webman框架1.5版本,需要对请求生命周期中增加全局设置数据和获取怎么做.[已解决]

$request->withAttribute('a', 'b');
public function withAttribute('a', 'b');($name, $value)
    {
        $clone = clone $this;
        $clone->attributes[$name] = $value;
        return $clone;
    }

use support\Context;

Context::set($key, $value);
Context::get($key);
