Simulation of loopback session

Currently, I am utilizing loopback in conjunction with express session to store cartId.

However, for the purpose of making my tests function properly, it is essential that I inject cartId into the request session.

Within my remote method, I have implemented:

Cart.get = function (req, cb) {
    Service.getCart(req, req.session.cartId)
    .then(function (result) {
        cb(null, result);
    })
    .catch(cb);
};

Cart.remoteMethod(
    'get',
    {
        accepts: { arg: 'req', type: 'object', 'http': { source: 'req' } },
        returns: { arg: 'cart', type: 'object', root: true },
        http: { path: '/', verb: 'get' }
    }
);

I am seeking a way to enforce req.session.cartId for my tests. Any insights on this matter would be greatly appreciated.

Thank you.

Answer №1

After reviewing your scenario, you may implement a similar approach as shown in the code snippet below, with the addition of another parameter (cardId) to the get method definition:

 Cart.remoteMethod('get',{
      accepts: [
        { arg: "caseId", type: "number", http: {source:'path'} },
        { arg: 'req', type: 'object', http: { source: 'req' } }
      ],
      returns: { arg: 'cart', type: 'object', root: true },
      http: { path: '/:caseId/getCart', verb: 'get' }
    });

Answer №2

To easily fetch data, you can utilize the "get" remote method and transmit the cartId via URL. If there are concerns regarding the visibility of cartId in the URL, an alternative is to use the post method as illustrated in the code snippet below. Refer to the cart.js file provided and experiment with it within loopback api.

module.exports = function (Cart) {

  Cart.getCart = function (cartId, cb) { 
    Cart.findOne({
        where: { cartId  :  cartId } 
    }, function (err, cart) { 
      cb(null, users);
    });
  };

 Cart.remoteMethod('getCart', {
    accepts: {
      arg: "id",
      type: "string",
      required: true
    },
    returns: {
      arg: 'cart',
      type: 'object'
    },
    http: {
      path: '/:cartId/getcart',
      verb: 'get'
    }
  });

};

get call : http://HOST:IP/cart/YourID/getcart

By following this approach, you will successfully retrieve the cart based on its Id. Give it a try and see if it meets your requirements.
