测试 composer 图像优化

啊，我明白了……看来是我的华为手机性能太弱，无法完成这个操作。不过我现在用 iPhone 试了一下，调整大小的功能运行得很顺畅。太棒了！谢谢

这张 9MB 的图片在这里可以正常显示，但在运行 2.8.0.beta3 版本的我们的网站上却无法使用（环境：Chrome 浏览器，Windows 桌面版 91）。当通过设备文件选择器选中该图片进行上传（而非拖拽）时，不会显示任何错误或用户提示信息，上传似乎被静默拒绝。

我们的“文件”设置均为默认配置（最大图片大小 4096 KB，启用编辑器媒体优化图片，使用 S3 存储，Cloudfront CDN 等）。

我在日志或浏览器控制台中找不到任何相关信息。较小的文件似乎可以正常工作并顺利调整大小。

接下来该怎么办？我需要查找哪些信息以进一步帮助诊断这个问题？

尝试启用详细日志：

# 通过 ssh 登录到服务器
cd /var/discourse
./launcher enter app
rails c
SiteSetting.composer_media_optimization_debug_mode = true

然后再次尝试上传图片，并在失败后打开浏览器日志。

另外，你能分享一下原始图片吗？

Here’s the original file: 9.01 MB file on MEGA

I’ve enabled SiteSetting.composer_media_optimization_debug_mode = true in the rails console but am not seeing anything in terms of extra output in the Chrome browser log as yet. Here’s the Chrome log for

您的站点存在两个问题。

您的站点位于 Cloudflare 全站点代理之后。您可以进入 DNS 设置，将橙色云朵图标变为灰色以禁用此功能。Discourse 在 Cloudflare 转换代理后已知会随机出现故障。
您的站点未配置 HTTPS。由于上述第 1 点，您之前并未发现此问题。如今，每个新的浏览器 API 都仅限于 HTTPS，且所有公共站点都应使用 HTTPS。您需要正确设置 HTTPS，然后再次进入 Rails 控制台并运行 SiteSetting.force_https = true。

fearlessfrog · 2021 年7 月 19 日 20:26

“问题”这个词太强烈了，更多是故意为之的奇怪行为 —— 如果你现在确信该功能与 Cloudflare 不兼容，我们就禁用这个新功能。我们并未使用 Brotli 或 Rocket Loader。

我们将 Cloudflare 用作 S3/Cloudfront 的泛域名解析方案，并通过页面规则实现 HTTPS 重定向，因此对我们而言这是有意为之，也能节省一些自建托管成本。S3 upload bucket, cdn url and bucket name in CNAME - #7 by fearlessfrog

Falco · 2021 年7 月 19 日 20:32

主要问题是，如果您的网站可通过 HTTPS 访问，则必须将 SiteSetting.force_https 设置为 true。您能试试吗？

我们使用该设置来生成 Discourse 论坛链接；如果没有它，例如邮件中的链接将默认为 HTTP：

fearlessfrog · 2021 年7 月 19 日 20:40

是的，这看起来有效了——谢谢！

我们之前一直没开启这个功能，因为 Cloudflare 端的“灵活（Flexible）”SSL 在安全方面本来就几乎等同于开放状态，而且无论什么情况，通过页面规则都会将传入请求重定向到 HTTPS，所以我不确定具体会有什么影响。由于 .mudspike.com 域名下还有其他网站需要这种 Cloudflare 配置，所以这个论坛的误配置状态已经持续一段时间了。

我们的 nginx 配置早已修复此问题。您上次重新构建是什么时候？能否尝试重新构建？

fearlessfrog · 2021 年7 月 19 日 20:42

我今天早上重新构建了——结果在这里：Commits · discourse/discourse · GitHub

编辑：实际上，我今天早上通过 Web UI 进行了升级，并获取了 Docker 管理器的升级包；不过我稍后会通过 SSH 重新构建并反馈结果。

fearlessfrog · 2021 年7 月 19 日 20:52

是的，最新的镜像已修复该问题——谢谢。

终于有一台真正的相机（Canon EOS Rebel SL3）来测试这个功能了，那就试试看吧：
