我正在通过POST发送base64文件pdf，但它给我一个错误，这是太长了
代码控制器输入数据，验证输入的数据类型，如果是base64，则分配并发送数据，如果是html，则将其转换为pdf，然后转换为base64，并以json格式返回响应

public function subirResolucion(Request $req){
    $auth = new CeroPapelAuthenticator();
    $auth->setUri(getenv("AUTH_URI"));
    $auth->setSistema(getenv("AUTH_SYSTEM"));
    $auth->setUser(getenv("AUTH_USER"));
    $auth->setPassword(getenv("AUTH_PASS"));

    $response = $auth->access();
    $auth->setToken($response["token"]);
    $auth->setCookie($response["cookie"]);

    $connector = new GestorDocumentalFactory();
    $gd = $connector->crearCeroPapel();

    $id_documento = $req->input("id_documento");
    $transparencia = $req->input("transparencia");
    $base64 = $req->input("base64"); 
    $html = $req->input("html");

    if(!isset($base64))
    {

    $mpdf = new \Mpdf\Mpdf();
    $mpdf->WriteHTML($html);

    $pdfAbase64= base64_encode($mpdf->Output());
    $gd->setArchivo($pdfAbase64);
    }else{
    $gd->setArchivo($base64);
    }

    $gd->setIdDocumento($id_documento);
    $gd->setTransparencia($transparencia);
    $gd->setSistema("erp");
    $gd->setAuth($auth);
    $gd- 
    >setUri(getenv("SERVICE_URI")."/api/indap/ws2_obtener.php");
     try {
         $subirResolucion = $gd->subirResolucion();
         return response()->json(
              $subirResolucion 
         );
     } catch (\Exception $e) {
         return response()->json([
             "status" => "401",
             "mensaje" => "Ocurrió un error al enviar los 
     mensajes 
     ".$e->getMessage()
         ]);
     }
     }

通过POST将数据发送到另一个系统的型号

public function subirResolucion()
{

    $filter = [
        'sistema' => $this->getSistema(),
        'id_documento' => $this->getIdDocumento(),
        'transparencia' => $this->getTransparencia(),
        'archivo' => $this->getArchivo(),  
    ];

    $url = $this->getUri() . '?data=' . (string) 
    json_encode($filter);
    SysLogger::info("Request URI", print_r($url, true));

    $header = [ 
        "Content-Type: application/json",
        "Authorization: Token ".$this->auth->getToken(),
        "Cookie: ".$this->auth->getCookie()
    ];
    SysLogger::info("Headers to be sent", print_r($header, 
    true));

    $response = Page::post($url, [], '', $header);
     print_r($response);
    SysLogger::info("Full response", print_r($response, true));

    $body = json_decode($response['body']);
   // print_r($body);
    SysLogger::info("Body", print_r($body, true));

    return $body;

}

这是一个page.php类
如果有人可以帮我发送数据，它仍然会给我一个错误，希望这段代码可以帮助
