淘宝IP地址库:http://ip.taobao.com,里面有REST API 说明。
Delphi XE 调试通过,关键代码如下:
[delphi] view plaincopy
- var
- IdHTTP: TIdHTTP;
- RequestURL: string;
- ResponseStream: TStringStream;
- JO, JData: TJSONObject;
- begin
- IdHTTP := TIdHTTP.Create(nil);
- IdHTTP.ReadTimeout := 0;
- IdHTTP.AllowCookies := True;
- IdHTTP.ProxyParams.BasicAuthentication := False;
- IdHTTP.ProxyParams.ProxyPort := 0;
- IdHTTP.Request.ContentLength := -1;
- IdHTTP.Request.ContentRangeEnd := 0;
- IdHTTP.Request.ContentRangeStart := 0;
- IdHTTP.Request.ContentType := ‘application/x-www-form-urlencoded‘;
- IdHTTP.Request.Accept := ‘text/html, */*‘;
- IdHTTP.Request.BasicAuthentication := False;
- IdHTTP.Request.UserAgent := ‘Mozilla/3.0 (compatible; Indy Library)‘;
- IdHTTP.HTTPOptions := [hoForceEncodeParams];
- RequestURL := ‘http://ip.taobao.com/service/getIpInfo.php?ip=‘ + edtIP.Text;
- ResponseStream := TStringStream.Create;
- IdHTTP.Get(RequestURL, ResponseStream);
- IdHTTP.Free;
- ResponseStream.Position := 0;
- Memo1.Text := ResponseStream.DataString;
- ResponseStream.Position := 0;
- JO := TJSONObject.ParseJSONValue(ResponseStream.DataString) as TJSONObject;
- JData := JO.Get(‘data‘).JsonValue as TJSONObject;
- leISP.Text := (JData.Get(‘isp‘).JsonValue as TJSONString).Value;
- leCountry.Text := (JData.Get(‘country‘).JsonValue as TJSONString).Value;
- leArea.Text := (JData.Get(‘area‘).JsonValue as TJSONString).Value;
- leRegion.Text := (JData.Get(‘region‘).JsonValue as TJSONString).Value;
- leCity.Text := (JData.Get(‘city‘).JsonValue as TJSONString).Value;
- JO.Free;
- ResponseStream.Free;
- end;
