我还在使用 React Native Callkeep 和 Twilio 进行视频通话。

这对我们适用于 iOS 和 Android，即使应用被用户明确杀死。

APN 请求

$url = "https://api.sandbox.push.apple.com/3/device/<device_token>";
$headers = array(
    "apns-push-type: voip",
    "apns-expiration: 10",
    "apns-topic: com.example.app.voip", // .voip as suffix to bundleID
    "apns-collapse-id: lcall", 
    "Content-Type: application/x-www-form-urlencoded",
);
$certificate_file = config('pushnotification.apn.certificate');
$payloadArray['aps'] = [
    'alert' => [
        'title' => "Calling title",
        'body' => "Calling body",
    ],
    'badge' => 1,
    "content-available" => 1
];
$data = json_encode($payloadArray);
$client = new Client();
$response = $client->post($url, [
    'headers' => $headers,
    'cert' => $certificate_file,
    'curl' => [
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_2_0,
    ],
