re.search Q

[buran]

I am not sure how you come up with this string (and I suspect there is flaw in your approach), but

from urllib.parse import parse_qs
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'
print(parse_qs(request.splitlines()[-1]))

output

Output:
{'ssid': ['my_ssid'], 'password': ['my_pass'], 'ip': ['192.168.1.222'], 'gw': ['192.168.1.1'], 'sbnet': ['255.255.255.0'], 'dns': ['8.8.8.8']}
