c# - 无法使用谷歌通过反向地理编码检索街道、城市和国家/地区对于澳大利亚地址

Question

我确实需要从给定地址中提取街道名称、邮政编码、城市、州、国家、纬度和经度

它适用于印度地址，当我尝试澳大利亚地址时，它无法检索街道名称和邮政编码，其余的东西都可以从 JSON 数组中的地址组件检索约束

我使用了谷歌开发者论坛中引用的以下代码

public void FrmGoogleGeoCode(string frmAddress)
{
        string addUrl = "http://maps.google.com/maps/api/geocode/json?address='" + frmAddress + "'&sensor=false";
      var result = new System.Net.WebClient().DownloadString(addUrl);
      GoogleGeoCodeResponse test = JsonConvert.DeserializeObject<GoogleGeoCodeResponse>(result);
      var response = test.results.First();  
}

在 var 结果中，我得到了地址组件和格式化地址的 JSON 数组 从地址组件中，我需要从澳大利亚地址中检索街道名称、城市、州、邮政编码和国家/地区

请解封此问题

提前致谢

Answer 1

感谢您的回复，我尝试了相同的地址，即 300 George Street, Sydney NSW 2000, Australia 但回复是地址中没有元素

frmAddress ="300 George Street, Sydney NSW 2000, Australia";

这是我的以下代码，用于检索街道名称、城市、郊区、国家/地区、邮政编码

        string addUrl = "http://maps.google.com/maps/api/geocode/json?address='" + frmAddress + "'&sensor=false";
      var result = new System.Net.WebClient().DownloadString(addUrl);
      GoogleGeoCodeResponse test = JsonConvert.DeserializeObject<GoogleGeoCodeResponse>(result);
      var response = test.results.First();
      string route=null;
      string locality=null;
      string pstlCode = null;
      for (int i = 0; i < response.address_components.Count(); i++)
      {
          int j = 0;
          var components = response.address_components[i];
          string type = components.types[j].ToString();
          if (type == "route")
          {
              route = response.address_components[i].long_name.ToString();

          }
          if (type == "locality")
          {
           locality = response.address_components[i].long_name.ToString();
          }
          if (type == "postal_code")
          {
           pstlCode = response.address_components[i].long_name.ToString();
          }
      }
      frmLocation = route +","+locality +","+ pstlCode;

然后我用这段代码尝试了 George Street, Sydney, NSW,2000, Australia。

这是以下回应。请你能不能只发布代码，这样它会对我有很大帮助。
