C# 如何修复此错误调用google location to address Service“;目标机器主动拒绝了它”;
当试图呼叫Google location to address服务时,它会给我以下消息:C# 如何修复此错误调用google location to address Service“;目标机器主动拒绝了它”;,c#,asp.net,xml,web-services,google-api,C#,Asp.net,Xml,Web Services,Google Api,当试图呼叫Google location to address服务时,它会给我以下消息: 无法建立连接,因为目标计算机处于活动状态 拒绝173.194.66.95:80 我将ASP.net 4与C#一起使用。 这是我的代码: protected void btn_FindAddress_Click(object sender, EventArgs e) { url = "http://maps.googleapis.com/maps/api/geocode/xml?latlng=";
无法建立连接,因为目标计算机处于活动状态 拒绝173.194.66.95:80 我将ASP.net 4与C#一起使用。
这是我的代码:
protected void btn_FindAddress_Click(object sender, EventArgs e)
{
url = "http://maps.googleapis.com/maps/api/geocode/xml?latlng=";
query = LatY.Text + "," + LongX.Text + "&sensor=true";
Address.Text = url;
Uri uri = new Uri (url + query);
// Create a request for the URL.
WebRequest request = WebRequest.Create(uri);
//// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
Status.Text = (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
Address.Text = responseFromServer;
// Clean up the streams and the response.
reader.Close();
response.Close();
}
最常见的情况是,可以建立出站连接(可以访问远程服务器并及时发送响应),但您尝试使用的端口被阻止(防火墙或代理是我能想到的两个最可能的选项) 这也可能源于连接的另一端没有服务器的事实:例如,如果您将端口80 NAT到没有web服务器的系统,则可能会发生这种情况。因为你在调用谷歌的url,我怀疑这是真的,但我认为值得指出
