从node-soap获取响应状态代码

Question

我想在nodejs app中的客户端getRoleListOfUser函数中获取soap响应的状态代码。

 return new Promise((resolve, reject) => {
        soap.createClient(url, function(err, client) {
            if (err){
                console.log(err);
                reject ({ error: true });
            }
            client.setSecurity(new soap.BasicAuthSecurity('admin', 'admin'));
            client.getRoleListOfUser(args, function(err, result) {
                if(err){
                    console.log(err);
                    reject ({ error: true });
                }
                console.log('success');
                resolve ({ message: result });
            });
        });
    });
