黑莓推送通知投掷400错误请求 - 协议错误 [英] Blackberry Push Notifications throwing 400 Bad Request - Protocol Error

问题描述

我正在尝试使用BES的邮政服务向BlackBerry设备发送推送通知。



代码是这样的：



System.Net.WebRequest req = System.Net.WebRequest.Create（ConfigurationManager.AppSettings [BESURL] + userEmailID +

&PORT =+ ConfigurationManager.AppSettings [BBAPPID] +&REQUESTURI = /）;



List<标题和GT;标题=新列表<标题>（）;

标题title =新标题（）;

title.title = sampleString;

标题。添加（标题）;



string st = JsonConvert.SerializeObject（标题）;



req.Method =POST;

req.ContentType =application / json;

byte [] sentData = Encoding.UTF8.GetBytes（st）;

req.ContentLength = sentData.Length;

using（System.IO.Stream sendStream = req.GetRequestStream（））

{

sendStream.Write（sentData，0，sentData.Length）;

sendStream.Close（）;

}

System.Net.WebResponse res = req.GetResponse（）;



如果我使用具有相关有效负载的POSTMAN客户端发送相同请求，则可以正常工作。



有人可以帮忙吗？

解决方案

这似乎是发出POST请求的问题。我有同样的问题并解决了它如下
 
 1）将WebRequest转换为HttpWebRequest  
 HttpWebRequest req =（HttpWebRequest）System.Net.WebRequest.Create（ConfigurationManager） .AppSettings [BESURL] + userEmailID + 
& PORT =+ ConfigurationManager.AppSettings [BBAPPID] +& REQUESTURI = /）; 
 
 2）使用凭据属性向请求发送凭据 
 req.Credentials = CredentialCache.DefaultCredentials; 
 
 3）将Expect100Continue标头设置为false 
  req.ServicePoint.Expect100Continue = false

Hi,

I am trying to send a push notification to BlackBerry devices using the BES's post service.

The Code is something like this:

System.Net.WebRequest req = System.Net.WebRequest.Create(ConfigurationManager.AppSettings["BESURL"] + userEmailID +
"&PORT=" + ConfigurationManager.AppSettings["BBAPPID"] + "&REQUESTURI=/");

List<Titles> Titles = new List<Titles>();
Titles title = new Titles();
title.title = sampleString;
Titles.Add(title);

string st = JsonConvert.SerializeObject(Titles);

req.Method = "POST";
req.ContentType = "application/json";
byte[] sentData = Encoding.UTF8.GetBytes(st);
req.ContentLength = sentData.Length;
using (System.IO.Stream sendStream = req.GetRequestStream())
{
sendStream.Write(sentData, 0, sentData.Length);
sendStream.Close();
}
System.Net.WebResponse res = req.GetResponse();

If I send the Same Request using the POSTMAN client with relevant Payload, it works.

Can someone please help?

解决方案

This seems to be an issue with making POST request. I had the same problem and solved it as below

1) Convert WebRequest to HttpWebRequest
HttpWebRequest req = (HttpWebRequest)System.Net.WebRequest.Create(ConfigurationManager.AppSettings["BESURL"] + userEmailID +
 "&PORT=" + ConfigurationManager.AppSettings["BBAPPID"] + "&REQUESTURI=/");
  
2) Send credentials to the request using Credentials property
    req.Credentials = CredentialCache.DefaultCredentials;

3) Set Expect100Continue header to false
   req.ServicePoint.Expect100Continue = false
   More info about this header:

Hope this solves your issue.
