如何从POST获取图像？

Question

I am working with an API for mobile devices which allow the user to post image. Where I'm receiving POST variables I'm using this:

 public function endTimesAction()
 {
        $request = Request::createFromGlobals();
        $arrivalTime = $request->request->get('arrivalTime', 0);
 }

How can I get the image from post and save it somewhere on my server?

You are going to want to create a form add a file field Then handle the request on the form and save the file.

use Symfony\Component\HttpFoundation\Request;

...

public function handleFileUploadAction(Request $request)
{
    $form = $this->get('form.factory')->createNamedBuilder('')
        //Using the createNamedBuilder on the form factory service will remove the form[] wrapper around the field names
        ->add('uploaded_file','file')
        ->getForm();
    if($request->isMethod('post')){
        $form->handleRequest($request);
        if($form->isValid()){
            $file = $form['uploaded_file']->getData()->move($dir, $someNewFilename);
        }
    }
}

From the article you linked it looks like the app is going to post the data to the path using the property name uploaded_file. Even though you arent technically using an html form view there is still a "form" being submitted to your web app which is why you will use symfony forms to handle the submission.
