使用 OneSignal 发送通知 b/w 台设备

Question

您好，我正在尝试在 android 应用的两个用户 A 和 B 之间发送推送通知。使用 OneSignal 网站是一种手动方式，我想通过应用程序本身发送通知，比如用户 A 按下按钮，通知将发送给用户 B。任何帮助将不胜感激。

Answer 1

要使用 OneSignal 发送自定义通知，您需要使用 OneSignal 的授权和通知结构 URL 可以与您分享我的代码。

https://onesignal.com/api/v1/notifications

传递这些headers

Content-Type application/json; charset=UTF-8
Authorization Basic <your-rest-client-key>

在下面 JSON 设置到您的 body

{
  "app_id": "<your-app-id>",
  "included_segments": ["All"],
  "content_available":"true",
  "data": {"foo": "bar"},
  "contents": {"en": "Test_Message_Body"},
  "headings": {"en": "Test_Message_Title"}
}

这是来自OneSignal官方博客的代码，通过过滤器来定位特定用户。这帮助我解决了问题。

try {
        String jsonResponse;

        URL url = new URL("https://onesignal.com/api/v1/notifications");
        HttpURLConnection con = (HttpURLConnection)url.openConnection();
        con.setUseCaches(false);
        con.setDoOutput(true);
        con.setDoInput(true);

        con.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        con.setRequestProperty("Authorization", "Basic ZWY0YTU2YTItMjUzMC00NGY3LThiNTQtODFiY2U1NjQ5NmZj");
        con.setRequestMethod("POST");


        //////////////////////////////// --> Apply Search Criteria Filters Here <-- /////////////////////////
        String strJsonBody = "{"
                +   "\"app_id\": \"5eb5a37e-b458-11e3-ac11-000c2940e62c\","
                +   "\"filters\": [{\"field\": \"tag\", \"key\": \"" + himID + "\", \"relation\": \"=\", \"value\": " +
                "\"himID\"},{\"operator\": \"OR\"},{\"field\": \"amount_spent\", \"relation\": \">\",\"value\": \"0\"}],"
                +   "\"data\": {\"foo\": \"bar\"},"
                +   "\"contents\": {\"en\": \"One Signal Notification Test\"}"
                + "}";
        ///////////////////////////////////////////////////////////////////////////////////////////////////

        Log.d("Query Check->","  Query Check-> jsonResponse:\n" + strJsonBody);

        byte[] sendBytes = strJsonBody.getBytes("UTF-8");
        con.setFixedLengthStreamingMode(sendBytes.length);

        OutputStream outputStream = con.getOutputStream();
        outputStream.write(sendBytes);

        int httpResponse = con.getResponseCode();
        System.out.println("httpResponse: " + httpResponse);

        if (  httpResponse >= HttpURLConnection.HTTP_OK
                && httpResponse < HttpURLConnection.HTTP_BAD_REQUEST) {
            Scanner scanner = new Scanner(con.getInputStream(), "UTF-8");
            jsonResponse = scanner.useDelimiter("\A").hasNext() ? scanner.next() : "";
            scanner.close();
        }
        else {
            Scanner scanner = new Scanner(con.getErrorStream(), "UTF-8");
            jsonResponse = scanner.useDelimiter("\A").hasNext() ? scanner.next() : "";
            scanner.close();
        }
        Log.d("Query Check->","  Query Check-> jsonResponse:\n" + jsonResponse);

    } catch(Throwable t) {
        t.printStackTrace();
    }

使用Java代码：- 其中userId是receiver

的唯一注册id

try {
                        OneSignal.postNotification(new JSONObject("{'contents': {'en': '"+ msg_welcome +"'}, 'include_player_ids': ['" + userId + "']}"),
                                new OneSignal.PostNotificationResponseHandler() {
                                    @Override
                                    public void onSuccess(JSONObject response) {
                                        Log.i("OneSignalExample", "postNotification Success: " + response.toString());

                                    }

                                    @Override
                                    public void onFailure(JSONObject response) {
                                        Log.e("OneSignalExample", "postNotification Failure: " + response.toString());
                                    }
                                });
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

使用PHP：- 其中 $device_id 是 receiver

的唯一注册 ID

<?PHP
function sendMessage($device_id,$msg_title,$msg_body,$msg_img){
    $content = array(
      "en" => $msg_body
      );
     $heading = array(
      "en" => $msg_title
      );
//  $device_id = "da2e72a0-6af7-4102-819e-4b7db5XXXXXX";
    $include_player_id = array(
        $device_id
      );

    $fields = array(
      'app_id' => "YOUR_APP_ID",
      'contents' => $content,
      'headings' => $heading,
      'data' => array("foo" => "bar"),
      'small_icon'=> "ic_launcher",
      'large_icon'=> "ic_launcher",
      'big_picture'=> $msg_img,
      'include_player_ids' => $include_player_id 

      );

    $fields = json_encode($fields);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://onesignal.com/api/v1/notifications");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json',
                           'Authorization: Basic YOUR_REST_API_KEY'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, FALSE);
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

    $response = curl_exec($ch);
    curl_close($ch);

    return $response;
  }

   $response = sendMessage();
    $return["allresponses"] = $response;
    $return = json_encode( $return);

  print("\n\nJSON received:\n");
    print($return);
  print("\n");
?>

thanks got it working , now I just need to figure out how to target a specific user . – Ali Lal Din

关于如何定位特定用户，您可以删除 included_segments 属性并改为发送 include_player_ids。
