 Metamask 钱包 Kovan tes.net 地址（而不是正在运行的 Chainlink 节点的帐户地址）。

然后， Operator.sol部署成功后，调用Operator.sol的setAuthorizedSenders function，在 senders address[]字段中传入正在运行的 Chainlink 节点的账户地址，如下所示：

---

然后，作业规范的encode_data也应该有requestId参数：

encode_data  [type="ethabiencode" abi="(bytes32 requestId, uint256[][] value)" data="{ \\"requestId\\": $(decode_log.requestId), \\"value\\": $(parse) }"]

整个工作规范应该是：

type = "directrequest"
schemaVersion = 1
name = "shamba-fire-data"
contractAddress = "0xf4434feDd55D3d6573627F39fA39867b23f4Bf7F"
maxTaskDuration = "0s"
observationSource = """

同样，solidity智能合约代码应该是：

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.7;

import "@chainlink/contracts/src/v0.8/ChainlinkClient.sol";

contract GenericLargeResponse is ChainlinkClient {
  using Chainlink for Chainlink.Request;

  uint256[][] public data;

  constructor(

    setChainlinkToken(0xa36085F69e2889c224210F603D836748e7dC0088);
    setChainlinkOracle(0xf4434feDd55D3d6573627F39fA39867b23f4Bf7F);

  function requestBytes(

    uint256 payment = 1000000000000000000;
    Chainlink.Request memory req = buildChainlinkRequest(specId, address(this), this.fulfillBytes.selector);
    req.add("data", "{\"agg_x\": \"agg_mean\", \"dataset_code\":\"MODIS/006/MOD14A1\", \"selected_band\":\"MaxFRP\", \"image_scale\":1000, \"start_date\":\"2021-09-01\", \"end_date\":\"2021-09-10\", \"geometry\":{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"properties\":{\"id\":1},\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[29.53125,19.642587534013032],[29.53125,27.059125784374068],[39.90234375,27.059125784374068],[39.90234375,19.642587534013032],[29.53125,19.642587534013032]]]}},{\"type\":\"Feature\",\"properties\":{\"id\":2},\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[46.40625,13.752724664396988],[46.40625,20.138470312451155],[56.25,20.138470312451155],[56.25,13.752724664396988],[46.40625,13.752724664396988]]]}}]}}");
       
    sendOperatorRequest(req, payment);
  }

  function fulfillBytes(
    bytes32 requestId,
    uint256[][] memory bytesData
  )
    public
    recordChainlinkFulfillment(requestId)
  {
    data = bytesData;
  }

}
