Unable to POST data

Post by ebolisa » Sun Aug 09, 2020 9:09 pm

Hi,

I'm trying to post data using an ESP32. A similar code shown below works fine when executed from a Raspberry.

I'm getting a response from the server stating that the api key is wrong, but it's not so, I'm sure I've an error in my code.

I appreciate some feedback.

TIA

EDIT:
Solved. My issue was related to the data sent. It should by in String format not dictionary.

Code: Select all

import urequests, ujson, utime

# API key here
API_KEY = '0000'

# defining the url
url = "https://www.mydomain.com/ip_post.php"

myip=wlan.ifconfig()[0]

# data to be sent to api
mydata = {'api_key':API_KEY,
        'board':'2',
        'temp':'23',
        'uptime':'33',
        'ip': myip
        }

def main():
    # sending post request and saving response as response object
    header = {'Content-type': 'application/x-www-form-urlencoded; charset=utf-8'} 
    #header = headers = {'Content-Type': 'multipart/form-data;boundary="boundary"'}
    response=urequests.post(url, data=mydata, headers=header)
    #response = urequests.post(url, data = mydata)
    
    # extracting response text
    url_response = response.text
    print("The response from URL is:%s"%url_response)
    
print(mydata)
    
if __name__ == '__main__':
    try:
        #update()
        print('--- Booted and time set ---')
        while True:
            main()
            gc.collect() #clear memory and display
            utime.sleep(2)
    except SyntaxError as e:
        print(e)
        
Display console:
MPY: soft reboot
my ip: 192.168.0.12
NTP server query successful.
