.NET4で、SoapHttpClientProtocolがプロキシ資格情報をキャッシュしているように見えることに気づきました。これが本当かどうか、そしてこのキャッシュを更新する方法を誰かが知っていますか?ユーザーが資格情報を変更した場合、それらを試してみたいのですが、SoapHttpClientProtocolが正常に接続されると、呼び出す呼び出しが機能しているように見えます。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Web.Services;
class Program : System.Web.Services.Protocols.SoapHttpClientProtocol
{
public Program()
{
base.Url = "something";
}
static void Main(string[] args)
{
Program x = new Program();
x.Proxy = new WebProxy("basicproxy", 2121);
x.Proxy.Credentials = new NetworkCredential("proxyuser", "IncorrectPassword");
Console.WriteLine("Attempt with proxyuser and IncorrectPassword: " + x.NoOp());
x.Proxy.Credentials = new NetworkCredential("proxyuser", "password");
Console.WriteLine("Attempt with proxyuser and password: " + x.NoOp());
x.Proxy.Credentials = new NetworkCredential("proxyuser", "IncorrectPassword");
Console.WriteLine("Attempt with proxyuser and IncorrectPassword: " + x.NoOp());
Program y = new Program();
y.Proxy = new WebProxy("basicproxy", 2121);
y.Proxy.Credentials = new NetworkCredential("proxyuser", "IncorrectPassword");
Console.WriteLine("Attempt with proxyuser and IncorrectPassword: " + y.NoOp());
}
/// <remarks/>
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("...", RequestNamespace = "...", ResponseNamespace = "...", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
public bool NoOp()
{
try
{
object[] results = this.Invoke("NoOp", new object[0]);
return ((bool)(results[0]));
}
catch (WebException e)
{
if (e.Response != null && ((HttpWebResponse)e.Response).StatusCode == HttpStatusCode.ProxyAuthenticationRequired)
{
Console.WriteLine("incorrect Credential attempt!");
}
else
{
Console.WriteLine("Exception: " + e.Message);
}
}
return false;
}
このプログラムの出力(最後の2つはfalseであると予想しています)
incorrect Credential attempt!
Attempt with proxyuser and IncorrectPassword: False
Attempt with proxyuser and password: True
Attempt with proxyuser and IncorrectPassword: True
Attempt with proxyuser and IncorrectPassword: True
