Question

我写了一个非常简单的应用程序（页面上），其中有一个地图，用户可以在其上绘制圆圈。第一个圆圈是Source，下一个圆圈是目的地。我必须对API URL进行Ajax调用，以便获取用户在地图上绘制的圆圈内的所有单元格ID。

这是我到现在为止所尝试的：

<html>
  <head>
    <title>Drawing tools</title>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
    <meta charset="utf-8">

<script type="text/javascript"> 

 var latitude;
 var longitude;
 var radius;

  (function () {
     var circle;

   function initialize() {
    var mapOptions = {
      center: new google.maps.LatLng(-34.397, 150.644),
      zoom: 8
   };

  var map = new google.maps.Map(document.getElementById('map-canvas'),
    mapOptions);

  var drawingManager = new google.maps.drawing.DrawingManager({
    drawingMode: google.maps.drawing.OverlayType.MARKER,
    drawingControl: true,
    drawingControlOptions: {

    },
    markerOptions: {

    circleOptions: {

  });
  drawingManager.setMap(map);
  google.maps.event.addListener(drawingManager, 'circlecomplete', onCircleComplete);
 }

 function onCircleComplete(shape) {
      var map=shape.getMap();
      var circle;
       //create an array where we store the circles
       if(!map.get('circles')){
          map.set('circles',[]); 
        }
       shape.setOptions(
                      (!map.get('circles').length)
                        ?//first circle
                         {type:'source',
                          fillColor:'#ff0000'
                         }
                        ://other circles
                         {type:'destination'}
                    );
      //push the circles onto the array 
      map.get('circles').push(shape);

        circle = shape;
        radius = circle.getRadius();
        center = circle.getCenter();
        latitude = circle.getCenter().lat();
        longitude = circle.getCenter().lng();

         doStuff();
     //    alert(radius);

    }   
   google.maps.event.addDomListener(window, 'load', initialize);

function doStuff() {
  var where_stm = 'within_circle('+latitude+','+longitude+','+radius+')';

     $.ajax({

  <div id="container">
     <div id="sidebar-left">
        <p> Please select your source place by using drawing tools on the map. </p>

        Now you can select one or more destination on the map using the same drawing tools 
       </div>

       <button onClick="doStuff()">Run Code</button>

我的问题：当我在地图上画一个圆圈时，我在控制台上看到了这个错误： OPTIONS https://api.dandelion.eu/datagems/v2/SpazioDati/milano-grid/data [HTTP/1.1 405 Method Not Allowed 350ms]当我点击它时，我看到了：

我很感激您的所有想法，感谢

我通过Postman尝试了一个请求，使用GET和（仅！）您在代码段中提供的URL：200 / OK，没有任何缺陷。没有＆＃39;数据＆＃39;尝试它。它应该仅用于POST请求，而不是用于GET请求！

但是，因为你需要传递你的内心＆＃39;数据集，您应该考虑使用POST，这使您可以访问数据属性的使用，或者通过在URL中传递data-params来发出GET请求。由于我不知道API，我无法为您做出选择。

Ajax调用API返回错误HTTP / 1.1 405方法不允许
