dialogflow-go-client's Issues

Return parameters order

When you create a client you return error then the client.

Feels very odd compared to all the other libraries I've used.

	err, client := NewDialogFlowClient(Options{
		AccessToken: "<API.AI TOKEN GOES HERE>",
	})

help me!! To use function EntitiesCreateRequest

If you use Japanese for Entries of EntityCreateRequest, garbled characters will occur, but are there any findings?
If lang is not set in the specification of dialogflow, it says that the default language will be used, but do you know something?

func NewV4() (UUID, error) return 2 values

So in this line:

dialogflow-go-client/apiai.go

Line 47 in 84d8aa0

client.sessionID = uuid.NewV4().String()

should be
u,_ := uuid.NewV4()
client.sessionID = u.String()

Integer in Result.parameters Error

With action entity @sys.number dialogflow returns integer to parameters json and parsing json to string array cause error.

Error
json: cannot unmarshal string into Go struct field Result.parameters of type []string

SessionID is binded to client

I'm just wondering should sessionID be independent of the client?

For example, if I want to get the context of a user, each user should have a different sessionID, but in order to get the context of the user, I have to call SetSessionID so that client.GetSessionID() will return the sessionID of the particular user which is a bit weird.

If I am using it wrong, please tell me how it should be used, thanks 😄

json: cannot unmarshal object into Go value of type []models.IntentAgent

When I try to use

	intents, err := client.IntentsFindAllRequest()
	if err != nil {
		log.Fatal(err)
	}
	for _, intent := range intents {
		fmt.Println(intent.Name)
	}

I got

json: cannot unmarshal object into Go value of type []models.IntentAgent

Even I didn't make any request yet, any hint?

Cannot register an intent

Go get : multiple-value uuid.NewV4() in single-value context

Hi,

I have some trouble go-getting your client using Golang version 1.9.2. Here is the error message :

$ go get -u github.com/mlabouardy/dialogflow-go-client
# github.com/mlabouardy/dialogflow-go-client
../../mlabouardy/dialogflow-go-client/apiai.go:47:32: multiple-value uuid.NewV4() in single-value context

For now, I just want to test dialogflow with my own chat server so I will build the query myself. But if I find some time during the next week I'll try to figure out what's going wrong.
