将图片上传到Facebook [英] Uploading a picture to facebook

问题描述

我正在将图片上传到Facebook粉丝专页的画廊，这里是我的代码到目前为止，

I am trying to upload a image to a gallery on a facebook fan page, here is my code thus far,

$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);

当我回应$ token时，我似乎得到了令牌，但是当我运行脚本时，我收到这个错误，{error：{type：OAuthAccessTokenException，message：需要访问令牌来请求此资源。}，我不知道为什么这样做！

When I echo $token, I seem to be getting the token, but when I run the script, I get this error, {"error":{"type":"OAuthAccessTokenException","message":"An access token is required to request this resource."} , I have NO idea why it is doing this!

基本上，我在代码中做的是获取curl的访问令牌，然后通过curl将照片上传到我的相册，但是我不断得到这个错误！

Basically what I am doing in that code is getting the access token with curl, and then, uploading the photo to my album also via curl, but I keep getting that error!

任何帮助不胜感激，谢谢！

Any help would be appreciated, thank you!

推荐答案

，它的工作，这里是代码，假设你有一个有效的会话进行。

Ok, got it working, here is the code, assuming that you have a valid session going.

    $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);

这将会将指定的图像上传到会话持有者画廊，如果没有一个存在，您也可以通过会话数组访问令牌，如上所示。
希望这有助于某人出去。

This will upload the specified image to the session holders gallery, it will create a album if there is not one present, also you can access the token via the session array as demonstrated above. Hope this helps someone out.
