我试图从Python中的Dialogflow中获得每个意图的训练短语的概述。
我按照这个例子生成了以下代码：

from google.cloud import dialogflow_v2

# get_credentials is a custom function that loads the credentials
credentials, project_id = get_credentials()

client = dialogflow_v2.IntentsClient(credentials=credentials)

request = dialogflow_v2.ListIntentsRequest(
    parent=f"projects/{project_id}/agent/environments/draft",
)
page_result = client.list_intents(request=request)

for intent in page_result:
    print("Intent name: ", intent.name)
    print("Intent display_name: ", intent.display_name)
    print("Training phrases: ", intent.training_phrases)

Intent的名称和显示名称按预期打印，但培训短语始终是空列表（对于草稿和测试环境）。为什么我看不到我在控制台中可以看到的训练短语？

编辑在hkanjih的回答之后，我更新了我的代码如下：

from google.cloud import dialogflow_v2

# get_credentials is a custom function that loads the credentials
credentials, project_id = get_credentials()

client = dialogflow_v2.IntentsClient(credentials=credentials)

request = dialogflow_v2.ListIntentsRequest(
    parent=f"projects/{project_id}/agent/environments/draft",
)
page_result = client.list_intents(request=request)

for intent in page_result:
    print("Intent name: ", intent.name)
    # intent.name is equal to projects/{project_id}/agent/intents/{intent_id}
    intent_request = dialogflow_v2.GetIntentRequest(
        name=intent.name,
    )
    intent = client.get_intent(request=intent_request)
    
    # printing intent name again just to check if it's the same (it is)
    print("Intent name: ", intent.name)
    print("Intent display_name: ", intent.display_name)
    print("Training phrases: ", intent.training_phrases)

不幸的是，无论如何：Training phrases: []
