我想从 WCF 休息服务向 Kindle Fire 发送推送通知。
我使用了 PushSharp 库，但它无法正常工作。您能否建议不使用 PushSharp 库的其他方法？
我使用下面的代码在kindle上发送通知，它给出错误400，
private void sendNotification(String registrationID)
{
String message = "{data\": {\"NTY\":\"-1\",\"NOTY\": \"2\"}}";
String title="title";
String accessToken = "";
accessToken = UpdateAccessToken();
HttpWebRequest httpWReq =
(HttpWebRequest)WebRequest.Create("https://api.amazon.com/messaging/registrations/" + registrationID + "/messages");
Encoding encoding = new UTF8Encoding();
string postData = "{\"data\":{\"message\":\"" + message + "\",\"title\":\"" + title + "\"},\"consolidationKey\":\"Some Key\",\"expiresAfter\":86400}";
byte[] data = encoding.GetBytes(postData);
httpWReq.ProtocolVersion = HttpVersion.Version11;
httpWReq.Method = "POST";
httpWReq.ContentType = "application/json";//charset=UTF-8";
httpWReq.Headers.Add("X-Amzn-Type-Version",
"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="13707c7e3d727e72697c7d3d7776657a70763d7e76606072747a7d743d52575e5e76606072747653223d23" rel="noreferrer noopener nofollow">[email protected]</a>");
httpWReq.Headers.Add("X-Amzn-Accept-Type",
"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1774787a39767a766d7879397372617e7472397a72646476707e79703956535a44727973457264627b6357263927" rel="noreferrer noopener nofollow">[email protected]</a>");
httpWReq.Headers.Add(HttpRequestHeader.Authorization,
"Bearer " + accessToken);
httpWReq.ContentLength = data.Length;
Stream stream = httpWReq.GetRequestStream();
stream.Write(data, 0, data.Length);
stream.Close();
HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();
string s = response.ToString();
StreamReader reader = new StreamReader(response.GetResponseStream());
String jsonresponse = "";
String temp = null;
while ((temp = reader.ReadLine()) != null)
{
jsonresponse += temp;
}
}
最佳答案
PushSharp 依赖于 Android 版 Google Cloud Messaging，但 Kindle 不支持该功能。您需要实现 Amazon Device Messaging (ADM) 版本 ( https://developer.amazon.com/public/apis/engage/device-messaging ) 或利用 Amazon 的简单通知服务 (SNS) 来定位 Kindle 和其他平台(https://aws.amazon.com/sns/)
