I’m trying to pass get variables through an HTTPS url to generate xml code and parse the xml to grab an element’s attribute (total_charge) value and turn that into a php variable called $shippingcost. I have the following code and I’m getting the following error. (I have the file names as .pem but I just changed the file extensions of the actual ssl and rsa key files as they had .cabundle extensions for some reason. So I’m not sure if I did that right.)
$xml = ' weight_system="IMPERIAL" shipper_number="000222000" destination_postal_code="'.$data5['zip'].'" service_type="1" '; $xml2 = ' total_pieces="'.$value.'" total_weight="'.$weight.'" '; $token = 'token_here'; $base_url = 'https://www.shipping_company_website.com/XML/RatingXML.jsp'; $request_url = $base_url . '?' . http_build_query(array( 'shipment' => '<shipment ' . $xml . '><total ' . $xml2 . '/></shipment>', 'token' => $token )); // Get cURL resource $curl = curl_init(); // Set some options - we are passing in a useragent too here curl_setopt($curl, CURLOPT_URL, $request_url); curl_setopt($curl, CURLOPT_VERBOSE, 1); curl_setopt($curl, CURLOPT_RETURNTRANSFER,1); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 1); curl_setopt($curl, CURLOPT_CAINFO, '/home/username/ssl/certs/ca.crt'); curl_setopt($curl, CURLOPT_SSLCERT, '/home/username/ssl/certs/cert.pem'); curl_setopt($curl, CURLOPT_SSLCERTPASSWD, 'password_here'); curl_setopt($curl, CURLOPT_SSLKEY, '/home/username/ssl/certs/key.pem'); curl_setopt($curl, CURLOPT_SSLKEYPASSWD, 'password_here'); // Send the request & save response to $result $result = curl_exec($curl); echo curl_error($curl); // Close request to clear up some resources curl_close($curl);
SSL certificate problem: self signed certificate in certificate chain
Here is an example of what the xml code would look like when generated. I got this example by entering test get variables into the url and pasting the url in the browser url bar.

Under the php.ini file I added the following,
extension = php_curl.dll
allow_url_fopen = On
I have an RSA key, SSL cert, CA cert and one password. I have no clue how to find out how to fix this error because I don’t know what’s causing it. I was searching on Google and I came across some posts about concatenating the rsa key, ssl cert and ca cert chained into one file and convert it to .pem and doing all this in the curl command line. However, I don’t know where the curl command line is, should it be under my hosting account somewhere? I have a shared LINUX hosting account and I’m not sure which icon to click from cPanel to open this curl command line to enter commands. How would I then convert the file to .pem? Can I just change the extension of the file to .pem? If all the certs are concatenated on one file then do I need these lines, CURLOPT_CAINFO, CURLOPT_SSLCERT, CURLOPT_SSLCERTPASSWD?
Does the curl code on the php page above need to be present if I have access to the curl command line from my hosting account and start entering commands in there or are both commands and the code above needed together to make what I’m trying to do work. Also alot of people were mentioning libcurl, Where do I find that in my hosting account.
Is there a definitive answer to the error I’m getting shown above, I don’t really understand what it means and where the problem is. If there is something wrong that I’m doing in my code, please let me know as well. Thanks!
