Bitfinex取消报价无法正常工作

Question

使用Bitfinex REST API（v1）时出现以下错误

{"message":"Offer could not be cancelled."}

我使用了以下JS代码。我同时尝试了WebSocket版本和REST API，但无法取消已采取的报价。我只能从Bitfinex仪表板关闭它。

以下是JS版本的代码：

const request = require('request')
const crypto = require('crypto')

const apiKey = 'xxxxx'
const apiSecret = 'xxxxxx'
const baseUrl = 'https://api.bitfinex.com'

const url = '/v1/offer/cancel'
const nonce = Date.now().toString()
const completeURL = baseUrl + url
const body = {
  offer_id: 128887529,
  request: url,
  nonce
}
const payload = new Buffer(JSON.stringify(body)).toString('base64')

const signature = crypto.createHmac('sha384', apiSecret).update(payload).digest('hex')

const options = {
  url: completeURL,
  headers: {
    'X-BFX-APIKEY': apiKey,
    'X-BFX-PAYLOAD': payload,
    'X-BFX-SIGNATURE': signature
  },
  body: JSON.stringify(body)
}

request.post(
  options,
  function(error, response, body) {
    console.log('response:', JSON.stringify(body, 0, 2))
  }
)
