Skrip Google - Titik Akhir Peribadi REST API

Terakhir dikemas kini: 1 April 2025

Titik akhir disahkan REST API kami boleh diakses melalui permintaan HTTP yang mudah (sama seperti halaman web diminta melalui pelayar web), jadi klien API untuk mengimport data pasaran ke dalam Google Sheet boleh dilaksanakan dengan hanya beberapa baris kod Google Script.

Pemasangan

  1. 1

    Cipta Google Sheet baharu atau buka helaian sedia ada.

  2. 2

    Buka editor skrip melalui menu Extensions -> Apps Script.

  3. 3

    Padamkan kod lalai yang ditunjukkan (contohnya, Select All kemudian Delete/Backspace).

  4. 4

    Salin/Tampal kod Google Script API (ditunjukkan di bawah) ke dalam editor skrip.

  5. 5

    Kemas kini contoh API key untuk menggunakan API key daripada akaun Kraken anda.

  6. 6

    Pilihan - Tambah sebarang fungsi tersuai tambahan yang anda perlukan (untuk memanggil titik akhir yang berbeza, atau mengembalikan medan JSON yang berbeza, contohnya).

  7. 7

    Simpan Kod Google Script melalui ikon

    (Save project).

Penggunaan

Fungsi KAPI_Private() bertanggungjawab untuk mencipta URL yang sesuai, mengira authentication signature, dan membuat permintaan HTTP kepada API. Fungsi KAPI_Private() boleh dipanggil secara langsung dengan memasukkan yang berikut (atau serupa bergantung pada ID akaun, titik akhir, dan parameter) dalam sel Google Sheet:

bash

Bash

=KAPI_Private("TEST", "Balance", "")

=KAPI_Private("TEST", "TradeBalance", "asset=xdg")

=KAPI_Private("TEST", "OpenOrders", "userref=886794735")

Fungsi KAPI_Private() mengembalikan respons JSON asal daripada API, seperti yang berikut untuk contoh titik akhir Balance di atas:

bash

Bash

{"error":[],"result":{"ZUSD":"16.4272","ZEUR":"0.3880","ZJPY":"0.45","KFEE":"10368.39","XXBT":"0.0000000072","XXRP":"0.00000000","XLTC":"0.0000000100","XXDG":"13997.00000000","XXLM":"100.00000000"}}

Untuk meletakkan medan/nilai individu ke dalam sel berasingan dalam Google Sheet, fungsi tersuai tambahan boleh dipanggil untuk menghuraikan respons JSON, seperti contoh fungsi KAPI_Balance() dan KAPI_OpenOrders():

  • •

    =KAPI_Balance("TEST")

  • •

    =KAPI_OpenOrders("TEST")

bash

Bash

=KAPI_Balance("TEST")

=KAPI_OpenOrders("TEST")

Ini akan memaparkan hasil yang serupa dengan yang berikut, di mana data akan boleh diakses oleh mana-mana fungsi Google Sheets standard (SUM, AVERAGE, COUNT, dll.):

Kod Skrip Google Untuk Titik Akhir Peribadi:

Authentication Algorithm:

bash

Bash

API_Public_Key = { 
  'TEST': 'INSERT YOUR API PUBLIC KEY' 
}

API_Private_Key = { 
  'TEST': 'INSERT YOUR API PRIVATE KEY' 
}

function KAPI_Private(acc_id, endpoint, parameters) {
  Utilities.sleep(Math.random() * 100)

  api_key = API_Public_Key[acc_id]
  api_secret = Utilities.base64Decode(API_Private_Key[acc_id])
  api_path = Utilities.newBlob('/0/private/' + endpoint).getBytes()
  api_nonce = Date.now().toString()
  api_post = 'nonce=' + api_nonce + '&' + parameters

  api_sha256 = Utilities.computeDigest(
    Utilities.DigestAlgorithm.SHA_256, 
    api_nonce + api_post
  )
  api_hmac = Utilities.computeHmacSignature(
    Utilities.MacAlgorithm.HMAC_SHA_512, 
    api_path.concat(api_sha256), 
    api_secret
  )
  api_signature = Utilities.base64Encode(api_hmac)

  http_options = {
    'method': 'post', 
    'payload': api_post, 
    'headers': {
      'API-Key': api_key, 
      'API-Sign': api_signature
    }
  }
  http_response = UrlFetchApp.fetch(
    'https://api.kraken.com/0/private/' + endpoint, 
    http_options
  )
  api_data = http_response.getContentText()
  return api_data
}

Untuk menggunakan skrip berikut dengan Authentication Algorithm di atas, hanya tambahkan fungsi pada skrip di atas.

*Sila ambil perhatian bahawa semua Private Endpoints memerlukan pelaksanaan Authentication Algorithm.*
