Set header on server, no output before header

header('Content-type: application/json');

Data assembled on the service side

echo json_encode($var);

This is caused by your service side not returning your expected JSON format, you print out the service-side output to see.

That is the data returned by the server is not a JSON format, not a front-end issue.
