cURL error 60: SSL certificate problem: unable to get local issuer

How to resolve ?? ?

To resolve the error, you need to define your CURL certificate authority information path

To do that,

1. Download the latest curl recognized certificates here: https://curl.haxx.se/ca/cacert.pem
2. Save the cacert.pem file in a reachable destination.
3. Then, in your php.ini file, scroll down to where you find [curl].
4. You should see the CURLOPT_CAINFO option commented out. Uncomment and point it to the cacert.pem file. You should have a line like this:

curl.cainfo = “certificate path\cacert.pem” 

这里的路径要配置成绝对路径，不然就报curll77 error

保存重启服务器 Save and close your php.ini. Restart your webserver and try your request again. 

If you do not set the right location, you will get a CURL 77 error.
