我有一个带有 blogspot 的旅行博客。我有一个页面显示世界地图以及迄今为止所采取的路径。为此，我使用博客 API 来检索每个帖子的位置，如下所示:
<script src="https://www.googleapis.com/blogger/v3/blogs/3089072491354463482/posts?callback=handleResponse&key=AIzaSyAJO5J-pRCaGOIeRLIJfvAPwxpMLKvwebU">
我的问题是，似乎只检索了最后的帖子，而忽略了第一个帖子。在以下链接中，完整路径应包含阿根廷南部的所有地区，并链接到显示的当前路径。
http://el-gato-lindo.blogspot.com/p/map.html
生成 map 的完整代码如下:

关于html - Blogger API 未从博客中检索所有帖子，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16907328/
