アカウント情報

これまでアカウントの情報はnem2-cliを使って取得していました。

ここではコードも用いて情報の取得をしてみましょう。

アカウント情報の取得

account/fetch_account_info.jsを実行してください。

$ node account/fetch_account_info.js
AccountInfo {
  meta:
   AccountMetaDTO {
     height: undefined,
     hash: undefined,
     merkleComponentHash: undefined,
     index: undefined,
     id: undefined },
  address:
   Address {
     address: 'SAFPLKSQJTYGTWKNJ6B66LJV3VRBMUSBQH7Y6ZH4',
     networkType: 144 },
  addressHeight: UInt64 { lower: 298, higher: 0 },
  publicKey:
   'A29FE98485D2841C7C68A2B521156EE5D0170FF6AFF2ED3BF4E908500EC083B0',
  publicKeyHeight: UInt64 { lower: 382, higher: 0 },
  mosaics:
   [ Mosaic {
       id:
        MosaicId { id: Id { lower: 2100741038, higher: 1065721635 } },
       amount: UInt64 { lower: 2471032704, higher: 1 } },
     Mosaic {
       id: MosaicId { id: Id { lower: 2950193148, higher: 191824161 } },
       amount: UInt64 { lower: 3000, higher: 0 } },
     Mosaic {
       id: MosaicId { id: Id { lower: 1557790320, higher: 326653477 } },
       amount: UInt64 { lower: 2990, higher: 0 } },
     Mosaic {
       id: MosaicId { id: Id { lower: 538523231, higher: 700909375 } },
       amount: UInt64 { lower: 1000, higher: 0 } },
     Mosaic {
       id: MosaicId { id: Id { lower: 149426422, higher: 1878724419 } },
       amount: UInt64 { lower: 10000, higher: 0 } },
     [length]: 5 ],
  importance: UInt64 { lower: 0, higher: 0 },
  importanceHeight: UInt64 { lower: 0, higher: 0 } }

アカウントに関する情報が取得できました。

保有するモザイクも含まれます。

しかしこの情報にはモザイクIDと絶対値の保有量しか含まれておらず、可分性による相対的な量を計算することができません。

コード解説

Addressオブジェクトを作ったら、AccountHttp#getAccountInfoメソッドに渡して購読を開始することでアカウント情報のオブジェクトが取得できます。

accountHttp.getAccountInfo(address)
  .subscribe(accountInfoView => {
    console.log('%o', accountInfoView);
  })
;

しかし、このメソッドだけではモザイクごとの詳細な情報は含まれていません。

保有モザイクの定義情報の取得

account/fetch_owned_mosaics.jsを実行してください。

今度は保有しているモザイクとその詳細な定義情報を取得しました。

MosaicServiceというサービスクラスを用いることで、アカウントが保有するモザイク情報の詳細を取得できます。

アカウント情報と保有モザイク情報を同時に取得

fetch_account_info_with_mosaics.jsを実行してください。

これはrxjsの応用による、その2つをあわせて扱う場合のコードです。

このコードはアドレスの保有するモザイクを定義情報付きで取得します。

MosaicAmountViewでラップされたオブジェクトにはrelativeAmount()というメソッドが用意されているので、これを実行することで相対量を取得することが出来ます。

他にもmosaicInfoプロパティに定義情報が含まれているので、必要に応じて利用することが出来ます。

コード解説

MosaicServiceというサービスクラスを用いることで、アカウントが保有するモザイク情報の詳細を取得できます。

const accountHttp = new AccountHttp(url);
const mosaicHttp = new MosaicHttp(url);
const mosaicService = new MosaicService(accountHttp, mosaicHttp);

// アカウント情報と保有モザイク情報を組み合わせる
accountHttp.getAccountInfo(address)
  .pipe(
    mergeMap(account => mosaicService.mosaicsAmountViewFromAddress(account.address)
      .pipe(
        mergeMap(_ => _),
        toArray(),
        map(mosaics => ({ account, mosaics }))
      ),
    )
  )
;

使用するメソッドは前述の2つのコードでもでてきたAccountHttp#getAccountInfoとMosaicService#AmountViewFromAddressです。

rxjsのpipeメソッドを使い、ストリームを流れてきたアカウント情報を、より内側のモザイク情報の取得結果のタイミングで組み合わせ、最終的にsubscribeで取得するような流れを作っています。

トランザクションの取得

アカウントに関するトランザクションのAPIは、公開鍵を指定することで取得することが出来ます。

account/fetch_transactions.jsを実行します。

このスクリプトは受信トランザクション、送信トランザクション、未承認トランザクションそれぞれをまとめて取得します。

第一引数に取得したいアドレスの公開鍵を渡して実行します。

コード解説

AccountHttp#incomingTransactions等のメソッドにPublicAccountオブジェクトを渡して購読すると情報を取得できます。

forkJoin([
  accountHttp.incomingTransactions(publicAccount),
  accountHttp.outgoingTransactions(publicAccount),
  accountHttp.unconfirmedTransactions(publicAccount)
]).pipe(
  map(results => {
    const [ incomings, outgoings, unconfirmed ] = results;
    return { incomings, outgoings, unconfirmed };
  })
).subscribe(
  data => console.log(data)
);

今回はRxJSのforkJoinを用いて受信・送信・未承認をまとめて取得し、トランザクション情報配列をオブジェクトの形にまとめてsubjectへ流しています。

アドレスからトランザクションを取得する

アドレスを指定してトランザクションを取得したい場合もあると思います。

リクエスト回数やコードが若干複雑化しますが、アカウント情報から公開鍵を取得し、その公開鍵でトランザクションを取得するコードを用意しました。

fetch_transactions_by_address.jsを実行します。

ただし、アカウント情報から取得できる公開鍵は、トランザクションをアナウンスして(送信して)初めてネットワーク上に現れます。

そのため受信トランザクションしかない場合は公開鍵がネットワーク上に現れないため、アカウント情報から公開鍵を取得することができません。

(現状の仕様では0000000000000000000000000000000000000000000000000000000000000000という値が返ってきます。)

公開鍵が晒されていないアカウントの受信トランザクションを取得したい場合は公開鍵を直接指定するしかありません。

account,incomings,outgoings,unconfirmedとキーごとにアカウント情報とトランザクション配列を取得して表示しました。

コード解説

まずアドレスからアカウント情報を取得しています。

取得してきたアカウント情報から公開鍵を取り出して、トランザクションの取得APIへ渡しています。

今回は受信・送信・未承認に加えてアカウント情報をオブジェクトの形にまとめてsubjectへ流しています。

accountHttp.getAccountInfo(address).pipe(
  mergeMap(accountInfo => {
    let observers = [];
    if(address.equals(accountInfo.address)) {
      observers = [
        accountHttp.incomingTransactions(accountInfo.publicAccount),
        accountHttp.outgoingTransactions(accountInfo.publicAccount),
        accountHttp.unconfirmedTransactions(accountInfo.publicAccount),
      ];
    } else {
      observers = [
        of([]),
        of([]),
        of([]),
      ];
    }
    return forkJoin([of(accountInfo)].concat(observers));
  }),
  map(results => {
    const [ account, incomings, outgoings, unconfirmed ] = results;
    return { account, incomings, outgoings, unconfirmed };
  })
).subscribe(
  data => console.log(data)
);

公開鍵が取得できなかった場合は、トランザクション配列には空の配列をストリームに流すようにしています。
