HTTP_GET/HTTP_POST Server.send() results

[wspitts2]

I am trying to switch over some examples to use the AutoConnect Library.

I have a simple form HTML that I would like to do a HTTP_GET or HTTP_POST with and save a form field onto the ESP32 based on a user input. I can use the submit button of the form and the method of POST or GET to call the appropriate Server.on function. However, I am not able to find where the results are returned to parse for either POST or GET methods. It seems logical that these would be available and I must simply be overlooking something:

I do the following and I can get through to the POST or the GET handlers:
Server.on("/wolf", HTTP_POST, handleWolfPost);
Server.on("/wolf", HTTP_GET, handleWolfGet);

so, handleWolfGet() looks something like:

String page = SOME FORM HTML that does a GET method and an action=/wolf on button submit
Server.send(200, "text/html", page);

I then fill out the form, click submit, and it returns to the GET method and has a /wolf?ssid=text in the URL (note, I just call this ssid as the name, but it is just a place holder, this could very easily be foo or something generic that I want to put into the ESP32 to set a flag or something, I fully realize the AutoConnect handles SSIDs and such).

Once I am in the handler, how do I action on the HTTP response from the GET/POST method?

If I use the AsyncWebServer using other examples and not the AutoConnect library I run AsyncWebServerRequest

Server.on("/wolf", HTTP_GET, [](AsyncWebServerRequest *request){
request->send_P(200, "text/html", index_html, processor);
});

Then I can do operations on the request like:
request->getParam("ssid")->value();

I can then use this to write to a SPIFF or do some other meaningful operation.

Well, I am an idiot. I was getting the server.args AFTER I was redoing a Server.send. I have updated the code above to:

// https://techtutorialsx.com/2017/03/26/esp8266-webserver-accessing-the-body-of-a-http-request/
void handleWolfGetResult(){
Serial.println("GET RESULT PAGE");
String message;
message += Server.args();
message += "\n";
for (uint8_t i = 0; i < Server.args(); i++) {
message += " " + Server.argName(i) + ": " + Server.arg(i) + "\n";
}
Serial.println(String(Server.argName(0) + ": " + Server.arg(0)));
Server.send(200, "text/plain", "Success " + message);
}

And it now spits out the args to the serial port and to the webpage.

Server.on("/wolfGetResult", HTTP_GET, handleWolfGetResult);

Also, another issue I was having is that it matters the order of operation of the Server.on functions:

Server.on("/wolf", HTTP_ANY, handleWolf);
is the same as
Server.on("/wolf", handleWolf);
So if I do this:
Server.on("/wolf", handleWolf);
Server.on("/wolf", HTTP_POST, handleWolfPost);
Server.on("/wolf", HTTP_GET, handleWolfGet);

Server.on("/wolf", handleWolf) would always trigger and the HTTP_POST and HTTP_GET variants wouldn't!

So, for proper operation:
Server.on("/wolf", HTTP_POST, handleWolfPost); // HANDLE THIS FIRST
Server.on("/wolf", HTTP_GET, handleWolfGet); // HANDLE THIS SECOND
Server.on("/wolf", HTTP_ANY, handleWolf); // CATCH ALL, HANDLE THIS LAST
