A colleague today reflected that an error was reported when using curl to initiate an HTTPS request: "SSL certificate problem, verify that CA cert is OK." Details:error:14090086:ssl routines:SSL3_GET_SERVER_CERTIFICATE:certificate Verify Failed "

Obviously, there was a problem validating the certificate.

There are 2 ways to use curl if the HTTPS request you want to initiate is normal:

Method one, set to not verify the certificate and host.

Before executing curl_exec (). SET option

Copy Code code as follows:

$ch = Curl_init ();

......

curl_setopt ($ch, Curlopt_ssl_verifypeer, FALSE);
curl_setopt ($ch, Curlopt_ssl_verifyhost, FALSE);

Method Two, set up a correct certificate.

The local SSL discriminant certificate is too old, causing the link to error the SSL certificate is incorrect.

We need to download a new SSL local discriminant file

Http://curl.haxx.se/ca/cacert.pem

Put it in the program file directory

Curl Add the following configuration

Copy Code code as follows:

curl_setopt ($ch, curlopt_ssl_verifypeer,true);
curl_setopt ($ch, Curlopt_cainfo,dirname (__file__). /cacert.pem ');

Done

(I have failed to verify ...) The error message is: SSL certificate problem, verify this CA cert is OK. Details:error:14090086:ssl routines:SSL3_GET_SERVER_CERTIFICATE:certificate Verify failed)
