此请求的币安签名无效错误

问题描述

我正在努力让 this 工作

这是我得到的错误：

data: { code: -1022,msg: 'Signature for this request is not valid.' }

功能

const crypto = require('crypto')

export async function signature (query_string) {
  return crypto.createHmac('sha256',apiSecret).update(query_string).digest('hex')
}

export async function order (symbol,quantity,price) {    
  const query = '?symbol=' + symbol + '&isIsolated=TRUE&side=BUY&quantity=' + quantity + '&price=' + price + '&type=LIMIT&sideEffectType=MARGIN_BUY&recvWindow=5000&timestamp=' + Date.Now()

  const querySigned = await signature(query)

  const sendingQuery = query + '&signature=' + querySigned

  const queryConfig = {
    method: 'POST',url: 'https://api.binance.com/sapi/v1/margin/order/' + sendingQuery,headers: {
      'X-MBX-APIKEY': apiKey,},}

  const response = await axios(queryConfig)

  return response.data
}

解决方法

请勿在签名输入中包含问号。

const query = 'symbol=' + symbol +  // removed the question mark

const queryConfig = {
    method: 'POST',url: 'https://api.binance.com/sapi/v1/margin/order/?' + sendingQuery,// added the question mark
    headers: {
      'X-MBX-APIKEY': apiKey,},}

来源：我查了一年前同样使用 Binance API 的旧代码，发现作为签名输入传递的问号 (not) 有所不同。

我将它用于现货订单，但我仍会包含它。如果这不是一个正确的解决方案，它可能会帮助您进一步调试。

let query = 'recvWindow=5000&timestamp='+(new Date().getTime()) + "&symbol=" + baseAsset + quoteAsset + "&side=" + side + "&quantity=" + baseAmount + "&type=market";
const signature = crypto.createHmac('sha256',apiSecret).update(query).digest("hex");
query += '&signature='+signature;

const result = await axios({
    'method': 'POST','url': 'https://api.binance.com/api/v3/order?'+query,'headers': {
        'X-MBX-APIKEY': apiKey
    }
});
