brew install flow-cli
sh -ci "$(curl -fsSL https://storage.googleapis.com/flow-cli/install.sh)"
flow cadence install-vscode-extension

1.プロジェクト作成

$ mkdir pinata-party
$ cd pinata-party
$ flow project init
$ flow accounts create
$ flow accounts get 0x01cf0e2f2f715450

2.ディレクトリとファイルを下記のように作成
contract...実行したアカウントのストレージにdeployされる
transaction...実行したアカウントで、デプロイ済のコントラクトを操作する
script...ストレージの状態をReadする

cadence
    |-contracts
        |-PinataPartyContract.cdc
flow.json   
scripts
    |-CheckTokenMetadata.cdc
transactions
    |-MintPinataParty.cdc

3.flow.jsonを整形

"contracts": {
     "PinataPartyContract": "./cadence/contracts/PinataPartyContract.cdc"
}
"deployments": {
     "emulator": {
          "emulator-account": ["PinataPartyContract"]
     }
}

4.PinataPartyContract.cdcを作成。下記をcopy

https://gist.github.com/polluterofminds/17e961796b795a4c001c2e644bda6a41

5.Contractのdeployを行う

$flow project start-emulator
$flow project deploy --network=emulator

6.MintPinataParty.cdcを作成

https://gist.github.com/polluterofminds/35f6b46abe8ad59237e491b280d30665

7.keyの生成
$flow keys generate

8.mint - transactionの実行
flow transactions send --code ./transactions/MintPinataParty.cdc --signer emulator-account


9.CheckTokenMetadata.cdcの作成

import PinataPartyContract from 0xf8d6e0586b0a20c7

pub fun main() : {String : String} {
    let nftOwner = getAccount(0xf8d6e0586b0a20c7)
    // log("NFT Owner")    
    let capability = nftOwner.getCapability<&{PinataPartyContract.NFTReceiver}>(/public/NFTReceiver)

    let receiverRef = capability.borrow()
        ?? panic("Could not borrow the receiver reference")

    return receiverRef.getMetadata(id: 1)
}

10.実行
flow scripts execute ./scripts/CheckTokenMetadata.cdc

11.成功！
Result: {"name": "The Big Swing", "swing_velocity": "29", "swing_angle": "45", "rating": "5", "uri": "ipfs://QmRZdc3mAMXpv6Akz9Ekp1y4vDSjazTx2dCQRkxVy1yUj6"}

1. keyを作成する
$flow keys generate

2. publickeyをfaucetに登録して、addressを登録する
https://testnet-faucet-v2.onflow.org/

3. cliを通じて、アカウントに1000flowがあることを確認する
$flow accounts get 0x5262a052b4e278ae --network=testnet

4. flow.jsonに取得したaddressとkey(pk)を記述する

    "accounts": {
        "emulator-account": {
            "address": "",
            "keys": "",
            "chain": "flow-emulator"
        },
        "testnet-account": {
            "address": "",
            "keys": "",
            "chain": "flow-testnet"
        }
    },

5.flow.jsonのdeploymentにtestnetの項目をたす

    "deployments": {
        "emulator": {
            "emulator-account": ["PinataPartyContract"]
        },
        "testnet": {
            "testnet-account": ["PinataPartyContract"]
        }
    }

6. deployする
flow project deploy --network=testnet

(balanceが減る)
Balance  1000.00100000
->
Balance  1000.00099000

7. mintする
$ flow transactions send ./transactions/MintPinataParty.cdc --network=testnet --signer testnet-account

8. チェックする
$ flow scripts execute ./scripts/CheckTokenMetadata.cdc --network=testnet 

// npm install onflow/fcl --save

const fcl = require('@onflow/fcl');

(async () => {
  fcl.config()
  .put("accessNode.api", 'https://access-testnet.onflow.org');

  const resp = await fcl.send([
    fcl.script(`
      import DemoContract from xxxxxxxxxx

      pub fun main(): {String: String}? {
        let nftOwner = getAccount(xxxxxxxxxx) 
        let capability = nftOwner.getCapability<&{DemoContract.NFTReceiver}>(/public/NFTReceiver)
        let receiverRef = capability.borrow()
          ?? panic("Could not borrow the receiver reference")

        return receiverRef.getMetadata(id: 1)
      }
    `)
  ]);

  const result = await fcl.decode(resp);
  console.log(result);
})();
