使用curl的示例

向特定设备发送消息

要将消息发送到特定设备，请将该设置为特定应用实例的注册令牌

curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>"  -X POST -d '{ "data": { "score": "5x1","time": "15:10"},"to" : "<registration token>"}' https://fcm.googleapis.com/fcm/send

向主题发送消息

这里的主题是:/topics/foo-bar

curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>"  -X POST -d '{ "to": "/topics/foo-bar","data": { "message": "This is a Firebase Cloud Messaging Topic Message!"}}' https://fcm.googleapis.com/fcm/send

向设备组发送消息

向设备组发送消息与向单个设备发送消息非常相似。将to参数设置为设备组的唯一通知键

curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>"  -X POST -d '{"to": "<aUniqueKey>","data": {"hello": "This is a Firebase Cloud Messaging Device Group Message!"}}' https://fcm.googleapis.com/fcm/send

使用服务API的示例

火网址:https://fcm.googleapis.com/fcm/send

头

Content-type: application/json
Authorization:key=<Your Api key>

请求方式:POST

请求体

发送到特定设备的消息

{
  "data": {
    "score": "5x1",
    "time": "15:10"
  },
  "to": "<registration token>"
}

主题的消息

{
  "to": "/topics/foo-bar",
  "data": {
    "message": "This is a Firebase Cloud Messaging Topic Message!"
  }
}

给设备组的消息

{
  "to": "<aUniqueKey>",
  "data": {
    "hello": "This is a Firebase Cloud Messaging Device Group Message!"
  }
}

这是使用CURL实现的

function sendGCM($message, $id) {


    $url = 'https://fcm.googleapis.com/fcm/send';

    $fields = array (
            'registration_ids' => array (
                    $id
            ),
            'data' => array (
                    "message" => $message
            )
    );
    $fields = json_encode ( $fields );

    $headers = array (
            'Authorization: key=' . "YOUR_KEY_HERE",
            '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_POSTFIELDS, $fields );

    $result = curl_exec ( $ch );
    echo $result;
    curl_close ( $ch );
}

?>

$message是你要发送给设备的消息

$id是设备注册令牌

YOUR_KEY_HERE是你的服务器API密钥(或遗留的服务器API密钥)

$response = Http::withHeaders([
            'Content-Type' => 'application/json',
            'Authorization'=> 'key='. $token,
        ])->post($url, [
            'notification' => [
                'body' => $request->summary,
                'title' => $request->title,
                'image' => 'http://'.request()->getHttpHost().$path,
                
            ],
            'priority'=> 'high',
            'data' => [
                'click_action'=> 'FLUTTER_NOTIFICATION_CLICK',
                
                'status'=> 'done',
                
            ],
            'to' => '/topics/all'
        ]);

下面是我使用CURL的项目中的工作代码。

<?PHP
//Avoid keys confusions!
//firebase Cloud Messaging have 3 different keys: 
//API_KEY, SERVER_KEY and PUSH_KEY ... here we need SERVER_KEY

// SERVER access key from Google firebase Console    
define( 'SERVER_ACCESS_KEY', 'YOUR-SERVER-ACCESS-KEY-GOES-HERE' );


 $registrationIds = array( $_GET['id'] );

  // prep the bundle
 $msg = array
 (
   'message'    => 'here is a message. message',
    'title'     => 'This is a title. title',
    'subtitle'  => 'This is a subtitle. subtitle',
    'tickerText'    => 'Ticker text here...Ticker text here...Ticker text here',
    'vibrate'   => 1,
    'sound'     => 1,
    'largeIcon' => 'large_icon',
    'smallIcon' => 'small_icon'
 );

 $fields = array
 (
    // use this to method if want to send to topics
    // 'to' => 'topics/all'
    'registration_ids'  => $registrationIds,
     'notification'         => $msg
 );

 $headers = array
 (
    'Authorization: key=' . SERVER_ACCESS_KEY,
    'Content-Type: application/json'
 );

 $ch = curl_init();
 curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send' );
 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, json_encode( $fields ) );
 $result = curl_exec($ch );
 curl_close( $ch );

 echo $result;

例如，您可以使用用于谷歌云消息传递(GCM)的PHP脚本。Firebase及其控制台位于GCM之上。

我在github上找到了这个: https://gist.github.com/prime31/5675017

提示:这个PHP脚本会产生一个android通知。

因此:如果你想在Android中接收和显示通知，请阅读来自Koot的回答。

如果你想从android发送推送通知，请查看我的博客文章

发送推送通知从一个android手机到另一个没有服务器。

发送推送通知只不过是发送到https://fcm.googleapis.com/fcm/send的请求

使用volley的代码片段:

    JSONObject json = new JSONObject();
 try {
 JSONObject userData=new JSONObject();
 userData.put("title","your title");
 userData.put("body","your body");

json.put("data",userData);
json.put("to", receiverFirebaseToken);
 }
 catch (JSONException e) {
 e.printStackTrace();
 }

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest("https://fcm.googleapis.com/fcm/send", json, new Response.Listener<JSONObject>() {
 @Override
 public void onResponse(JSONObject response) {

Log.i("onResponse", "" + response.toString());
 }
 }, new Response.ErrorListener() {
 @Override
 public void onErrorResponse(VolleyError error) {

}
 }) {
 @Override
 public Map<String, String> getHeaders() throws AuthFailureError {

Map<String, String> params = new HashMap<String, String>();
 params.put("Authorizationey=" + SERVER_API_KEY);
 params.put("Content-Typepplication/json");
 return params;
 }
 };
 MySingleton.getInstance(context).addToRequestQueue(jsonObjectRequest);
