Error posting data to my server

[ecabanas]

Hi

I'm using this code to post a json to my server. In Arduino we use HTTP client using this variables:

char server[] = "********.com";
char path[] = "/api/v2/gprs";
int port = 11880;

In the request library I changed the default port 80 in HTTP to 11880
urequest.py

def request(method, url, data=None, json=None, headers={}, stream=None):
    try:
        proto, dummy, host, path = url.split("/", 3)
    except ValueError:
        proto, dummy, host = url.split("/", 2)
        path = ""
    if proto == "http:":
        port = 11880
    elif proto == "https:":
        import ussl
        port = 443
    else:
        raise ValueError("Unsupported protocol: " + proto)

main.py

import os
import pycom
import machine
import time
import ujson
import urequests
from network import WLAN
wlan = WLAN(mode=WLAN.STA)
# Configure first UART bus to see the communication on the pc
uart = machine.UART(0, 115200)

# Configure second UART bus on pins P3(TX1) and P4(RX1)
uart1 = UART(1, baudrate=115200) # 9600 baudrate also causes the same problem
# Init WLAN
try:
  wlan.connect(ssid="******", auth=(WLAN.WPA2, "*********"))
  while not wlan.isconnected():
    time.sleep_ms(50)
    print(wlan.ifconfig())

  print("WLAN connection on ...")
except:
  print("[WLAN] try() (except). reset board.")

data_set = {"dot":"gsm001","data":{"5":0,"6":999,"7":0,"14":3.0832,"31":0,"32":0,"33":0,"35":22,"38":300,"39":-50,"40":300,"42":300}}
jsondump= ujson.dumps(data_set)
urequests.request("POST","http://********.com/api/v2/gprs",data = jsondum, None, {"Content-Type": "application/json"},None).text

but I got the following error:

WiFi connection established
MQTT ERROR! function got multiple values for argument 'user'
ERROR! Could not connect to Pybytes!
Pybytes configuration read from /flash/pybytes_config.json
Traceback (most recent call last):
  File "main.py", line 27, in <module>
SyntaxError: non-keyword arg after keyword arg
Pycom MicroPython 1.20.2.r2 [v1.11-3a7776d] on 2020-11-23; GPy with ESP32

Any idea what I'm doing wrong? I'm a newbie in pycom code, sorry

thank's

@ecabanas If you don't use Pybytes you probably want to disable it with pycom.pybytes_on_boot(False) to avoid confusing messages.

The issue is that you have a mix of arguments with explicit names (name =) and without in your call to urequests.request.

Either use names for all args (method="POST", url="...", data=jsondum, json=None, headers={"Content-Type": "application/json"}, stream=None — in which case you can actually skip those where your argument matches the default) or don't use any and just respect the order (i.e. just remove data=).

Hi @jcaron
WOW!!! thanks now is working perfect!!!

Thanks again!!!
