问下这个postman对应的php代码如何转换成 HTTP形式？

postman截图

curl_setopt_array($curl, array(
            CURLOPT_URL => 'http://192.168.1.231/v1/api/pubsub/busi/record/query',
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_ENCODING => '',
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 0,
            CURLOPT_FOLLOWLOCATION => true,
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST => 'POST',
            CURLOPT_POSTFIELDS =>'{}',
            CURLOPT_HTTPHEADER => array(
                'Content-Type: application/json',
                'cappkey: appkey1',
                'cnonce: 123456',
                'ctimestamp: 1707187818264',
                'csign: a8e05c6c4d19841783a241c110da6e9e'
            ),
        ));

        $response = curl_exec($curl);
        curl_close($curl);
        echo $response;
这代码是能返回数据的

然后我想把这端代码改成

use Illuminate\Support\Facades\Http;
$request_header = [
            'Content-Type'=>'application/json',
            'cappkey'=>'appkey1',
            'cnonce'=>'123456',
            'ctimestamp'=>'1707187818264',
            'csign'=>'a8e05c6c4d19841783a241c110da6e9e'
        ];
$response = Http::withHeaders($request_header)->withOptions(["verify"=>false])
                    ->asJson()
                    ->timeout(3)
                    ->post('http://192.168.1.231/v1/api/pubsub/busi/record/query',[])->body();
但是我这么写法就报
 [code] => 200008
 [msg] => 签名错误

帮忙看下我写法哪里有问题了？
