Answer 1

看起来您需要在客户端javascript中访问该文件。你需要使用ajax：以下是jQuery的示例：

$.ajax({
url: 'http://maps.googleapis.com/maps/api/directions/json?origin=41.90119000000001,-87.62979000000001&destination=34.052360,-118.243560&sensor=false&units=metric&language=en-US',
success: function(resultDocuement){   alert(resultDocuement);         },
dataType: 'json'
});

'resultDocuement'将包含json

中URL的结果

首先你没有得到一个xml，你有一个json文件，无论如何你可以用这个来保存你的json文件：

    var client = new WebClient();
    client.Headers.Add("User-Agent", "Nobody");
    var response = client.DownloadString(new Uri("http://maps.googleapis.com/maps/api/directions/json?origin=41.90119000000001,-87.62979000000001&destination=34.052360,-118.243560&sensor=false&units=metric&language=en-US"));
    File.WriteAllText(@"c:\logs\yourjson.json", response.ToString());
