    {
        if (true === $method) {
            // 获取原始请求类型
            return $this->server('REQUEST_METHOD') ?: 'GET';

修改为

public function method($method = false)
    { if (true === $method) { // 获取原始请求类型 return $this->server('REQUEST_METHOD') ?: 'GET';
        } elseif (!$this->method) { if (isset($_POST[Config::get('var_method')])) { $method = strtoupper($_POST[Config::get('var_method')]); if (in_array($method, ['GET', 'POST', 'DELETE', 'PUT', 'PATCH'])) { $this->method = $method; $this->{$this->method}($_POST);
                } else { $this->method = 'POST';
                } unset($_POST[Config::get('var_method')]);
            } elseif (isset($_SERVER['HTTP_X_HTTP_METHOD_OVERRIDE'])) { $this->method = strtoupper($_SERVER['HTTP_X_HTTP_METHOD_OVERRIDE']);
            } else { $this->method = $this->server('REQUEST_METHOD') ?: 'GET';
            }
        } return $this->method;
    }
