javascript - console.log(JSON.parse(result)) 在我期望看到 JSON 的地方打印 [Object]

Question

给定一个看似有效的 JSON 格式的字符串(从 api 调用接收)，我如何解析该字符串以便可以访问

JSON.parse(data) 的值返回为包含 [Object] 的 JSON，这对我没有帮助。
我正在尝试从以字符串形式发送给我的数据中获取纬度和经度，我认为可以将其转换为 JSON。
我知道我可以将 data 作为字符串来使用，但我想将其用作 JSON。

{ results: 
   [ { address_components: [Object],
       formatted_address: 'Google Bldg 41, 1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA',
       geometry: [Object],
       place_id: 'ChIJxQvW8wK6j4AR3ukttGy3w2s',
       types: [Object] } ],
  status: 'OK' }

这是数据的值(value):

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "Google Building 41",
               "short_name" : "Google Bldg 41",
               "types" : [ "premise" ]
            },
            {
               "long_name" : "1600",
               "short_name" : "1600",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "Amphitheatre Parkway",
               "short_name" : "Amphitheatre Pkwy",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Mountain View",
               "short_name" : "Mountain View",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Santa Clara County",
               "short_name" : "Santa Clara County",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "California",
               "short_name" : "CA",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {

您可以像这样获取纬度和经度:

parsedData = JSON.parse(data);
lat = parsedData.results[0].geometry.location.lat;
lng = parsedData.results[0].geometry.location.lng;
