我正在尝试向我的黑莓应用程序发送推送消息。黑莓通过

php

服务器端代码成功接收消息。然而，我在c#服务器端代码上挣扎了很长一段时间。以下是我正在运行的代码：

string userName = "<appID>";
    string userPW = "<password>";
    public static void SetBasicAuthHeader(WebRequest req, String userName, String userPassword)
    {
        string authInfo = userName + ":" + userPassword;
        authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
        req.Headers["Authorization"] = "Basic " + authInfo;
    }

    public static void SetProxy(WebRequest req)
    {
        Uri newUri = new Uri("http://cp(AppID).pushapi.eval.blackberry.com");
        WebProxy proxy = new WebProxy();
        proxy.Address = newUri;
        proxy.Credentials = new NetworkCredential("<appID>", "<password>");

        req.Proxy = proxy;
    }

        HttpWReq.Method = ("POST");
        HttpWReq.Accept = "text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2";

        //HttpWReq.Credentials = new NetworkCredential(userName, userPW);

        HttpWReq.PreAuthenticate = true;
        HttpWReq.ContentType = "multipart/related; boundary=" + BOUNDARY + "; type=application/xml";

        SetBasicAuthHeader(HttpWReq, userName, userPW);

        StringBuilder dataToSend = new StringBuilder();

        {
            HttpWRes.Close();

        return true;
    }

应用的凭据或URL是否存在任何问题？请帮忙

奇怪的是，为什么要注释掉代码中的HttpsWReq.Credentials=new NetowrkCredential（“用户名”、“密码”）部分

try-catch语句正在执行HttpWReq.GetRequestStream（）；尽管一切看起来都在那里。另一个问题可能是调用SetProxy的强制转换和方法参数。应为WebRequest类型

HttpWReq=（HttpWebRequest）WebRequest.Create（url）

您是什么时候申请凭证的（EVAL/Production？

我设法解决了这个问题。上面代码中的主要问题是构建

Http

请求

WebRequest tRequest;
tRequest = WebRequest.Create(httpURL);
tRequest.Method = "POST";
tRequest.Credentials = new NetworkCredential(appid, password);

另一个需要处理的重要事项是通过上述

NetworkCredentials

发出请求时发生的

Http响应401

。要处理此问题，在发出请求时应调用以下方法：

public static void SetBasicAuthHeader(WebRequest req, String appID, String userPassword)
    {
        string authInfo = appID + ":" + userPassword;
        authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
        req.Headers["Authorization"] = "Basic " + authInfo;
    }

5天前我申请了凭据。它们是评估凭据。我正在调试我的代码，因此注释掉了HttpsWReq.credentials=new NetowrkCredential（“用户名”、“密码”）
仅用于测试目的。有或没有这行代码，结果都是一样的。有帮助吗？是的，我设法解决了这个问题。我将在下面为面临相同问题的任何人发布我的最终代码。是的，我确实删除了SetProxy方法。如果它解决了问题，您可以接受自己的答案。这将让我们知道这个问题不需要更多的帮助。
