php - Google Places API网络服务(PHP): how to get 'administrative_area_2 place_id' for a given 'place_id'

我的Web应用程序收到用户选择的地理位置的place_id。例如:如果用户在前端选择了place called "Comacchio"(这是一个城镇，一部分为Administrative_area_level_2的一部分，称为Province of Ferrara)，则我的网络应用会获取Comacchio的place_id:ChIJ0yHebbB1fkcR7YujotES0dA。

当我在maps.googleapis.com中查询所述place_id时，我得到了很多信息(请参阅下文)，但不是我需要的信息:我需要的是输入place_id(即ChIJ7y4rEyxCfkcRwH-6_AubBwM)的Administrative_area_level_2 的place_id。 (Provincia di Ferrara)。

如下所示，Provincia di Ferrara以字符串形式返回，但不是我需要的place_id。

最佳答案

您可以尝试通过PHP使用选定位置的Administrative_area_level_2(向查询参数添加国家/地区，以获得更准确的预测)值从PHP调用Google Places API Web服务，例如:

https://maps.googleapis.com/maps/api/place/autocomplete/json?input=Provincia%20di%20Ferrara,%20Italy&types=(regions)&language=pt_BR&key={private_key_removed}

输出应为:

{
   "predictions" : [
      {
         "description" : "Provincia di Ferrara, Itália",
         "id" : "b5fa0282b59be22bd0ad64f97011f744db1aeed8",
         "matched_substrings" : [
            {
               "length" : 20,
               "offset" : 0
            }
         ],
         "place_id" : "ChIJ7y4rEyxCfkcRwH-6_AubBwM",
         "reference" : "CkQ1AAAAqCcMPeJiVWhf2mlBLCJVf82WAxOUARNWqT6NWbp7AEb2nlub1ax3iUMDTKsCAvM_Y6Uylc78mSB_QB5bECVkGxIQxCwIgZ4_WC6fAPJB_N7o0RoU8m_Sdb6CpSyaZeW2lpi9YoJ8bO0",

               "value" : "Provincia di Ferrara"
            },
            {
               "offset" : 22,
               "value" : "Itália"
            }
         ],
