(C# UWP/WinRT) Xero API through an SOCKS Proxy

This example demonstrates connecting through a SOCKS proxy w/ 2-legged OAuth for a Xero private application.

This example requires Chilkat v9.5.0.64 or later

// This example requires Chilkat v9.5.0.64 or later

// This sample code would typically be placed in a subroutine or function
// where the rest object is passed by reference.
// It does the OAuth1 setup and makes the initial connection.
Chilkat.Rest rest = new Chilkat.Rest();

// Connect to the Xero server through an HTTP proxy, and then tell the REST object
// to use the socket connection.
Chilkat.Socket socket = new Chilkat.Socket();

// Set the SOCKS proxy domain or IP address, port, and SOCKS version number (4 or 5)
socket.SocksHostname = "192.168.1.100";
socket.SocksPort = 1080;
socket.SocksVersion = 5;
// Other properties exist for specifying a SOCKS proxy login and password,
// but these are not used in this example.

// Connect through the SOCKS proxy..
bool bTls = true;
int port = 443;
int maxWaitMs = 5000;
bool success = await socket.ConnectAsync("api.xero.com",port,bTls,maxWaitMs);
if (success != true) {
    Debug.WriteLine("Connect Failure Error Code: " + Convert.ToString(socket.ConnectFailReason));
    Debug.WriteLine(socket.LastErrorText);
    return;
}

// Use the SOCKS proxied TLS connection:
success = rest.UseConnection(socket,true);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// OK, we're connected.  
// The UseConnection method has an internal reference to the underlying/internal socket.
// The application can does not need to keep its socket object in existence.
// -----------------------------------------------------------------
// Now setup the OAuth1 authenticator..

string consumerKey = "XERO_PRIVATE_APP_KEY";
string consumerSecret = "XERO_PRIVATE_APP_SECRET";

// Let's get our private key from our PFX (password protected), or the PEM (unprotected).
// You can decide which to use.  Either is OK, although I would recommend keeping your
// private keys in a PFX and not in an unprotected PEM.
Chilkat.Pfx pfx = new Chilkat.Pfx();
success = pfx.LoadPfxFile("qa_data/certs/xero_private_app/public_privatekey.pfx","PFX_PASSWORD");

// Note: There are many other means for loading a private key, including
// from other formats and directly from memory (i.e. not file-based).

oauth1.SetRsaKey(privKeyFromPfx);

// Install the OAuth1 authenticator.
rest.SetAuthOAuth1(oauth1,false);

Debug.WriteLine("OK, the Xero OAuth1 is initialized and the REST object is ready to make REST API calls..");

// -----------------------------------------------------------------
// Make a call to verify that OAuth1 through an HTTP proxy works..

// Get the full list of contacts.
Chilkat.StringBuilder sbXml = new Chilkat.StringBuilder();

// Iterate over the contacts..
