用于Coinbase的api密钥身份验证 [英] Api key authentication for coinbase

问题描述

我正在尝试编写对API coinbase.com的请求，但是我无法正确生成签名.我已经尝试寻找错误2天了，但是我找不到.我在页面上分析了其他语言的代码: https://developers.coinbase .com/docs/wallet/api-key-autumnicathion ，但在实现上没有任何区别.

I'm trying to write a request for API coinbase.com, but I can not correctly generate a signature. I've been trying to find my mistake for 2 days, but I can not. I analyzed the code for other languages on the page: https://developers.coinbase.com/docs/wallet/api-key-autumnicathion but I do not see any differences in implementation.

请帮助我.

<?php
$g_coinbase_key = 'KcxisxqmWRVgtwsj';
$g_coinbase_secret = 'isOLGBLaEkCy3ROQMvmjonGmXK0KRmUS';

$time = time();
$method = "GET";
$path = '/v2/accounts/';
$sign = base64_encode(hash_hmac("sha256", $time.$method.$path, $g_coinbase_secret));
$ch = curl_init('https://api.coinbase.com'.$path);
$headers = array(
    "CB-VERSION: 2017-10-26",
    "CB-ACCESS-SIGN: ".$sign,
    "CB-ACCESS-TIMESTAMP: ".$time,
    "CB-ACCESS-KEY: ".$g_coinbase_key,
    "Content-Type: application/json"
);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
var_dump($result);
?>

结果:

{"errors":[{"id":"authentication_error","message":"invalid signature"}]}

推荐答案

替换

$sign = base64_encode(hash_hmac("sha256", $time.$method.$path, $g_coinbase_secret));

使用

$sign = hash_hmac("sha256", $time.$method.$path, $g_coinbase_secret);

Coibase Api使用hash_mac

Coibase Api uses hash_mac
