Answer 1

I finally found the reason，its becuse of the library can't find a CA bundle on your system. PHP >= v5.6 automatically sets verify_peer to true by default. However, not all systems have a known CA bundle on disk .

You can try one of these procedures:

1.If you have a CA file on your system, set openssl.cafile or curl.cainfo in your php.ini to the path of your CA file.

2.Manually specify your SSL CA file location

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);  
curl_setopt($cHandler, CURLOPT_CAINFO, $path-of-your-ca-file);

3.disabled verify_peer

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
