(C# UWP/WinRT) REST through HTTP Proxy

Demonstrates how to connect through an HTTP proxy to make REST API calls.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example connects to a REST server through an HTTP proxy.
// It will connect to the Amazon AWS service for this example.
Chilkat.Rest rest = new Chilkat.Rest();
Chilkat.Socket socket = new Chilkat.Socket();

// Set the HTTP proxy domain or IP address, and port.
socket.HttpProxyHostname = "192.168.1.100";
socket.HttpProxyPort = 8088;

// We want to tell the socket object that we're doing HTTP over the proxy connection.
// This is because an HTTP proxy used for other protocols (IMAP, SMTP, SSH, FTP, etc.) 
// can require some internal differences in behavior (i.e. how we do things).
socket.HttpProxyForHttp = true;

// Other properties exist for specifying a proxy login, password, and authentication method (such as NTLM),
// but these are not used in this example.

// Connect through the HTTP proxy to the Amazon AWS server for the S3 service.
bool bTls = true;
int port = 443;
int maxWaitMs = 5000;
bool success = await socket.ConnectAsync("s3.amazonaws.com",port,bTls,maxWaitMs);
if (success != true) {
    Debug.WriteLine("Connect Failure Error Code: " + Convert.ToString(socket.ConnectFailReason));
    Debug.WriteLine(socket.LastErrorText);
    return;
}

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

// Provide AWS credentials for the REST call.
Chilkat.AuthAws authAws = new Chilkat.AuthAws();
authAws.AccessKey = "AWS_ACCESS_KEY";
authAws.SecretKey = "AWS_SECRET_KEY";
authAws.ServiceName = "s3";
success = rest.SetAuthAws(authAws);

// List all buckets for the account...
string responseXml = await rest.FullRequestNoBodyAsync("GET","/");
if (rest.LastMethodSuccess != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

Chilkat.Xml xml = new Chilkat.Xml();
success = xml.LoadXml(responseXml);

// Show the full XML returned.
Debug.WriteLine(xml.GetXml());

// Iterate over the buckets, showing each bucket name.
success = xml.FindChild2("Buckets");
if (xml.FirstChild2() == true) {
    Debug.WriteLine(xml.GetChildContent("Name"));
    while ((xml.NextSibling2() == true)) {
        Debug.WriteLine(xml.GetChildContent("Name"));
    }

}

// Move the internal pointer back to the root node.
