尝试使用Dialogflow V2 API中的自定义事件更新intent参数，并且不传递给intent

Question

In our Dialogflow agent, We have an intent set up with an event called "updateParams" associated with the intent. The intent has a parameter called "ExampleEntity" that I would like to update using c# by invoking the event using the Detect Intent API. We are using this version of the sdk Google.Cloud.Dialogflow.V2" Version="1.0.0-beta02"

            queryInput.Event = new EventInput
            {
                Name = "updateParams",

                Parameters = new Struct
                {                        
                    Fields = {{ "ExampleEntity",Value.ForString("Bla")}} 
                },
                LanguageCode = languageCode
            };

An example of the response can be seen here. As you can see the "ExampleEntity" parameter isn't being updated as per the request:

Any tips on where we're going wrong? We're fairly new to Dialogflow so it is probably something simple.

Answer 1

Your code looks okay.
However, in your intent, you need to provide default value of the entity ExampleEntity .

Give it as : #event_name.entity_name
Your event is updateParams and entity name is ExampleEntity , so in this case default value will be #updateParams.ExampleEntity

This way, when your intent is invoked through the event with the values passed, ExampleEntity will know from where to pick up the default value.
