Callback behaviour is buggy (ESP8266)

[dirkvranckaert]

I'm on the latest version of the library.
My scenario: every 10 seconds I want to make a POST call to a server containing a JSON body.

The full testing code is available here: https://gist.github.com/dirkvranckaert/93ca29597a9f6732465d23cb9e2b62b3

Here is the log of what I observe:

11:41:06.936 -> ****************************************
11:41:07.010 -> ****************************************
11:41:07.010 -> ****************************************
11:41:07.087 -> 
11:41:07.087 -> 
11:41:07.087 -> Sending new request...
11:41:07.087 -> Network result... 
11:41:07.125 -> NOT_CONNECTED
11:41:07.125 -> -4
11:41:07.125 -> Network result callback done!
11:41:07.162 -> Network result... 
11:41:07.200 -> HTTP OK
11:41:07.200 -> 200
11:41:07.200 -> Network result callback done!
11:41:17.048 -> 
11:41:17.048 -> 
11:41:17.048 -> ****************************************
11:41:17.085 -> ****************************************
11:41:17.119 -> ****************************************
11:41:17.194 -> 
11:41:17.194 -> 
11:41:17.194 -> Sending new request...
11:41:17.339 -> Network result... 
11:41:17.339 -> Bad Request
11:41:17.378 -> 400
11:41:17.378 -> Network result callback done!
11:41:27.091 -> 

So my observation is:

1. The first network call is executed and reports twice in the callback, first with HTTPCODE_NOT_CONNECTED followed by the regular network response. That seems bizar to me that I first get the not connected followed by a proper response... I'm not sure if that's ok and if I can safely ignore the not connected...
2. Then we fire the second network call (same call just 10 minutes after), that call is started with success, however it immediately reports back with an HTTP error code 400 (I check my server and the request never arrived so it's definitely a client thing).

This sequence keeps repeating itself exactly like this, calls 3, 5, 7,... are like call 1. The followup calls 4, 6,, 8,... are always like call 2!

In my opinion both are an issue.

Can you please have a look?

Need to mention for testing that I created a simple PHP server with an empty index.php in it. That script I served with php -S localhost:3000 from my computer and then used ngrok to give me an HTTP link to it.

I've investigated this some more from my side and it appears that every 2nd, 4th,... request (so after a 'good' request) no headers are being sent. My server shows me now that the Host is missing, the User-Agent is missing,...

HI @dirkvranckaert

Please try the new AsyncHTTPRequest_Generic v1.10.1. Your contribution is noted in Contributions and Thanks

---

Releases v1.10.1

1. Fix bug of wrong reqStates. Check Release 1.9 breakes previously running code #39 and Callback behaviour is buggy (ESP8266) #43
2. Optional larger DEFAULT_RX_TIMEOUT from default 3s, for slower networks

[dirkvranckaert]

Great, I'll give it a try one of these days! Thank you for the quick update! Much appreciated!
