Asp.net 中的 GCM 请求

Question

我已将此 link 提交给发送 GCM 请求，它运行良好。 gcm-push-notification-with-asp-net

我又向 link 推荐了一个 post JSON how-to-post-json-to-the-server

在第二个的基础上link我尝试了下面的代码

        var httprequest = (HttpWebRequest)WebRequest.Create("https://gcm-http.googleapis.com/gcm/send");
        httprequest.ContentType = "application/json";
        httprequest.Method = "POST";
        httprequest.Headers.Add(string.Format("Authorization: key={0}", GCM.APIKey));
        httprequest.Headers.Add(string.Format("Sender: id={0}", GCM.ProjectNo));

        using (var streamWriter = new StreamWriter(httprequest.GetRequestStream()))
        {
            string json = new JavaScriptSerializer().Serialize(new GCMValues
            {
                delay_while_idle = false,
                priority = "high",
                registration_id = regId,
                data = new MessagesValues
                {
                    message = message
                }
            });

            streamWriter.Write(json);
            streamWriter.Flush();
            streamWriter.Close();
        }

        var httpResponse = (HttpWebResponse)httprequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
        }

我用过的属性

public class GCMValues
{
    public Object data { get; set; }
    public bool delay_while_idle { get; set; }
    public String priority { get; set; }
    public String registration_id { get; set; }
}
public class MessagesValues
{
    public String message { get; set; }
    public DateTime? time { get; set; }
}

我面临的问题在第 var httpResponse =(HttpWebResponse)httprequest.GetResponse();

行

我收到错误请求的响应。我哪里出错了，或者可以做些什么来为 GCM post 请求传递 JSON 格式的值。提前致谢。

Answer 1

您在 JSON 中需要 registration_ids（复数）而不是 registration_id（单数）。它是一个字符串数组，而不是单个字符串值。

如果您选中 GCM documentation，它会提供所有 JSON 选项。

文档在其他地方详细说明了如何使用 to 如果您只有一个令牌可以向其发送通知，如本例所示：

  {
    "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification" : {
      "body" : "great match!",
      "title" : "Portugal vs. Denmark",
      "icon" : "myicon"
    }
  }

Answer 2

我用了下面的方法，成功了。

var httprequest = (HttpWebRequest)WebRequest.Create("https://gcm-http.googleapis.com/gcm/send");
        httprequest.ContentType = "application/json";
        httprequest.Method = "POST";
        httprequest.Headers.Add(string.Format("Authorization: key={0}", GCM.APIKey));
        httprequest.Headers.Add(string.Format("Sender: id={0}", GCM.ProjectNo));
        String[] regid = regId.Split(',');

        using (var streamWriter = new StreamWriter(httprequest.GetRequestStream()))
        {
            string json = new JavaScriptSerializer().Serialize(new GCMValues
            {
                delay_while_idle = false,
                priority = "high",
                registration_ids = regid,
                data = new MessagesValues
                {
                    message = message
                }
            });

            streamWriter.Write(json);
            streamWriter.Flush();
            streamWriter.Close();
        }

        var httpResponse = (HttpWebResponse)httprequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            if (result.Contains("Error"))
            {
                return false;
            }
        }

我用过的属性

public class GCMValues
{
    public Object data { get; set; }
    public bool delay_while_idle { get; set; }
    public String priority { get; set; }
    public String[] registration_ids { get; set; }
}
public class MessagesValues
{
    public String message { get; set; }
    public DateTime? time { get; set; }
}
