FlightAware Chainlink (Testnet)

This Chainlink has a dedicated connection to FlightAware.

Steps for using this oracle

Write and deploy your Chainlink contract using the network details provided.
Fund the contract with LINK.
Call your request method.

Chainlink Network Details

Use the following addresses and Job IDs for the Kovan network to create requests:

LINK Token address: 0xa36085f69e2889c224210f603d836748e7dc0088
Oracle address: 0x2f90A6D021db21e1B2A077c5a37B3C7E75D15b7e
JobID: a644d4e30977459d9a596bef89c09e71
Sleep JobID: f0003b2c52024e7fa931d6ee9a947c87

Create your Chainlink contract

To inherit Chainlink behavior, you must import ChainlinkClient.sol.

Basic Contract Structure (Solidity 0.6.0):

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...
}

Tasks

The oracle performs the following tasks:

FlightAware
Copy
Ethuint256
EthTx

Request Parameters

endpoint: The endpoint to query (optional, defaults to FlightInfoEx).
flight: The flight identification or number (required).
departure: The unix timestamp of the departure (required).
until: Required for the Sleep job.

Solidity Code Examples for Parameters:

req.add("endpoint", "FlightInfoEx");
req.add("flight", "NAX105");
req.addUint("departure", 1594378824);
req.addUint("until", now + 1 hours);

Chainlink Examples

The createRequest Method:

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

The fulfill Method:

uint256 public result; 

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