Unable to enable crypto on TCP connection api.mysite.com on Zend - zend-framework2

Question

I was creating a module application for Zend Framework 2. When I try to send a post request to my server with the necessary details, I get the error "Unable to enable crypto on TCP connection api.mysite.com".
Earlier, I was getting the error "Unable to enable crypto on TCP connection api.mysite.com: make sure the "sslcafile" or "sslcapath" option are properly set for the environment."
On googling, I found I should set sslverifypeer to false. After doing this, I was left with the 1st part of the sentence "Unable to enable crypto on TCP connection api.mysite.com."
Not getting idea where I could be wrong.
Under previous exceptions, I get "stream_socket_enable_crypto(): this stream does not support SSL/crypto"

Answer 1

Please see this note in the docs: http://framework.zend.com/manual/2.3/en/modules/zend.http.client.html#connecting-to-ssl-urls . You shouldn't set sslverifypeer unless the site you're connecting to doesn't have a valid SSL certificate. Instead, set sslcapath as the error suggests. This gives PHP a way of validating the SSL certificate supplied by the host you're connecting to.

Answer 2

This is due to your site trying to communicate with a ssl used site. If you want to use default adapterZend\Http\Client\Adapter\Socket you have to define sslcapath configuration option in order to allow PHP to validate the SSL certificate.
To avoid this I used the curl adapter instead.
$client = new Client();
$client->setUri($endPointUrl);
$options = array('put your options');
$client->setOptions($options);
$client->setAdapter('Zend\Http\Client\Adapter\Curl');
$response = $client->send();

You need to set Http Client Options.
Here is the working setting:
// eko/FeedBundle and issue with ssl site -> https://github.com/eko/FeedBundle/issues/51
$httpClientOptions = array(
'adapter' => 'Zend\Http\Client\Adapter\Socket',
'persistent' => false,
'sslverifypeer' => false,
'sslallowselfsigned' => false,
'sslusecontext' => false,
'ssl' => array(
'verify_peer' => false,
'allow_self_signed' => true,
'capture_peer_cert' => true,
),
'useragent' => 'Feed Reader',
);
ZendFeedReader::setHttpClient(new ZendHttpClient(null, $httpClientOptions));
Here is the NOT working setting:
// eko/FeedBundle and issue with ssl site -> https://github.com/eko/FeedBundle/issues/51
$httpClientOptions = array(
'adapter' => 'Zend\Http\Client\Adapter\Socket',
'persistent' => false,
'sslverifypeer' => false,
'sslallowselfsigned' => true,
'sslusecontext' => true,
'ssl' => array(
'verify_peer' => false,
'allow_self_signed' => true,
'capture_peer_cert' => true,
),
'useragent' => 'Feed Reader',
);
ZendFeedReader::setHttpClient(new ZendHttpClient(null, $httpClientOptions));
Note: I have issue with symfony bundle eko/feedBundle that use Zend library so essentially it is the same for you.
this solution tested and proven to be working.
