PHP提示：未定义的索引

PHP提示：未定义的索引

4

我正在使用Zendesk PHP类，下面的函数用于删除附件。

/**
 * Delete one or more attachments by token or id
 * $params must include one of these:
 *        'token' - the token given to you after the original upload
 *        'id' - the id of the attachment
 *
 * @param array $params
 *
 * @throws MissingParametersException
 * @throws ResponseException
 * @throws \Exception
 *
 * @return bool
 */
public function delete(array $params) {
    if(!$this->hasAnyKey($params, array('id', 'token'))) {
        throw new MissingParametersException(__METHOD__, array('id', 'token'));
    }
    $endPoint = Http::prepare(($params['token'] ? 'uploads/'.$params['token'] : 'attachments/'.$params['id']).'.json');
    $response = Http::send($this->client, $endPoint, null, 'DELETE');
    if ($this->client->getDebug()->lastResponseCode != 200) {
        throw new ResponseException(__METHOD__);
    }
    $this->client->setSideload(null);
    return true;
}

根据评论，运行此函数时需要令牌或ID。我尝试使用了一个ID。

$attachment = $client->attachments()->delete(array('id'=>'1187146218','token'));

然而它不断抛出异常。

  PHP Notice:  Undefined index: token in /home/adam/web/srv11/public_html/vendor/zendesk/zendesk_api_client_php/src/Zendesk/API/Attachments.php on line 106
PHP Fatal error:  Uncaught exception 'Zendesk\API\ResponseException' with message 'Response to Zendesk\API\Attachments::delete is not valid. Call $client->getDebug() for details' in /home/adam/web/srv11/public_html/vendor/zendesk/zendesk_api_client_php/src/Zendesk/API/Attachments.php:109

your help is highly appreciated

要么需要token，要么需要id...你正在传递一个包含2个索引但只有1个值的数组。你可以尝试删除 ,'token' 或将其更改为 array('id'=>'1187146218','token'=>null) 但我认为未定义的索引是那个token部分。 - RightClick

你写的方式

array('id'=>'1187146218','token')

实际上会得到这样一个数组：

array('id'=>'1187146218', 0 => 'token')

因此，没有“token”索引。如果您只更改为，则应该有效。

$attachment = $client->attachments()->delete(array('id'=>'1187146218','token' => NULL));
