Twitter Stream API - 401 Unauthorized

问题

I can't open a connection with Twitter Stream API. The only response I can get, no matter what I try, is 401 Unauthorized.

I've made all kinds of tests, even using some libraries I've found on GitHub.

Even outside my code, using cURL, I can't make it work.

$oauth = array( 
    'oauth_consumer_key' => $this->m_oauth_consumer_key,
    'oauth_nonce' => time(),
    'oauth_signature_method' => 'HMAC-SHA1',
    'oauth_token' => $this->m_oauth_token,
    'oauth_timestamp' => time(),
    'oauth_version' => '1.0'
);

$base_info = $this->buildBaseString($this->url, 'GET', $oauth);
$composite_key = rawurlencode($this->m_oauth_consumer_secret) . '&' . rawurlencode($this->m_oauth_token_secret);
$oauth_signature = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
$oauth['oauth_signature'] = $oauth_signature;
$header = $this->buildAuthorizationHeader($oauth);

This is my code for building HTTP Request Header and Signature. I've tried in a lot of different ways, no success.

Anoyone have any ideia that could help me?

Thank you in advance.

If you're on Linux, sync your time with an NTP server:

$ sudo ntpdate ntp.org

I was trying to access the API today with node.js and had the same error. My Windows didn't yet update my clock, so my local computer time was off by an hour(daylight saving time switch was today). When I changed it, it started to work again. They should really have some better error message than just plain 401.

I had the same problem. Go to your App Settings screen and change Callback URL to something like yoursite.com. I'm not sure why but once you change that you won't see 401 error anymore.
