Porting Old Mojolicious Code to Current Version

[ornh]

Hi,
I am having issues trying to resurrect some old (Mojolicious version 4) code burrowed from the internet. Following are the errors I am getting:

Mojo::Reactor::EV: I/O watcher failed: Can't locate object method "is_writing" via package "Mojo::Transaction::HTTP"

Mojo::Reactor::EV: Timer failed: Can't locate object method "server_close" via package "Mojo::Transaction::HTTP"

I have been through the change log and looked at upgrading notes here: https://github.com/mojolicious/mojo/wiki/Upgrading. I see the methods have changed but there is nothing stating how these calls should be made in the latest version of Mojolicious.

Can someone please lend a hand?

Thanks

That's a very low level API pretty much nobody ever used. And it's been a very long time since it has been removed. So, i doubt you'll be able to find anyone who still remembers how it worked i'm afraid. Your best bet is probably to look up the version in Changes and then study the commits.

It seems very old indeed. Perhaps, rather than trying to revive the old code, you could point me in a better direction. I am trying to implement an intercepting proxy using Mojolicious. I need to be able to pause and modify requests/responses on the fly. One example would be updating Bearer tokens in request headers. I see examples of a standard HTTP proxy and a Reverse proxy but nothing for an intercepting proxy. Any suggestions?

That's a built-in feature now. https://docs.mojolicious.org/Mojolicious/Plugin/DefaultHelpers#proxy-start_p

Thank you for the link. However, this seems to be for building out requests by hand. How would I accept requests from a browser, modify the request, send the request to the server and then send the response to the browser?

Considering that there's also a very high chance that those methods have been used wrong (they are not really something a Mojolicious app would use), maybe you might even be better off just trying to fix the code.

Hi kraih,
After a good bit of searching, I finally found the examples page and the connect-proxy example of yours https://github.com/mojolicious/mojo/blob/main/examples/connect-proxy.pl. This looks to be very close to what I need. I can see that $buffer has the full request and can be manipulated prior to the request being sent. However, I don't see any response headers, only the body returned in $chunk. Is there a way this code could be modified to use Mojo::UserAgent and parse the requests/responses? Or at least get to the response headers in the current code. Sorry if this is a very noob question, I am fairly new to OOP and this is my first time using Mojo.

Your help is greatly appreciated,
Thank you
