Facebook调试器报告“检测到圆形重定向路径". (301)在某些网站上 [英] Facebook debugger reports "Circular redirect path detected" (301) on certain website

问题描述

为什么 Facebook调试器无法解析

Why isn't the Facebook debugger able to parse http://www.brandenburg-business-guide.de/ ? It reports 301 Circular redirect path detected. However, there is actually no redirection in place. Also apache's access.log reports no retrievals by facebook.

请参见推荐答案

该页面不包含任何 OpenGraph 元标记.查看文档.

The page does not contain any OpenGraph meta tags. Check out the documentation.

Facebook抓取工具希望页面包含og:url元标记，它将用作带有 rel ="canonical" 的规范URL OR 链接标记.由于两个文档都丢失了，因此Facebook无法确定什么是规范的url，因此会导致循环重定向路径错误.

Facebook scraper expects the page to contain og:url meta tag which will serve as the canonical url OR link tag with rel="canonical". Since the document is missing both, Facebook cannot decide what is the canonical url, hence the circular redirect path error.

作为参考，请尝试

For a reference, try Goodreads debugging information.
