I was doing a code for sending mails with the playbook and marmalade, this is my code
curl_easy_setopt(curl, CURLOPT_URL, "smtp://smtp.gmail.com:587");
//curl_easy_setopt(curl, CURLOPT_PORT, this->_PORT);
curl_easy_setopt(curl,CURLOPT_CONNECTTIMEOUT, 15);
curl_easy_setopt(curl,CURLOPT_TIMEOUT, 30);
curl_easy_setopt(curl, CURLOPT_USE_SSL, (long)CURLUSESSL_ALL);
curl_easy_setopt(curl, CURLOPT_USERNAME, "xxxxxxx#gmail.com");
curl_easy_setopt(curl, CURLOPT_PASSWORD, "xxxxxxx");
curl_easy_setopt(curl, CURLOPT_MAIL_FROM, this->_FROM);
recipients = curl_slist_append(recipients, this->_TO);
curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, recipients);
curl_easy_setopt(curl, CURLOPT_READFUNCTION, payload_source);
curl_easy_setopt(curl, CURLOPT_READDATA, &upload_ctx);
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
res = curl_easy_perform(curl);
It is the example from libcurl. (http://curl.haxx.se/libcurl/c/smtp-tls.html)
But everytime the curl_easy_perform executes i got the error CURLE_COULDNT_RESOLVE_HOST with every single address it does'nt matter if it is http,smtp, ftp, etc.
And if I put the IP instead of the name i always get Permission Denied.
I thing the error is the fake-ares.cpp and its asynchronous resolve.
I am using libcurl 7.21.7 and Marmalade 6.1
Can anyone help me? :/ or is there another way to send mail?
Thanks

This is my libcurl code. I am trying to send email to my own email domain in linux.
This is my sample libcurl code.
curl_easy_setopt(curl, CURLOPT_USERNAME, "username#mydomain.com");
curl_easy_setopt(curl, CURLOPT_PASSWORD, "mypassword");
curl_easy_setopt(curl, CURLOPT_URL, "smtp://mail.mydomain.com:25");
curl_easy_setopt(curl, CURLOPT_USE_SSL, (long)CURLUSESSL_ALL);
curl_easy_setopt(curl, CURLOPT_MAIL_FROM, FROM);
recipients = curl_slist_append(recipients, TO);
curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, recipients);
curl_easy_setopt(curl, CURLOPT_INFILESIZE, file_size);
curl_easy_setopt(curl, CURLOPT_READFUNCTION, fileBuf_source);
curl_easy_setopt(curl, CURLOPT_READDATA, &file_upload_ctx);
curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L); //Dont display Curl Connection data Change 1L to 0
res = curl_easy_perform(curl);
When I run this code, I am getting the below error.
* Rebuilt URL to: smtp://mail.mydomain.com:25/

Your issue is that your server is providing a self-signed certificate so curl is not able to verify its provenance. You have several options:
The best option is to get a server certificate that is signed by a well-known certificate authority. Some CAs will issue a certificate you can use for free; search for "free ssl certificate". You will need to be able to provide some proof that you control the domain.
You can install your self-signed certificate to the list of trusted CAs on the computer(s) that run your libcurl code. The procedure to do this depends on your OS (even different distributions of Linux may do this differently). This link is a decent starting point for Linux.
Your program can tell libcurl to verify with the self-signed certificate. See Adding self-signed SSL certificate for libcurl.
You can create your own certificate authority and use either of the previous two approaches. The advantage of this over self-signing is it decouples the signing and the signed certificates. If you want to change the server certificate (e.g. if it expires or the host name changes) you don't necessarily need to reconfigure all the clients.
For completeness, you could disable verification by setting CURLOPT_SSL_VERIFYPEER to 0. This is highly discouraged, however, as it makes the access insecure. You should only do this for testing purposes, or in the rare case that the network between client and server is guaranteed to be secure.
I've been working with neteller rest api and I came across an issue.
I am receiving this response: { "error": "invalid_client" }
My code is
$username = '**********';
$password = '*********************************';
$curl = curl_init();
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_URL, "https://test.api.neteller.com/v1/oauth2/token?grant_type=client_credentials");
curl_setopt($curl, CURLOPT_USERPWD, "$username:$password");
curl_setopt($curl, CURLOPT_HTTPHEADER, array("Content-Type:application/json", "Cache-Control:no-cache"));
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$serverOutput = curl_exec($curl);
echo $serverOutput;
The documentation says:
Client authentication failed (e.g., unknown client, no client authentication included, or
unsupported authentication method). The authorization server MAY return an HTTP 401
(Unauthorized) status code to indicate which HTTP authentication schemes are
supported. If the client attempted to authenticate via the "Authorization" request header
field, the authorization server MUST respond with an HTTP 401 (Unauthorized) status
code and include the "WWW-Authenticate" response header field matching the
authentication scheme used by the client.
But I'm not sure I completely understand this..
I've tried every possible solution that I found online, but nothing works.. Is there something wrong with my CURL?
Thanks for your time.
You get this error message if your IP is blocked. Log in to the Neteller TEST merchant site (test.merchant.neteller.com). You will need to email support to get a user if you haven't already. Go to Developer / API Settings and check that the APIs are enabled and that your IPs are added.
You need to do the same thing for production (merchant.neteller.com).
It might be a header issue.
Try this as your content type:
application/x-www-form-urlencoded
This should probably solve it:
$data = array("scope" => "default");
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
I am using curl to verify the PayPal IPN but it throws error: SSL certificate problem: unable to get local issuer certificate. The same code is working on development server and when I moved to client server it is not working.
DO I need to purchase ssl certification in order to make payment via PayPal express checkout or any change in my coding part or any setting need to make on server.Curl is already enabled on server. Any help will be appreciated.
My code below, and its a reduced test page for this:
$req = HAVING PARAMETERS FROM PAYPAL;
$ch = curl_init("https://www.sandbox.paypal.com/cgi-bin/webscr");
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
curl_exec($ch);
if(curl_errno($ch))
{
echo 'Curl error: ' . curl_error($ch);
}
You're telling cURL to validate the SSL connection but you're not telling it what to validate against;
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
Make sure you point to an up-to-date list of CA's to trust by adding:
curl_setopt($ch, CURLOPT_CAPATH, "./cacert.pem");
If you don't have an up-to-date cacert list yourself, I'd recommend downloading the one supplied by the cURL maintainer: cacert.pem.
You want CURLOPT_CAINFO (points to a PEM file) not CURLOPT_CAPATH (which points to a directory containing PEM files).
curl_setopt($ch, CURLOPT_CAINFO, "./cacert.pem");
Warning: file_get_contents(https://graph.facebook.com/me?access_token=) [function.file- get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in /var/www/dsg/signed_request.php on line 25
I have checked and set allow_url_fopen to on in my php.ini and also made sure allow_url_fopen is on when I run phpinfo();. I am still getting the error as listed above. Does anyone know if this can be made to work somehow? Perhaps has some converted to an alternative?
You can use curl, which is actually what should be used for network requests, not file_get_contents. I don't know why Facebook started using that function in there examples. Curl has error handling and will follow redirects if you want it to, so you can figure out exactly what is happing.
You can create your own one line function like this
function viacurl($location){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $location);
curl_setopt($ch, CURLOPT_HEADER, false);
$out=curl_exec($ch);
curl_close($ch);
return rtrim($out,1);
}
And use it like this :
$response = viacurl($url);
I have a Facebook application running on Amazon servers (windows data center + apache) and this shows up in the apache error log a lot:
"Invalid or no certificate authority found, using bundled information"
In facebook.php the error is generated here:
if ((curl_errno($ch) == 60) || (curl_errno($ch) == 77)) { // CURLE_SSL_CACERT || CURLE_SSL_CACERT_BADFILE
self::errorLog('Invalid or no certificate authority found, using bundled information');
curl_setopt($ch, CURLOPT_CAINFO,
dirname(__FILE__) . '/fb_ca_chain_bundle.crt');
$result = curl_exec($ch);
}
I have the latest fb_ca_chain_bundle.crt from github in the same directory.
Download facebook.php and the fb_ca_chain_bundle.crt certificate again and replace them with your current files.
