Now Phalcon handle and get data from request via URI and native Phalcon\Http\Request.
I want to use RoadRunner in my application, but RoadRunner provide request as Psr ServerRequest.
Therefore I cant 't use RoadRunner in my Phalcon 4 application.
Sure, I can to write my realization of Phalcon\Http\RequestInterface for get data from Psr ServerRequest, but it so many code and i want to see this realization from Phalcon Developers.
Thank.
As I can see, they do integrations to frameworks by them self:

Also here, work in progress for Laravel - https://github.com/spiral/roadrunner/issues/96
And here about phalcon - https://github.com/spiral/roadrunner/issues/153
v4 does have the PSR related components in the Http\Message namespace. You can use them directly from there.
In future versions the goal is to rewrite the full HTTP layer so that it only uses PSR classes. That will probably not happen until 4.2 maybe later.
Thank you, @niden
I will be waiting for 4.2)
We do not do integrations by ourselves... that will be too much. You can also use underlying Http consumer to skip psr-7 step if needed.
I write a simple adapt, you canrefer to the implementation.
