curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

与“SSL证书问题：无法获取本地颁发者证书”相关的错误。需要注意的是，这适用于发送CURL请求的系统，而不是接收请求的服务器。

从https://curl.haxx.se/ca/cacert.pem下载最新的cacert.pem

将以下行添加到php.ini中：（如果这是共享宿主，并且您没有访问php.ini的权限，那么您可以将其添加到public_html中的.user.ini中）。

默认情况下，FastCGI进程将每300秒解析一次新文件（如果需要，您可以按照https://ss88.uk/blog/fast-cgi-and-user-ini-files-the-new-htaccess/的建议添加几个文件来更改频率）。
