如何将这些数据发送到Facebook? Facebook api照片上传 [英] how do i send this data to facebook? facebook api photo upload

问题描述

好的，facebook要我发送本地存储在服务器上的图像，但是我将图像存储在数据库的BLOB中...

Okay so facebook want me to send an image stored locally on the server but i have the images stored in a BLOB in the database...

try {
     $file = 'http://blaze-craft.com/matt/get.php?id=' . $lastid;
    $post_data = array(
        "message" => "Uploaded using the Funnymemes app!",
         "source" => $file
     );
    $data['photo'] = $facebook->api("/me/photos", 'post', $post_data);

  }
  catch (FacebookApiException $e) {

  }

但是它没有上传...我从facebook api doc那里获得了这段代码，所以我不确定发生了什么事情

but its not uploading... I got this code from the facebook api doc's so im not sure whats going on?

有什么想法吗?

推荐答案

要使照片上传正常工作，您必须解决以下问题:

In order to photo upload to work you have to fix these:

1. 图像文件应存储在文件系统中(即将BLOB保存回 磁盘)
2. 在$post_data数组中的图像路径之前使用 @.

1. Image files should be stored in filesystem (i.e. save BLOB back to the disk)
2. Use @ before image path in $post_data array.

为此，我会做类似的事情:

For this purpose i would do something like:

try
{
    $url    = 'http://blaze-craft.com/matt/get.php?id=' . $lastid;
    $saveas = '/images/image.jpg';
    $res = @file_put_contents($saveas, file_get_contents($url));

    if($res === false) throw new Exception('Cannot fetch image');

    $post_data = array(
        "message" => "Uploaded using the Funnymemes app!",
        "source"  => '@' . $saveas;
     );
    $data['photo'] = $facebook->api("/me/photos", 'post', $post_data);

  }
  catch (FacebookApiException $e) {  }
  catch (Exception $e) { }
