设置HTTP请求的状态

Question

I tried to set the http status in my custom API when a request is being made.

protected $statusCode = 200;

public function setStatusCode($statusCode) {
        $this->statusCode = $statusCode;
        return $this;
    }

public function respond($data, $headers = []) {
        return response()->json($data, $this->getStatusCode(), $headers);
    }

public function respondCreated($message) {
    return $this->setStatusCode(201)->respond([
        'message' => $message
    ]);
}

$this->respondCreated("Incident was created");

But when I make my server request in POSTMAN, I see status 200 and not 201 as set in the code above and the message is not appearing at all. Do I need to do it differently?

I am using the Laravel framework and implemented the functions by the book "Build APIs you won't hate"

I used the http_response_code() method as suggested and set the code like this:

public function respondCreated($message) {
    $this->setStatusCode(201)->respond([
        'message' => $message
    ]);
    http_response_code(201);
    return $this;
}

When I then return the response code it shows properly, but the POSTMAN Status is still 200?

The helper method by laravel is response() and is described as:

Returning a full Response instance allows you to customize the response's HTTP status code and headers. A Response instance inherits from the Symfony\Component\HttpFoundation\Response class, providing a variety of methods for building HTTP responses:

use Illuminate\Http\Response;

Route::get('home', function () {
    return (new Response($content, $status))
                  ->header('Content-Type', $value);
});
For convenience, you may also use the response helper:

Route::get('home', function () {
    return response($content, $status)
                  ->header('Content-Type', $value);
});

You can set the HTTP Response Code as stated on PHP documentation.

<?php

// Get the current default response code
var_dump(http_response_code()); // int(200)

// Set our response code
http_response_code(404);

// Get our new response code
var_dump(http_response_code()); // int(404)
?>
