I'm testing Twilio to use as our SMS solution however I'm having issues getting it to work behind our proxy server.
I've tried:
$twiliohttp = new Services_Twilio_TinyHttp(
"https://api.twilio.com",
array("curlopts" => array(
CURLOPT_USERAGENT => self::USER_AGENT,
CURLOPT_HTTPHEADER => array('Accept-Charset: utf-8'),
CURLOPT_CAINFO => dirname(__FILE__) . '/cacert.pem',
CURLOPT_PROXY => '3.X.X.X:9400',
))
);
$client = new Services_Twilio($account_sid, $auth_token, null, $twiliohttp );
$message = $client->account->messages->sendMessage(
'+441432XXXX31', // From a Twilio number in your account
'+44776XXXX712', // Text any number
"Hello monkey!"
);
I then get the error: Fatal error: Cannot access self:: when no class scope is active in /var/www/twiliosms.php on line 16
So I modified the Twilio.php file modifying the curlopts array to add:
CURLOPT_PROXY => '3.X.X.X:9400',
and calling Twilio with:
$client = new Services_Twilio($account_sid, $auth_token );
$message = $client->account->messages->sendMessage(
'+4414XXXXXXX1', // From a Twilio number in your account
'+4477XXXXXXX2', // Text any number
"Hello monkey!"
);
But I then get the error:
Fatal error: Uncaught exception 'Services_Twilio_RestException' with message 'Could not decode response body as JSON. This likely indicates a 500 server error' in /var/www/GE/includes/SMS/Twilio.php:288

Any ideas how to make this solution work through a proxy server that doesn't allow inbound connections?
Thanks in advance.
Ricky from Twilio here.
Although I couldn't test with your exact proxy setup I think the first solution you tried will work if you hardcode the user agent. For example:
$twiliohttp = new Services_Twilio_TinyHttp(
"https://api.twilio.com",
array("curlopts" => array(
CURLOPT_USERAGENT => "Twilio Proxy/1.0",
CURLOPT_HTTPHEADER => array('Accept-Charset: utf-8'),
CURLOPT_CAINFO => dirname(__FILE__) . '/cacert.pem',
CURLOPT_PROXY => '3.X.X.X:9400',
))
);
You also may need to make the modification to the TinyHttp library shown here.
Many thanks to RickyRobinett this is how to resolve the issue, I post this answer with the full solution so people don't have to trove through the badly formatted comments.
Update TinyHttp in line with: https://github.com/camuthig/twilio-php/commit/20d4f3c4479c93894866f498e89a0f13cf16d6bf
$twiliohttp = new Services_Twilio_TinyHttp(
"https://api.twilio.com",
array("curlopts" => array(
CURLOPT_USERAGENT => "Twilio Proxy/1.0",
CURLOPT_HTTPHEADER => array('Accept-Charset: utf-8'),
CURLOPT_CAINFO => 'includes/SMS/cacert.pem',
CURLOPT_PROXY => 'X.X.X.X:9400',
))
);
$client = new Services_Twilio($account_sid, $auth_token, null, $twiliohttp );
If you don't have the cacert.pem then checkout this post https://stackoverflow.com/a/31297747/1697288

We have existing code that uses AWS PHP SDK version 1 AmazonSTS()->get_federation_token(). After upgrading to SDK version 3, the same call using the same credentials, resource and policy returns a 403 not authorized error.
Version and region appear to be the same. The policy json is the same. The user credentials used to make the call are the same (and if I switch back to the SDK v1 they still work). I have the debug option set but it doesn't appear to provide any additional information as to why the same user it not authorized to perform the same function getFederationToken on the same federated user.
Old code that works:
$client = new AmazonSTS();
$policy = new stdClass();
$policy->Statement = [
'Sid' => 'randomstatementid' . time(),
'Action' => ['s3:*'],
'Effect' => 'Allow',
'Resource' => 'aws:s3:::' . $AWS_BUCKET . '*'
];
// Fetch the session credentials.
$response = $client->get_federation_token('User1',array(
'Policy' => json_encode($policy),
'DurationSeconds' => $NUMSECS
));
New code that returns 403 error:
$client = new Aws\Sts\StsClient([
'region' => 'us-east-1',
'version' => '2011-06-15',
]);
$policy = new stdClass();
$policy->Statement = [
'Sid' => 'randomstatementid' . time(),
'Action' => ['s3:*'],
'Effect' => 'Allow',
'Resource' => 'aws:s3:::' . $AWS_BUCKET . '*'
];
try {
$response = $client->getFederationToken([
'Name' => 'User1',
'Policy' => json_encode($policy),
'DurationSeconds' => $NUMSECS,
]);
} catch (Exception $e) {
var_dump($e);
die();
}
The first example returns temporary credentials for the federated user User1.
The second example returns 403 forbidden error (I'm hiding the actual account id):
<Error>
<Type>Sender</Type>
<Code>AccessDenied</Code>
<Message>User: arn:aws:iam::[account id]:user/portal is not authorized to perform: sts:GetFederationToken on resource: arn:aws:sts::[account id]:federated-user/User1</Message>
</Error>
Turns out I was looking at the wrong credentials. I found the correct credentials hard-coded in the script :(
I have used following code make a call to twilio sipendpoint. But i'm getting call failed status.
The call flow is like this when agent click on customer number, first i'm connecting to agent to his sip url like this sip:name#sip.twilio.com on request call back i'll connect to customer number using dial verb.
The sip log gives following error
X-Twilio-Error: 400: Bad value for header: X-Twilio-OutboundRouteCount
$client = new Services_Twilio($sid, $token);
$client->account->calls->create(
'name',
'sip:name#sip.twilio.com',
'http://twiliocallback,
array(
'Record' => true,
'Method' => "GET",
'StatusCallback' => 'http://url,
'StatusCallbackMethod' => 'GET',
'StatusCallbackEvent' => array("initiated", "ringing", "answered", "completed"),
'SipAuthPassword' => '****',

I have to send a lot of emails distributed over the whole day with ZF2 and I'm using Zend\Mail\Transport\Smtp. I have the mails in a queue table and once a minute I want to send them. Everything works fine until 5th email, where I receive an error : Zend\Mail\Protocol\Exception\RuntimeException
4.7.0 Too many RSET commands; closing connection
I guess this is coming from the smtp server. But why does ZF2-Smtp reset each message? I don't know where to start debugging the problem and if you need more informations just let me know. Thx for any help...
What I'm using is:
$transport = new SmtpTransport();
$options = new SmtpOptions(array(
'host' => $config['mail_options']['server'],
'port' => $config['mail_options']['port'],
'connection_class' => 'login',
'connection_config' => array(
'username' => $config['mail_options']['smtp_user'],
'password' => $config['mail_options']['smtp_password'],
'ssl' => $config['mail_options']['ssl'],
),
));
foreach ($queuedMails as $queuedMail) {
$message = new Message();
$message->addTo($data['to'])
->addFrom($config['mail_options']['from'], $config['mail_options']['from_name'])
->setSubject($data['subject'])
->setBody(utf8_decode($data['body']))
->setEncoding('utf-8');
$transport->setOptions($options);
$transport->send($message);enter code here
}
Should I place the $transport into the foreach?
I apologize for asking so many questions but none of them seem to be getting answered and I really need help on this. I'm using LTI to integrate my program into a learning management system, and I need to authenticate using OAuth. I have no trouble generating a signature following the guidelines here but the signature I generate never matches the one passed to me by the LMS, and I can't figure out for the life of me why they never match. I'm hoping that it's something I'm oblivious to, but I really need some assistance on this.
When I launch my program from the LMS, I am sent this array via POST in what is called the LTI launch:
array(
'launch_presentation_locale' => 'EN-US__',
'tool_consumer_instance_guid' => 'key',
'tool_consumer_instance_name' => 'MyProgram',
'tool_consumer_instance_description' => 'MyProgram',
'tool_consumer_instance_contact_email' => 'johndoe#email.com',
'tool_consumer_info_version' => '10.3.0 SP5',
'tool_consumer_info_product_family_code' => 'desire2learn',
'context_id' => '2440554',
'context_title' => 'ContextTitle',
'context_label' => 'ContextTitle',
'context_type' => '',
'user_id' => 'USER_ID',
'roles' => 'None',
'lis_person_name_given' => 'John',
'lis_person_name_family' => 'Doe',
'lis_person_name_full' => 'John Doe',
'lis_person_contact_email_primary' => 'johndoe#email.com',
'ext_tc_profile_url' => 'https://profileurl.com',
'ext_d2l_token_id' => '123456789',
'ext_d2l_link_id' => '1234',
'ext_d2l_token_digest' => 'AbCdEfGhIjKlMnOpQrStUvWxYzi=',
'resource_link_id' => '',
'resource_link_title' => 'MyProgram',
'resource_link_description' => 'MyProgram',
'lis_result_sourcedid' => 'abcdefgh-ijkl-mnop-qrst-uvwxyz012345',
'lis_outcome_service_url' => 'https://outcomeserviceurl.com',
'lti_version' => 'LTI-1p0',
'lti_message_type' => 'basic-lti-launch-request',
'oauth_version' => '1.0',
'oauth_nonce' => '123456789',
'oauth_timestamp' => '1234567890',
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_consumer_key' => 'key',
'oauth_callback' => 'about:blank',
'oauth_signature' => 'eFUR8O5xVydLrj4PDj37nF4cq6A=',
'basiclti_submit' => 'Launch Endpoint with BasicLTI Data'
);
Here is what I'm trying. I've added comments to clarify the steps:
// Set variables that are required for the signature to be generated.
$OAUTH_KEY = 'key';
$OAUTH_SECRET = 'secret';
$httpMethod = 'POST';
$SITE_URL = 'https://localhost/test.php';
// make array copy of entire POST data, remove the 'oauth_signature' field as specified in the oauth spec from the copy array, then sort alphabetically. After that, url encode the key/value of each item in the copy array and store into a string for later use.
$request_parameter_array = $_POST;
unset($request_parameter_array['oauth_signature']);
ksort($request_parameter_array);
$request_parameter_str = '';
foreach($request_parameter_array as $key => $value) {
$request_parameter_str .= rawurlencode($key) . '=' . rawurlencode($value) . '&';
}
// create the signature base string (string variable that the actual signature is created from) by following these steps from the OAuth documentation:
// 1. The HTTP request method in uppercase. For example: "HEAD",
// "GET", "POST", etc. If the request uses a custom HTTP method, it
// MUST be encoded (Section 3.6).
// 2. An "&" character (ASCII code 38).
// 3. The base string URI from Section 3.4.1.2, after being encoded
// (Section 3.6).
// 4. An "&" character (ASCII code 38).
// 5. The request parameters as normalized in Section 3.4.1.3.2, after
// being encoded (Section 3.6).
$key = rawurlencode($OAUTH_SECRET) . '&';
$signature_base = strtoupper($httpMethod) . '&' . rawurlencode($SITE_URL) . '&';
$signature_base .= rawurlencode($request_parameter_str);
$signature = base64_encode(hash_hmac("sha1", $signature_base, $key, true));
echo $signature;
I guess my own stupidity was the issue, here. The issue was arising from D2L itself because I misunderstood what the difference was between using a tool link vs. a tool provider for my integrations. I literally deleted my tool provider and went with a tool link and now I'm able to authenticate every time.
Turns out there wasn't a problem with the code at all here.
I am working with YouTube APIs for my college project, and I keep getting an error. Here I send them to the authorisation page to log in, when they allow access it sends the $_GET['code'] string back. Then I send this along with some other data and it should send back a JSON object. Instead I am just getting
Warning: file_get_contents(https://accounts.google.com/o/oauth2/token)
[function.file-get-contents]: failed to open stream: HTTP request
failed! HTTP/1.0 400 Bad Request in http://www.example.net/callback.php on line 27
I have replaced my domain with example.net just for security
urlencode($_GET['code']),
'client_id' => urlencode('111522767640.apps.googleusercontent.com '),
'client_secret' => urlencode('secret'),
'redirect_uri' => urlencode('http://example.net/callback.php'),
'grant_type' => urlencode('authorization_code')
)
);
$params =
array('http' =>
array(
'method' => 'POST /o/oauth2/token HTTP/1.1',
'header' => 'Host: accounts.google.com\r\n'.
'Content-Type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($params);
$result = file_get_contents('https://accounts.google.com/o/oauth2/token', false,$context);
var_dump($_SESSION);
var_dump($result);
}
else //If code isnt set, user must have come here erroniously or has denied access to this program
{
//header( 'Location: www.example.net/error.php' ) ;
}
?>
file_get_contents is going to make a GET request to the url specified, but oauth2/token needs a POST request.
See reference Google OAuth2, PHP HTTP.
if you are using oauth2, goto libraries/oauth2/provider.php and uncomment the code line 182 shows
$ci = get_instance();
$ci->load->spark('curl/1.2.1');
$ci->curl
->create($url)
->post($params, array('failonerror' => false));
$response = $ci->curl->execute();
Here's how to do the Google oAuth properly:
$config = (object) array(
'CLIENT_ID' => 'AAAAA',
'CLIENT_SECRET' => 'BBBBB',
'REFRESH_TOKEN' => 'CCCCC',
);
$sJSON = file_get_contents('https://www.googleapis.com/oauth2/v4/token',FALSE,
stream_context_create(array('http'=>array(
'ignore_errors' => TRUE, // see errors in response instead of empty on error
'method' => 'POST',
'header' => array(
'Content-Type: application/x-www-form-urlencoded'
),
'content' => http_build_query(array(
'grant_type' => 'refresh_token',
'client_id' => $config->CLIENT_ID,
'client_secret' => $config->CLIENT_SECRET,
'refresh_token' => $config->REFRESH_TOKEN
))
)))
);
You can then use json_decode() to parse $sJSON into an object and then retrieve the access_token property.
For those who are wondering how to get the CLIENT_ID, CLIENT_SECRET, and REFRESH_TOKEN, watch this video. It's not easy. In my case, I needed to do this for Google Adwords API. So, I had to get my Developer Token and Login Customer ID from https://ads.google.com/home/tools/manager-accounts. Then, I had to go to https://console.developers.google.com/apis/credentials with this guide to generate a Client ID and Client Secret. Then, I followed this guide to learn how to get my Refresh Token.
