Google maps api 3 如何识别google place details结果是否为状态（管理区域级别1）

目前，我们正在使用Google places api的address_组件数组来识别搜索的地点是州还是国家。对于州和国家地点，我们将在搜索提交时传递州代码和国家代码。以下是我们用于确定地点详细信息结果类型的场景：

状态场景：地址组件有两个项目，第一个项目中有行政区域级别1类型，第二个项目中有国家类型

  "address_components" : [
     {
        "long_name" : "California",
        "short_name" : "CA",
        "types" : [ "administrative_area_level_1", "political" ]
     },
     {
        "long_name" : "United States",
        "short_name" : "US",
        "types" : [ "country", "political" ]
     }
  ],

国家/地区场景：地址\u组件有1项，其类型有国家/地区

  "address_components" : [
     {
        "long_name" : "United States",
        "short_name" : "US",
        "types" : [ "country", "political" ]
     }
  ],

如果address_components项目列表中有两个以上的项目，则所选地点不被视为州或国家。而像“Oaxaca”或“NewYork”这样的搜索很少会返回地址数组中两个以上的项

瓦哈卡：

  "address_components" : [
     {
        "long_name" : "Oaxaca",
        "short_name" : "Oaxaca",
        "types" : [ "locality", "political" ]
     },
     {
        "long_name" : "Oaxaca",
        "short_name" : "Oaxaca",
        "types" : [ "administrative_area_level_2", "political" ]
     },
     {
        "long_name" : "Oaxaca",
        "short_name" : "Oax.",
        "types" : [ "administrative_area_level_1", "political" ]
     },
     {
        "long_name" : "Mexico",
        "short_name" : "MX",
        "types" : [ "country", "political" ]
     }
  ]

纽约

  "address_components" : [
     {
        "long_name" : "New York",
        "short_name" : "New York",
        "types" : [ "locality", "political" ]
     },
     {
        "long_name" : "New York",
        "short_name" : "NY",
        "types" : [ "administrative_area_level_1", "political" ]
     },
     {
        "long_name" : "United States",
        "short_name" : "US",
        "types" : [ "country", "political" ]
     }
  ]

是否有其他方法可以识别搜索地点详细信息结果（如Oaxaca）

是一个状态（管理区域级别1）

当然，您可以使用随地址组件字段一起返回的类型字段

types[]包含描述给定结果的要素类型数组

就国家而言

你会看到类似的东西

我希望这有帮助类型字段，并且该字段表示结果的类型。如果可以从

types

字段中立即知道结果的类型，我不理解为什么需要分析地址组件中的项数。
