我有以下用于从OSM请求地图数据的代码:
$.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,它运行没有任何问题,但是当在JavaScript中执行此请求时,我总是收到错误:

我的请求方式一定有问题,但我无法弄清楚它有什么问题。
如何通过JavaScript获取柏林所有学校的职位?
我也尝试使用$.getJSON()
,但这对我来说也不起作用。

您在示例中使用的网址似乎不完整:它应该显示为... MAKEFILE_GENERATOR = UNIX
TARGET_PLATFORM = unix
TEMPLATE = app
CONFIG += qt warn_on release incremental link_prl gdb_dwarf_index
QT += core gui
QMAKE_INCREMENTAL_STYLE = sublib
include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)
QMAKE_CC = arm-linux-gnueabihf-gcc-4.8
QMAKE_CXX = arm-linux-gnueabihf-g++-4.8
QMAKE_LINK = arm-linux-gnueabihf-g++-4.8
QMAKE_LINK_SHLIB = arm-linux-gnueabihf-g++-4.8
QMAKE_AR = arm-linux-gnueabi-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabi-objcopy
QMAKE_STRIP = arm-linux-gnueabi-strip
load(qt_config)
....即 data = 部分缺失。
作为参考,您还可以将您的查询放在立交桥turbo中,只需点击导出 - &gt;原始数据直接来自Overpass API以获取工作URL。也许首先使用wget尝试这个,如果确定没问题,请将URL放在Javascript代码中。
也许您还想学习一下,如何通过立交桥turbo(基于POST)调用Overpass API:有关详细信息,请参阅https://github.com/tyrasd/overpass-turbo/blob/master/js/overpass.js#L581。
