#0/app/gmail。菲律宾比索(32): Google_客户端->fetchAccessTokenWithRefreshToken(NULL)

#2{main}被抛出

我修改了 getClient() 功能如下:

function getClient() {
    $client = new Google_Client();
    $client->setApplicationName(APPLICATION_NAME);
    $client->setScopes(SCOPES);
    $client->setAuthConfig(CLIENT_SECRET_PATH);
    $client->setRedirectUri(REDIRECT_URL);
    $client->setAccessType('offline');
    $client->setApprovalPrompt('force');

    // Load previously authorized credentials from a file.
    $credentialsPath = expandHomeDirectory(CREDENTIALS_PATH);

    if (file_exists($credentialsPath)) {
        $accessToken = json_decode(file_get_contents($credentialsPath), true);
    } 
    else {
        // Request authorization from the user.
        $authUrl = $client->createAuthUrl();
        return printf("<a href='%s' target='_blank'>auth</a><br />", $authUrl);
    }
    $client->setAccessToken($accessToken);

    // Refresh the token if it's expired.
    // ERROR HERE !!
    if ($client->isAccessTokenExpired()) {
        $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
    }
    return $client;
}

getClient() REDIRECT_URL callbackAuth() 执行函数:

function callbackAuth() {
    $client = new Google_Client();
    $client->setApplicationName(APPLICATION_NAME);
    $client->setScopes(SCOPES);
    $client->setAuthConfig(CLIENT_SECRET_PATH);
    $client->setRedirectUri(REDIRECT_URL);
    $client->setAccessType('offline');
    $client->setApprovalPrompt('force');

    // Load previously authorized credentials from a file.
    $credentialsPath = expandHomeDirectory(CREDENTIALS_PATH);

    // Request authorization from the user.
    $authCode = trim($_GET['code']);

    // Exchange authorization code for an access token.
    $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);

    // Store the credentials to disk.
    if(!file_exists(dirname($credentialsPath))) {
      mkdir(dirname($credentialsPath), 0700, true);
    }
    file_put_contents($credentialsPath, json_encode($accessToken));
    printf("Credentials saved to %s\n", $credentialsPath);

    $client->setAccessToken($accessToken);

    return $client;
}

我试图应用其他相关的解决方案 stackoverflow question ,但没有结果。为什么会出现这种错误?
