PHP - 通过Graph API将网络托管照片上传到Facebook相册
我正在尝试上传www托管(例如 http:/ /www.google.se/intl/en_com/images/srpr/logo1w.png )文件到Facebook相册。
I'm trying to upload www hosted (e.g. http://www.google.se/intl/en_com/images/srpr/logo1w.png) files to a facebook album.
创建专辑很好,但我似乎没有上传任何照片。我正在使用Facebook php-sdk( http://github.com/facebook/php-sdk / ),我已经尝试的例子是:
Creating an album works just fine, but I don't seem to uploading any photos. I'm using the facebook php-sdk ( http://github.com/facebook/php-sdk/ ) and the examples I already tried are:
如何使用Facebook Graph API将照片上传到相册
我猜猜CURL上传也许只能管理本地存储的文件,而不是网络托管的文件。
I'm guessing CURL uploads perhaps only can manage locally stored files and not web hosted ones.
这是我的代码: p>
Here's my code:
/*
Try 1:
$data = array();
$data['message'] = $attachment->post_title;
$data['file'] = $attachment->guid;
try {
$photo = $facebook->api('/' . $album['id'] . '/photos?access_token=' . $session['access_token'], 'post', $data);
} catch (FacebookApiException $e) {
error_log($e);
}
*/
// Try 2:
//upload photo
$file = $attachment->guid;
$args = array(
'message' => 'Photo from application',
);
$args[basename($file)] = '@' . realpath(file_get_contents($file));
$ch = curl_init();
$url = 'https://graph.facebook.com/' . $album['id'] . '/photos?access_token=' . $session['access_token'];
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
$data = curl_exec($ch);
//returns the photo id
print_r(json_decode($data,true));
...附件 - > guid包含照片网址。
...where attachment->guid contains the photo url.
我现在很困难了...
I'm pretty much stuck right now...
我认为问题在这里:
$args[basename($file)] = '@' . realpath(file_get_contents($file));
因为你想从另一个来源张贴图片(对?),你应该暂时保存你自己的主机。
since you want to post a picture from another source (right?), you should save it temporarily on your own host.
我也需要做这样的事情,因为我不得不处理图像,我使用以下方式:
i also needed to do something like this, and since i had to process the image, i used the following way:
$im = @imagecreatefrompng('http://www.google.se/intl/en_com/images/srpr/logo1w.png');
imagejpeg($im, 'imgs/temp/temp.jpg', 85);
$args['image'] = '@' . realpath('imgs/temp/temp.jpg');
其余的看起来很好,虽然
the rest looks fine though
