Azure ServiceBus - Request a Token from ACS

This example duplicates the HTTP POST described at Request a Token from ACS. Swift

func chilkatTest() {
    var success: Bool = false

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

    // The goal of this example is to send the following HTTP POST:

    // POST https://your-namespace-sb.accesscontrol.windows.net/WRAPv0.9/ HTTP/1.1  
    // Content-Type: application/x-www-form-urlencoded  
    // Host: your-namespace-sb.accesscontrol.windows.net  
    // Content-Length: 136  
    // Expect: 100-continue  
    // Connection: Keep-Alive  
    // 
    // wrap_name=owner&wrap_password=r8LuxCKD6DWY8auQcFql4M7euH2UuhcLcV1TaJTqNNE%3d&wrap_scope=http%3a%2f%2fyour-namespace.servicebus.windows.net%2f
    // 

    let http = CkoHttp()!
    let req = CkoHttpRequest()!

    // Build the HTTP request...
    req.httpVerb = "POST"
    req.path = "/WRAPv0.9/"
    req.contentType = "application/x-www-form-urlencoded"

    // Adding the Connection: Keep-Alive is optional.  It only makes sense if the intent is to send
    // additional requests to the same domain (your-namespace-sb.accesscontrol.windows.net) within a reasonable time period.
    req.addHeader(name: "Connection", value: "Keep-Alive")

    // The Expect: 100-continue really isn't necessary.  This only makes sense when a response is large.  The "100-continue"
    // provides a means for the HTTP server to alert the HTTP client that the request failed before sending the full response.
    // In this case, the response size is small, so there's no real need to bother with an "Expect: 100-continue".
    // If desired, it would be added just like any request header:
    req.addHeader(name: "Expect", value: "100-continue")

    // Note: The following headers are automatically added by Chilkat:  Content-Type, Host, Content-Length.
    // The application should NOT set these directly.

    // Add the query parameters
    // When URL decoded and split, the query params look like this:
    // 
    // 	wrap_name=owner
    // 	wrap_password=r8LuxCKD6DWY8auQcFql4M7euH2UuhcLcV1TaJTqNNE=
    // 	wrap_scope=http://your-namespace.servicebus.windows.net/

    // Pass the URL-decoded values to AddParam.
    req.addParam(name: "wrap_name", value: "owner")
    req.addParam(name: "wrap_password", value: "r8LuxCKD6DWY8auQcFql4M7euH2UuhcLcV1TaJTqNNE=")
    req.addParam(name: "wrap_scope", value: "http://your-namespace.servicebus.windows.net/")

    // OK.. our request is properly setup.  Now send to the web server at your-namespace-sb.accesscontrol.windows.net.
    // We want https (i.e. SSL/TLS), so the port would be 443.
    var useTls: Bool = true
    let resp = CkoHttpResponse()!
    success = http.httpSReq(domain: "your-namespace-sb.accesscontrol.windows.net", port: 443, ssl: useTls, request: req, response: resp)
    if success == false {
        print("\(http.lastErrorText!)")
        return
    }

    // A successful response will have a status code = 200.
    if resp.statusCode.intValue != 200 {
        print("Response Status Code = \(resp.statusCode.intValue)")
        print("\(resp.bodyStr!)")
        print("Failed.")
        return
    }

    // A successful response will contain a URL encoded param string such as the following:

    // 	wrap_access_token=net.windows.servicebus.action%3d
    // 	Listen%252cManage%252cSend%26
    // 	http%253a%252f%252fschemas.microsoft.com%252faccesscontrolservice%252f2010%252f07%252fclaims%252fidentityprovider%3d
    // 	https%253a%252f%252fyour-namespace-sb.accesscontrol.windows.net%252f%26
    // 	Audience%3dhttp%253a%252f%252fyour-namespace.servicebus.windows.net%252f%26
    // 	ExpiresOn%3d1404435127%26
    // 	Issuer%3dhttps%253a%252f%252fyour-namespace-sb.accesscontrol.windows.net%252f%26
    // 	HMACSHA256%3dF%252bBoXUoifWdT%252fly8Oic9V1oPBbc3KmXKbSJbVhGSopU%253d&
    // 	wrap_access_token_expires_in=10799
    // 

    // The UrlEncParamValue method can be used to extract individual param values by name.
    // There are two params in the response: wrap_access_token and wrap_access_token_expires.
    // (It's a bit confusing because the value of the wrap_access_token is itself a URL encoded 
    // param string.)

    // Get the access token from the response:
    var accessToken: String? = resp.urlEncParamValue(encodedParams: resp.bodyStr, paramName: "wrap_access_token")

    print("Your access token is the following param string:")
    print("\(accessToken!)")
