提示请求消息
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
实现价格 Feed 的方法之一是使用价格更改(以前称为“提取并提示”)。
此方法的流程如下所示:
Google 会从根元素 <HintRequest>
发送提示请求消息,其中包含来自您最近一次服务器更新的时间信息。
您的服务器会响应一个 Hint 回应消息 <Hint>
,其中包含自上次更新以来价格发生变化的酒店列表。
然后,Google 会返回一个查询消息:<Query>
。
您的服务器会响应一个包含更新后数据的交易消息 <Transaction>
。
如需简要了解重新定价,请参阅重新定价流程。
默认情况下,Google 会每隔 5 分钟向您的服务器发送一条提示请求消息。您可以通过与我们联系设置来调整此频率。
请求消息使用 HTTP POST
方法发送,其中 Content-Type
标头设置为 application/xml
,User-Agent
标头设置为 Google-HotelAdsPrices
。请与您的技术支持客户经理 (TAM) 联系,确保 Google 发回的端点状态为 OK
。您应该已在酒店价格初始设置期间配置此设置。
Hint 请求示例
提示请求消息的根元素为 <HintRequest>
,且只有一个子元素 <LastFetchTime>
。
<?xml version="1.0" encoding="UTF-8"?>
<HintRequest id="request" timestamp="2023-06-03T22:59:48Z">
<LastFetchTime>2023-06-03T22:54:40Z</LastFetchTime>
</HintRequest>

Google sends a Hint Request message from the root element [`\u003cHintRequest\u003e`](../xml-reference/queries#hintrequest)\n that contains time information from your most recent server update.\n\n2. Your server responds with a [Hint Response\n message](/hotels/hotel-prices/dev-guide/hint-response-messages), [`\u003cHint\u003e`](../xml-reference/queries#Hint),\n which contains a list of hotels prices that have changed since\n the last update.\n\n3. Google then responds with a\n [Query message](/hotels/hotel-prices/dev-guide/query-messages): [`\u003cQuery\u003e`](../xml-reference/queries#Query).\n\n4. Your server responds with a\n [Transaction message](/hotels/hotel-prices/dev-guide/transaction-overview),\n [`\u003cTransaction\u003e`](../xml-reference/transaction-messages#Transaction), that includes the updated data.\n\nFor an overview of repricing, see [Repricing\nprocess](/hotels/hotel-prices/dev-guide/updating-prices#repricing-process).\n\nGoogle sends a Hint Request message to your server at 5-minute intervals by\ndefault. This frequency can be adjusted by setting [contact us](https://support.google.com/hotelprices/gethelp).\n\nThe request message is sent using an HTTP `POST` method with the `Content-Type`\nheader set to `application/xml` and the `User-Agent` header set to\n`Google-HotelAdsPrices`. Ensure the endpoint status that Google sends back is `OK` by\ncontacting your Technical Account Manager (TAM). You should have configured this setting during your\nHotel Prices initial setup.\n\n### Hint Request example\n\nHint Request messages have a root element of\n[`\u003cHintRequest\u003e`](../xml-reference/queries#hintrequest) and a single child element, `\u003cLastFetchTime\u003e`. \n\n \u003c?xml version=\"1.0\" encoding=\"UTF-8\"?\u003e\n \u003cHintRequest id=\"request\" timestamp=\"2023-06-03T22:59:48Z\"\u003e\n \u003cLastFetchTime\u003e\u003cvar translate=\"no\"\u003e2023-06-03T22:54:40Z\u003c/var\u003e\u003c/LastFetchTime\u003e\n \u003c/HintRequest\u003e\n\nFor more examples and additional information, refer to [Query \\& Hints XML Reference](../xml-reference/queries)."]]
