执行FQL时出现SSL证书问题

Question

I am trying to execute the following FQL statement:

SELECT first_name FROM user WHERE uid = '[logged in user's uid]'

Here is my PHP code:

$facebook = new Facebook(array(
    'appId' => [my appId],
    'secret' => [my secret]
));

$query = "SELECT first_name FROM user WHERE uid = '$uid'";
$data = $facebook->api(array('method' => 'fql.query', 'query' => $query));

I am getting the following error:

Exception: SSL certificate problem, verify that the CA cert is OK.
Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:
certificate verify failed

I am using the latest Facebook PHP API, and the file fb_ca_chain_bundle.crt is present in the same directory as facebook.php and base_facebook.php. I am running this on WAMP (Windows, Apache, MySQL and PHP).

I would greatly appreciate your help.

Thank you,

Export the certificate from your browser and import it in your JVM truststore (to establish a chain of trust):

<JAVA_HOME>\bin\keytool -import -v -trustcacerts
-alias server-alias -file server.cer
-keystore cacerts.jks -keypass changeit
-storepass changeit
