WebResponse动态“有时”崩溃

Question

我有一个foreach和一个"If"，当条件为真时，我做一个WebResponse来在服务器中发布我的项目。

有时，代码会运行两个o多个项，但其他情况下会出现以下错误：

远程服务器返回一个错误：(407)代理身份验证。

守则：

WebClient client = new WebClient();

                string authInfo = "admin:geoserver";
                string address = "http://xxxxxxxx:8080/geoserver/rest/workspaces/";
                client.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(authInfo));



                WebRequest request = WebRequest.Create(address);

                request.ContentType = "text/xml";
                request.Method = "POST";

                request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(authInfo));

                byte[] bret = Encoding.GetEncoding("UTF-8").GetBytes("<workspace><name>" + nameWS + "</name></workspace>");



                Stream reqstr = request.GetRequestStream();
                reqstr.Write(bret, 0, bret.Length);
                reqstr.Close();


                try
                {
                    WebResponse response = request.GetResponse();

                    response.Close();

                }

我的环境是C# Visual 2010

你多久叫一次？正如其他人所建议的那样，服务器可能受到DOS的保护，而您的请求就是这样。例如，用一个使用块立即释放所有一次性对象也是很有价值的。我们曾经有过一些问题，因为在我们的网络中，有太多的连接可以打开到我们的web服务器。您可以将代码调整为如下所示：

using(var client = new WebClient())
{
    string authInfo = "admin:geoserver";
    string address = "http://xxxxxxxx:8080/geoserver/rest/workspaces/";
    client.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(authInfo));

    var request = WebRequest.Create(address);

    request.ContentType = "text/xml";
    request.Method = "POST";

    request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(authInfo));

    byte[] bret = Encoding.GetEncoding("UTF-8").GetBytes("<workspace><name>" + nameWS + "</name></workspace>");

    using (var reqstr = request.GetRequestStream())
    {
        reqstr.Write(bret, 0, bret.Length);
    }

    try
    {
        using (var response = request.GetResponse())
        {
            // your code here...
        }

    }
    catch (Exception exc)
    {
        System.Diagnostics.Debug.WriteLine(exc.Message);
    }
}
