Binance API Hmac签名 [英] Binance API Hmac Signature

问题描述

请帮助我不知道我的代码有什么问题. 不需要签名的端点可以正常工作，所以我想我如何获得签名是一个问题.我收到此错误:

please help I don't know what is wrong with my code. Endpoints that doesn't need signature work fine, so I guess is a problem with how I am getting the signature. I am getting this error:

data: { code: -2014, msg: 'API-key format invalid.' } } }

API文档: https://github.com/binance-exchange/binance-official-api-docs/blob/master/rest-api.md

SIGNED端点需要一个附加参数，签名为 在查询字符串或请求正文中发送.端点使用HMAC SHA256 签名. HMAC SHA256签名是带密钥的HMAC SHA256 手术.使用您的secretKey作为键，并使用totalParams作为值 用于HMAC操作.签名不区分大小写. totalParams定义为与 请求正文.

SIGNED endpoints require an additional parameter, signature, to be sent in the query string or request body. Endpoints use HMAC SHA256 signatures. The HMAC SHA256 signature is a keyed HMAC SHA256 operation. Use your secretKey as the key and totalParams as the value for the HMAC operation. The signature is not case sensitive. totalParams is defined as the query string concatenated with the request body.

我的代码:

const axios = require('axios');
const crypto = require('crypto');
const qs = require('qs');

const binanceConfig = {
  API_KEY: 'XXXXXXX',
  API_SECRET: 'XXXXXX',
  HOST_URL: 'https://api.binance.com',
};

const buildSign = (data, config) => {
  return crypto.createHmac('sha256', config.API_SECRET).update(data).digest('hex');
};

const privateRequest = async (data, endPoint, type) => {
  const dataQueryString = qs.stringify(data);
  const signature = buildSign(dataQueryString, binanceConfig);
  const requestConfig = {
    method: type,
    url: binanceConfig.HOST_URL + endPoint + '?' + dataQueryString + '&signature=' + signature,
    headers: {
      'Authorization': `X-MBX-APIKEY: ${binanceConfig.API_KEY}`,
    },
  };

  try {
    console.log('URL: ', requestConfig.url);
    const response = await axios(requestConfig);
    console.log(response);
    return response;
  }
  catch (err) {
    console.log(err);
    return err;
  }
};

const data = {
  symbol: 'ARKBTC',
  recvWindow: 20000,
  timestamp: Date.now(),
};

privateRequest(data, '/api/v3/openOrders', 'GET');

推荐答案

尝试将headers对象设置为直接具有X-MBX-APIKEY键:

Try setting the headers object to have a key of X-MBX-APIKEY directly:

headers: {
  'X-MBX-APIKEY': binanceConfig.API_KEY,
},
