（更新）Laravel PUT方法不起作用

Question

• updated - the JSON file would return but it will not change the billing date at all.

• Reference 1: The official documentation about changing the billing date.

• Reference2: their sample code in detail:

  <?php
  
  $request = new HttpRequest();
  $request->setUrl('https://domain.chargify.com/subscriptions/$subscriptionId.json');
  $request->setMethod(HTTP_METH_PUT);
  
  $request->setHeaders(array(
    'authorization' => 'Basic YXBpa2V5Og==',
    'content-type' => 'application/json'
  ));
  
  $request->setBody('{"subscription":{"next_billing_at":"2028-12-15"}}');
  
  try {
    $response = $request->send();
    echo $response->getBody();
  } catch (HttpException $ex) {
    echo $ex;
  }
  

My code in detail:

   public function changeYearlySubscriptionBillingDate(Request $request)
{
    $user = $request->user();
    $subscriptionId = $user->subscription->subscription_id;
    $nextBilling = Carbon::now()->addYear();
    $hostname = env('CHARGIFY_HOSTNAME');

    $headers = [
        'authorization' => 'Basic ANIDIANDIAJIJCQ',
        'content-type' => 'application/json'
    ];

    $body = ["subscription" => ["next_billing_at" =>[ $nextBilling ]]];

    $config = [
        'headers' => $headers,
        'form_param' => $body
    ];

    $client = new Client($config);

    $res = $client->put("https://$hostname/subscriptions/$subscriptionId.json",
    ["json" => [
    [ "subscription" =>
        [ "next_billing_at" => $nextBilling ]
    ]
]
]);

    echo $res->getBody();
}

Answer 1

thanks everyone so much for helping me out.

I've been working on this problem for 2 days and it was supposed to be right to me. Eventually, it is their API that misled me.

the only thing we need to do, is simply change

'body' => "{\"subscription\":{\"next_billing_at\":\"$nextBilling\"}}"

added a few '\' s inside.

Thanks everyone for helping me out, have a good day!
