Bitpanda API授权失败：PHP Curl转写及修复求助

问题说明 #

尝试使用PHP Curl调用Bitpanda API查询加密资产时，请求失败并返回401未授权错误，提示凭证/访问令牌错误。现有可正常运行的PowerShell脚本，需转写为PHP，或提供JavaScript实现方案。

错误信息 #

{"errors":[{"status":401,"code":"unauthorized","title":"Credentials/Access token wrong"}]}

官方API示例 #

curl -X GET "https://api.bitpanda.com/v1/trades" \
    -H "X-API-KEY: string"

失效的PHP代码 #

$service_url = "https://api.bitpanda.com/v1/trades";
$curl_session = curl_init($service_url);

curl_setopt($curl_session, CURLOPT_USERPWD, $apiKey);
curl_setopt($curl_session, CURLOPT_HTTPHEADER, ['content-type: application/json']);
curl_setopt($curl_session, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($curl_session);
curl_close($curl_session);
echo $result;

可用的PowerShell脚本 #

$key = "APIKEY"
$trades = Invoke-WebRequest -Uri "https://api.bitpanda.com/v1/trades" -Headers @{"X-API-KEY" = $key} -UseBasicParsing
$tdata = $trades.Content | ConvertFrom-Json
$tdata.data.attributes | Out-GridView

修正后的PHP代码 #

原代码错误在于使用了CURLOPT_USERPWD（Basic认证方式），但Bitpanda API要求通过X-API-KEY请求头传递密钥。修正后的代码如下：

$apiKey = "你的API密钥";
$service_url = "https://api.bitpanda.com/v1/trades";

$curl_session = curl_init($service_url);

// 设置包含X-API-KEY的请求头
curl_setopt($curl_session, CURLOPT_HTTPHEADER, [
    'Content-Type: application/json',
    "X-API-KEY: $apiKey"
]);
curl_setopt($curl_session, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($curl_session);
// 可选：检查Curl请求错误
if(curl_errno($curl_session)) {
    echo 'Curl错误: ' . curl_error($curl_session);
}
curl_close($curl_session);

echo $result;

JavaScript解决方案 #

浏览器端Fetch实现 #

const apiKey = "你的API密钥";
const url = "https://api.bitpanda.com/v1/trades";

fetch(url, {
    method: 'GET',
    headers: {
        'Content-Type': 'application/json',
        'X-API-KEY': apiKey
    }
})
.then(response => {
    if(!response.ok) throw new Error('请求失败');
    return response.json();
})
.then(data => {
    console.log(data.data.attributes);
    // 此处可添加数据处理逻辑
})
.catch(error => console.error('错误:', error));

Node.js环境实现（依赖node-fetch） #

先安装依赖：

npm install node-fetch

编写代码：

const fetch = require('node-fetch');

const apiKey = "你的API密钥";
const url = "https://api.bitpanda.com/v1/trades";

fetch(url, {
    method: 'GET',
    headers: {
        'Content-Type': 'application/json',
        'X-API-KEY': apiKey
    }
})
.then(response => {
    if(!response.ok) throw new Error('请求失败');
    return response.json();
})
.then(data => {
    console.log(data.data.attributes);
})
.catch(error => console.error('错误:', error));
