Google API的問題PHP簡單查詢的例子

Question

我試圖讓Google的簡單查詢示例（關閉GitHub）工作，不幸的是確實缺乏成功......我得到的是退出代碼255。

我確定問題出在Google服務器的調用中，因此在代碼中添加了一個異常處理程序。該項目現在看起來是這樣的：

    echo pageHeader("Simple API Access");

    anonymous quota (which is limited per IP).

    set_include_path("../src/" . PATH_SEPARATOR . get_include_path());

    } catch (Exception $e) {

     echo $e->getTraceAsString()."\n"; 
    } 

    /************************************************

    array. 
    Some calls will return a single item which we 
    can immediately use. The individual responses 
    are typed as Google_Service_Books_Volume, but 
    can be treated as an array. 
    ***********************************************/ 
    echo "<h3>Results Of Call:</h3>"; 

    // update to code (off StackOverflow) 

    //foreach ($results as $item) {

    foreach($results->getItems() as $item){

    ***********************************************/ 
    //$client->setDefer(true); 
    //$optParams = array('filter' => 'free-ebooks'); 
    //$request = $service->volumes->listVolumes('Henry David Thoreau', $optParams); 
    //$results = $client->execute($request); 
    // 
    //echo "<h3>Results Of Deferred Call:</h3>"; 
    //foreach ($results as $item) { 
    // echo $item['volumeInfo']['title'], "<br /> \n"; 
    //} 
    // 
    echo pageFooter(__FILE__); 

的錯誤跟蹤如下：

任何援助將不勝感激。

注意：這可能只是一個身份驗證問題。我是一名無法訪問Google控制檯的遠程工作人員，因此必須依靠發誓提供了正確密鑰的老闆！

我實際上是在GitHub上的rowanrh。在上面發帖之後 - 沒有得到任何幫助 - 我決定在GitHub上覆制帖子。

我剛纔通過更改下面的php.ini設置解決了這個問題：

1. 我設置（通過取消註釋）擴展= p​​hp_openssl.dll - 必要的「https」網址;和
2. 我設置了時區。谷歌對時代很挑剔，所以這可能會影響結果。

在IDE（我使用PhpStorm）測試後，我重新啓動Apache，一切都很好！
