OneSignal 可以跨应用发送通知吗?

Can OneSignal send notification across app?

我正在使用 cordova 开发 android 应用程序,我在我的应用程序中包含一个信号通知作为一项功能。

我有 2 个应用程序,第一个用于客户,第二个用于卖家。我的两个应用程序都使用不同的包名称(com.myapp.customer 和 com.myapp.seller)

我注册了一个信号并测试推送通知。效果很好。

现在我将应用程序安装到移动设备上,并尝试从客户应用程序向卖家应用程序发送通知(两个应用程序都安装在同一台设备上),但它不起作用。

我的问题是是否可以从客户应用向卖家应用发送通知?如果可以,怎么做。

谢谢。

我认为您应该使用一个信号 REST API 并从您的客户应用程序向他们的服务器发送请求。 more info

这里是 java 发送推送通知的代码:

    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 NGEwMGZmMjItY2NkNy0xMWUzLTk5ZDUtMDAwYzI5NDBlNjJj");
   con.setRequestMethod("POST");

   String strJsonBody = "{"
                      +   "\"app_id\": \"5eb5a37e-b458-11e3-ac11-000c2940e62c\","
                      +   "\"included_segments\": [\"All\"],"
                      +   "\"data\": {\"foo\": \"bar\"},"
                      +   "\"contents\": {\"en\": \"English Message\"}"
                      + "}";


   System.out.println("strJsonBody:\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();
   }
   System.out.println("jsonResponse:\n" + jsonResponse);

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

php代码:

<?PHP
  function sendMessage(){
    $content = array(
      "en" => 'English Message'
      );

    $fields = array(
      'app_id' => "5eb5a37e-b458-11e3-ac11-000c2940e62c",
      'included_segments' => array('All'),
      'data' => array("foo" => "bar"),
      'contents' => $content
    );

    $fields = json_encode($fields);
    print("\nJSON sent:\n");
    print($fields);

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://onesignal.com/api/v1/notifications");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json',
                           'Authorization: Basic NGEwMGZmMjItY2NkNy0xMWUzLTk5ZDUtMDAwYzI5NDBlNjJj'));
    curl_setopt($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");
?>
