如何使用不带API密钥的谷歌地图 [英] How to use google maps without api key

问题描述

您好，我正在使用此代码在Google地图中使用获取方向。但是当我从其他机器运行它显示错误无效api键。

任何人都可以帮助我...提前致谢..
<您需要将API从V2更改为V3，因为Google地图版本3不需要API密钥

请查看此 out ..

将您的脚本编写为

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

编辑：此答案现在已过期。您现在需要有一个API密钥才能使用Google地图。请参阅下面的评论。

Hi i am using this code to use get-directions in google maps. but when i run this from other machines it is showing the error invalid api key. how to use this same map without an api key.

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

Can anyone help me...thanks in advance..

解决方案

you need to change your API from V2 to V3, Since Google Map Version 3 don't required API Key

Check this out..

write your script as

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

EDIT: This answer is now out-of-date. You are now required to have an API key to use google maps. See comments below.
