ESP8266HttpClient | Small Arduino library to manage ESP8266

I have developed a password verification system using Arduino Nano+ESP8266 (FrontEnd) and Backend with Flask REST API server.

Following is my code of ESP8266, Which is passing the HTTP POST request to REST API server,

I cannot not find a solution for this problem. Everything worked very well when I tried a month ago, but now, when I launch it, it does not work anymore. The problem occurs when I send http.POST(data); request to the given address, but Serial.println(httpResponseCode); returns -11. I've tested my domain URL on Postman and everything worked there. Thank you for any help.

I have a flask application that I need to communicate with my ESP8266 and I'm failing miserably to achieve that. It's not supposed to be hard, but I'm clearly missing something, and I wouldn't be surprised since is my first time working with flask. Let me try to explain what I've done so far.

This is my flask code:

Why I am unable to send get request. It always response 400.The URL are okay there is no problem in it. Actually I need to send data using get request. I have tried my best to find the solution but I didn't get any idea about it. Please anyone can help me with the code

I have written a code for my Arduino to read data from sensor and then post to a PHP file called post-data.php, which then the PHP will insert the data into a database. However, my Arduino does not seemed to be able to post the data or it is not posting it correctly.

I'm trying to send a temperature reading to a php file in my website. However, the temperature variable doesn't seem to be passed. Below I use the following Arduino code:

I am trying to set up an ESP8266 ESP-01 WiFi Module to post a tweet when sent some sensor data. For now, I'm just testing out the POST > Webhooks > IFTTT > Twitter workflow.

I get a response code of -1 (negative one) in the serial monitor when I run the below code. A few notes:

• I am using a USB programmer that the ESP-01 plugs in to to do all this (called ESP-01S USB to ESP8266 ESP-01S Wireless Wifi Adapter Module Wi-Fi CH340G 4.5-5.5V, 115200 Baud Rate, if you wanna see the specific one), so not running the ESP-01 through like an arduino uno or anything, if that somehow matters
• I know the sketch upload is working and the script is running fine, as the ESP-01 reports its connection to my network and my Wifi network reports a connection to the device
• I know the trigger url works because it posts the tweet when I run it from within IFTTT Webhooks service and when I "curl" it from terminal
• I tried to use GET instead, but it had its own issues, plus I am going to want to send sensor values, so want POST to work
• I've tried both the urlencoded and json versions below, same result. Would prefer the uncommented json version, as am familiar with that
• I am a total POST beginner, so am probably missing something stupid
• It says timerDelay is 10 seconds but is set to 20. That's because I thought maybe the POST was just timing out? So I gave it more time
• I also rolled back the ESP8266 library on Arduino IDE, per some Arduino forum rec. No help.
• I tried flashing the ESP-01 with NodeMCU one time, didn't do anything. But not sure if that has to be done before every new sketch upload?

Here's my code. The trigger is real, so feel free to put in your own SECRET_KEY and post the app. Posts to @KreiderPlants on Twitter.

I want my NodeMCU V3 to fetch weather data from OpenWeatherMapApi. I found some sample codes how to send GET request, but the response is getting cut randomly. After reading response, I print the length of the received JSON response. The response should have something about 16k characters, but it's random every request. Sometimes it's 16k as it should be, sometimes 11k, sometimes 13k etc. This is my code:

Hi I'm new to Django framework and I am on a project on which to send http.POST data from NodeMCU to the web application using the Django Framework and the sent data is a string ID of the RFID card.

I want to render the POST data sent by the NodeMCU to the textarea in the template below. I dont know how to handle http.POST sent by the NodeMCU using the Django Framework.

I tested the views functions and it rendered data to the templates. I don't if the data is successfully sent or received.

Arduino version 1.8.13

Django version 3.1.4

Any help would be appreciated
