php post request parameter authentication error

---

foreword

折磨了我一个下午
Today, I connected with a third-party authentication and verification interface, but it has not passed. After checking various reasons, I finally found that the data parameter did not have json_encode encoding, which caused it to fail to receive it, and the verification failed. I always thought that the request header did not pass the signature. ...

1. Code

1. post request

//发送post请求-使用自带的curl
    public static function PostDateByCurl($url, $headers, $data, $isSave = false)
    {
    
    
        $ch = curl_init();

        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS,json_encode($data));

        //header设置示例
        //$headers = array();
        //$headers[] = 'User-Agent: Apipost client Runtime/+https://www.apipost.cn/';
        //$headers[] = 'Authorization: MTE2MjQ5NzY6MjAyMjEwMDgxNjIwMDM=';
        //$headers[] = 'Content-Type: application/json';

        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

        $result = curl_exec($ch);
        if (curl_errno($ch)) {
    
    
            echo 'Error:' . curl_error($ch);
        }
        
        if ($isSave) {
    
    
            Log::WriteToFile("PostDateByCurl", "url:" . $url . ";\nheaders：" . json_encode($headers) . ";\ndata：" . json_encode($data) . ";\nresult：" . $result);
        } else {
    
    
            Log::WriteToFile("PostDateByCurl", "url:" . $url . ";\nheaders：" . json_encode($headers) . ";\ndata：" . json_encode($data));
        }
        curl_close($ch);

        $_resultData = json_decode($result);
        return json_encode($_resultData);
    }

2. Test call

//线索池鉴权测试
function test1(){
    
    
    $_timestamp='20221008162003';//date('YmdHis');
    //获取签名
    $_sgin=WxFun::GetXscSgin($_timestamp);
    $_auth_token=WxFun::GetXscAuthToken($_timestamp);

    $_appId="11624976";
    $_secret="xxx";
    
    $_date_array=array(
        "appId"=>$_appId,
        "secret"=>$_secret,
        "timestamp"=>$_timestamp,
        "auth_token"=>$_auth_token,
        "sign"=>$_sgin
    );

    $headers = array();
    $headers[] = 'Authorization: MTE2MjQ5NzY6MjAyMjEwMDgxNjIwMDM=';
    $headers[] = 'Content-Type: application/json';

    $_url="http://xxx/v1/{
      
      $_appId}/auth";

    $_result=WxFun::PostDateByCurl($_url,$headers,$_date_array,true);

    return $_result;

}
