Magento 2: Get details of shopping cart all items, subtotal, grand total, billing and shipping address.

We can fetch details of all shopping cart items, subtotal and billing/shipping address from the current session.
Create Block file, ShoppingCart.php

namespace Rbj\Customer\Block;

class ShoppingCart extends \Magento\Framework\View\Element\Template
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Checkout\Model\Session $checkoutSession,
        array $data = []
    ) {
        $this->_checkoutSession = $checkoutSession;;
        parent::__construct($context, $data);

     * Get quote object associated with cart. By default it is current customer session quote
     * @return \Magento\Quote\Model\Quote
    public function getQuoteData()
        if (!$this->hasData('quote')) {
            $this->setData('quote', $this->_checkoutSession->getQuote());
        return $this->_getData('quote');

Call in template(.phtml) file, 

// Get all visible
$quote = $block->getQuoteData();

foreach($quote->getAllVisibleItems() as $_item) {
    //echo "<pre>";print_r($_item->debug());
    echo 'ID: '.$_item->getProductId().'<br/>';
    echo 'Name: '.$_item->getName().'<br/>';
    echo 'Sku: '.$_item->getSku().'<br/>';
    echo 'Quantity: '.$_item->getQty().'<br/>';
    echo 'Price: '.$_item->getPrice().'<br/>';
    echo 'Product Type: '.$_item->getProductType().'<br/>';
    echo 'Discount: '.$_item->getDiscountAmount();echo "<br/>";
    echo "<br/>";
// Get total items and total quantity in current cart
echo $totalItems = $quote->getItemsCount();echo "<br/>";
echo $totalQuantity = $quote->getItemsQty();echo "<br/>";

//Get subtotal and grand total of customer current cart
echo $subTotal = $quote->getSubtotal();echo "<br/>";
echo $grandTotal = $quote->getGrandTotal();echo "<br/>";

//Get billing and shipping addresses of current cart
$billingAddress = $quote->getBillingAddress();
echo "<pre>";print_r($billingAddress->getData());
$shippingAddress = $quote->getShippingAddress();
echo "<pre>";print_r($billingAddress->getData());

call function getQuoteData() and based on that we can get getAllVisibleItems() of cart.

Using getAllVisibleItems() we can get all the visible items data. For configurable product only main item data will be available, Child item data will be not display in for loop using getAllVisibleItems method.

If you want to get all the items, like for a configurable product, the main item with child item data, will be displayed if you use $quote->getAllItems() function. getAllItems() returns all the quote item data.
