現在我知道這是一個通過互聯網特別是StackOverflow的常見話題。但是我沒有的(或者還沒有看到的)對於在會話中維護的令牌是直接的解決方案。使用PHP的Google URL縮短API
我正在使用Google APIs Client Library for PHP。
我的查詢: 我有使用Google_Oauth2Service從PHP客戶端的lib一個的index.php其中I取用戶數據(如姓名)。用戶認證成功,一切順利。現在我想使用網址縮短服務,因此我有一個shorten.php,我有代碼嘗試獲取短網址。一些如何這不起作用。
的index.php
//include google api files
require_once 'src/Google_Client.php';
require_once 'src/contrib/Google_Oauth2Service.php';
require_once 'src/contrib/Google_UrlshortenerService.php';
//start session
session_start();
$gClient = new Google_Client();
$gClient->setApplicationName('Test App');
$gClient->setClientId($google_client_id);
$gClient->setClientSecret($google_client_secret);
$gClient->setRedirectUri($google_redirect_url);
$gClient->setDeveloperKey($google_developer_key);
$google_oauthV2 = new Google_Oauth2Service($gClient);
....
....
在這裏,我已經開始了會議,並取得了Google_Client的對象。我已經宣佈客戶ID,祕密和所有其他細節。
然後,我在成功認證時獲取訪問令牌並將其存儲在Session變量中,以便當我嘗試從shorten.php中獲取短url(使用jQuery ajax)時,可以使用現有的令牌。
$_SESSION['token'] = $gClient->getAccessToken();
....
現在shorten.php
session_start();
require_once 'src/Google_Client.php';
require_once 'src/contrib/Google_Oauth2Service.php';
require_once 'src/contrib/Google_UrlshortenerService.php';
$gClient = new Google_Client();
$gClient->setApplicationName('Test App');
$gClient->setClientId($google_client_id);
$gClient->setClientSecret($google_client_secret);
$gClient->setRedirectUri($google_redirect_url);
$gClient->setDeveloperKey($google_developer_key);
....
if (isset($_SESSION['token']) && $_SESSION['token']) {
// Set the access token from the session
$gClient->setAccessToken($_SESSION['token']);
$url_service = new Google_UrlshortenerService($gClient);
// Check if a URL has been passed
if (isset($_GET['url'])) {
$url = new Google_Url();
$url->longUrl = $_GET['url'];
$shortURL = $url_service->url->insert($url);
....
這是代碼打破$shortURL = $url_service->url->insert($url);
我成功地讓使用Session變量的令牌,並創建了一個成功的URL服務對象的確切行。但就在我調用插入方法的時候,那是失敗的時候。
從Apache的錯誤日誌:

當我倒在的index.php和shorten.php文件Google_Client變量,這是我得到的。
的index.php
Google_Client Object

[scopes:protected] => Array

[useObjects:protected] =>
[services:protected] => Array
(
[oauth2] => Array
(
[scope] => Array

[1] => https://www.googleapis.com/auth/userinfo.email
)
)
)
[authenticated:Google_Client:private] =>
)
shorten.php
object(Google_Client)#1 (4) {
["scopes":protected]=>
array(0) {
}
["useObjects":protected]=>
bool(false)
["services":protected]=>
array(1) {
["urlshortener"]=>
array(1) {
["scope"]=>
string(44) "https://www.googleapis.com/auth/urlshortener"
}
}
["authenticated":"Google_Client":private]=>
bool(false)
}
兩者是不是一樣的,所以我假設有一些東西不就在這裏。請幫助或指導。
