我想用经度和纬度获取地址(城市,邮政编码,街道地址),但我不知道如何。我正在使用Open层,当我点击地图的一部分时,获得该位置的经度和纬度。有人有解决方案吗?

map.on('click', function (evt) {
var coord = ol.proj.toLonLat(evt.coordinate);
alert(coord);

您正在寻找的是#34;反向地理编码&#34;。这里显示了一个很好的示例:https://gist.github.com/ThomasG77/26e61508217ba86a04c19a67cbda0e99
在你的情况下,大致会转化为:
function reverseGeocode(coords) {
fetch('http://nominatim.openstreetmap.org/reverse?format=json&lon=' + coords[0] + '&lat=' + coords[1])
.then(function(response) {
return response.json();
}).then(function(json) {
console.log(json);
});
}
map.on('click', function (evt) {
var coord = ol.proj.toLonLat(evt.coordinate);
reverseGeocode(coord);
});
然后响应与此类似:
