How to setup a complicated 'IsList' parameter in Dialogflow

问题

I'm looking at this link:

Actions and parameters | Dialogflow Documentation | Google Cloud

Where it explains 'List parameters' it uses these examples:

"I want apples"

"I want apples and oranges"

"I want apples, oranges, and bananas"

Then I was wondering if it's possible to set up a 'List parameter' to handle something like this:

"I want 7 apples, 8 oranges and 12 bananas"

So you'd have a sort of Key - Value pair list.

Pseudo code:

List<KeyValuePair<string, int>> fruitList = new List<KeyValuePair<string, int>>();

KeyValuePair<string, int> applesItem = new KeyValuePair<string, int>("apples", 7);
KeyValuePair<string, int> orangesItem = new KeyValuePair<string, int>("oranges", 8);
KeyValuePair<string, int> bananasItem = new KeyValuePair<string, int>("bananas", 12);

fruitList.Add(applesItem);
fruitList.Add(orangesItem);
fruitList.Add(bananasItem);

So, in dialogflow, the $FruitList parameter would be something like the Key - Value pair list fruitList above.

The number part should then match with the @sys.cardinal entity. And the fruit part should match to a custom entity @Fruits with a bunch of fruits in it.

Pseudo code: List<KeyValuePair<@sys.cardinal, @Fruits>>

How can I make an 'Intent' in Dialogflow that can do this? Is it possible?

Help / Advice appreciated.

Im not sure if you could get dialogflow return a key value pair object, but using composite entities you can create an entity which consists of an amount (number) and a fruit (fruit entity). You could call this composite entity order and make that a list in the parameters in your intent. When you enter

"I want 7 apples, 8 oranges and 12 bananas"

You should get a list with 3 order entities ( 7 apples, 8 oranges, 12 bananas)
