# File actionpack/lib/action_dispatch/http/request.rb, line 321 def remote_ip=(remote_ip) @remote_ip = nil set_header "action_dispatch.remote_ip", remote_ip end
request_id() 链接
返回唯一的请求 ID,该 ID 基于防火墙、负载均衡器或 Web 服务器生成的 X-Request-Id 头,或者由 RequestId 中间件生成(该中间件设置 action_dispatch.request_id 环境变量)。
这个唯一的 ID 有助于在日志记录或调试时进行端到端请求跟踪。这依赖于 ActionDispatch::RequestId 中间件设置的 Rack 变量。
Source: 显示 | 在 GitHub 上
# File actionpack/lib/action_dispatch/http/request.rb, line 336 def request_id get_header ACTION_DISPATCH_REQUEST_ID end

send_early_hints(links) 链接
Early Hints 是一个 HTTP/2 状态码,表示有助于客户端开始准备处理最终响应的提示。
如果 env 包含 rack.early_hints,则服务器接受 HTTP2 推送链接头。
send_early_hints 方法接受如下的链接哈希:
send_early_hints("link" => "</style.css>; rel=preload; as=style,</script.js>; rel=preload")
如果您使用 javascript_include_tag 或 stylesheet_link_tag,则默认包含 Early Hints 头(如果支持)。
Source: 显示 | 在 GitHub 上
# File actionpack/lib/action_dispatch/http/request.rb, line 254 def send_early_hints(links) env["rack.early_hints"]&.call(links) end
