使用Bing Maps REST控件查找附近的实体

Question

我正在尝试使用Bing Maps REST API来查询给定名称下给定搜索半径内所有实体的地址。最终目标是做一些类似星巴克在这里做的事情:商店定位器，但我使用的是Fiddler，看起来他们正在使用6.3 API:/

如果有办法做到这一点，这似乎是非常糟糕的文档。如果你上传自己的数据，有一些例子可以说明如何做到这一点，但如果你正在搜索应该已经在地图上的本地企业，就不需要这样做:例子。以下是我到目前为止所做的尝试……星巴克，俄勒冈:

var query = 'starbucks';
_map.getCredentials(function (credentials) {
    $.getJSON('http://dev.virtualearth.net/REST/V1/Locations/' + query + '?key=' + credentials + '&lat=' + position.coords.latitude + '&long=' + position.coords.longitude + '&limit=25&jsonp=?&s=1',
    function (result) {
        if (result.resourceSets[0].address != 'undefined') {
            var address = result.resourceSets[0].address;
            alert(address);
        }
        else {
            $("#results").html("Oops! It appears one or more of the addresses you entered are incorrect. :( ");
        }
    });
});

这是位置查询之前的代码，如果你想知道我在位置查询中使用的位置数据是什么-它本质上是从用户的位置通过geolocation API:

var _map;
$(document).ready(function () {
    if (Modernizr.geolocation) {
        $(".geofallback").hide();
    }
    else {
        $(".geofallback").show();
    }
    $.post("Home/Key", { "func": "Key" }, function (data) {
        // Create a Bing map
        _map = new Microsoft.Maps.Map(document.getElementById("map"),
            { credentials: data, mapTypeId: Microsoft.Maps.MapTypeId.ordnanceSurvey });
    });
    // Get the current position from the browser
    if (!navigator.geolocation) {
        $("#results").html("This browser doesn't support geolocation, please enter an address");
    }
    else {
        navigator.geolocation.getCurrentPosition(onPositionReady, onError);
    }
});
function onPositionReady(position) {
    // Apply the position to the map
    var location = new Microsoft.Maps.Location(position.coords.latitude,
            position.coords.longitude);
    _map.setView({ zoom: 18, center: location });
    // Add a pushpin to the map representing the current location
    var pin = new Microsoft.Maps.Pushpin(location);
    _map.entities.push(pin); 
var query = 'starbucks';
    _map.getCredentials(function (credentials) {
        $.getJSON('http://dev.virtualearth.net/REST/V1/Locations/' + query + '?key=' + credentials + '&lat=' + position.coords.latitude + '&long=' + position.coords.longitude + '&limit=25&jsonp=?&s=1',
        function (result) {
            if (result.resourceSets[0].address != 'undefined') {
                var address = result.resourceSets[0].address;
                alert(address);
            }
            else {
                $("#results").html("Oops! It appears one or more of the addresses you entered are incorrect. :( ");
            }
        });
    });
}

任何帮助将非常感激!!

Answer 1

必应地图位置API用于地理编码-即在地图上查找地址或地点。你要做的是找到的东西，然后把它们放在地图上。为此，您需要使用必应API(而不是必应地图API)。

Bing电话簿搜索REST服务应该能满足你的需求——这里有一个例子:http://msdn.microsoft.com/en-us/library/dd251030.aspx来自电话簿搜索的每个结果都有一个Latitude和Longitude属性，您可以使用该属性在地图上创建图钉。

谢谢Alastair -工作完美!下面是代码的工作示例，其中大部分代码略微改编自Alastair链接给我的微软代码:http://msdn.microsoft.com/en-us/library/dd251030.aspx。

这是在MVC3使用Bing地图API与Bing地址簿API的背景下，所以其他代码是用于调整地图到用户的地理位置，然后这是用来找到最近的x数字(每次搜索最多25个结果)，无论你在寻找什么-在这种情况下，咖啡!!

$。文章("Home/GetBingMapsKey",…和美元。文章("Home/GetBingKey",…都在ASP的上下文中。. NET mvc控制器，简单地返回键…并不是说它使密钥安全，因为不幸的是没有办法使用REST API在头中传递密钥…
