Nginx Different Proxy Depend On Method

https://stackoverflow.com/questions/8591600/nginx-proxy-pass-based-on-whether-request-method-is-post-put-or-delete

location ~* "(ngx.HTTP_POST|ngx.HTTP_DELETE|ngx.HTTP_PUT)" {
    proxy_pass http://127.0.0.1:8080;

    server {
  location / {
    # This proxy_pass is used for requests that don't
    # match the limit_except
    proxy_pass http://127.0.0.1:8080;

    limit_except PUT POST DELETE {
      # For requests that *aren't* a PUT, POST, or DELETE,
      # pass to :9080
      proxy_pass http://127.0.0.1:9080;
    }
  }
}

If is Evil… when used in location context

location / {
    error_page 418 = @other;
    recursive_error_pages on;

    if ($something) {
        return 418;
    }

    # some configuration
    ...
}

location @other {
    # some other configuration
    ...
}

对一段代码的疑惑

conn := db.freeConn[0]
copy(db.freeConn, db.freeConn[1:])
db.freeConn = db.freeConn[:numFree-1]

为什么不用 freeConn = freeConn[1:]

都两点了，赛赛还不睡觉，在床上疯。

爷爷强抱起来他去奶奶屋里，要哄他去睡觉。抱他去的路上，赛赛嘴里一直说，“抓走啦，抓走啦”。

今天妈妈哄睡的时候，听见赛赛在房间里面大哭了起来，我打开门进去看，赛赛自己爬下床，然后噔噔噔噔跑出去，跑去爷爷房间自己伸手把门开开找爷爷去了。

Golang Mod Replace

golang mod 里面的 replace 语法和应用简单学习一下。

语法

replace module-path [module-version] => replacement-path [replacement-version]

module-version: 可以用来指定特定的版本，如果不指定，则所有版本都替换

例子

例1 换成自己的 fork

require example.com/othermodule v1.2.3

replace example.com/othermodule => example.com/myfork/othermodule v1.2.3-fixed

例2 换成其他版本

require example.com/othermodule v1.2.2

replace example.com/othermodule => example.com/othermodule v1.2.3

例3 换成本地代码

require example.com/othermodule v1.2.3

replace example.com/othermodule => ../othermodule

require example.com/othermodule v1.2.5

replace example.com/othermodule v1.2.5 => ../othermodule
