Google Script - REST API:n yksityiset päätepisteet

Viimeksi päivitetty: 1.4.2025

REST-rajapintamme todennetut päätepisteet ovat käytettävissä yksinkertaisella HTTP-pyynnöllä (aivan kuten verkkosivua pyydetään verkkoselaimen kautta), joten API-asiakasohjelma markkinatiedon tuomiseksi Google Sheets -taulukkoon voidaan toteuttaa vain muutamalla rivillä Google Script -koodia.

Asennus

  1. 1

    Luo uusi Google Sheets -taulukko tai avaa olemassa oleva taulukko.

  2. 2

    Avaa komentosarjaeditori valikosta Laajennukset -> Apps Script.

  3. 3

    Poista näkyvissä oleva oletuskoodi (esimerkiksi Valitse kaikki ja sitten Poista/Askelpalautin).

  4. 4

    Kopioi ja liitä Google Script API -koodi (näkyy alla) komentosarjaeditoriin.

  5. 5

    Päivitä esimerkin API-avain käyttämään Kraken-tilisi API-avainta.

  6. 6

    Valinnainen - Lisää tarvittaessa muita mukautettuja funktioita (esimerkiksi eri päätepisteiden kutsumiseen tai eri JSON-kenttien palauttamiseen).

  7. 7

    Tallenna Google Script -koodi

    (Tallenna projekti) -kuvakkeen kautta.

Käyttö

KAPI_Private()-funktio vastaa asianmukaisen URL-osoitteen luomisesta, todennusallekirjoituksen laskemisesta ja HTTP-pyynnön tekemisestä rajapintaan. KAPI_Private()-funktiota voidaan kutsua suoraan kirjoittamalla seuraava (tai vastaava riippuen tilitunnuksesta, päätepisteestä ja parametreista) Google Sheets -soluun:

bash

Bash

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

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

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

KAPI_Private()-funktio palauttaa alkuperäisen JSON-vastauksen rajapinnasta, kuten seuraavan yllä olevassa Balance-päätepiste-esimerkissä:

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"}}

Yksittäisten kenttien/arvojen sijoittamiseksi erillisiin soluihin Google Sheets -taulukossa voidaan kutsua muita mukautettuja funktioita JSON-vastauksen jäsentämiseksi, kuten esimerkin KAPI_Balance()- ja KAPI_OpenOrders()-funktiot:

  • •

    =KAPI_Balance("TEST")

  • •

    =KAPI_OpenOrders("TEST")

bash

Bash

=KAPI_Balance("TEST")

=KAPI_OpenOrders("TEST")

Tämä näyttäisi tulokset seuraavanlaisesti, jolloin tiedot olisivat käytettävissä millä tahansa Google Sheetsin vakiotoiminnoilla (SUM, AVERAGE, COUNT jne.):

Google Script -koodi yksityisille päätepisteille:

Todennusalgoritmi:

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
}

*Huomaa, että kaikki yksityiset päätepisteet vaativat todennusalgoritmin käyttöönottoa.*
