Setting a proxy server in plugin

(0) ShareShare

Posted on by Mir Hassan Ali 1,720

Hi  

I am trying to access a webservice  through plugin and it works fine until I try to set a proxy server. I am using the following code to set the proxy

 

     //Create the SOAP binding for call

            BasicHttpBinding binding = new BasicHttpBinding();

            binding.Security.Mode = BasicHttpSecurityMode.Transport;           

            binding.UseDefaultWebProxy = false;

            binding.ProxyAddress = new Uri(proxyServerUrl);

            soapclient = new SoapClient(binding, new EndpointAddress(new Uri(serviceUrl)));

 

This works fine with my test client and uses the proxy and gets data from service, but when deployed as plugin it throws an exception. This is CRM Online and plugin running under sandbox mode.

 

System.Security.SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Is there anyway proxy can be set?

Thanks

    Hi Hassan,

    Which version are you using? CRM Online or On-premise, CRM Online do not support for accessing third parties, in fact it is limitation of CRM Online, if you want to access from CRM Online, you have use Azure server, first you have to register Azure and host your service in Azure server.

    If you are using CRM Onpremise, register your plugin with None mode, do not use Isoliation mode,

    If it still cannot access, please try to use friendly name of your service do not use IP address.

    Please check this line for Crm Online Limitation https://xrmcenter.wordpress.com/2016/03/31/microsoft-dynamic-crm-limitation/ 

    Regards,

    Hi Mir,

    Sandbox plugin has limitations.

    (proxyServerUrl) the server you are calling is an url or an ip address?

    msdn.microsoft.com/.../gg334752.aspx (see Web access)

    If my response helps you, please mark it as "Verified"

    Best Regards,

    Abhishek
