如何在没有api密钥的情况下使用谷歌地图

Question

嗨,我正在使用此代码在谷歌地图中使用get-directions.但是当我从其他机器运行它时,它显示错误无效的api密钥.如何在没有api密钥的情况下使用同一个地图.

<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=false&amp;key=ABQIAAAAuPsJpk3MBtDpJ4G8cqBnjRRaGTYH6UMl8mADNa0YKuWNNa8VNxQCzVBXTx2DYyXGsTOxpWhvIG7Djw" type="text/javascript"></script>

table.directions th {

        GEvent.addListener(gdir, "error", handleErrors);

        setDirections("Bangalore", "Mysore", "en_US");

      gdir.load("from: " + fromAddress + " to: " + toAddress,

    function handleErrors(){

任何人都可以帮助我...提前谢谢..

Answer 1

注意:这个答案现在已经过时了.您现在需要有一个API密钥才能使用谷歌地图.阅读更多

您需要将API从V2更改为V3,因为Google Map版本3不需要API密钥

看看这个 ..

写你script的

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>

Answer 2

现在您必须拥有API密钥.您可以在谷歌开发者控制台中生成它.这是LINK的解释.

Answer 3

下面的代码不需要任何 api 即可在您的网站上嵌入地图

Answer 4

资源

2016年6 月, Google宣布他们将停止支持无密钥使用,这意味着任何不包含API密钥或客户端ID的请求.这将生效于2018年6月11日,和无钥匙进入将不会 再支持

Answer 5

例如，您仍然可以在 Google 地图共享按钮中使用免费的 w\xc4\xb1th iframe\n
