Error: "Can't find nonce in www-auth" -cause regex defined not correctly #12

Open Carsak opened 1 year ago

I cant auth to sip server, cause class PhpSip cant parse "nonce"

in code we have line line if (!preg_match('/^WWW-Authenticate: .* nonce="(.*)"/imU',$this->rx_msg, $m))

But I got this string in rx_msg 

SIP/2.0 401 Unauthorized
Via: SIP/2.0/UDP 192.168.56.1:52619;rport=52619;received=192.168.56.1;branch=z9hG4bK400475

Server: Asterisk PBX 20.1.0
Content-Length:  0

So the regexp pattern must be /.*WWW-Authenticate: .* nonce="(.*)"/imU not /^WWW-Authenticate: .* nonce="(.*)"/imU

I cant figure out, why I got error if regexp is correct. I checked this on regexOnline it is correct: image

But in php i got error: image

the text is same

Is the spaces in the expression. Remove spaces!

if (!preg_match('/^WWW-Authenti*cate*:.n*once="(.*)"/miU',$x, $m)) {

OMG. yes. So, correct pattern should be /^WWW-Authenticate:.*nonce="(.*)"/imU not /^WWW-Authenticate: .* nonce="(.*)"/imU
