google maps places auto complete api does not return plus code

问题描述 投票：0回答：1

我正在使用如下的地方自动完成 api:

 let place: google.maps.places.PlaceResult = autocomplete.getPlace();

        //verify result
        if (place.geometry === undefined || place.geometry === null) {
          return;
        }

console.log("formated address:", place.formatted_address)
console.log("plus cordinates:", place.plus_code)

我可以看到 formatted_addresss 正在打印，但 plus_code 未定义。根据文档 https://developers.google.com/maps/documentation/javascript/reference/places-service#PlaceResult

我应该看到它。

物体的反应是

address_components: (8) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}]
adr_address: "<span class=\"street-address\">12112 Anderson Mill Rd</span>, <span class=\"locality\">Austin</span>, <span class=\"region\">TX</span> <span class=\"postal-code\">78726</span>, <span class=\"country-name\">USA</span>"

根据文档，“plus_code”是optional：

plus_code可选
类型：PlacePlusCode 可选
为地点定义开放位置代码或“加号”。

这意味着它不能保证在那里。

您可以编写代码来处理不存在的情况。

概念证明

代码片段：

function initMap() {
  const map = new google.maps.Map(document.getElementById("map"), {
    center: {
      lat: 30.307984,
      lng: -97.753401
    },
    zoom: 13,
    mapTypeControl: false,
  });
  google.maps.event.addListener(map, "bounds_changed", function() {
    console.log("bounds=" + map.getBounds().toUrlValue(6));
  });
  google.maps.event.addListener(map, "zoom_changed", function() {
    console.log("zoom=" + map.getZoom());
  });
  google.maps.event.addListener(map, "center_changed", function() {
    console.log("center=" + map.getCenter().toUrlValue(6));
  })

    strictBounds: false,
    types: ["establishment"],
  };

  map.controls[google.maps.ControlPosition.TOP_LEFT].push(card);

  const autocomplete = new google.maps.places.Autocomplete(input, options);

  // Bind the map's bounds (viewport) property to the autocomplete object,
  // so that the autocomplete requests use the current map bounds for the
  // bounds option in the request.
  autocomplete.bindTo("bounds", map);

  const infowindow = new google.maps.InfoWindow();

      // pressed the Enter key, or the Place Details request failed.
      window.alert("No details available for input: '" + place.name + "'");
      return;
    }
    console.log("place:" + JSON.stringify(place))
    // If the place has a geometry, then present it on a map.
    if (place.geometry.viewport) {
