将图片上传到Facebook

Question

我试图将图像上传到Facebook粉丝页面上的图库,这是我的代码到目前为止,

$ch = curl_init();

        $data = array('type' => 'client_cred', 'client_id' => 'app_id','client_secret'=>'secret_key',' redirect_uri'=>'http://apps.facebook.com/my-application/'); // your connect url here

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/oauth/access_token');
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

        $rs = curl_exec($ch);
        curl_close($ch);

        $ch = curl_init();
        $data = explode("=",$rs);
        $token = $data[1];

        $album_id = '1234';
        $file= 'http://my.website.com/my-application/sketch.jpg';
        $data = array(basename($file) => "@".realpath($file),
        //filename, where $row['file_location'] is a file hosted on my server
            "caption" => "test",
            "aid" => $album_id, //valid aid, as demonstrated above
            "access_token" => $token
        );

        $ch2 = curl_init();
        $url = "https://graph.facebook.com/".$album_id."/photos";
        curl_setopt($ch2, CURLOPT_URL, $url);
        curl_setopt($ch2, CURLOPT_HEADER, false);
        curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch2, CURLOPT_RETURNTRANSFER, false);
        curl_setopt($ch2, CURLOPT_POST, true);
        curl_setopt($ch2, CURLOPT_POSTFIELDS, $data);
        $op = curl_exec($ch2);

当我回显$ token时,我似乎得到了令牌,但是当我运行脚本时,我收到此错误,{"error":{"type":"OAuthAccessTokenException","message":"需要访问令牌请求这个资源."},我不知道它为什么这样做!

基本上我在该代码中正在做的是使用curl获取访问令牌,然后通过curl将照片上传到我的相册,但我一直收到错误!

任何帮助将不胜感激,谢谢!

好的，开始工作了，这里是代码，假设您正在进行有效的会话。

    $token = $session['access_token'];

    //upload photo
    $file= 'photo.jpg';
    $args = array(
    'message' => 'Photo from application',
    );
    $args[basename($file)] = '@' . realpath($file);

    $ch = curl_init();
    $url = 'https://graph.facebook.com/me/photos?access_token='.$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);

这会将指定的图像上传到会话持有者图库，如果没有，它将创建一个相册，您也可以通过会话数组访问令牌，如上所示。希望这可以帮助别人。
