Question

我正在使用Abraham William的TwitterOAuth包构建应用程序。该应用程序运行正常，但我遇到了一个问题。

大约25％尝试安装应用的用户无法这样做。他们在Twitter页面上验证应用程序，然后单击“登录”（在Twitter的网站上）。当它们被引回Callback.php页面时，它会给它们一个空白页面。我无法弄清楚出了什么问题，因为它适用于大多数用户。有什么想法吗？

这是callback.php代码：

<?php

require_once("config_db.php");

session_start();
// Include class & create
require_once("consumer-keys.php");
require_once("twitteroauth/twitteroauth/twitteroauth.php");
// User has selected to DENY access
if(!empty($_GET["denied"])) {
  // could re-direct or display cancelled view/template
  // we're just echoing out a message
  echo "No deal! <a href='login.php'>Try again?</a>";
  die();
}

// User has selected to ALLOW access for given token
if($_GET["oauth_token"] == $_SESSION["oauth_token"]) {
  // Use generated request tokens (from session) to construct object
  $tOAuth = new TwitterOAuth($consumerKey, $consumerSecret, $_SESSION["oauth_token"], $_SESSION["oauth_token_secret"]);
  // Retrieve access token from Twitter
  $accessToken = $tOAuth->getAccessToken();

    //echo "RECEIVED TOKENS<br>";
  // Check we have valid response
  if(is_numeric($accessToken["user_id"]))  {
    // Save the access tokens to a DB (we're using a session)
    $_SESSION["access_token"] = $accessToken;

    //GET CREDENTIALS VIA API
    $credentials = $tOAuth->get('account/verify_credentials');

    //echo "HAS NUMERIC ID<br>";

    //ISAAC ADD DB INFO
    $query = "SELECT * FROM `t4i_app`.`users_twitter` WHERE user_id = '".$_SESSION["access_token"]["user_id"]."'";
    $rs = mysql_query($query);
    if(mysql_num_rows($rs)) {

        //update query
        //echo "user already exists..need to update";
        $query = "UPDATE  `t4i_app`.`users_twitter` SET  `token` =  '".$_SESSION["access_token"]["oauth_token"]."', `secret` =  '".$_SESSION["access_token"]["oauth_token_secret"]."', `screen_name` =  '".$credentials->screen_name."', `followers` = '".$credentials->followers_count."'  WHERE  `users_twitter`.`user_id` = '".$_SESSION["access_token"]["user_id"]."';";
        mysql_query($query);
    } else {

        $query = "INSERT INTO  `t4i_app`.`users_twitter` (`id` ,`screen_name` ,`token` ,`secret`, `user_id`, `followers`, `referer` ,`last_update` ,`date_registered`) VALUES (NULL, '".$credentials->screen_name."', '".$_SESSION["access_token"]["oauth_token"]."', '".$_SESSION["access_token"]["oauth_token_secret"]."', '".$_SESSION["access_token"]["user_id"]."', '".$credentials->followers_count."', '0', CURRENT_TIMESTAMP , CURRENT_TIMESTAMP);";
        mysql_query($query);

    }
    //echo $query;
    //echo mysql_error();
    //print_r($_SESSION["access_token"]);
    $message = array('status' => 'Test OAuth update. #testoauth');
    $test = $tOAuth->post('statuses/update', array('status' => 'I just added the new APPNAME Twitter Application http://bit.ly/sampleurl'));
    //echo "POSTED STATUS<br>";


    //END ISAAC




    // Remove request token session variables
    unset($_SESSION["oauth_token"]);
    unset($_SESSION["oauth_token_secret"]);
    // Redirect to main page
    header("location: http://www.mydomain.com/welcome.php");
  } else {
    //echo "TRYING TO REDIRECT <br>";

    header("location: http://www.mydomain.com");
  }
}
?>

if ($_GET["oauth_token"] == $_SESSION["oauth_token"])

你会想要在其他地方放置一个error_log，如果get和session中的oauth_tokens不匹配，你就会失败而没有任何消息。可能是Twitter没有正确回应。
此外，我会在标题调用中将位置大写。我不是100％，当它不是位置时，每个浏览器都会尊重它：
