博客网站地图JavaScript

Question

我使用的是一个javascript，它生成一个网站地图页面，所有帖子都按字母顺序和标签排序。它从这个链接中提取信息

https://blogname.blogspot.com/feeds/posts/default?max-results=9999

但不久前，博主为这些链接引入了分页，现在它们只显示150条帖子，所以网站地图只显示最后150条帖子的标题。

现在我必须使用多个链接来获得我所有的帖子，链接如下：

https://blogname.blogspot.com/feeds/posts/default?start-index=1&max-results=150
https://blogname.blogspot.com/feeds/posts/default?start-index=151&max-results=150
https://blogname.blogspot.com/feeds/posts/default?start-index=301&max-results=150
https://blogname.blogspot.com/feeds/posts/default?start-index=451&max-results=150
https://blogname.blogspot.com/feeds/posts/default?start-index=601&max-results=150

问题是，我不知道这个javascript是否可以使用多个链接，或者如何修改它，使其使用一个以上的链接来提取信息。

我的javascript知识很差，我尝试了一些有趣的修改，但都没有成功。我还尝试手动从几个链接中获取所有信息，并将它们合并到.txt文件中，然后将其上传到dropbox和pastebin上，但该脚本无法处理任何其他非我博客中的链接，不确定原因。

这是我说的脚本：

Answer 1

1. 在回调之前将JSON提要传递给另一个函数，使用spread运算符(…(或concat组合post-entries数组
2. 检查最后一个查询，然后进行回调：bloggersitemap((

---

var entries = [];
var successQuery = 0;
var totalQuery = 6; //your total feeds query <script> tag
function combineEntries(a) {
if ("entry" in a.feed) 
entries = [...entries,...a.feed.entry];
successQuery++;
if (successQuery == totalQuery)
{
bloggersitemap(
{feed:{entry:entries}}
);
entries = []; // avoid further manipulations to entries
}
}
