使Guzzle信任自签名证书？

Question

With Guzzle HTTP client I know you can set new GuzzleClient(['verify' => false]) to have it not check the certificate, eg. when you are using a self-signed certificate. But how can I make it accept and trust a specific self-signed certificate, so that you don't just open up for ANY certificate but only one specific one - is that possible?

Answer 1

A self-signed certificate is its own authority, so simply set the verify option to the filename of the certificate:

// Use a custom SSL certificate on disk.
new GuzzleClient(['verify' => '/path/to/self-signed/cert.pem']);
