XPathDocument代理名称无法解析 [英] XPathDocument The proxy name could not be resolved

问题描述

我编写了一个C#程序来从Web服务器读取XML文件.

在某些服务器上，我收到错误消息无法解析代理名称:NAME".这里有一个代理服务器，但是已被删除.错误中显示的代理服务器名称是旧的代理服务器.

如何解决这个问题.该程序作为本地系统"帐户作为服务运行.在IExplorer中未设置代理.

I wrote a C# program to read a XML file from a webserver.

On some servers I receive an error "The proxy name could not be resolved: NAME" There was a proxy server here but that is removed. The proxy servername that is displayed in the error is the old proxy server.

How to resolve this. The program runs as a service as "local System" account. In it IExplorer no proxy is setup.

XmlTextReader xmlReader = new xmlTextReader "http://www.server.eu/some.xml");
xmlReader.XmlResolver = null;
doc = new XPathDocument(xmlReader);
nav = doc.CreateNavigator();

Any ideas?

推荐答案

您需要先使用HTTPWebRequest或WebClient检索xml文件，然后才能对其进行解析.

You need to retrieve the xml file with HTTPWebRequest or WebClient before you can parse it.

像这样重建它:

xtr =新的XmlTextReader(GetStreamForUri("http://www.server.eu/some.xml"，路径，代理));
XPathDocument MyXMLDocument =新的XPathDocument(xtr);
导航= MyXMLDocument.CreateNavigator();

私有Stream GetStreamForUri(字符串待命，字符串路径，字符串代理)
{
WebRequest req = WebRequest.Create(bestand);
如果(proxy！=")
{
字符串uid =测试";
字符串pw =测试";
字符串贫困者= oIni.ReadValue("Proxy"，"Poort"，");
WebProxy myProxy =新的WebProxy(
"HTTP://" +代理+:" +穷人，true)；
req.Proxy = myProxy;
myProxy.Credentials =新的NetworkCredential(
uid，pw，"domain.local")；
}
HttpWebResponse resp =(HttpWebResponse)req.GetResponse();
返回req.GetResponse().GetResponseStream();
}


但是仍然是相同的错误.

Rebuild it like this:

xtr = new XmlTextReader(GetStreamForUri("http://www.server.eu/some.xml", path, proxy));
XPathDocument MyXMLDocument = new XPathDocument(xtr);
nav = MyXMLDocument.CreateNavigator();

private Stream GetStreamForUri(string bestand, string path, string proxy)
{
WebRequest req = WebRequest.Create(bestand);
if (proxy != "")
{
string uid = "Test";
string pw = "Test";
string poort = oIni.ReadValue("Proxy", "Poort", "");
WebProxy myProxy = new WebProxy(
"HTTP://" + proxy + ":" + poort, true);
req.Proxy = myProxy;
myProxy.Credentials = new NetworkCredential(
uid, pw, "domain.local");
}
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
return req.GetResponse().GetResponseStream();
}


But still the same error.
