Question

我是Windows Phone开发8.1的新手，我想创建一个文本框，可以使用城市名称（印度）执行自动填写。我试着安装-pack gmaps-api-net 0.13.4它给了我一个错误。

错误是：您正在尝试定位＆＃39; Windows Phone，版本= 8.1但该程序包不包含与该框架兼容的任何程序集引用或内容文件。

谢谢＆amp;问候，考希克。

Answer 1

我认为这个套餐无法正常运行，因为您必须从Google控制台创建浏览器密钥，并按以下方式调用

 string Entrypoint = String.Format("https://maps.googleapis.com/maps/api/place/autocomplete/json?input={0}&types=geocode&sensor=false&key={1}", txtCityName.Text.Trim(), Constant.GOOGLE_KEY);

Answer 2

首先，你需要创建一个如下所示的类，

public static async Task GetResponse（string url） { 尝试 { // CustomLogger.printMsgOnConsole（＆＃34; GetResponse中的Url =＆gt;＆＃34; + url）; //创建客户端 HttpClient client = new HttpClient（）; //CustomLogger.printMsgOnConsole("HttpClient obj created＆＃34; + client）;

            //Define URL. Replace current URL with your URL
            var uri = new Uri(url);
         //   CustomLogger.printMsgOnConsole("Create uri" + uri.ToString());
            //Call. Get response by Async
            var Response = await client.GetAsync(uri);
          //  CustomLogger.printMsgOnConsole("Calling get async");
            //Result & Code
            var statusCode = Response.StatusCode;
          //  CustomLogger.printMsgOnConsole("status code " + statusCode);
            //If Response is not Http 200 
            //then EnsureSuccessStatusCode will throw an exception
            Response.EnsureSuccessStatusCode();

            //Read the content of the response.
            //In here expected response is a string.
            //Accroding to Response you can change the Reading method.
            //like ReadAsStreamAsync etc..
            var ResponseText = await Response.Content.ReadAsStringAsync();

           // CustomLogger.printMsgOnConsole("Reponse in GetResponse =>" + ResponseText);

            return ResponseText;

        }

现在您需要拨打下面的电话，

string myhttp =＆＃34; https://maps.googleapis.com/maps/api/place/autocomplete/json?input=＆＃34; + txtCityName.Text.Trim（）+＆＃34;＆amp; types = geocode＆amp; sensor = false＆amp; key =＆＃34; + mykey;

请注意 1]。 txtCityName是文本框名称。 2]。 mykey是Google Api（网页）生成的密钥。

这将返回json响应。

谢谢，考希克。
