China launches Zhuque-3, achieving its first rocket recovery on land_我的网站

???ڇ?;

一 |     China launched the reusable rocket Zhuque-3 on Wednesday morning, achieving its first recovery of a rocket's first stage on land.    The Zhuque-3 Y2 rocket blasted off at 7:35 a.m. (Beijing Time) from the Dongfeng commercial space innovation pilot zone in northwest China.    The land-based recovery of the rocket's first stage was completed as planned, and the flight mission was a complete success.    This mission followed the successful sea-based net recovery of the Long March-10B's first stage on July 10.    It marked China's first successful land-based controlled recovery of a rocket's first stage using deployable landing legs, highlighting a major breakthrough in the country's reusable rocket technology.                    。

         应对思路很简单:给连接设置合理的超时阈值。客户端发完头部就超时、发body 也超时、整体发送还超时,三个时间窗口一收紧,攻击者就没了拖下去的空间。

二 |     http {    client_header_timeout 10s;   #读取请求头超时时间    client_body_timeout  10s;    #读取请求体超时时间    send_timeout         10s;    #发送响应超时时间    keepalive_timeout    30s;    #长连接保持时间         #限制单IP连接数,进一步压制慢连接    limit_conn_zone $binary_remote_addr zone=addr:10m;    server {    limit_conn addr 30;    }    }    这里的时间值不是越小越好。

三 | 如果你的接口有上传大文件的功能,client_body_timeout 可以放宽到 60 秒,甚至针对上传路径单独写一个 location。核心原则是:正常用户用不上那么长时间。    配置改完后用nginx -t 检查语法,reload 平滑生效。可以用 slowhttptest 工具自己压测一下,看改成 10 秒后连接还能不能被挂住。真实业务里我习惯把这几个值默认设为 10 秒,上传接口单独放开。
