循环通过json请求Alexa技能

Question

我似乎遇到了循环浏览我从Alexa技能中的URL中提取的数据的问题，这是我的示例代码：

def get_elevator_status():
session_attributes = {}
card_title = "Septa Elevator Status"
reprompt_text = ""
should_end_session = False


response = urllib2.urlopen(API_BASE_URL + "/elevator")
septa_elevator_status = json.load(response) 


for elevators in septa_elevator_status['results']:
    speech_output = "The following elevators are out of service." "On " + elevators['line'] + " at station " + elevators['station'] + " the " + elevators['elevator'] + " elevator has " + elevators['message']

如果我在python shell中运行代码并打印出结果（如果有多次中断），则打印出所有行。但是，当我测试我的Alexa技能并要求停电时，即使有多次电梯停电，它也只报告一个结果。我错过了一些工作吗？这段代码应该循环通过并说明找到的所有结果吗？

Answer 1

你可以发布'响应'json，我的猜测是json没有正确形成

Answer 2

每当你用特定的speech_output覆盖elevators时，循环遍历结果集。相反，你必须将每个结果连接到speech_output。

for elevators in septa_elevator_status['results']:
    speech_output =  speech_output  + " <s> The following elevators are out of service." "On " + elevators['line'] + " at station " + elevators['station'] + " the " + elevators['elevator'] + " elevator has " + elevators['message'] + "</s>"

<s>是句子标记，只有在使用SSML时才使用它。
