我有以下代码用于从OSM请求地图数据:
$.ajax({
url:
'https://www.overpass-api.de/api/interpreter?' +
'[out:json][timeout:60];' +
'area["boundary"~"administrative"]["name"~"Berlin"];' +
'node(area)["amenity"~"school"];' +
'out;',
dataType: 'json',
type: 'GET',
async: true,
crossDomain: true
}).done(function() {
console.log( "second success" );
}).fail(function(error) {
console.log(error);
console.log( "error" );
}).always(function() {
console.log( "complete" );
});
当我在Overpass Turbo上测试请求时,它运行时没有任何问题,但当在JavaScript中预先形成此请求时,我总是会收到错误:

我提出请求的方式肯定有问题,但我想不出有什么问题。
如何通过JavaScript获取柏林所有学校的位置?
我也尝试过使用
$.getJSON()
但这对我也不起作用。
