php curl 2 ways to get https requests, curlhttps

Today a colleague reported that when using curl to initiate an https request, an error was reported: "SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed”

Obviously, something went wrong while verifying the certificate.

If you want to use curl to initiate a normal https request, there are two ways:

Method 1: Set not to verify the certificate and host.

Before executing curl_exec(). Set option
Copy code The code is as follows:
$ch = curl_init();

......

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

Method 2: Set a correct certificate.

The local SSL certificate is too old, causing the link to report an incorrect SSL certificate.

We need to download the new ssl local identification file

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

Put it in the program file directory

curl adds the following configuration
Copy code The code is as follows:
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,true); ;
curl_setopt($ch,CURLOPT_CAINFO,dirname(__FILE__).'/cacert.pem');

Done

(My verification failed... The error message is: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed)
