curl command to ssl handshake and https posts

[k1447321]

hey there,

I would like to transform a curl request to a qt method curl command looks like this:

curl --cacert cacert.pem --request 'POST' 'https://api.twitter.com/1.1/statuses/update.json' --data 'status=ekmek' --header 'Authorization: OAuth oauth_consumer_key="ir0j0XHEZAjl5OIMLvRtGDpvz", oauth_nonce="d0d616f462d9d3dd5bb39b23b2ae76ea", oauth_signature="2IAkMds2Pxtp699MReoyupgfZl8%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1441658718", oauth_token="3427524377-klG6CAjAWyWOo9eR7g6WtRm8nGoo9CtQHSX3jpC", oauth_version="1.0"' --verbose

curl --cacert cacert.pem --request 'POST' 'https://api.twitter.com/1.1/statuses/update.json' --data 'status=ekmek' --header 'Authorization: OAuth oauth_consumer_key="ir0j0XHEZAjl5OIMLvRtGDpvz", oauth_nonce="d0d616f462d9d3dd5bb39b23b2ae76ea", oauth_signature="2IAkMds2Pxtp699MReoyupgfZl8%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1441658718", oauth_token="3427524377-klG6CAjAWyWOo9eR7g6WtRm8nGoo9CtQHSX3jpC", oauth_version="1.0"' --verbose

To copy to clipboard, switch view to plain text mode 

so I want to have a ssl handshake using my cacert.pem and send my request with a body and a custom header.

thanks in advance

To copy to clipboard, switch view to plain text mode 

Connects to Twiteer but fails:

void Fetch::finished() "{"errors":[{"code":32,"message":"Could not authenticate you."}]}"

void Fetch::finished() "{"errors":[{"code":32,"message":"Could not authenticate you."}]}"

To copy to clipboard, switch view to plain text mode 

so it clearly connected to Twitter without SSL errors.
