Laravel 5: Retrieve JSON array from $request

Solution 1:

You need to change your Ajax call to

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    contentType: "json",
    processData: false,
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

change the dataType to contentType and add the processData option.

To retrieve the JSON payload from your controller, use:

dd(json_decode($request->getContent(), true));

instead of

dd($request->all());

Solution 2:

 $postbody='';
 // Check for presence of a body in the request
 if (count($request->json()->all())) {
     $postbody = $request->json()->all();
 }

This is how it's done in laravel 5.2 now.

Solution 3:

Just a mention with jQuery v3.2.1 and Laravel 5.6.

Case 1: The JS object posted directly, like:

$.post("url", {name:'John'}, function( data ) {
});

Corresponding Laravel PHP code should be:

parse_str($request->getContent(),$data); //JSON will be parsed to object $data

Case 2: The JSON string posted, like:

$.post("url", JSON.stringify({name:'John'}), function( data ) {
});

Corresponding Laravel PHP code should be:

$data = json_decode($request->getContent(), true);

Solution 4:

You can use getContent() method on Request object.

$request->getContent() //json as a string.
