Using IotWebConf on esp32 with esp_http_server.h already included

[jameszah]

HI, I tried to add IotWebConf to a program that already had esp_http_server installed for http, ftp, WiFiClientSecure, ... and ran into a few problems. I think the WebServer.h for esp32 is a different version of the http services than you get in esp_http_server.h.

Wondering if anyone has tackled this conversion?

Other issues:

1. I see you use the eeprom starting at position 0, which is logical as I was already using that position. In my code I can move it, but a #defne to move it in this library might be nice.

2. Had to dig through the code to figure out this "#" feature, after you have set it up on 192.168.4.1 with your name/password for your wifi router, and the name/password for your esp32 for the next time you try to configure it. It all set up fine at 192.168.4.1, and connected to my router, but then I tried to connect to it again through my router, and my computer connect fine to the esp32, but then it gives this "#" name/password question. Which is not the name/password you just gave it, But the name "admin" and the password you just gave it. You could put that into the example program comments. 😄

I'll update this question, when do the switch from WebServer.h --> esp_http_server.h

Maybe this does it -- just have to figure out how to grab a pull-request:
I don't think it is already there -- I cannot find #define IOTWEBCONF_CONFIG_USE_ASYNC

And this I think is the answer to my question #1

// -- We might want to place the config in the EEPROM in an offset.
#ifndef IOTWEBCONF_CONFIG_START
#define IOTWEBCONF_CONFIG_START 0
#endif

Howdy, made a little progress on this.

First, I discovered how to find a pull request, just follow the fork and its mods to https://github.com/h2zero/IotWebConf/tree/async

But it solves a different problem.

My problem was using the object WebServer defined in WebServer.h and at the same time trying to use the basic esp_http_server.h functions. There is a big feud between the code about who owns the symbol HTTP_GET, which is "1", but the compiler (arduino IDE 1.8.12) cannot resolve the feud. I wrote up my partial solution below, but I still have a problem of the WebServer.h taking control of the network, and preventing the web, ftp, etc functions I was already using to run as before.

So, looking back at my problem here, it is clear that you cannot have two different bits of software running the web.

I was using the esp_http_server.h calls, such as:

httpd_handle_t camera_httpd = NULL;
httpd_start(&camera_httpd, &config), 
httpd_register_uri_handler(camera_httpd, &index_uri), 
httpd_resp_send

And this uses WebServer.h calls such as:

 WebServer server(80);
 server.on("/wifi", []{ iotWebConf.handleConfig(); });
  this->_server->sendHeader("Content-Length", String(message.length()));
  this->_server->send(404, "text/plain", message);

So I could do a big fork and merge all the IotWebConf stuff into the httpd_ style of calls and it could run in parallel with all the other web stuff I have in my program.

So I'll close this. -- not done, but confusion resolved. 😄
