使用网络服务器上的照片离线将照片上传到 Facebook

发布于 2024-10-29 23:41:24 字数 1428 浏览 2 评论 0原文

我到处搜索,但没有运气,找到了很多在用户处于会话中时将照片上传到 Facebook 的示例(即用户实际坐在计算机前并访问网页)。我已经尝试过这些示例,并且它们有效。

我注意到去年关于同一问题的这个未回答的问题 Stackoverflow 问题

我当前的 问题应用程序允许用户授权离线更新,我存储 access_token、user_id 等,并且当用户离线时我可以成功发布到用户墙。

我真的很难找到将照片发布到用户墙上的方法。阅读 Facebook 文档,我认为您只能使用以下方式上传照片多部分/表单数据!?!?

如果用户不在他们的计算机前,这将不起作用。您可以上传存储在我的服务器目录中的照片吗?

到目前为止,这是我的代码。请记住,这不使用 facebook 会话,因为 access_code 已预先授予并存储。正如我所提到的,在用户墙上发布信息已经可以使用这种方法。

$filename= "@/myphotodir/filename.jpg");
$url = "https://graph.facebook.com/".$uid."/photos";  //$uid is fb user id
$ch = curl_init($url);
$attachment =  array('access_token' => $access_token,
                'app_id'            => $app_id,
                'name'              => "A photo from me...",
                'fileUpload'        => true,
                'message'           => "my message",
                'image'             => $filename,
          );
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $attachment);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result= curl_exec($ch);
curl_close ($ch);

编辑:$结果返回错误...忘记添加。

任何帮助将不胜感激。 非常感谢, 院长

I've searched around everywhere without luck and found lots of examples to upload a photo to facebook when the user is in a session (i.e. the user is physically sitting at the computer and accessing the web page). I've tried the samples, and they work.

I noticed this unanswered question from last year on the same issue
Stackoverflow Question

My current app lets the user authorise off-line updates and I store the access_token, user_id, etc. and I can succesfully post to a users wall when they are offline.

I'm really struggling getting something to work with posting a photo to the users wall. Reading the Facebook documentation, I'm thinking you can only upload photos using multipart/form-data!?!?

That wouldn't work if the user isn't at their computer. Can you upload photos that are stored on a directory on my server?

Here's my code so far. Remember, this doesn't use a facebook session as the access_code has already been granted and stored beforehand. As I mentioned, posting to a users wall already works with this approach.

$filename= "@/myphotodir/filename.jpg");
$url = "https://graph.facebook.com/".$uid."/photos";  //$uid is fb user id
$ch = curl_init($url);
$attachment =  array('access_token' => $access_token,
                'app_id'            => $app_id,
                'name'              => "A photo from me...",
                'fileUpload'        => true,
                'message'           => "my message",
                'image'             => $filename,
          );
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $attachment);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result= curl_exec($ch);
curl_close ($ch);

Edit: $result comes back false... forgot to add that.

Any help would be appreciated.
Many thanks,
Dean

您应该使用 Facebook SDK。通过 Facebook SDK,您可以使用:

$facebook->setFileUploadSupport( true );
$parameters = array(
    'access_token' => 'ACCESS_TOKEN_HERE',
    'message' => 'PHOTO_CAPTION',
    'image' => '@' . realpath( '/path_to_file.jpg' ) // Notice the @ sign
);
$facebook->api( '/user_id/photos', 'post', $parameters );

这会将照片发布到他们的默认相册。如果将 user_id 替换为 album_id,则可以发布到特定相册。

You should use the Facebook SDK. With the Facebook SDK, you can use:

$facebook->setFileUploadSupport( true );
$parameters = array(
    'access_token' => 'ACCESS_TOKEN_HERE',
    'message' => 'PHOTO_CAPTION',
    'image' => '@' . realpath( '/path_to_file.jpg' ) // Notice the @ sign
);
$facebook->api( '/user_id/photos', 'post', $parameters );

This will post the photo to their default album. If you replace user_id with an album_id you can post to a specific album.
