Question

我正在使用文字搜索请求处理Google Place API，我想知道如何过滤特定国家/地区的搜索结果。有办法吗？

我要做的是调用带有按国家/地区过滤的结果的API，然后使用php管理json结果。

所以，这是一种查询

https://maps.googleapis.com/maps/api/place/textsearch/json?query=pizza&sensor=true&key=mykey

我希望添加一个像＆amp; country = us这样的参数，但它似乎不存在。

由于

Answer 1

将国家/地区代码作为选项中componentRestrictions中的参数传递。然后将此选项作为参数传递给google.maps.places.Autocomplete

e.g。

var options = {
  componentRestrictions: {country: 'in'}
};

autocomplete = new google.maps.places.Autocomplete(input, options);

Answer 2

for API : country:in

AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
        .setCountry("IN")
        .build();

Answer 3

我试图找到相同的过滤方法，但最终决定使用geocode api：

https://maps.googleapis.com/maps/api/geocode/json?address=SOME_VALUE&key=YOUR_KEY&language=en&components=country:US

最后一个查询参数components=country:US过滤请求（在我的示例中设置为US）。

希望它可以帮助遇到相同问题的任何人。
