这是在CakePhp3中创建和发布多部分表单数据的正确方法吗?

CakePhp3中的多部件表单数据 . 表单应该包含一些关于用户的信息(文本字段)和图像。

我在做这样的事情:

$request = [
  'fistname'=>$user->firstname,
  'lastname'=>'$user->lastname',
  '_session'=>'$session'
];

$form = new FormData();
foreach ($request as $key => $value) {
  $form->add($key,$request);
}
$file = $form->addFile('upload',fopen(WWW_ROOT.'img/picture.png','r'));
$file->contentId('mypicture'); // <-- not sure what this is
$file->disposition('attachment');

$response = $http->post(
  $url,
  (string)$form,
  ['headers' => ['Content-Type' => $form->contentType()]]
);

谢谢你的帮助。

object(Cake\Http\ServerRequest) {
trustProxy => false
...
[protected] data => [
    'fistname' => [
        'fistname' => 'Test',
        'lastname' => 'Test'
    ],
    'lastname' => [
        'fistname' => 'Test',
        'lastname' => 'Test'
    ],
    'upload' => [
        'tmp_name' => '/private/var/folders/g5/jjd1vc557bs21hq805lcxjk80000gn/T/phpAVXNqK',
        'error' => (int) 0,
        'name' => 'SELL5BAE2B6348272_gallery_1.png',
        'type' => 'image/png',
        'size' => (int) 200231
    ]
]
...

如果我发布到API服务器,它就不工作了。 我对卷曲也做了同样的处理,效果很好:

$filename = WWW_ROOT.'ufiles/medium/'.$img['image_1'];
$cFile = curl_file_create($filename);
$request = [
  '_operation'=>'uploadFile',
  'id'=>$ticket_id,
  '_session'=>$session,
  'file' => $cFile
];

try{
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_URL,$this->crm['endpoint']);
  curl_setopt($ch, CURLOPT_POST,1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
  $response=curl_exec($ch);
  curl_close ($ch);
}catch(\Exception $e){
  $response = null;
}
