Debugging Requests
|
|
------------------
|
|
|
|
Sometimes the library generates unexpected output. The simplest way to debug is
|
|
to examine the HTTP request that twilio-php actually sent over the wire. You
|
|
can turn on debugging with a simple flag:
|
|
|
|
.. code-block:: php
|
|
|
|
require('Services/Twilio.php');
|
|
|
|
$client = new Services_Twilio('AC123', '456bef');
|
|
$client->http->debug = true;
|
|
|
|
Then make requests as you normally would. The URI, method, headers, and body
|
|
of HTTP requests will be logged via the ``error_log`` function.

|
require: Failed to open stream messages
|
|
-----------------------------------------
|
|
|
|
If you are trying to use the helper library and you get an error message that
|
|
looks like this:
|
|
|
|
.. code-block:: php
|
|
|
|
PHP Warning: require(Services/Twilio.php): failed to open stream: No such
|
|
file or directory in /path/to/file
|
|
|
|
Fatal error: require(): Failed opening required 'Services/Twilio.php'
|
|
(include_path='.:/usr/lib/php:/usr/local/php-5.3.8/lib/php') in
|
|
/Library/Python/2.6/site-packages/phpsh/phpsh.php(578): on line 1
|
|
|
|
Your PHP file can't find the Twilio library. The easiest way to do this is to
|
|
move the Services folder from the twilio-php library into the folder containing
|
|
your file. So if you have a file called ``send-sms.php``, your folder structure
|
|
should look like this:
|
|
|
|
.. code-block:: bash
|
|
|
|
.
|
|
├── send-sms.php
|
|
├── Services
|
|
│ ├── Twilio.php
|
|
│ ├── Twilio
|
|
│ │ ├── ArrayDataProxy.php
|
|
│ │ ├── (..about 50 other files...)
|
|
|
|
If you need to copy all of these files to your web hosting server, the easiest
|
|
way is to compress them into a ZIP file, copy that to your server with FTP, and
|
|
then unzip it back into a folder in your CPanel or similar.
|
|
|
|
You can also try changing the ``require`` line like this:
|
|
|
|
.. code-block:: php
|
|
|
|
require('/path/to/twilio-php/Services/Twilio.php');
|
|
|
|
You could also try downloading the library via PEAR, a package manager for PHP,
|
|
which will add the library to your PHP path, so you can load the Twilio library
|
|
from anywhere. Run this at the command line:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ pear channel-discover twilio.github.com/pear
|
|
$ pear install twilio/Services_Twilio
|
|
|
|
If you get the following message:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ -bash: pear: command not found
|
|
|
|
you can install PEAR from their website.

SSL Validation Exceptions
|
|
-------------------------
|
|
|
|
If you are using an outdated version of `libcurl`, you may encounter
|
|
SSL validation exceptions. If you see the following error message, you have
|
|
a SSL validation exception: ::
|
|
|
|
Fatal error: Uncaught exception 'Services_Twilio_TinyHttpException'
|
|
with message 'SSL certificate problem, verify that the CA cert is OK.
|
|
|
|
Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate
|
|
verify failed' in [MY PATH]\Services\Twilio\TinyHttp.php:89
|
|
|
|
This means that Twilio is trying to offer a certificate to verify that you are
|
|
actually connecting to `https://api.twilio.com <https://api.twilio.com>`_, but
|
|
your curl client cannot verify our certificate.
|
|
|
|
There are four solutions to this problem:
|
|
|
|
Upgrade your version of the twilio-php library
|
|
==============================================
|
|
|
|
Since November 2011, the SSL certificate has been built in to the helper
|
|
library, and it is used to sign requests made to our API. If you are still
|
|
encountering this problem, you can upgrade your helper library to the latest
|
|
version, and you should not encounter this error anymore.
|
|
|
|
If you are using an older version of the helper library, you can try one of the
|
|
following three methods:
|
|
|
|
Upgrade your version of libcurl
|
|
===============================
|
|
|
|
The Twilio certificate is included in the latest version of the
|
|
``libcurl`` library. Upgrading your system version of ``libcurl`` will
|
|
resolve the SSL error. `Click here to download the latest version of
|
|
libcurl <http://curl.haxx.se/download.html>`_.
|
|
|
|
Manually add Twilio's SSL certificate
|
|
=====================================
|
|
|
|
The PHP curl library can also manually verify an SSL certificate. In your
|
|
browser, navigate to
|
|
`https://github.com/twilio/twilio-php/blob/master/Services/cacert.pem
|
|
<https://github.com/twilio/twilio-php/blob/master/Services/cacert.pem>`_
|
|
and download the file. (**Note**: If your browser presents ANY warnings
|
|
at this time, your Internet connection may be compromised. Do not download the
|
|
file, and do not proceed with this step). Place this file in the same folder as
|
|
your PHP script. Then, replace this line in your script:
|
|
|
|
.. code-block:: php
|
|
|
|
$client = new Services_Twilio($sid, $token);
|
|
|
|
with this one:
|
|
|
|
.. code-block:: php
|
|
|
|
$http = new Services_Twilio_TinyHttp(
|
|
'https://api.twilio.com',
|
|
array('curlopts' => array(
|
|
CURLOPT_SSL_VERIFYPEER => true,
|
|
CURLOPT_SSL_VERIFYHOST => 2,
|
|
CURLOPT_CAINFO => getcwd() . "/cacert.pem")));
|
|
|
|
$client = new Services_Twilio($sid, $token, "2010-04-01", $http);
|
|
|
|
Disable certificate checking
|
|
============================
|
|
|
|
A final option is to disable checking the certificate. Disabling the
|
|
certificate check means that a malicious third party can pretend to be
|
|
Twilio, intercept your data, and gain access to your Account SID and
|
|
Auth Token in the process. Because this is a security vulnerability,
|
|
we **strongly discourage** you from disabling certificate checking in
|
|
a production environment. This is known as a `man-in-the-middle attack
|
|
<http://en.wikipedia.org/wiki/Man-in-the-middle_attack>`_.
|
|
|
|
If you still want to proceed, here is code that will disable certificate
|
|
checking:
|
|
|
|
.. code-block:: php
|
|
|
|
$http = new Services_Twilio_TinyHttp(
|
|
'https://api.twilio.com',
|
|
array('curlopts' => array(CURLOPT_SSL_VERIFYPEER => false))
|
|
);
|
|
|
|
$client = new Services_Twilio('AC123', 'token', '2010-04-01', $http);
|
|
|
|
If this does not work, double check your Account SID, token, and that you do
|
|
not have errors anywhere else in your code. If you need further assistance,
|
|
please email our customer support at `help@twilio.com`_.
