我试图提取 formatted_address 属性失败。
以下 Web 服务将以下 JSON 记录到控制台。我无法使用returnedData.d.results[0].formatted_address.
$.ajax({
type: "POST",
url: "ReportIncident.aspx/ReverseGeocode",
data: "{latitude:" + latitude + ",longitude:" + longitude + "}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (returnedData)
{
console.log(returnedData);
}
});
json 的格式与Google的格式完全相同。
编辑 达林指出我自相矛盾：网络服务将上面链接中的所有内容都包含在广告对象中，我没有提到这一点。
进一步编辑 这里是网络服务：
[WebMethod]
public static string ReverseGeocode(decimal latitude, decimal longitude)
{
// Create the web request
string url = "http://maps.googleapis.com/maps/api/geocode/json?latlng=" + latitude + "," + longitude +"&sensor=true";
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
// Get response
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
// Get the response stream
StreamReader reader = new StreamReader(response.GetResponseStream());
return reader.ReadToEnd();
}
}
这是javascript：
/Gets the current location of the user
function getLocation()
{
if (navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(showPosition);
}
}
function showPosition(position)
{
var latitude = position.coords.latitude;
var longitude = position.coords.longitude;
$.ajax({
type: "POST",
url: "ReportIncident.aspx/ReverseGeocode",
data: "{latitude:" + latitude + ",longitude:" + longitude + "}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (returnedData)
{
alert(returnedData.d[0].results[0].formatted_address);
console.log(returnedData);
}
});
