facebook api：计算活动的参加者数量（限制问题）

发布于 2024-10-25 07:29:40 字数 743 浏览 1 评论 0原文

好吧，通常我对 facebook API 没什么问题，但我遇到了一个让我想知道的问题。（我认为这是一个错误（检查票证 http://bugs.developers.facebook。 net/show_bug.cgi?id=13694），但如果有人有想法，我想把它扔在这里）。

我正在使用 facebook PHP 库来计算特定活动的所有与会者，

$attending = $facebook->api('/'.$fbparams['eventId'].'/attending');

这可以正常工作，它可以正确返回包含所有与会者的数组...

现在问题是：

此活动现在有大约 18.000 名与会者。 API 调用返回最多 992 名与会者（而不是应有的 18000 人）。

我尝试

$attending = $facebook->api('/'.$fbparams['eventId'].'/attending?limit=20000');

进行测试，但它没有改变任何东西。

所以我真正的问题是：

如果我无法通过使用图形 api 让它工作，什么是一个好的替代方案？（也许解析事件页面的 html？）现在我每隔几个小时手动更改该值，这是乏味且不必要的。

Okay normally I'm all fine about the facebook API but I'm having a problem which just keeps me wondering. (I think it's a bug (Check ticket http://bugs.developers.facebook.net/show_bug.cgi?id=13694) but I wanted to throw it here if somebody has an idea).

I'm usng the facebook PHP library to count all attendees for a specific event

$attending = $facebook->api('/'.$fbparams['eventId'].'/attending');

this works without a problem it correctly returns an array with all attendees...

now heres the problem:

This event has about 18.000 attendees right now.
The api call returns a max number of 992 attendees (and not 18000 as it should).

I tried

$attending = $facebook->api('/'.$fbparams['eventId'].'/attending?limit=20000');

for testing but it doesn't change anything.

So my actual question is:

If I can't get it to work by using the graph api what would be a good alternative? (Parsing the html of the event page maybe?) Right now I'm changing the value by hand every few hours which is tedious and unnecessary.

实际上有两个参数，limit和offset。我认为您必须同时使用两者并继续拨打电话，直到其中一个返回的值小于最大值。限制。

像这样的东西，但是采用递归方法（我正在编写伪代码）：

offset = 0;
maxLimit = 992;
totalAttendees = count(result)

if (totalAttendees >= maxLimit)
{
  // do your stuff with each attendee
  offset += totalAttendees;
  // make a new call with the updated offset
  // and check again
}

Actually there are two parameters, limit and offset. I think that you will have to play with both and continue making calls until one returns less than the max. limit.

Something like this, but in a recursive approach (I'm writting pseudo-code):

offset = 0;
maxLimit = 992;
totalAttendees = count(result)

if (totalAttendees >= maxLimit)
{
  // do your stuff with each attendee
  offset += totalAttendees;
  // make a new call with the updated offset
  // and check again
}

我搜索了很多，这就是我修复它的方法：
请求的网址应类似于此。

<一href="https://developers.facebook.com/tools/explorer/145634995501895/?method=GET&path=738667559524648%3Faccess_令牌%3D603913936305026%257CyZYvULhJhDcrsVaGzJmendOpHDw%26fields%3Dattending_count%2Cinvited_count&version=v2.2" rel="nofollow">这里是您可以测试它的地方，这是我使用的代码：

function events_get_facebook_data($event_id) {
  if (!$event_id) {
    return false;
  }

  $token = klicango_friends_facebook_token();
  if ($token) {
    $parameters['access_token'] = $token;
    $parameters['fields']= 'attending_count,invited_count';
    $graph_url = url('https://graph.facebook.com/v2.2/' . $event_id , array('absolute' => TRUE, 'query' => $parameters));
    $graph_result = drupal_http_request($graph_url, array(), 'GET');
    if(is_object($graph_result) && !empty($graph_result->data)) {
      $data = json_decode($graph_result->data);
      $going = $data->attending_count;
      $invited = $data->invited_count;
      return array('going' => $going, 'invited' => $invited);
    }
    return false;
  }

  return false;
}

I've searched a lot and this is how I fixed it:
The requested URL should look something like this.

Here is where you can test it and here is the code I used:

function events_get_facebook_data($event_id) {
  if (!$event_id) {
    return false;
  }

  $token = klicango_friends_facebook_token();
  if ($token) {
    $parameters['access_token'] = $token;
    $parameters['fields']= 'attending_count,invited_count';
    $graph_url = url('https://graph.facebook.com/v2.2/' . $event_id , array('absolute' => TRUE, 'query' => $parameters));
    $graph_result = drupal_http_request($graph_url, array(), 'GET');
    if(is_object($graph_result) && !empty($graph_result->data)) {
      $data = json_decode($graph_result->data);
      $going = $data->attending_count;
      $invited = $data->invited_count;
      return array('going' => $going, 'invited' => $invited);
    }
    return false;
  }

  return false;
}
