这是我的URL构建器：

private const string _googleUri = "http://maps.googleapis.com/maps/api/geocode/xml?address=";
    private const string _googleClientId = "XXXXXXXX";
    private const string _googleSignature = "XXXXXXXXXXXXXXXXXXXXXXXX";
 
//RESOLVED
    private static String GetGeocodeUri(string address)
    {
        ASCIIEncoding encoding = new ASCIIEncoding();
        string url = String.Format("{0}{1}&client={2}&sensor=false",_googleUri,HttpUtility.UrlEncode(address),_googleClientId);
 
        // converting key to bytes will throw an exception,need to replace '-' and '_' characters first.
        string usablePrivateKey = _googleSignature.Replace("-","+").Replace("_","/");
        byte[] privateKeyBytes = Convert.FromBase64String(usablePrivateKey);
 
        Uri uri = new Uri(url);
        byte[] encodedPathAndQueryBytes = encoding.GetBytes( uri.LocalPath + uri.Query );
 
        // compute the hash
        HMACSHA1 algorithm = new HMACSHA1(privateKeyBytes);
        byte[] hash = algorithm.ComputeHash(encodedPathAndQueryBytes);
 
        // convert the bytes to string and make url-safe by replacing '+' and '/' characters
        string signature = Convert.ToBase64String(hash).Replace("+","-").Replace("/","_");
 
        // Add the signature to the existing URI.
        return uri.Scheme + "://" + uri.Host + uri.LocalPath + uri.Query + "&signature=" + signature;
 
    }

这是该计划：

public static AddressClass GetResponseAddress(string address)
    {
        AddressClass GoogleAddress = new AddressClass();
        XmlDocument doc = new XmlDocument();
        String myUri = GetGeocodeUri(address);
 
        try
        {
            doc.Load(myUri);
            XmlNode root = doc.DocumentElement;
            if (root.SelectSingleNode("/GeocodeResponse/status").InnerText == "OK")
            {
                GoogleAddress.Latitude = Double.Parse(root.SelectSingleNode("/GeocodeResponse/result/geometry/location/lat").InnerText);
                GoogleAddress.Longitude = Double.Parse(root.SelectSingleNode("/GeocodeResponse/result/geometry/location/lat").InnerText);
 
            }
         }
         catch (Exception ex)
         {
            Console.WriteLine("Exception <" + ex.Message + ">");
 
         }           
 
        return GoogleAddress;
    }

现在,我对它不起作用的最初反应是Google必须错过引用域,因为它们必须注册.所以我尝试使用HttpWebRequest并将引用设置为我的域,但仍然没有骰子.

//Not needed,Just an alternate method
public static AddressClass GetResponseAddress(string address)
    {
        AddressClass GoogleAddress = new AddressClass();
        WebClient client = new WebClient();
        XmlDocument doc = new XmlDocument();
        Uri myUri = new Uri(GetGeocodeUri(address));
        HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(myUri);
        myRequest.Referer = "http://www.myDomain.com/";
 
        //I've even tried pretending to be Chrome
        //myRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.7 (KHTML,like Gecko) Chrome/16.0.912.75 Safari/535.7";
 
        try
        {
            doc.Load(myRequest.GetResponse().GetResponseStream());
            XmlNode root = doc.DocumentElement;
            if (root.SelectSingleNode("/GeocodeResponse/status").InnerText == "OK")
            {
                GoogleAddress.Latitude = Double.Parse(root.SelectSingleNode("/GeocodeResponse/result/geometry/location/lat").InnerText);
                GoogleAddress.Longitude = Double.Parse(root.SelectSingleNode("/GeocodeResponse/result/geometry/location/lat").InnerText);
            }
         }
         catch (Exception ex)
         {
              Console.WriteLine("Exception <" + ex.Message + ">");
 
         }
 
        return GoogleAddress;
    }

任何帮助将非常感激.
