Micropython post error

jarain78

Hello everybody, I have a problem, I'm trying to send a wav file using the "urequests" library, but I can't do it. I use a M5GO (FIRE) and micro-piton returns the following error:

TypeError: object with buffer protocol required

Any one knows how I can solve this?.

This is my code:

    url = "http://server_addres/wav_file"
    fin = wave.open('/sd/temp.wav', 'rb')
    
    file_to_send= {'file': ubinascii.b2a_base64(fin)}
    header={"content-type":"audio/wav", 'file': ubinascii.b2a_base64(fin)}
    
    # data=file_to_send,
    
    try:
        r = urequests.post(url,  headers=header)
        print (r.text)
    finally:
        print("Close...")
        fin.close()

@jarain78 Hello,

I'm currently facing the same pb with my M5dial:

Any idea ?

URL_REFRESH='https://api.netatmo.com/oauth2/token'

    params={
        'grant_type':'refresh_token',
        "client_id":'xxx',
        "client_secret":'xxx',
        "refresh_token":'xxx'
    }

rep=requests.post(URL_REFRESH, data=params)

=> TypeError: object with buffer protocol required
