我想使用FCM发送通知。我已将项目添加到Firebase控制台获得API密钥和device_token。
现在我从PHP发送推送通知，我在日志中收到消息，但它显示了一些异常。我已按照此tutorial。
PHP脚本功能：
function sendInvite()
{
$database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME);
$dbConnection = $database->getDB();
$stmt = $dbConnection->prepare("select * from Invitation where user_name =? and sender_id = ?");
$stmt->execute(array($this->user_name,$this->sender_id));
$rows = $stmt->rowCount();
if ($rows > 0) {
$response = array("status" => -3, "message" => "Invitation exists.", "user_name" => $this->user_name);
return $response;
}
$this->date = "";
$this->invitee_no = "";
$this->status = "0";
$this->contact_id = 0;
$stmt = $dbConnection->prepare("insert into Invitation(sender_id,date,invitee_no,status,user_name,contact_id) values(?,?,?,?,?,?)");
$stmt->execute(array($this->sender_id, $this->date, $this->invitee_no, $this->status, $this->user_name,$this->contact_id));
$rows = $stmt->rowCount();
$Id = $dbConnection->lastInsertId();
$stmt = $dbConnection->prepare("Select device_id from Users where user_id =?");
$stmt->execute(array($this->sender_id));
$result = $stmt->fetch(PDO::FETCH_ASSOC);
$token = $result["device_id"];
$server_key = 'AIzaJaThyLm-PbdYurj-bYQQc';
$fields = array();
$fields['data'] = $data;
if(is_array($token)){
$fields['registration_ids'] = $token;
}else{
$fields['to'] = $token;
}
//header with content_type api key
$headers = array(
'Content-Type:application/json',
'Authorization:key='.$server_key
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
$result = curl_exec($ch);
if ($result === FALSE) {
die('FCM Send Error: ' . curl_error($ch));
}
curl_close($ch);
echo $result;*/
$message = 'Hi,add me to your unique contact list and you never need to update any changes anymore!';
$data = array("message"=>"Hi,add me to your unique contact list and you never need to update any changes anymore!","title"=>"You got an Invitation.");
if (!empty($token)) {
$url = 'https://fcm.googleapis.com/fcm/send';
$fields = array(
'to' => $token,
'data' => $data
);
$fields = json_encode($fields);
$headers = array(
'Authorization: key=' . "AIzaSyBGwwJaThyLm-PhvgcbdYurj-bYQQ7XmCc",
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
$result = curl_exec($ch);
echo $result;
curl_close($ch);
}
$stmt = $dbConnection->prepare("select * from Invitation where invitation_id=?");
$stmt->execute(array($Id));
$invitation = $stmt->fetch(PDO::FETCH_ASSOC);
if ($rows < 1) {
$response = array("status" => -1, "message" => "Failed to send Invitation., unknown reason");
return $response;
} else {
$response = array("status" => 1, "message" => "Invitation sent.", "Invitation:" => $invitation);
return $response;
}
}

resultIntent.putExtra("message", message);
// check for image attachment
if (TextUtils.isEmpty(imageUrl)) {
showNotificationMessage(getApplicationContext(), title, message, timestamp, resultIntent);
} else {
// image is present, show notification with image
showNotificationMessageWithBigImage(getApplicationContext(), title, message, timestamp, resultIntent, imageUrl);

} catch (Exception e) {

例外：

这里出了什么问题？
我还希望通知响应。因为它应该有“接受和拒绝”选项，并且单击它，我想执行一个操作。
有人可以帮忙吗？谢谢..

尝试使用手动设备令牌传递下面的示例
<?php
define("ANDROID_PUSHNOTIFICATION_API_KEY",'API_KEY_HERE'); // FCM
define("ANDROID_PUSHNOTIFICATION_URL",'https://fcm.googleapis.com/fcm/send'); // FCM
function push_android($devicetoken,$param){
$apiKey = ANDROID_PUSHNOTIFICATION_API_KEY; //demo
$registrationIDs[] = $devicetoken;
// Set POST variables
$url = ANDROID_PUSHNOTIFICATION_URL;
$fields = array(
'registration_ids' => $registrationIDs,
'data' => $param,
);
$headers = array(
'Au
thorization: key=' . $apiKey,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
// Execute post
$result = curl_exec($ch);
//print_r($result); exit;
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}else{
//echo "success notification";
//print_r($result);
//echo curl_error($ch);
}
// Close connection
curl_close($ch);
return $result;
} ?>
希望这会有所帮助！

使用特殊字符时抛出此异常。请在fullstop之前删除。 要使其像添加接受和拒绝一样响应，您可以查看firebase文档 this is a good explanation
