我正在使用Abraham William的TwitterOAuth軟件包構建應用程序。該應用程序工作正常,除了我遇到一個問題。Abraham Williams Twitter oAuth PHP回調問題
約25%的用戶嘗試安裝應用程序不能這樣做。他們在Twitter頁面上驗證應用程序並點擊「登錄」(在Twitter的網站上)。當它們返回到Callback.php頁面時,它會給它們一個空白頁面。我無法弄清楚什麼是錯誤的,因爲它適用於大多數用戶。有任何想法嗎?
這裏是callback.php代碼:
<?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");
}
}

[啓用] [錯誤日誌](http://php.net/manual/en/errorfunc.configuration.php)* *爲您的PHP應用程序。空白頁面是某處發生致命錯誤的標誌。因此,如果您啓用了錯誤日誌記錄,則會發現記錄了這些錯誤。這將幫助你找出偶爾發生的事情。如果您還記錄了警告和通知,您甚至可能會發現更多的錯誤來幫助您獲得腳本的工作。 – hakre
謝謝你的提示。我確實啓用了錯誤日誌記錄,並且我一直在監視日誌但沒有相關的錯誤。任何其他想法? –
