Access SOAP fr .NET MVC Controller w/ Static IP

    Note: This example assumes your QUOTAGUARD_URL environment variable is set and contains your unique connection string.

    Here we show how to use QuotaGuard to access a SOAP service from a .NET MVC web controller. This example should also apply to other WebRequests made from an MVC controller.

    A common use case is from your MVC controller you want to access an IP-whitelisted service that uses SOAP but the web service object does not have a “proxy” property that allows you to specify the QuotaGuard proxy service.

    Solution: Create a proxy object and use it as a property of the WebRequest MVC class, which will send all following requests via the proxy.

    The solution is split in to two parts, the configuration in your web.config (which on Azure can be done from your management console) and the MVC Controller itself.

    MVC Controller

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.Mvc;
    using Bank.Webservices; // fictitious namespace name for your webservice's reference
    using System.Diagnostics;
    using System.Xml;
    using System.Net;
    using System.Web.Configuration;
    
    public class PaymentController : Controller
    {
    [HttpPost]
    // this is usually a form result, so attribute of action is HttpPost
    public ActionResult Index(string anyTokenYouUseWithYourBank)
    {
    string QuotaGuardProxyAddress = WebConfigurationManager.AppSettings["QuotaGuard_Proxy_URI"];
    // to get the Proxy Uri from Web.config
    
    string QuotaGuardUser = WebConfigurationManager.AppSettings["QuotaGuard_User"];
    // to get the Proxy User from Web.config
    
    string QuotaGuardPassword = WebConfigurationManager.AppSettings["QuotaGuard_Password"];
    // to get the Proxy Password from Web.config
    
    var proxy = new WebProxy(QuotaGuardProxyAddress);
    // we create a new proxy object
    
    proxy.Credentials = new NetworkCredential(QuotaGuardUser, QuotaGuardPassword);
    // we give the proxy the QuotaGuard credentials
    
    WebRequest.DefaultWebProxy = proxy;
    // thanks to WebRequest, from here on every request of this controller will pass through the proxy
    
    var soapClientObject = new WSBankSoapClient(); //fictitious name for the banks's web service
    
    var result = soapClientObject .GrabSomethingOnTheNet(anyTokenYouUseWithYourBank);
    // now our WS call goes passes Proxy and in the variable result we have the web service's result
    
    // we use the result here 
    
    return Redirect("http://newpage");
    
    }
    }
    

    Configuration (web.config)

    <!-- keys for QuotaGuard-->
    <add key="QuotaGuard_Proxy_URI" value="http://yourQuotaGuardUser:yourQuotaGuardPassword@eu-west-1-babbage.getstatica.io:9293"/>
    <add key="QuotaGuard_User" value="yourQuotaGuardUser"/>
    <add key="QuotaGuard_Password" value="yourQuotaGuardPassword"/>
    <!-- end of keys for QuotaGuard-->
    ...
    </appSettings>
