api - 这里地方 API : not all items have PVID

Question

我正在使用 HERE Places API。

首先我在做一个搜索。

例如这个查询:

https://places.cit.api.here.com/places/v1/discover/search?q=Test&at=35.6111,-97.5467&r=500&size=1&app_id=DemoAppId01082013GAL&app_code=AJKnXv84fjrb0KIHawS0Tg&show_refs=pvid&pretty

根据此文档( Link )如果我添加 show_refs=pvid查询字符串，结果我会得到外部 id我可以用它来查询 lookup端点。

但结果我得到了下一个回应:

        "next": "https://places.cit.api.here.com/places/v1/discover/search;context=Zmxvdy1pZD1hY2ExNzk3NC0zYzg3LTU5NzQtYmZkMC04YjAzMDZlYWIzMWJfMTUwNjA3NjMzMTYyMl83NDY3XzM4NTAmb2Zmc2V0PTEmc2l6ZT0x?at=35.6111%2C-97.5467&q=Test&app_id=DemoAppId01082013GAL&app_code=AJKnXv84fjrb0KIHawS0Tg",

在回应没有对象 references
这是一个错误还是不是每个地方都有这个外部ID？

Answer 1

我是作为 HERE Places API 团队成员的回应。

是的，不是每个地方都有 pvid。这就是我建议改用共享 ID 的原因。我意识到应该改进文档以澄清这一点。

可以通过添加 show_refs=sharing 获得共享 ID。您的 search query或 place details request .可在字段 references 中找到.获得共享 ID 后，您就可以像您一样使用查找端点 intended .
