PHP Post array empty on axios POST

Question

I\'m trying out Vue 2.0 and axios and I\'ve got a little issue. When I try to send a post request using axios to my post.php file the $_POST array is always empty.

Answer 1

For me the problem was that I was using http instead of https in the url. The server returned http status code Permanently moved (to the https site). A browser or command line client (curl) follow these redirects. My code did not. Solution was to use https in the url.

Answer 2

The data that is send with axios is not put into PHP's $_POST. Instead, it is in the request body and most likely in json format. To get it, try the following code:

function getRequestDataBody()
{
    $body = file_get_contents('php://input');

    if (empty($body)) {
        return [];
    }

    // Parse json body and notify when error occurs
    $data = json_decode($body, true);
    if (json_last_error()) {
        trigger_error(json_last_error_msg());
        return [];
    }

    return $data;
}


$data = getRequestDataBody();
var_dump($data)

Or you could use FormData like the other answer suggests.

Answer 3

I think you can try this, it should be the data-type problem.

var data = new FormData();
data.append('title', 'foo');
data.append('body', 'bar');

axios.post('api/post.php', data)
    .then(response => {
        console.log(response)
        console.log(response.data)
        this.filter = response.data
    })
    .catch(e => {
        this.errors.push(e)
});
