Binance TIMESTAMP ERROR（此请求的时间戳在 recvWindow 之外。M 1）

Question

我在执行代码时使用了 binance broker api。

我遇到了这个错误： 数据：{ 代码：-1021，在此输入代码消息：'Timestamp for this request is outside of the recvWindow.' }

然后我使用了 binance server timestamp 并得到另一个错误： 数据：{代码：-1022，消息：'Signature for this request is not valid.'}

----- My sample code -------

'use strict'

//Modules
const crypto = require('crypto');
const axios = require('axios');
const moment = require('moment');
const keys = require('./config/keys');


//Keys
const apiKey = keys.keys.apiKey;

async function api_call(config){
  var response  = {}
  try {
    response = await axios(config);
    response =  {
      error: false,
      data : response.data
    }
  } catch (error) {
    response =  { 
      error: true,
      data : error
    }
  }
  return response;
}


async function get_binance_server_time(recvWindow=50000){
  var timestamp = moment().unix();
  var serverTime = 0;

  var config = {
    method: 'get',
    url: `https://api.binance.com/api/v3/time`,
    headers: { 
      'Content-Type': 'application/json', 
      'X-MBX-APIKEY': apiKey 
    }
  };  
  var response = await api_call(config);

  if(response.error){
    response.data = {
      serverTime : serverTime
    }
  }
  serverTime = response.data.serverTime

  console.log(timestamp);
  console.log(response.data.serverTime);

  if (timestamp < (serverTime + 1000) && (serverTime - timestamp) <= recvWindow) {
    console.log("process");
  } else {
    console.log("Rejected");
  }
  return serverTime;
}


async function get_broker_account_information( _signature = null){

  // Make the api call here
  var serverTime  = await get_binance_server_time();
  var _timestamp = serverTime;

  const query_string = `timestamp=${_timestamp}`;
  const recvWindow = 50000
  const signature = crypto.createHmac('sha256', apiKey).update(query_string).digest('hex')

  var config = {
    method: 'get',
    url: `https://api.binance.com/sapi/v1/broker/info?timestamp=${_timestamp}&signature=${signature}&recvWindow=${recvWindow}`,
    headers: { 
      'Content-Type': 'application/json', 
      'X-MBX-APIKEY': apiKey 
    }
  };  
  
  var response = await api_call(config)
  console.log(response.data);
  return response;
}

// get_binance_server_time()

Binance 需要以毫秒为单位的 Unix 时间戳。所以你应该改变

var timestamp = moment().unix();

到

var timestamp = moment().unix()*1000;

一些时间同步问题可以通过使用大约 15 秒的偏移量来解决：

const offset = 15000;
var timestamp = moment().unix()*1000 - offset;  // works flawlessly in my case

也尝试使用

const recvWindow = 60000  // maximum allowed

重要： 您的签名必须从密钥生成，而不是 api 密钥。 api 密钥 header，签名计算中的密钥。

要生成有效签名，所有查询参数都必须在用于生成签名的查询字符串中。

创建参数object并将其转换为queryString:

var params = {
    'timestamp': _timeStamp,
    'recvWindow: 60000,
    // other query parameters
};

var queryString = Object.keys(params).map(key => key + '=' + params[key]).join('&');

然后生成签名：

const signature = crypto.createHmac('sha256', apiSecret).update(queryString).digest('hex')
