FAQ

How can I learn about Twitter API?

Learn from documentation.

Or watch actual response. The following tool is very very useful.

Aren't there any nice authentication tools for obtaining tokens?

Try the following commandline utility.

How do I use OAuth 2.0 authentication flow?

Sorry, it is not available with this library. Use OAuth 1.0a instead.

What is oauth_verifier ?

It is required for calling the following methods.

  • TwistOAuth::renewWithAccessToken()
  • TwistOAuth::curlPostAccessToken()

You can get it after user redirecting.

$oauth_verifier = filter_input(INPUT_GET, 'oauth_verifier');

What is oauth_callback ?

It is not required, but you can apply it for calling the following methods.

  • TwistOAuth::renewWithRequestToken()
  • TwistOAuth::curlPostRequestToken()

There are three value types.

Name Example Value Authentication Type
Empty String "" PIN or URL (Use default setting)
URL "http://example.com/callback.php" URL
Out-Of-Band "oob" PIN

WARNING:
You can only use URL if your application is configured as Browser Application.
This means Callback URL is not empty.

How do I use $to in callback closure?

Use use().

$to->streaming('user', function ($status) use ($to) { ... });

How do I ignore TwistException thrown?

Now your code is:

try {
    $to->post('statuses/update', array('status' => 'test'));
} catch (TwistException $e) { } // This is very lengthy!!!

To ignore all responses...

curl_exec($to->curlPost('statuses/update', array('status' => 'test'))); // Wow, cool

Are all classes immutable?

Yes.

$a = new TwistOAuth('CK', 'CS');
$b = $a->renewWithRequestToken();
var_dump($a === $b); // false

However, you can change propety values by directly calling __construct().

$obj = new TwistOAuth('a', 'b');
$obj->__construct('c', 'd'); // Break immutable rules

Why don't you use namespace?

This is because of the compatibility with previous versions of abraham/twitteroauth.
I believe that the prefix Twist- will never collide with any other libraries.

Tweets are already escaped... wtf!?

HTML special chars in texts of statuses are already escaped by Twitter like this.

$status->text = htmlspecialchars($status->text, ENT_NOQUOTES, 'UTF-8');

WARNING:
The flag is ENT_NOQUOTES, not ENT_QUOTES or ENT_COMPAT.
The following snippet may print broken HTML.

<input type="text" name="text" value="<?=$status->text?>">

You should do like this. Do not forget to set 4th parameter into false.

<input type="text" name="text" value="<?=htmlspecialchars(status->text, ENT_QUOTES, 'UTF-8', false)?>">

User description contains unescaped &... wtf!?

HTML special chars in others are already sanitized by Twitter like this.

$user->name        = str_replace(array('<', '>'), '', $user->name);
$user->description = str_replace(array('<', '>'), '', $user->description);

WARNING:
& is not replaced into &amp;.
The following snippet may print broken HTML.

name: <?=$user->name?><br>

You should do like this.

name: <?=htmlspecialchars($user->name, ENT_QUOTES, 'UTF-8')?><br>

cURL causes SSL certificate problem error in Windows!

In the past library, this problem was done with the following solution.

// You are saying, "Hey libcurl, do not certificate whether I'm really talking to Twitter."
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

However, it makes vulnerability for man-in-the-middle attack. Your connection can be hijacked even if using the protocol https://. This attack can be committed in the following case.

  • Some DNS servers' caches are poisoned. Refer to DNS spoofing
  • You are connecting a public access point that an attacker launched as a trap.

The right way is to download to add CA information to your computer.

1. Download ca-bundle.crt to save in the directory, which path should not contain multibyte characters.

# Good
C:\ca-bundles\ca-bundles.crt

# Bad
C:\Users\田所浩二\Documents\証明書\ca-bundles.crt

2. Add the following definition in php.ini.

curl.cainfo="C:\ca-bundles\ca-bundles.crt"

3. Restart Apache.
