Considerations when PHP initiates HTTPS (SSL) requests using curl

Error when using curl to initiate an HTTPS request: "SSL certificate problem, verify that the 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 that you want to initiate is normal:

Method one, set to No authentication certificate and host.

Before Curl_exec () is executed. SET option

$ch = Curl_init ();

......

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

Method Two, set a correct certificate.

The local SSL discriminant certificate is too old to cause the link error SSL certificate to be incorrect.

We need to download a new SSL local discriminant file

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

Put it in the Program Files directory

Curl adds the following configuration

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

Done
