我是 Google Places Autocomplete API 和一般开发的新手，但我希望有人能帮助我指出正确的方向。我已经查看了 Google Places 文档和示例。在尝试复制 Google 的示例以获得更好的理解（http://code.google.com/apis/maps/documentation/javascript/examples/places-autocomplete.html）时，我在运行它时收到以下错误：

“Google Maps API 服务器拒绝了您的请求。请求中指定的“sensor”参数必须设置为“true”或“false”。”

令人抓狂的是我确实将“传感器”设置为“假”！请参阅下面的完整页面代码。任何建议将不胜感激。

试试这个脚本 

 <script>
  function initialize() {
 var mapOptions = {
  center: new google.maps.LatLng(-33.8688, 151.2195),
  zoom: 13,
  mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map_canvas'),
  mapOptions);

var input = document.getElementById('searchTextField');
var autocomplete = new google.maps.places.Autocomplete(input);

autocomplete.bindTo('bounds', map);

var infowindow = new google.maps.InfoWindow();
var marker = new google.maps.Marker({
  map: map
});

google.maps.event.addListener(autocomplete, 'place_changed', function() {
  infowindow.close();
  marker.setVisible(false);
  input.className = '';
  var place = autocomplete.getPlace();
  if (!place.geometry) {
    // Inform the user that the place was not found and return.
    input.className = 'notfound';
    return;
  }

  // If the place has a geometry, then present it on a map.
  if (place.geometry.viewport) {
    map.fitBounds(place.geometry.viewport);
  } else {
    map.setCenter(place.geometry.location);
    map.setZoom(17);  // Why 17? Because it looks good.
  }
  var image = new google.maps.MarkerImage(
      place.icon,
      new google.maps.Size(71, 71),
      new google.maps.Point(0, 0),
      new google.maps.Point(17, 34),
      new google.maps.Size(35, 35));
  marker.setIcon(image);
  marker.setPosition(place.geometry.location);

  var address = '';
  if (place.address_components) {
    address = [
      (place.address_components[0] && place.address_components[0].short_name || ''),
      (place.address_components[1] && place.address_components[1].short_name || ''),
      (place.address_components[2] && place.address_components[2].short_name || '')
    ].join(' ');
  }

  infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + address);
  infowindow.open(map, marker);
});

// Sets a listener on a radio button to change the filter type on Places
// Autocomplete.
function setupClickListener(id, types) {
  var radioButton = document.getElementById(id);
  google.maps.event.addDomListener(radioButton, 'click', function() {
    autocomplete.setTypes(types);
  });
}

setupClickListener('changetype-all', []);
setupClickListener('changetype-establishment', ['establishment']);
setupClickListener('changetype-geocode', ['geocode']);
  }

   google.maps.event.addDomListener(window, 'load', initialize);
    </script>
