How to get post values from formData in Controller ( Symfony )

Question

I created a REST Api. From the front i send post values with axios. (i use ReactJS). In Back with Symfony, in my Controller i want to get post values. How can i do ? I did it:

from the front:

const data = new FormData();

       let postData = {
            source: 'lcl',
            userLastname: lastname,
            userFirstname: firstname,
            text: message,
        }

data.append('data', postData);

Axios.post('http://127.0.0.1:8000/send', data)
        .then(function (response) {
            console.log(response);
        })
        .catch(function (error) {
            console.log(error)
        });

And from my back in Controller i try this:

$data = $request->request->get('data');

the value return [object Object]... How can i get the value (source, userLastname etc.).

Thank you for help.

you should decode your data:

$data = $request->request->get('data');

if (!empty($data)) {
    $array = json_decode($data, true); // 2nd param to get ass array
    $userLastname =  $array['userLastname']; // etc...
}

Now $array will be an array full of your JSON data. Remove the true parameter value in the json_decode() call to get a stdClass object.

Could youprovide the result of dump($array) and the dump($data)?

That's not true. Symfony will convert the payload to an array. You don't need to decode. See my answer.

@msphn could refer me a link in the symfony doc how symony with deserilize the json object automatically

Sorry, you need github.com/symfony-bundles/json-request-bundle. Thought it’s in the default. Guess it even is depending on the skeleton
