Binance API密钥

Question

我已经在Binance上设置了一个只读API键来访问帐户信息，比如货币余额，但是我看不到JSON数据。我在URL中放置的字符串查询返回以下错误：

{“代码”：-2014，"msg":"API-key格式无效。“}

我使用的URL是：https://api.binance.com/api/v3/account?X-MBX-APIKEY=**key**&signature=**s-key**

Binance的文档可以在这里找到：https://www.binance.com/restapipub.html。我做错什么了？

Answer 1

Binance的websocket使用起来有点棘手。此外，也没有办法使用秘密密钥。

常用

1. 将HTTP请求以机密API密钥作为X-MBX-APIKEY头发送到https://api.binance.com/api/v1/userDataStream
2. 您将获得用于websocket连接的侦听键。有一个小时的时间。{"listenKey"：“您的监听键在这里”}
3. 连接到Binance的websocket时使用它

wss://stream.binance.com:9443/ws/{your listen key here}

Python示例

import ssl
from websocket import create_connection

import requests

KEY = 'your-secret-key'
url = 'https://api.binance.com/api/v1/userDataStream'
listen_key = requests.post(url, headers={'X-MBX-APIKEY': KEY})['listenKey']
connection = create_connection('wss://stream.binance.com:9443/ws/{}'.format(KEY), 
                               sslopt={'cert_reqs': ssl.CERT_NONE})

你把它放在头上。下面是从jaggedsoft二进制PHP库借用的PHP工作示例，它是一个签名请求，将返回帐户状态。

$api_key = "cool_key";
$secret = "awesome_secret";

$opt = [
  "http" => [
    "method" => "GET",
    "header" => "User-Agent: Mozilla/4.0 (compatible; PHP Binance API)\r\nX-MBX-APIKEY: {$api_key}\r\n"
  ]
];
$context = stream_context_create($opt);
$params['timestamp'] = number_format(microtime(true)*1000,0,'.','');
$query = http_build_query($params, '', '&');
$signature = hash_hmac('sha256', $query, $secret);
$endpoint = "https://api.binance.com/wapi/v3/accountStatus.html?{$query}&signature={$signature}";

$res = json_decode(file_get_contents($endpoint, false, $context), true);
