Question

我正在尝试通过此Facebook应用程序将我保存在服务器上的照片上传到我的脸书上。

我的facebook请求最初是：

$response = (new FacebookRequest(
    $session,
    'POST',
    '/me/photos',
    array(
        'source' =>  '@' . $_FILES['file']['tmp_name'] ,
    )
))->execute()->getGraphObject()->asArray();

/* handle the result */
print_r($response);

但显然语法现在已经改变了，我需要有这样的东西：

'source'=> new CURLFile(' '),

不确定要放什么参数，因为我的图片存储在我服务器的文件夹中我的应用程序允许用户从他们的计算机浏览和提交照片。这将在发布到Facebook之前保存到服务器上。我使用了multiform / part：

<form method="post" enctype="multipart/form-data">
    Please select a photo to upload <input type="file" name="file" id="file"><br><br>
    <input type="submit" value="Upload" name="submit">
</form>

我必须将照片上传到服务器的代码如下：

if(isset($_POST['submit'])) {
    $file_type = $_FILES['file']['type']; //returns the file type
    $allowed = array("image/jpeg", "image/gif", "image/png", "image/jpg"); //specifies allowed file types
    if(!in_array($file_type, $allowed)) {
        $error_message = 'Only jpeg, jpg, gif, and png files are allowed. <br> 
        Please click back and try again.';
        echo $error_message;
        exit();
    }

$name = $_FILES['file']['name'];  //original path of the uploaded file
$temp_name = $_FILES['file']['tmp_name'];  //contains the path to the temporary file that resides on the server

if(isset($name)) {
    if(!empty($name)) {      
        $location = 'uploads/'; //save photo to the folder: uploads
        if(move_uploaded_file($temp_name, $location.$name)){
            echo 'Photo was successfully uploaded.';
        }
    }       
} 
else {
    echo 'Photo was unsuccessfully uploaded, click back and try again.';
}

我知道会话有效，因为我能够将消息发布到Facebook上。

CURLFILE方法接受一个主要参数，即路径和文件名。修改您的代码如下：

$response = (new FacebookRequest(
    $session,
    'POST',
    '/me/photos',
    array(
        'source' =>  new CURLFile( $_FILES['file']['tmp_name'] )
    )
))->execute()->getGraphObject()->asArray();

Facebook api php sdk 4.0 - 使用“new curlfile”将照片上传到Facebook
