Abraham Williams Twitter OAuth 303 Error_问答_开发者

EDIT: I'm sorry for making this thread as I've figured out the problem.

Here's what happened: First, I noticed that the URL being sent lacked a "/" between .com and account/verify_credentials. When I updated that, I got a 404 error. Then I looked at the twitteroauth.php and I noticed that the top one:

/* Set up the API root URL. */
public $host = "https://api.twitter.com/1/";
//  public $host = "https://dev.twitter.com";

was commented out. I uncommented it, and commented out the lower one (which I'm guessing is no defunct or not used?) and now it works perfectly fine!

Thanks everybody, and thanks Mr. Williams for a great Oauth library!

I've been implementing Abraham Williams Twitter OAuth library and it's been going well so far until I tried to do something with it after connecting to Twitter. That's when I was getting a 303 HTTP code. I then changed my implementation to the way he implements it on his github site, and I still get the same issue. Does anyone have an idea of what's happening?

apitest.php is where the problem occurs, where the $connection variable has a 303 HTTP code. The corresponding $connection variables in redirect.php and callback.php both return a 200. By the way, all of the files are in the same directory.

Here's the code:

connect.php (The HTML on this page has a button that goes to redirect.php)

<?php
/**
* @file
* Check if consumer token is set and if so send user to get a request token.
*/

/**
* Exit with an error message if the CONSUMER_KEY or CONSUMER_SECRET is not defined.
*/
require_once('twitconfig.php');
if (CONSUMER_KEY === '' || CONSUMER_SECRET === '') {
  echo 'A consumer key and secret are required.';
  exit();
}

?>

redirect.php

<?php

/* Start session and load library. */
session_start();
require_once('twitteroauth.php');
require_once('twitconfig.php');

/* Build TwitterOAuth object with client credentials. */
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);

/* Get temporary credentials. */
$request_token = $connection->getRequestToken(OAUTH_CALLBACK);

/* Save temporary credentials to session. */
$_SESSION['oauth_token'] = $token = $request_token['oauth_token'];
$_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret'];

/* If last connection failed don't display authorization link. */
switch ($connection->http_code) {
  case 200:
    /* Build authorize URL and redirect user to Twitter. */
    $url = $connection->getAuthorizeURL($token);
    header('Location: ' . $url);
    break;
  default:
    /* Show notification if something went wrong. */
    echo 'Could not connect to Twitter. Refresh the page or try again later.';
}

?>

callback.php

<?php

/**
 * @file
 * Take the user when they return from Twitter. Get access tokens.
 * Verify credentials and redirect to based on response from Twitter.
 */

/* Start session and load lib */
session_start();
require_once('twitteroauth.php');
require_once('twitconfig.php');

/* If the oauth_token is old redirect to the connect page. */
if (isset($_REQUEST['oauth_token']) && $_SESSION['oauth_token'] !== $_REQUEST['oauth_token']) {
  $_SESSION['oauth_status'] = 'oldtoken';
  header('Location: ./clearsessions.php');
}

/* Create TwitteroAuth object with app key/secret and token key/secret from default phase */
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $_SESSION['oauth_token'], $_SESSION['oauth_token_secret']);

/* Request access tokens from twitter */
$access_token = $connection->getAccessToken($_REQUEST['oauth_verifier']);

/* Save the access tokens. Normally these would be saved in a database for future use. */
$_SESSION['access_token'] = $access_token;

/* Remove no longer needed request tokens */
unset($_SESSION['oauth_token']);
unset($_SESSION['oauth_token_secret']);


/* If HTTP response is 200 continue otherwise send to connect page to retry */
if (200 == $connection->http_code) {
  /* The user has been verified and the access tokens can be saved for future use */
  $_SESSION['status'] = 'verified';
  header('Location: ./apitest.php');
} else {
  /* Save HTTP status for error dialog on connnect page.*/
  header('Location: ./clearsessions.php');
}

?>

apitest.php (where the problem is seen via a print_r)

<?php

session_start();
require_once('twitteroauth.php');
require_once('twitconfig.php');

if (empty($_SESSION['access_token']) || empty($_SESSION['access_token']['oauth_token']) || empty($_SESSION['access_token']['oauth_token_secret'])) {
    header('Location: ./clearsessions.php');
}

/* Get user access tokens out of the session. */
$access_token = $_SESSION['access_token'];

/* Create a TwitterOauth object with consumer/user tokens. */
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $access_token['oauth_token'], $access_token['oauth_token_secret']);


/* Get logged in user to help with tests. */
$user = $connection->get('account/verify_credentials');

print_r($connection);

print_r($_SESSION);

?>

The output of the first print statement is:

The output of the second print statement is:

Array ( 
[access_token] => Array ( 
[oauth_token] => 351699791-F6stFFk81poF8ooORgLLxaE2cpSdDT2Vr0Tz9yJm 
[oauth_token_secret] => q8fHaTaFvOUL8XKYX89LSgubr2fSl1xHBUAi8MUqIc 
[user_id] => 351699791 
[screen_name] => jibjib21 ) 
[status] => verified )

Does anyone have an idea of what's going on with this 303 error and how to resolve it? Any help would be greatly appreciated. Thanks!

A 303 response is a redirect. My guess is you need to add .json (or whatever format you are using) to the end of the URL you are requesting.

I.e. instead of 'account/verify_credentials', you need to request 'account/verify_credentials.json'.
