(JavaScript) REST through HTTP Proxy

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

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// 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.
var rest = new CkRest();
var socket = new CkSocket();

// 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.
var bTls = true;
var port = 443;
var maxWaitMs = 5000;
success = socket.Connect("s3.amazonaws.com",port,bTls,maxWaitMs);
if (success !== true) {
    console.log("Connect Failure Error Code: " + socket.ConnectFailReason);
    console.log(socket.LastErrorText);
    return;
}

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

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

// List all buckets for the account...
var responseXml = rest.FullRequestNoBody("GET","/");
if (rest.LastMethodSuccess !== true) {
    console.log(rest.LastErrorText);
    return;
}

var xml = new CkXml();
success = xml.LoadXml(responseXml);

// Show the full XML returned.
console.log(xml.GetXml());

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

}

// Move the internal pointer back to the root node.
xml.GetRoot2();
