使用PHP调用Outlook API续期通知订阅时PATCH请求报错求助

Hey there, let's break down this error and get your subscription renewal working smoothly!

What's Causing the Error? #

That error message is pretty straightforward: your PATCH request isn't sending the required JSON request body. The Outlook API's subscription renewal endpoint (PATCH /me/subscriptions/{id}) expects a JSON object containing a new expiration date for the subscription. Right now, you're passing null as the body parameter to your runCurl method—so the API receives an empty request, which it can't parse into the expected JSON structure, hence the "EndOfInput" error.

How to Fix It #

You need to add a valid request body that includes the ExpirationDateTime field (formatted as an ISO 8601 timestamp). Outlook subscriptions have a maximum duration of 30 days, so we'll set the expiration to 30 days from now in this example.

Here's the modified code:

$token = json_decode($account->token, true);
$newToken = json_decode($sync->refreshToken($token['refresh_token']), true);

// Create the renewal request body: set a new expiration date (max 30 days allowed)
$expirationDateTime = date('c', strtotime('+30 days'));
$requestBody = json_encode([
    'ExpirationDateTime' => $expirationDateTime
]);

$headers = array(
    "Content-Type: application/json",
    "Authorization: Bearer " . $newToken['access_token']
);
$url = "https://outlook.office.com/api/v2.0/me/subscriptions/" . $token['events_hookId'];
$res = $emailSync->runCurl($url, $requestBody, $headers, "PATCH");
print_r($res);

Key Notes to Keep in Mind #

• Verify your runCurl method: Make sure it properly handles the request body for PATCH requests—some custom curl wrappers might ignore the body unless explicitly configured to send it for non-POST methods.
• Stick to the expiration limit: Outlook won't accept subscriptions longer than 30 days, so don't set ExpirationDateTime to more than 30 days in the future, or you'll hit another error.
• Timestamp format: The date('c') function generates a valid ISO 8601 timestamp (e.g., 2024-11-20T14:30:00+00:00), which is exactly what the API expects.
