Asp. NET get the JSON from the API interface provided by Baidu Map

Idea: The beginning is to get directly in the foreground, but cross-domain access is still a bit difficult, and the format must be JOSNP format, finally too troublesome, forced to give up.

I do the ASP. And this has its own parsing class, direct reference on the line

Get to Josn in the background first:

1 Private voidGetqzyzuobiaotomap (HttpContext context)2         {3             //determine if login is invalid4             if(Context. session["_user"] ==NULL)5             {6Writeresponse (Context,false,"you are not logged in or login is invalid! ");7                 return;8             }9             //define a front-end pass-through string, get to the later can be directly into the Baidu API interface insideTen             stringDialt = context. request["Dialt"]. Trim (); One             //define a string to receive Baidu API interface sent back JOSN A             stringstr =""; -             //WebClient This method is the method that ASP. -             using(WebClient client =NewWebClient ()) the             { -                 //transcoding -Client. Encoding =System.Text.UTF8Encoding.UTF8; -                 //Dialt (String received by the foreground) +str = client. Downloadstring ("http://api.map.baidu.com/geocoder/v2/?address="+ Dialt +"&output=json&ak= here to write your Baidu AK"); -             } +             //return to this josn A context. Response.Write (str); at}

Then write an Ajax in the foreground JS to get this JSON:

//defines a string that can define a text box for user data, or a combo drop-down box    //example 1:var Dialt = $.trim ($ ("#Dialt"). Val ());    //Example 2 var cityname = $ (' #cityName '). ComboBox (' GetText ')    //var provisionname = $ (' #provisionName '). ComboBox (' GetText ')    //var dialt = provisionname + cityname;    //here is the Easyui drop-down box, if defined directly can also    vardialt= "Ju Feng Township, Shiqian County, Tongren Prefecture, Guizhou province"//Longitude    varLNG = ""; //Latitude    varLat = ""; $.ajax ({URL:'/service/userserviceluo.ashx ', type:' Post ', data: {command:"3001032",                    //Pass a string pastDialt:dialt}, DataType:' JSON ', Async:false, Success:function(Result) {LNG= RESULT.RESULT.LOCATION.LNG;//Longitudelat = Result.result.location.lat;//Dimension of}, Error:function(x, MSG, E) {}}); varlongitude = LNG;//Longitude    varLatitude = lat;//Latitude
