This Chainlink has a dedicated connection to FlightAware.

Steps for using this oracle

• Write and deploy your Chainlink contract using the network details below
• Fund it with LINK
• Call your request method

Chainlink Network Details

You will need to use the following LINK token address, oracle address, and Job IDs to create the request.

Create your Chainlink contract

Import ChainlinkClient.sol into your contract so you can inherit the Chainlink behavior.

pragma solidity ^0.6.0;
import "@chainlink/contracts/src/v0.6/ChainlinkClient.sol";
contract FlightAwareChainlink is ChainlinkClient {

  uint256 oraclePayment;

  constructor(uint256 _oraclePayment) public {
    setPublicChainlinkToken();
    oraclePayment = _oraclePayment;
  }
  // Additional functions here:

}

pragma solidity ^0.5.0;
import "@chainlink/contracts/src/v0.5/ChainlinkClient.sol";
contract FlightAwareChainlink is ChainlinkClient {

  uint256 oraclePayment;

  constructor(uint256 _oraclePayment) public {
    setPublicChainlinkToken();
    oraclePayment = _oraclePayment;
  }
  // Additional functions here:

}

pragma solidity ^0.4.24;
import "@chainlink/contracts/src/v0.4/ChainlinkClient.sol";
contract FlightAwareChainlink is ChainlinkClient {

  uint256 oraclePayment;

  constructor(uint256 _oraclePayment) public {
    setPublicChainlinkToken();
    oraclePayment = _oraclePayment;
  }
  // Additional functions here:

}

Request Parameters

endpoint

The endpoint to query (optional, defaults to FlightInfoEx)

Solidity example

req.add("endpoint", "FlightInfoEx");

flight

The flight identification/number (required)

Solidity example

req.add("flight", "NAX105");

departure

The unix timestamp of the departure (required)

Solidity example

req.addUint("departure", 1594378824);

until

Required for the Sleep job

Solidity example

req.addUint("until", now + 1 hours);

Chainlink Examples

The examples below use the different endpoints available from this Chainlink:

function createRequest
(
  address _oracle,
  bytes32 _jobId,
  string memory _flight,
  uint256 _departure,
)
  public
  onlyOwner
{
  Chainlink.Request memory req = buildChainlinkRequest(_jobId, this, this.fulfill.selector);
  req.add("flight", _flight);
  req.addUint("departure", _departure);
  sendChainlinkRequestTo(_oracle, req, oraclePayment);
}

Here is an example of the fulfill method:

uint256 public result;
function fulfill(bytes32 _requestId, uint256 _result)
  public
  recordChainlinkFulfillment(_requestId)
{
  result = _result;
}
