我试过将该方法转换为PHP代码，但它总是返回“至少需要一个aggregateby”。
PHP代码在这里

<?php
$token_type = 'Bearer';
$access_token = 'ya29.xxxxxxxxxxxxxxxxxxxxxxxxxxxxx';  // must change to yours token
$curl = curl_init();

curl_setopt_array($curl, array(
    CURLOPT_URL => 'https://fitness.googleapis.com/fitness/v1/users/me/dataset:aggregate',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_HTTPHEADER  =>  array('Authorization: ' . $token_type .' ' . $access_token),
    CURLOPT_CUSTOMREQUEST => 'POST',
    CURLOPT_POSTFIELDS =>'{
        "aggregateBy": [{
          "dataSourceId":
            "derived:com.google.step_count.delta:com.google.android.gms:estimated_steps"
        }],
        "bucketByTime": { "durationMillis": 86400000 },
        "startTimeMillis": 1659283200000,
        "endTimeMillis": 1659628799000
    }',
));

$response = curl_exec($curl);
curl_close($curl);
print_r($response);

错误请求/响应：

{
  "error": {
    "code": 400,
    "message": "Require at least one aggregateby",
    "errors": [
      {
        "message": "Require at least one aggregateby",
        "domain": "global",
        "reason": "invalidArgument"
      }
    ],
    "status": "INVALID_ARGUMENT"
  }
}

是否有人有变通方案，示例是什么？
