无法在php中获取google-calendar-api请求的结果（仅限终端）

Question

我在使用谷歌日历api时遇到了一些麻烦，这里：https://developers.google.com/calendar/quickstart/php有一个要执行的php文件，以便在日历中获取崩溃事件（文件名为quickstart.php）。

当我在我的Windows终端上使用命令'$ php quickstart.php'执行它时，它运行得很好，终端中会显示一个结果。

我想在php中得到结果，所以我可以使用它或者至少在网页上显示它，但是一旦我用导航器启动页面，我就会收到错误“致命错误：未捕获异常：此应用程序必须是在命令行上运行。“这是在quickstart.php的开头创建的。我怎样才能使它工作？将结果输入变量并使用它？

谢谢您的反馈！

该示例旨在作为已安装的应用程序运行，并不打算在Web上运行。您将使用的代码和客户端是不同的。实际调用api是一样的。

您需要做的第一件事是转到开发人员控制台并创建浏览器凭据。

oauth2callback.php

   require_once __DIR__ . '/vendor/autoload.php';
    require_once __DIR__ . '/Oauth2Authentication.php';
    // Start a session to persist credentials.
    session_start();
    // Handle authorization flow from the server.
    if (! isset($_GET['code'])) {
        $client = buildClient();
        $auth_url = $client->createAuthUrl();
        header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
    } else {
        $client = buildClient();
        $client->authenticate($_GET['code']); // Exchange the authencation code for a refresh token and access token.
        // Add access token and refresh token to seession.
        $_SESSION['access_token'] = $client->getAccessToken();
        $_SESSION['refresh_token'] = $client->getRefreshToken();    
        //Redirect back to main script
        $redirect_uri = str_replace("oauth2callback.php",$_SESSION['mainScript'],$client->getRedirectUri());    
        header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
    }

Oauth2Authentication.php

require_once __DIR__ . '/vendor/autoload.php';
/**
 * Gets the Google client refreshing auth if needed.
 * Documentation: https://developers.google.com/identity/protocols/OAuth2
 * Initializes a client object.
 * @return A google client object.
 */
function getGoogleClient() {
    $client = getOauth2Client();
    // Refresh the token if it's expired.
    if ($client->isAccessTokenExpired()) {
        $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
    }
return $client;
}
/**

function buildClient(){

    $client = new Google_Client();
    $client->setAccessType("offline");        // offline access.  Will result in a refresh token
    $client->setIncludeGrantedScopes(true);   // incremental auth
    $client->setAuthConfig(__DIR__ . '/client_secrets.json');
    $client->addScope([YOUR SCOPES HERE]);
    $client->setRedirectUri(getRedirectUri());  
    return $client;
}
/**

 */
function getRedirectUri(){
    //Building Redirect URI
    $url = $_SERVER['REQUEST_URI'];                    //returns the current URL
    if(strrpos($url, '?') > 0)
        $url = substr($url, 0, strrpos($url, '?') );  // Removing any parameters.
    $folder = substr($url, 0, strrpos($url, '/') );   // Removeing current file.
    return (isset($_SERVER['HTTPS']) ? "https" : "http") . '://' . $_SERVER['HTTP_HOST'] . $folder. '/oauth2callback.php';

function getOauth2Client() {
    try {

        $client = buildClient();

        // Set the refresh token on the client. 
        if (isset($_SESSION['refresh_token']) && $_SESSION['refresh_token']) {

            // Set the access token on the client.
            $client->setAccessToken($_SESSION['access_token']);                 

            // Refresh the access token if it's expired.

您需要的代码重置可以在我的示例项目Calendar v3上找到

我也有一个教程，但我认为上面的示例代码是更新的qazxsw poi
