Telerik 推送通知过滤

Question

我正在开发一个系统，该系统会在系统中发布新项目时自动发送推送消息。这很顺利。问题是我必须对软件包和专业进行一些过滤。

在第一个过滤器块中，它可以工作，但它会发送到所有符合其中一个条件的设备。我想要的（并在测试 2 和 3 中尝试过）是它只在有人拥有软件包和某个职业时发送。

telerik api 的愚蠢之处在于它只是 returns 一个 HTTP 400，所以调试非常困难

希望有人能帮助我。

ps。我在片段

中跳过了一些不相关的 code/functions

function sendNotifications(some parameters)
{
    string json = "{";
    //Test code 1 - This works
    json += "\"Filter\": {";
    json += "\"Parameters.softwarePakket\": {\"$in\": [ \"{software_package}\"]},";
    json += "\"Parameters.beroepsGroep\": {\"$in\": [\"{profession1}\", \"{profession2}\"]},";
    json += "\"Parameters.module\": {\"$in\": [\"{module}\"]}},";

    //Test code 2 - This doesn't work
    //json += "\"Filter\": {\"$and\":[{\"Parameters.softwarePakket\":\"{software_package}\"},{\"Parameters.beroepsGroep\":\"{profession1}\"}]}";

    //Test code 3 - And this doesn't work either
    //json += "\"Filter\": \"{\"$and\":[{\"Parameters.softwarePakket\":\"{software_package}\"},{\"Parameters.beroepsGroep\":\"{profession1}\"}]}\"";

    //From here its all fine
    json += "\"Android\": {\"data\": {\"title\": \"{app_title}\",\"message\": \"{message}\",\"color\": \"#ffffff\",\"largeIcon\": \"{icon}\",\"customData\": \"{type}\"}},";
    json += "\"IOS\": {\"aps\": {\"alert\": \"{message}\",\"badge\": \"+1\",\"sound\": \"default\",\"category\": \"{type}\"},\"customData\": \"{type}\"}";
    json += "}";

    json = json.Replace("{type}", type);
    json = json.Replace("{icon}", formatIcon(type));
    json = json.Replace("{message}", genericMessage(type));

    var request = (HttpWebRequest)WebRequest.Create("http://api.everlive.com/v1/{app_id}/Push/Notifications");
    request.Method = "POST";
    request.ContentType = "application/json";
    request.ContentLength = json.Length;
    using (var stream = new StreamWriter(request.GetRequestStream()))
    {
        stream.Write(json);
        stream.Flush();
        stream.Close();
    }

    var response = (HttpWebResponse)request.GetResponse();

    var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
}

我认为您在过滤器字符串的末尾缺少一个逗号。所以代码应该是：

//Test code 2
json += "\"Filter\": {\"$and\":[{\"Parameters.softwarePakket\":\"{software_package}\"},{\"Parameters.beroepsGroep\":\"{profession1}\"}]},";

//Test code 3
//json += "\"Filter\": \"{\"$and\":[{\"Parameters.softwarePakket\":\"{software_package}\"},{\"Parameters.beroepsGroep\":\"{profession1}\"}]}\",";
