通过PHP cURL: InvalidSignature实现的Gemini
通过PHP cURL: InvalidSignature实现的Gemini
提问于 2022-08-30 17:20:58
我将下面的Python代码从正式文档(https://docs.sandbox.gemini.com/rest-api/#private-api-invocation)转换为https://docs.sandbox.gemini.com/rest-api/#private-api-invocation，但我总是得到https://docs.sandbox.gemini.com/rest-api/#private-api-invocation错误：
url = "https://api.gemini.com/v1/mytrades"
gemini_api_key = "mykey"
gemini_api_secret = "1234abcd".encode()
t = datetime.datetime.now()
payload_nonce = time.time()
payload = {"request": "/v1/mytrades", "nonce": payload_nonce}
encoded_payload = json.dumps(payload).encode()
b64 = base64.b64encode(encoded_payload)
signature = hmac.new(gemini_api_secret, b64, hashlib.sha384).hexdigest()
request_headers = {
'Content-Type': "text/plain",
'Content-Length': "0",
'X-GEMINI-APIKEY': gemini_api_key,
'X-GEMINI-PAYLOAD': b64,
'X-GEMINI-SIGNATURE': signature,
'Cache-Control': "no-cache"
}
response = requests.post(url, headers=request_headers)我的PHP代码是这样的，一切看起来都是正确的：
$b64 = base64_encode(utf8_encode(json_encode([ "request" => "/v1/balances", "nonce" => time() ])));
$header = [
'Content-Type: text/plain',
'Content-Length: 0',
'X-GEMINI-APIKEY: master-XXXXXXX',
'X-GEMINI-PAYLOAD: ' . $b64,
'X-GEMINI-SIGNATURE: ' . md5(hash_hmac('sha384', utf8_encode('XXXXXXXXXX'), $b64)),
'Cache-Control: no-cache'
];
$ch = curl_init('https://api.sandbox.gemini.com/v1/balances');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
echo curl_exec($ch);错误：

我没有任何访问API的权限，但请您试一下以下几个字符：
- 从签名计算中删除MD5函数。PHP中的
hash_hmac函数在默认情况下已经这样做了.
'X-GEMINI-SIGNATURE: ' . hash_hmac('sha384', utf8_encode('XXXXXXXXXX'), $b64),- 在有效载荷和同一行中的键之间切换：
'X-GEMINI-SIGNATURE: ' . hash_hmac('sha384', $b64, utf8_encode('XXXXXXXXXX')),页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
