文件上传停止工作

Question

虽然我没有更改任何内容，但自从我更改了网络主机后，此工作文件上传已停止工作。

我检查了我是否可以上传文件，并且最大文件大小设置为 256MB，所以问题不存在。我上传的目录也将 CHMOD 设置为 777。

PHP 版本为 5.6.15

将文件上传到我的服务的客户端位于同一个域中。

这是我的客户端代码：

error_reporting(E_ALL);

$uploaddir = 'tempUploads/';
$random_file_name = uniqid(rand(), true);
$file_extension = pathinfo(basename($_FILES['fileToUpload']['name']), PATHINFO_EXTENSION);
$uploadfile = $uploaddir . basename($_FILES['fileToUpload']['name']);
$optional_id = $_POST['optional_id'];
$upload_type = $_POST['upload_type'];

if (move_uploaded_file($_FILES['fileToUpload']['tmp_name'], $uploadfile)) 
{   
    $ch = curl_init();

    $filepath = str_replace('\\', '/', realpath(dirname(__FILE__))) . "/";  
    $target_path = $filepath . $uploadfile; 
    var_dump(file_exists($target_path));
    $data = array('optional_id' => $optional_id, 'file' => '@'.$target_path, 'upload_type' => $upload_type);    

    curl_setopt($ch, CURLOPT_URL, 'http://domain.dk/webservice/v1/uploadFile');
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $curl_response = curl_exec($ch);

    if ($curl_response === false) 
    {
        $info = curl_getinfo($curl);
        curl_close($curl);
        die('error occured during curl exec. Additioanl info: ' . var_export($info));
    }   
} 
else 
{
    echo "Kunne ikke uploade filen";
} 

如您所见，我在 target_path 上做了一个 var_dump，这表明文件已上传到客户端临时文件夹。我检查了文件夹，文件已按预期上传到该文件夹​​。

我的服务函数如下所示：

$app->post('/uploadFile', 'authenticate', function() use ($app) 
{   
$optional_id = $app->request->post('optional_id');
$upload_type = $app->request->post('upload_type');
$file = $app->request->post('file');
$uploaddir = "";
// set directory where file needs to be saved
switch($upload_type)
{
    case 1:
        $uploaddir = '../uploadedContent/calibrationCertificate/';
        break;
    case 2:
        $uploaddir = '../uploadedContent/educationCertificate/';
        break;
    default:            
}


// random file name to avoid overwriting existing files.
$random_file_name = uniqid(rand(), true);
// extension of the file
$file_extension = pathinfo(basename($_FILES['file']['name']), PATHINFO_EXTENSION);
// full path and name
$uploadfile = $uploaddir . $random_file_name.".".$file_extension;


if(move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile))
{
    $db = new DbHandler(); 

    switch($upload_type)
    {
        case 1:
            $db->insertEquipmentDocumentRef($optional_id,$uploadfile,basename($_FILES['file']['name']));    
            break;
        case 2:
            $db->insertEducationDocumentRef($optional_id,$uploadfile,basename($_FILES['file']['name']));
            break;
        default:            
    } 

    $response["error"] = false;
    $response["message"] = "filen blev uploadet";
    $response["optional_id"] = $optional_id;
    $response["upload_type"] = $upload_type;
    $response["uploadfile"] = $file;
}
else
{
    $response["error"] = false;
    $response["message"] = "filen kunne ikke uploades";
    $response["dir"] = $uploadfile;
    $response["dir"] = $uploadfile;
    $response["move from"] = pathinfo(basename($_FILES['file']['name']));
    if(!$_FILES)
    {
        $response["file"] = "File does not exist";
    }

}

echoRespnse(201, $response);

});

您应该再次注意到，在 move_uploaded_files 失败后，我在代码底部检查了 $_FILES 是否为空。检查我的浏览器调试器显示 $_FILES 为空。

$_FILES 变量怎么设置为 null ？ .. 在我更换虚拟主机之前它运行顺利...

我认为可能出错的唯一地方是我通过 postfields 数组将文件“中继”到服务但我不确定：

$data = array('optional_id' => $optional_id, 'file' => '@'.$target_path, 'upload_type' => $upload_type);

据此，@filename 在 PHP >= 5.5.0 中似乎已被弃用： Can anyone give me an example for PHP's CURLFile class?
