This question is related to an older question:
Is it possible to specify proxy credentials in your web.config?
I created a custom web proxy class and using it in the section as shown in the above question's answer. I have a constructor in the custom web proxy class that accepts the proxy URL, username, password and domain values. However, I couldn't figure out how to have .NET call this parameterized constructor because I am not explicitly creating a web proxy object. I have added the following configuration setting in my web.config file
<system.net>
<defaultProxy enabled="true" useDefaultCredentials="false">
<module type="ISO.Prometrix.CommunityMitigation.Common.Impl.ProxyModule,
ISO.Prometrix.CommunityMitigation.Common"/>
</defaultProxy>
</system.net>
I am using spring.net for DI. I added the object definition for my custom class in my spring config file but when I run the project it seems to always call the default constructor. In order to make this work, I am reading the proxy URI, username, password and domain from the config app settings inside my custom web proxy.
I would like to inject these values into my custom class from outside. Here is my code:
public class ProxyModule : IWebProxy
{
private readonly string _username;
private readonly string _password;
private readonly string _domain;
private readonly string _proxyAddress;
public ProxyModule()
{
// Unable to figure out how to invoke the parameterized constructor on this
// class that's why doing this workaround.
_username = ConfigurationManager.AppSettings["ProxyUsername"];
_password = ConfigurationManager.AppSettings["ProxyPassword"];
_domain = ConfigurationManager.AppSettings["ProxyDomain"];
_proxyAddress = ConfigurationManager.AppSettings["ProxyAddress"];
}
public ProxyModule(
string username,
string password,
string domain,
string proxyAddress)
{
_username = username;
_password = password;
_domain = domain;
_proxyAddress = proxyAddress;
}
public ICredentials Credentials
{
get
{
return new NetworkCredential(_username, _password, _domain);
}
set {}
}
public Uri GetProxy(Uri destination)
{
return new Uri(_proxyAddress);
}
public bool IsBypassed(Uri host)
{
return false;
}
}
