Solidity 智能合约未使用 Operator.sol 合约调用 Chainlink 作业

Question

当使用使用 oracle.sol.sol.sol.sol.sol.sol.sol 合同的固体性智能合约时，已成功触发并完成了在链条节点上部署和运行的作业规格。

但是，由于要求是返回大响应（ https://docs.chain.link /docs/ligal-respons/），所以我必须使用 operator.sol.sol 合同，而不是 oracle.sol.sol.sol.sol 。然后，这项工作没有被称为。

部署的操作员合同看起来为：

---

​

​/I.sstatic.net/e77nz.png“ rel =” nofollow noreferrer“>

---

链接令牌地址基本上取自官方的链条文档（ https：///docs.chain。 link/docs/yearling-requests/）提及kovan testnet链接令牌：

---

，所有者地址是从运行链链接节点的帐户地址获取的：

---

坚固的智能合同代码是：

//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;

  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;
  }

}

合同已成功编译和部署。但是 requestBytes 函数无法触发链条节点上运行的作业规格。

PS：使用 oracle.sol.sol 的类似智能合约的功能成功地触发了作业规格。

在链链接节点上运行的TOML作业规格是：

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

任何人都可以向我指出正确的方向，就像我在这些步骤中做错了什么，智能合约无法触发工作规格？

Answer 1

首先， operator.sol.sol 的所有者地址应为MetAmask Wallet kovan testnet地址（而不是运行链链节点的帐户地址）。

然后，在成功部署 operator.sol.sol 之后，通过传递运行的帐户地址中的帐户地址，调用 setAuthorizedSenders 函数发件人地址[] 字段中的链条节点如：

：//i.sstatic.net/uwgev.png“ alt =” setAuthorizedSenders函数“>

---

然后，Job-Spec的 encode_data 应具有 request> request> reaction> parameter同样：

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

整个工作规格应该是：

同样，坚固的智能合约代码应该是：
