【问题描述】：
我是一名初级 ruby on rails 开发人员。我开发了一个使用 Google maps javascript API 的网络应用程序，并在表单输入上使用了自动完成功能。
自动完成功能在 localhost 上工作正常，但在部署到 heroku 后不再工作。
下面是我的 html.erb。为了您的完美信息，表格位于页脚中。此表单部分隐藏，唯一可见的部分对应于用于上传视频文件的按钮。单击此按钮并选择视频文件后，我将显示一个包含表单其余部分的模式。这就是显示“text_field_tag”（id =“user_input_autocomplete_address”）以及自动完成应该工作的地方。

</html>最后，允许输入自动完成的 javascript 代码（将“user_input_autocomplete_address”作为 id）位于 assets/javascript/autocomplete.js 中，如下所示：
function initializeAutocomplete(id) {
var element = document.getElementById(id);
console.log('coucou');
if (element) {
var autocomplete = new google.maps.places.Autocomplete(element, { types: ['geocode', 'establishment'] });
google.maps.event.addListener(autocomplete, 'place_changed', onPlaceChanged);
}
}
function onPlaceChanged() {
var place = this.getPlace();
console.log(place); // Uncomment this line to view the full object returned by Google API.
for (var i in place.address_components) {
var component = place.address_components[i];
// console.log(component.types);
for (var j in component.types) { // Some types are ["country", "political"]
var type_element = document.getElementById(component.types[j]); // Returns the div with their differents ids or null if the id doesnt exist
// console.log(document.getElementById(component.types[j]));
if (type_element) {
type_element.value = component.long_name;
}
}
}
var formatted_address = document.getElementById('formatted_address');
// console.log(international_phone_number);
if (formatted_address) {
formatted_address.value = place.formatted_address;
}
for (var i in place.types) {
// console.log(place.types);
// console.log(i);
// console.log(place.types[i]);
var type_content = document.getElementById('category_' + i); // Returns the div with their differents ids or null if the id doesnt exist
// console.log(document.getElementById(component.types[j]));
if (type_content) {
console.log(place.types[i]);
type_content.value = place.types[i];
}
}
var international_phone_number = document.getElementById('phone_number');
// console.log(international_phone_number);
if (international_phone_number) {
international_phone_number.value = place.international_phone_number;
}
var name = document.getElementById('name');
if (name) {
name.value = place.name;
}
var gplace_id = document.getElementById('gplace_id');
if (gplace_id) {
gplace_id.value = place.place_id;
}
var website = document.getElementById('website');
if (website) {
website.value = place.website;
}
for (var i in place.opening_hours.weekday_text) {
var hours_open_in_db = place.opening_hours.weekday_text[i];
var hours_open_in_form = document.getElementById('hours_open_day_' + i);
if (hours_open_in_form) {
hours_open_in_form.value = hours_open_in_db;
}
}
}
google.maps.event.addDomListener(window, 'load', function() {
initializeAutocomplete('user_input_autocomplete_address');
});为了在 heroku 上部署所有这些，我已经做了以下操作：
- "heroku run db:migrate" 在终端中（因为我有一些待处理 迁移）；
- "figaro heroku:set -e production" 在终端中，以便将我所有的 API 密钥推送到 heroku（我还检查了这些密钥确实在 heroku 的配置变量中）。
- 在 Google 的开发人员控制台、我的项目和 Google 地图 JavaScript API 中，我确保我的浏览器密钥对我的本地主机和我的域名都允许。为了非常精确，我对我的本地主机和我的域名使用相同的密钥。到目前为止，在 Google 的控制台中，我唯一没有做到的就是证明我拥有我的域名。
- 我检查了我尚未达到任何 API 配额。
- 在我的 autocomplete.js 文件中，我使用了一些 console.log，以便在浏览器的检查器中找出代码的哪些部分正在工作。似乎除了'OnPlaceChange'回调中的console.logs之外一切正常，因为没有显示Gmap的自动完成建议......；
- 我知道看不到自动完成建议不是与 .pac-container css 元素相关联的 z-index 问题，因为我已经必须解决这个问题，而且由于我的键盘箭头无法达到 Gmaps 建议。
- 我阅读了这篇关于 geocomplete (geocomplete for rails 4 not working in Heroku) 的帖子，并尝试预编译我的资产。这并没有带来任何改变。
- 在我的浏览器检查器中（在“网络”部分），当我在表单输入中写一些东西时，键盘上按下的每个新字母都会触发一个新请求。这些请求名称是“AutocompletionService.GetPredictions ...”。在“标头”部分，我可以看到它们是对 googleapis 的 https 请求，带有 get 方法和 200 状态码。在“响应”部分，我可以看到我的 API 密钥似乎有错误，因为消息是：
/**/_xdc_._ty4oqn && _xdc_._ty4oqn( [3,null,null,"This API project is not authorized to use this API. Please ensure that this API is activated in the APIs Console: https://console.developers.google.com/apis/library?project=_ Please ensure this API is activated in the Google Developers Console: https://console.developers.google.com/apis/api/places_backend?project=_ For more information on authentication and Google Maps Javascript API services please see: https://developers.google.com/maps/documentation/javascript/get-api-key"] )最后一点是问题的根源（在这种情况下，我想我需要托管服务的帮助）还是你们看到另一个错误？
