Question

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。

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。
