Google Maps API V3中的API密钥是什么？ [英] What's the API Key for in Google Maps API V3?

问题描述

在旧版本的API中，我必须使用类似这样的东西将JavaScript插入到页面中，以实现基本功能：

和您的浏览器的控制台会告诉您原因：

Google Maps API错误：MissingKeyMapError https://developers.google.com/maps/documentation/javascript/error-messages#missing-key- map-error

In the older version of the API, I'd have to insert the javascript into the page using something like this for just basic functionality to work:

http://maps.google.com/maps?file=api&v=2&key=GoogleMapsAPIKey

Where I had to configure the API key for each individual site. Looking at the documentation, it says to get a basic map working I just need this:

http://maps.google.com/maps/api/js?sensor=true/false

Where does the API key fit in? Do I need to worry about it if I just plan on using a basic map and marker and none of the more advanced functions?

I'm also testing on localhost, but the FAQ says I still need to register a key for it, which I haven't done and it still works.

解决方案

As of June 22, 2016 Google Maps V3 no longer supports keyless access so you need to get a key for every (referrer-)domain which has never had a Google Map on it before.

Get your key here: https://developers.google.com/maps/documentation/javascript/get-api-key

and append it to the URL of the script like so:

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY" type="text/javascript"></script>

If you do not provide an API key you will see this warning instead of your rendered map:

and your browser's console will tell you the reason:

Google Maps API error: MissingKeyMapError https://developers.google.com/maps/documentation/javascript/error-messages#missing-key-map-error
