javascript - 谷歌地图 API 没有 key ？

Question

如何在没有 key 的情况下使用 Google Maps v3 API？我在this example里见过但无法弄清楚具体是什么导致它不出错。

编辑:如果有人建议，StackOverflow 上有关此主题的其他答案已过时且不再适用。

Answer 1

A key is now required 。以前不需要这样做，并且在 2016 年 6 月 22 日之前使用 API 且无需 key 的网站已不再需要 key ，可以继续运行。

参见this blog post for additional information (相关文字如下):

As of June 22, 2016 we are making the following changes to the Google Maps APIs Standard Plan:

1. We no longer support keyless access (any request that doesn't include an API key). Future product updates are only available for requests made with an API key. API keys allow us to contact developers when required and help us identify misbehaving implementations.
2. We have implemented a simple 25,000 map loads per day free limit to new Google Maps JavaScript API, Static Maps API, and Street View Image API implementations. The confusing 90-consecutive-day grace period for these APIs is being retired on October 12, 2016. With this change, developers can predictably plan for growth while media sites and US nonprofits can request more quota at no charge via our dedicated support programs.
3. We have reduced the daily map load maximum limit you can purchase for Google Maps JavaScript API, Static Maps API, and Street View Image API from 1,000,000 to 100,000 requests per API.* We believe higher-volume developers are best served with a Premium Plan license, which includes technical support and a Service Level Agreement, and with this change we've also created consistency between Standard Plan quotas across our maps and web service APIs.
4. We now count Google Maps JavaScript API client-side requests towards the daily limit of the associated web service API.*

The new policies will apply immediately to all Maps API implementations created on or after June 22nd, 2016.

Existing applications have been grandfathered based on their current usage to ensure that they continue to function both now and in the future. We will also be proactively contacting all existing API key users who, based on usage growth patterns, may be impacted in the future. If you’re an existing user, please take the time to read our Policy Update for Standard Plan summary for details on how each of these changes might affect your implementation.
