How to calculate and store shipping rate in Magento 2.3.0?

Question

I'm using Magento v 2.3.0.

I am trying to skip Shipping Address section and navigate directly to Payment section if customer has a default address.

I have overridden below class to change the link of checkout url

Magento\Checkout\Block\Onepage\Link

Function overridden

getCheckoutUrl

Now I also use the checkout session in above overridden class to get the quote and set the shipping address in it.

I use tablerate_bestway as shipping method.

How do I set the shipping method and recalculate the shipping rate and save it in the quote?

Answer 1

After set the shipping address in quote use below code to set shipping method programatically

$shippingAddress = $quote->getShippingAddress();
$shippingAddress->setCollectShippingRates(true)
        ->collectShippingRates()
        ->setShippingMethod('shippingMethod') //shipping method
        ->setShippingDescription('shipping method description'); //shipping description
$quote->save();
