HERE Places API:并非所有商品都有PVID

Question

我正在使用HERE Places API.

首先,我正在进行搜索.

例如此查询:

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

根据这个文档(链接)如果我添加show_refs=pvid到查询字符串,结果我将获得外部id,我可以用来查询lookup端点.

但结果我得到了下一个回复:

在回应没有对象 references

这是一个bug还是不是每个地方都有这个外部ID？

Answer 1

我作为 HERE Places API 团队的成员做出回应。

是的，不是每个地方都有pvid。这就是为什么我建议使用共享 ID。我意识到应该改进文档来澄清这一点。

show_refs=sharing可以通过添加到您的搜索查询或地点详细信息请求来获取共享 ID 。它可以在现场找到references。获得共享 ID 后，您就可以按照预期查找端点。
