OneSignal可以通过应用程序发送通知吗？-Java 学习之路

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功能 .

我有2个应用程序，首先是客户，第二个是卖家 . 我的两个应用都使用差异包名称（com.myapp.customer和com.myapp.seller）

我注册了onesignal并测试推送通知 . 它运作良好 .

现在我将应用程序安装到移动设备并尝试从客户应用程序向卖家应用程序发送通知（两个应用程序安装在同一设备中）但它不起作用 .

我的问题是，是否可以从客户应用程序向卖家应用程序发送通知？如果是这样，怎么做 .

谢谢 .

我认为你应该使用一个信号REST API，并从你的客户应用程序发送请求到他们的服务器 . more info

这是发送推送通知的java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");
?>

Note: 在上面的代码中替换您的卖家应用ID和授权密钥！
