Is there any way to introspect messages? about mailgun-go HOT 6 CLOSED

I also have a similar scenario where I want to be able to test whether a message is created with the right information by my application e.g. from, to, subject, body etc. The problem is that all fields are private and can't be accessed by the test function. Using reflection might work, but it would more straightforward if getter functions were provided.

@thrawn01 it sounds too easy not to do 😏

Here's my workaround to introspect the headers field in case it's useful for anyone:

func (mmg *MockMailGun) getHeaderViaReflection(message *mailgun.Message, headerKey string) (string, error) {

    val := reflect.ValueOf(*message)
    headers := val.FieldByName("headers")

    switch headers.Kind() {
    case reflect.Map:
        for _, key := range headers.MapKeys() {
            mapVal := headers.MapIndex(key)
            switch mapVal.Kind() {
            case reflect.String:
                return fmt.Sprintf("%s", mapVal), nil
            default:
                return "error", fmt.Errorf("Unexpected type for value at key: %s", headerKey)
            }
        }

    default:
        return "error", fmt.Errorf("Unexpected type for mailgun message headers field")
    }

    return "error", fmt.Errorf("Did not find headerKey")

}

Sorry for the long response time.

Glad you figured out how to get the information you needed.

Could this have been solved easier at the HTTP level?

@thrawn01 is this more easy now with the mock API you've made? Should this be implemented?

We could expose the headers via a GetHeaders() call. I think that would do the trick.
