为什么Facebook调试器加薪：爬虫接受Deflate和GZIP内容编码

Question

得到此警告：图像不可用

Provided og:image, https://t44-post-cover.s3.eu-central-1.amazonaws.com/7ou5 could not be downloaded. This can happen due to several different reasons such as your server using unsupported content-encoding. The crawler accepts deflate and gzip content encodings.

如果我将get发送到https://t44-post-cover.s3.eu-central-1.amazonaws.com.com /7OU5和通过convect-编码：gzip和content-incoding：gzip在Postman中，我回到了GIF，那是什么问题？

内容小于8MB，为6.23 MB。

从Graph API中调用crawler：

{
  "error": {
    "message": "Invalid parameter",
    "type": "OAuthException",
    "code": 100,
    "error_subcode": 1611071,
    "is_transient": false,
    "error_user_title": "URL Follow Failed",
    "error_user_msg": "There was an error in fetching the object at URL 'https://tikex-dev.com/kubl/38fn/j1vd/2mi1', or one of the URLs specified via a redirect or the 'og:url' property including one of https://t44-post-cover.s3.eu-central-1.amazonaws.com/7ou5.",
    "fbtrace_id": "A4YG8eB4cFHG9acjUaDuCKk"
  }
}

我相信这是因为您没有将其链接到使用OG：Image的直接文件下载链接。
