Description

I´m looking for someone, who is willing to help me with adding ESPAsyncWebserver via #define in sketch like btomer did few years back. I did some work on this in my fork, but so far I can not compile sketch with this define.

[tablatronix]

Ill take a look and add a branch, might be a few days

Hi, may be this is a good start point or a good excuse to "join" both projects:

https://github.com/khoih-prog/ESP_WiFiManager

May be all collaborators of both projects could collaborate like a team in only one project, not to have to roads for the same finish.

[tablatronix]

The async library is mostly compatible with the regualar one, so there is not much to do to add it, just some testing

[bigFin]

BUMP!

[tablatronix]

I am actually using it right now to see what we need to do

[fkoteam]

I am actually using it right now to see what we need to do

is it uploaded? what version should I use?

Thank you very much for your work!

[tablatronix]

Good news, it should work and be doable Bad news, its alot of work, lots of refactoring, almost everything that uses the server needs to be changed. I will start working on it a little bit and see , the problem is most of the arg and header stuff doe not work the same and has to be rewritten, even stopping the server is different syntax.

[dronecz]

Awesome, can we help somehow?

[tablatronix]

I need to figure out what needs to change for the new ota upload, and to find the new syntax to get args. I pushed a new branch, it is in progress, as far as I got atm. But its a start and you can see the changes in handleroot for sending headers now, I was going to make it the same codebase and swappable, but it is too much work atmm easier to just change it all, another 4-5 hours plus testing and it should be done

[tablatronix]

Its done, ready to test, there are a few things that might be broken, ota uploading has to be rewritten , esp32 not worked on yet, and url params not added back in for no scan and refresh

[tablatronix]

Have you tried this yet?

[dronecz]

Hi, sorry for delay, I had no time to try it until now. I implemented in my code and it works. I was able to connect to my AP via WM without problem.

Many thanks for this.

Is there something specific which you want me to test?

[tablatronix]

There are some gotchas that I need to continue to work on, but It should work ok. Just that it works, you can save, change reset, use params whatever you were doing before.

[dronecz]

Hi, sorry for long delay but I finally have time to make more work on my project with WM using ESPAsyncWebserver.

I tried OnDemandConfigPortal sketch and with async library does not scan and show networks. To confirm this I tried same sketch with latest alpha release and that one is working as it should.

Thanks for help.

@tablatronix any hint on this one? I looked on this again and difference is somewhere in autoConnect() function. If I comment out call to this function and start configportal manually by pressing button, I do not see any networks. Also value of _lastscan variable is not reset when reach 60 seconds.

[tablatronix]

I merged master back into this and resolved conflicts, ota seems all jacked up, code needs to be updated.

Backport the following methods to abstact master to prepare for cross compile..

• [ ] setupHTTPServer

• [ ] teardownHTTPServer

• [ ] setupDNSD

• [ ] HTTPSend

• [ ] template all web handlers with arguments to allow both or other webservers objects or globals

• [ ] fix ota code

[tablatronix]

My idea was to make WM compatible with both or any webserver, but I have no idea how to get this working ideally.

I want to keep route callbacks as seperate methods, which means lots of functions to deal with. therefore I want to avoid having to have overloads for these callbacks..

My idea was to use a template to have either local server pointer or async resp obj as the first argument. Now i dont want to pass the local pointer all the way through the webserver binds thats just asking for problems, and the syntax structures might be different. so instead i want to pass an empty arg for this, I want to also avoid adding variadic args to avoid the overhead etc as we do not really need it.

I also do not want to refactor the entire web handling into some abstract class or something more complex.

Idea is like

template <typename T>
void          callbacknofmany(T *obj, bool argx);



std::unique_ptr<choiceserver> server;

server->on("", HTTP_ANY, std::bind(&myclass::callbacknofmany, this, null , true)); // sync - global or server pointer
server->on("", HTTP_ANY, std::bind(&myclass::callbacknofmany, this, std::placeholders::_1, true)); // async  - local response obj


template <typename T>
void myClass::callbacknofmany(T *serverobj, bool argx) {
    if(serverobj) serverobj->sendresponse();
    else server->sendresponse()
}

I just am not sure if this is the best route, or how to properly do the templates, nullptr has issues, so just going with something empty and adding a check in the callbacks seems easier

[lucaoliano]

Hi @tablatronix, on my fork I have an implementation that supports both WebServer and AsyncWebServer. Can you take a look at it? If you think it would be good, I'm happy to contribute with a PR.

[tablatronix]

Thanks, I was hoping to find a way to do it much cleaner than having all those blocks, makes maintenance a nightmare and code legibility is a mess
