請原諒我的無知，但經過幾個小時的搜索後，我運氣不佳。使用Google位置API
無論如何，我正在嘗試編寫一個小型桌面應用程序，允許用戶輸入一個地址，然後在GPS座標中返回其大致位置。從我可以告訴，谷歌提供了一個地理編碼API [1]，允許在下列形式要求：
http://maps.googleapis.com/maps/api/geocode/output?parameters
雖然我熟悉編寫基本的C夏普的應用，我真的不知道在哪裏當涉及到與這個API的接口時開始。任何幫助，你們可以提供將不勝感激。
Geocode API非常簡單，只需要3個參數即輸出，傳感器和地址就可以獲得緯度/經度。
輸出所需的輸出格式，JSON或XML（這個）
傳感器應該是一個布爾值，指示天氣或不值來自一個傳感器，諸如GPS芯片。
地址應該是您希望進行地理編碼的地址（不要忘記對其進行網址編碼）。
這是一個例子，在那裏我地理編碼我的辦公地址，並響應得到JSON： http://maps.googleapis.com/maps/api/geocode/json?sensor=false&address=1+Maritime+Plaza+San+Francisco+CA
如果您導航到你應該看到類似：
{
"status": "OK",
"results": [ {
"types": [ "street_address" ],
"formatted_address": "1 Maritime Plaza, San Francisco, CA 94111, USA",
"address_components": [ {
"long_name": "1",
"short_name": "1",
"types": [ "street_number" ]
}, {
"long_name": "Maritime Plaza",
"short_name": "Maritime Plaza",
"types": [ "route" ]
}, {
"long_name": "San Francisco",
"short_name": "San Francisco",
"types": [ "locality", "political" ]
}, {
"long_name": "San Francisco",
"short_name": "San Francisco",
"types": [ "administrative_area_level_3", "political" ]
}, {
"long_name": "San Francisco",
"short_name": "San Francisco",
"types": [ "administrative_area_level_2", "political" ]
}, {
"long_name": "California",
"short_name": "CA",
"types": [ "administrative_area_level_1", "political" ]
}, {
"long_name": "United States",
"short_name": "US",
"types": [ "country", "political" ]
}, {
"long_name": "94111",
"short_name": "94111",
"types": [ "postal_code" ]
} ],
"geometry": {
"location": {
"lat": 37.7953907,
"lng": -122.3991803
},
"location_type": "ROOFTOP",
"viewport": {
"southwest": {
"lat": 37.7922431,
"lng": -122.4023279
},
"northeast": {
"lat": 37.7985383,
"lng": -122.3960327
}
}
}
} ]
}
如果拿提供緯度/經度，並將其放置在map上，您可以在辦公樓看到指針。
如果你在C＃中這樣做，你會希望使用HttpWebRequest和HttpWebResponse類。您可以將參數化的URL（Google API調用）作爲參數傳遞給Create（）方法。我建議請求將數據作爲XML數據返回。關閉連接（httpWResp.Close（））後，您可以使用流讀取器進行讀取。上看到的GetResponseStream（）方法文檔：http://msdn.microsoft.com/en-us/library/system.net.httpwebresponse.getresponsestream.aspx
HttpWebRequest的HttpWReq = （HttpWebRequest的）WebRequest.Create（「http://maps.googleapis.com/maps/api/geocode/xml?sensor=false &地址= 1 + Maritime + Plaza + San + Francisco + CA 「）;
HttpWebResponse HttpWResp =（HttpWebResponse）HttpWReq.GetResponse（）; //插入使用響應對象的代碼。 HttpWResp。關（）;
下面是一個簡單的代碼來獲得你想要的東西
using System;
using System.Web;
using System.Net;
using System.Runtime.Serialization.Json;
namespace GoogleMapsSample
{
public class GoogleMaps
{
/// <summary>
///
/// </summary>
/// <param name="address"></param>
/// <returns></returns>
public static GeoResponse GetGeoCodedResults(string address)
{
string url = string.Format(
"http://maps.google.com/maps/api/geocode/json?address={0}®ion=dk&sensor=false",
HttpUtility.UrlEncode(address)
);
var request = (HttpWebRequest)HttpWebRequest.Create(url);
request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip,deflate");
request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(GeoResponse));
var res = (GeoResponse)serializer.ReadObject(request.GetResponse().GetResponseStream());
return res;
}
}
和您的輔助類是
namespace GoogleMapsSample
{
[DataContract]
public class GeoResponse
{
[DataMember(Name = "status")]
public string Status { get; set; }
[DataMember(Name = "results")]
public CResult[] Results { get; set; }
[DataContract]
public class CResult
{
[DataMember(Name = "geometry")]
public CGeometry Geometry { get; set; }
[DataContract]
public class CGeometry
{
[DataMember(Name = "location")]
public CLocation Location { get; set; }
[DataContract]
public class CLocation
{
[DataMember(Name = "lat")]
public double Lat { get; set; }
[DataMember(Name = "lng")]
public double Lng { get; set; }
}
}
}
public GeoResponse()
{ }
}
}
然後你就可以在你的控制使用此代碼/像這樣
的WinForms GeoResponse response = new GeoResponse();
response = GoogleMaps.GetGeoCodedResults(TextBoxPostcode.Text);
並在代碼背後使用StringBuilder或其他任何構建JS代碼
完全記錄.NET庫 -
爲.NET https://github.com/maximn/google-maps/
//Directions
DirectionsRequest directionsRequest = new DirectionsRequest()
{
Origin = "NYC, 5th and 39",
Destination = "Philladephia, Chesnut and Wallnut",
};
DirectionsResponse directions = MapsAPI.GetDirections(directionsRequest);
//Geocode
GeocodingRequest geocodeRequest = new GeocodingRequest()
{
Address = "new york city",
};
GeocodingResponse geocode = MapsAPI.GetGeocode(geocodeRequest);
Console.WriteLine(geocode);
//Elevation
ElevationRequest elevationRequest = new ElevationRequest()
{
Locations = new Location[] { new Location(54, 78) },
};
ElevationResponse elevation = MapsAPI.GetElevation(elevationRequest);
Console.WriteLine(elevation);
最近，我必須建立一個商店定位爲一個項目我工作的谷歌地圖的Web服務API的包裝。我以前從未使用任何Google或Bing API。使用本教程，我能夠很好地掌握Location API。我會建議閱讀本教程，並在三篇教程結束時，您應該有一個很好的理解。

通過使用GuigleAPI nuget，你可以簡單地做：
GoogleGeocodingAPI.GoogleAPIKey = "YOUR API KEY";
var result = await GoogleGeocodingAPI.GetCoordinatesFromAddressAsync("100 Market St, Southbank");
var latitude = result.Item1;
var longitude = result.Item2;
只需用的NuGet命令安裝，包裝Easyforce.GuigleAPI並安裝它你很好 走。

我一定會嘗試了這一點。在此期間，我只想說謝謝，我真的很感激。 – 2011-01-28 18:16:52
如果添加可選的區域參數，它將盡力在該位置返回一個位置。 – 2012-03-15 14:10:01
