Question

我是API的新手，非常感谢您的建议。我想回想Binance API“ GET / api / v3 / account（HMAC SHA256）”，以仅获取我帐户中可用的免费资产。

我得到的代码的响应是这样的：

{
  "makerCommission": 15,
  "takerCommission": 15,
  "buyerCommission": 0,
  "sellerCommission": 0,
  "canTrade": true,
  "canWithdraw": true,
  "canDeposit": true,
  "updateTime": 123456789,
  "accountType": "SPOT",
  "balances": [
    {
      "asset": "BTC",
      "free": "4723846.89208129",
      "locked": "0.00000000"
    },
    {
      "asset": "LTC",
      "free": "4763368.68006011",
      "locked": "0.00000000"
    }
  ],
    "permissions": [
    "SPOT"
  ]
}

我只想要自由结余，因此我尝试使用MAP方法，但出现此错误：

Cannot read property 'map' of undefined at Object.<anonymous><C:\Users\etc..
at Module._compile (internal/module/cjs/loader.js1137:30)
at Object.Module._extensions..js (internal/modules/cjs/loader.js:1157:10)

at Function.executeEntryPoint [as runMain] (internal/modules/run_main.js:71:12)
at internal/run_main_module.js:17:47

遵循我的代码：

    const crypto = require('crypto');
    var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
    var burl = "https://api.binance.com";
    var endPoint = "/api/v3/account";
    var dataQueryString = "timestamp=" + Date.now();
    var keys = {
        "APIkey" :'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA',
        "SECRETkey" : 'BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB'
        }
    var signature = crypto.createHmac('sha256',keys['SECRETkey']).update(dataQueryString).digest('hex');
    var url = burl + endPoint + '?' + dataQueryString + '&signature=' + signature;
    var ourRequest = new XMLHttpRequest();
    ourRequest.open('GET',url,true);
    ourRequest.setRequestHeader('X-MBX-APIKEY', keys['APIkey']);
    let arrayCleaned = ourRequest.responseText.balances.map(ele => {
            return {
                "asset" : ele.asset,
                "free" : ele.free
            }
        })
    console.log(arrayCleaned);
    ourRequest.send();

在此先感谢大家的帮助。

我猜您必须是AJAX的新手，因为您缺少2个重要事实

AJAX需要时间
AJAX响应始终是字符串

考虑您的代码段

var ourRequest = new XMLHttpRequest();
ourRequest.open('GET',url,true);   
//           ^---- doesn't actually send any request https://stackoverflow.com/q/29362977/6160662
ourRequest.setRequestHeader('X-MBX-APIKEY', keys['APIkey']);
let arrayCleaned = ourRequest.responseText.balances.map(ele => {  //Line 4
        return {
            "asset" : ele.asset,
            "free" : ele.free
        }
    })
console.log(arrayCleaned);
ourRequest.send(); //Line 11

如您所见，您正在第11行发送ajax请求，但是您试图在第4行处理（预期）数据！因此出现错误Cannot read property 'map' of undefined at Object

接下来的事情是ourRequest.responseText是将服务器响应保存在 string 中的属性，它没有任何map属性。因此，您需要使用JSON.parse()

将其转换为对象

所以这应该很好

var ourRequest = new XMLHttpRequest();
ourRequest.open('GET',url,true);
ourRequest.setRequestHeader('X-MBX-APIKEY', keys['APIkey']);

var arrayCleaned = [];
ourRequest.onload = function () {
    // Convert data string to an object
    var data = JSON.parse(ourRequest.responseText); // string -->to Object

    arrayCleaned = data.balances.map(ele => {
        return {
            "asset" : ele.asset,
            "free" : ele.free
        }
    })
    console.log(arrayCleaned);
};

ourRequest.send();

您是否尝试过使用CCXT连接到币安API？

您可以执行以下操作：

;(async () => {
    const binance = ccxt.binance ({'apiKey': 'YOURAPIKEY', 'secret': 'YOURSECRET'})
    const balance = await binance.fetchBalance ()
    const free = balance['free']
    console.log (free)
}) ()

我不知道我是否理解您的问题，但我创建了自己的脚本来使用 python 跟踪我的投资组合。这可能会有所帮助：

    from binance.client import Client

def editar_df_binance(lista):
    df = pd.DataFrame(lista)
    df["free"] = df["free"].astype(float)  #Convertimos las columnas a valores float
    df["locked"] = df["locked"].astype(float)  #Convertimos las columnas a valores float
    filtro1 = df["free"] > 0
    filtro2 = df["locked"] > 0
    df = df[filtro1 | filtro2]
    df["Fecha"] = hoy
    df = df.rename(columns={"asset": "Moneda", "free": "Saldo", "locked": "Bloqueado"}).sort_values(by="Saldo", ascending=False)  #Renombramos y ordenamos
    df["Moneda"] = df["Moneda"].apply(editar_moneda_binance)  #Vamos a corregir el nombre de las monedas de earn que aparecen con "LD"
    df = df[["Fecha", "Moneda", "Saldo", "Bloqueado"]]

    return df
    
def editar_moneda_binance(moneda):
    if moneda.startswith("LD"):
        return moneda.replace("LD", "")
    return moneda
    
    
if __name__ == '__main__':
    ###############Balance Binance###################  (Falta la parte de earn)
    api_key = os.environ.get('binance_api')
    api_secret = os.environ.get('binance_secret')
    client = Client(api_key, api_secret)
    diccionario = client.get_account()["balances"]  #Obtener valores de balance
    df_binance = editar_df_binance(diccionario)

然后我用数据框创建一个excel文件。请注意不显示 Binance Earn。

我已经尝试了上面的解决方案，但是遇到了同样的错误。这里的代码

const crypto = require('crypto');
    var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
    var burl = "https://api.binance.com";
    var endPoint = "/api/v3/account";
    var dataQueryString = "timestamp=" + Date.now();
    var keys = {
        "APIkey" :'AAAAAAAAAAA',
        "SECRETkey" : 'BBBBBBBBBBB'
        }
    var signature = crypto.createHmac('sha256',keys['SECRETkey']).update(dataQueryString).digest('hex');
    var url = burl + endPoint + '?' + dataQueryString + '&signature=' + signature;
    var ourRequest = new XMLHttpRequest();
    ourRequest.open('GET',url,true);
    ourRequest.setRequestHeader('X-MBX-APIKEY', keys['APIkey']);
    var arrayCleaned = [];
    ourRequest.onload = function(){
        //Convert data string string to an object
        var data = JSON.parse(ourRequest.responseText); // string --> to Object
        arrayCleaned = data.balances.map(ele => {
            return {
                "asset" : ele.asset,
                "free" : ele.free
                } 
             }) 
        console.log(arrayCleaned);
  };
ourRequest.send();
