(Swift 3,4,5...) Shopify Private Authentication for Private Apps

Shopify private authentication is for interacting with your own store through private applications. It uses HTTP "Basic" authentication with your Shopify private application key and secret key.

This example demonstrates how to send a private authenticated request using Chilkat Http, and then the same using Chilkat Rest.

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

    // First demonstrate sending a simple request using Shopify private authentication w/ the Chilkat Http API.
    let http = CkoHttp()!

    // To use HTTP Basic Authentication with any HTTP request, we simply set the Login, Password, and BasicAuth properties.
    // Important: All HTTP requests using Basic authentication must be over SSL/TLS.
    http.login = "SHOPIFY_PRIVATE_API_KEY"
    http.password = "SHOPIFY_PRIVATE_API_SECRET_KEY"
    http.basicAuth = true

    // Make sure to replace "chilkat" with your store name.
    var resp: CkoHttpResponse? = http.quickGetObj("https://chilkat.myshopify.com/admin/products.json")
    if http.lastMethodSuccess != true {
        print("\(http.lastErrorText!)")
        return
    }

    // Examine the response code.
    if resp!.statusCode.intValue != 200 {
        print("Received error response code: \(resp!.statusCode.intValue)")
        print("Response body:")
        print("\(resp!.bodyStr!)")
        resp = nil
        return
    }

    // Success.
    print("Success.")

    // Examine the JSON response 
    let sbJson = CkoStringBuilder()!
    resp!.getBodySb(sbJson)
    resp = nil
    let json = CkoJsonObject()!
    json.loadSb(sbJson)
    json.emitCompact = false
    print("\(json.emit()!)")

    // -------------------------------------------------
    // Now let's do the same using the Chilkat Rest API.
    let rest = CkoRest()!

    // Provide the private app credentials:
    rest.setAuthBasic("SHOPIFY_PRIVATE_API_KEY", password: "SHOPIFY_PRIVATE_API_SECRET_KEY")

    // Connect to the shopify server.
    var bTls: Bool = true
    var port: Int = 443
    var bAutoReconnect: Bool = true
    // Make sure to replace "chilkat" with your store name.
    var success: Bool = rest.connect("chilkat.myshopify.com", port: port, tls: bTls, autoReconnect: bAutoReconnect)
    if success != true {
        print("\(rest.lastErrorText!)")
        return
    }

    sbJson.clear()
    success = rest.fullRequestNoBodySb("GET", uriPath: "/admin/products.json", sb: sbJson)
    if rest.lastMethodSuccess != true {
        print("\(rest.lastErrorText!)")
        return
    }

    if rest.responseStatusCode.intValue != 200 {
        print("Received error response code: \(rest.responseStatusCode.intValue)")
        print("Response body:")
        print("\(sbJson.getAsString()!)")
        return
    }

    // Success...
    json.loadSb(sbJson)
    print("\(json.emit()!)")
