re.search Q

[ebolisa]

I suggest this ersatz

>>> {m.group(1): m.group(2) for m in re.finditer(r'([a-z]+)\=([^=&\n]*)', request)}
{'q': '0.9\r', 'ssid': 'my_ssid', 'password': 'my_pass', 'token': '', 'ip': '192.168.1.222', 'gw': '192.168.1.1', 'sbnet': '255.255.255.0', 'dns': '8.8.8.8'}

Thanks but I cannot use this syntax as I'm using Micropython. Anyhow, I need to list the groups as in my prior post.

Then you have to prevent the capture group from matching beyond the field by excluding '&'.

import re
request = 'POST /configure HTTP/1.1\r\nHost: 192.168.4.1\r\nOrigin: http://192.168.4.1\r\nContent-Type: application/x-www-form-urlencoded\r\nAccept-Encoding: gzip, deflate\r\nConnection: keep-alive\r\nUpgrade-Insecure-Requests: 1\r\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\nUser-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 15_1_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.1 Mobile/15E148 Safari/604.1\r\nReferer: http://192.168.4.1/\r\nContent-Length: 108\r\nAccept-Language: en-GB,en;q=0.9\r\n\r\nssid=my_ssid&password=my_pass&token=&ip=192.168.1.222&gw=192.168.1.1&sbnet=255.255.255.0&dns=8.8.8.8'

fields = ["ssid", "password", "token", "ip", "gw", "sbnet", "dns"]
regex = "\&.*".join(f"{x}=([^&]*)" for x in fields)

match = re.search(regex, request)
print(match.group(1))
print(match.group(2))
print(match.group(3))
print(match.group(4))

Output:
my_ssid
my_pass

192.168.1.222

Thank you all. Actually the code shown in my first post is correct, there's an error in the string received from the URL which had the variables in the wrong order. So, once fixed that, the code works fine.

import re

request = '...q=0.9\r\n\r\nssid=my_ssid&password=my_pass&token=abcdef&ip=192.168.1.222&sbnet=255.255.255.0&gw=192.168.1.1&dns=8.8.8.8'
match = re.search("ssid=([^&]*)&password=(.*)&token=(.*)&ip=(.*)&sbnet=(.*)&gw=(.*)&dns=(.*)", request)

for _ in range(1, 8):
    print(match.group(_)) 

Output:
my_ssid
my_pass
abcdef
192.168.1.222
255.255.255.0
192.168.1.1
8.8.8.8
