nginx的lua模块提供了很多lua的函数API给用户使用,以便让lua更好的操作nginx
  • 24.1 Introduction
    这里说的Nginx api for lua,指的就是在nginx.conf文件中用*_by_lua 和*_by_lua_file指令 使用lua代码,为lua提供的专门的api。
  • 24.2 ngx.arg

    syntax: val = ngx.arg[index]

    context: set_by_lua*, body_filter_by_lua*

    通过用valua = ngx.arg[n],让nginx的变量作为参数传入lua给lua调用,使用方式如下列的代码
    location /foo {set$a32;set$b56;
     
            set_by_lua $sum'return tonumber(ngx.arg[1]) + tonumber(ngx.arg[2])'$a$b;
     
            echo $sum;}
    $sum 的值最后是88。
  • 24.3 ngx.var.VARIABLE

    syntax: ngx.var.VAR_NAME

    context: set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua*

    可以通过以下的代码进行读写nginx的变量
    value = ngx.var.some_nginx_variable_name
    ngx.var.some_nginx_variable_name=value
    location /foo {set$my_var'';# this line is required to create $my_var at config time
            content_by_lua '
                ngx.var.my_var = 123;
                ...
            ';}
    在lua代码里面就可以得到或者设置nginx.conf的变量,比较下跟上面的nginx.arg有什么区别~
  • 24.4 Core constants
    context: init_by_lua*, set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, *log_by_lua*, ngx.timer.*
    一些核心常量
      ngx.OK (0)
      ngx.ERROR (-1)
      ngx.AGAIN (-2)
      ngx.DONE (-4)
      ngx.DECLINED (-5)

  • 24.5 HTTP method constants
    context: init_by_lua*, set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, log_by_lua*, ngx.timer.*
      ngx.HTTP_GET
      ngx.HTTP_HEAD
      ngx.HTTP_PUT
      ngx.HTTP_POST
      ngx.HTTP_DELETE
      ngx.HTTP_OPTIONS   (added in the v0.5.0rc24 release)
      ngx.HTTP_MKCOL     (added in the v0.8.2 release)
      ngx.HTTP_COPY      (added in the v0.8.2 release)
      ngx.HTTP_MOVE      (added in the v0.8.2 release)
      ngx.HTTP_PROPFIND  (added in the v0.8.2 release)
      ngx.HTTP_PROPPATCH (added in the v0.8.2 release)
      ngx.HTTP_LOCK      (added in the v0.8.2 release)
      ngx.HTTP_UNLOCK    (added in the v0.8.2 release)
      ngx.HTTP_PATCH     (added in the v0.8.2 release)
      ngx.HTTP_TRACE     (added in the v0.8.2 release)
    一些http method的常量,一般用在ngx.location.capture 和ngx.location.capture_multi 这几个API的调用中~
  • 24.6 HTTP status constants
    context: init_by_lua*, set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, log_by_lua*, ngx.timer.*
      value = ngx.HTTP_OK (200)
      value = ngx.HTTP_CREATED (201)
      value = ngx.HTTP_SPECIAL_RESPONSE (300)
      value = ngx.HTTP_MOVED_PERMANENTLY (301)
      value = ngx.HTTP_MOVED_TEMPORARILY (302)
      value = ngx.HTTP_SEE_OTHER (303)
      value = ngx.HTTP_NOT_MODIFIED (304)
      value = ngx.HTTP_BAD_REQUEST (400)
      value = ngx.HTTP_UNAUTHORIZED (401)
      value = ngx.HTTP_FORBIDDEN (403)
      value = ngx.HTTP_NOT_FOUND (404)
      value = ngx.HTTP_NOT_ALLOWED (405)
      value = ngx.HTTP_GONE (410)
      value = ngx.HTTP_INTERNAL_SERVER_ERROR (500)
      value = ngx.HTTP_METHOD_NOT_IMPLEMENTED (501)
      value = ngx.HTTP_SERVICE_UNAVAILABLE (503)
      value = ngx.HTTP_GATEWAY_TIMEOUT (504)(first added in the v0.3.1rc38 release)
    http响应状态的常量
  • 24.7 Nginx log level constants
    context: set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, log_by_lua*, ngx.timer.*
      ngx.STDERR
      ngx.EMERG
      ngx.ALERT
      ngx.CRIT
      ngx.ERR
      ngx.WARN
      ngx.NOTICE
      ngx.INFO
      ngx.DEBUG
    nginx日志的一些级别常量,一般用在 ngx.log的api中
  • 24.8 print

    syntax: print(...)

    context: init_by_lua*, init_worker_by_lua*, set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, log_by_lua*, ngx.timer.*

    这个API是采用ngx.NOTICE的日志级别将参数的值写入error.log文件中,等同于ngx.log(ngx.NOTICE,...)
  • 24.9 ngx.ctx
    context: init_worker_by_lua*, set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, log_by_lua*, ngx.timer.*
    ngx.ctx.xxx xxx是任意的一个变量名,ngx.ctx可以看成一个临时字典,作用域是每一个请求,也就是说不同的request是不同的ngx.ctx
    如下面的例子
    location /test {
            rewrite_by_lua '
                ngx.say("foo = ", ngx.ctx.foo)
                ngx.ctx.foo = 76
            ';
            access_by_lua '
                ngx.ctx.foo = ngx.ctx.foo + 3
            ';
            content_by_lua '
                ngx.say(ngx.ctx.foo)
            ';}
    输出的结果是
        foo = nil
        79
    这个ngx.ctx.foo的实例是贯穿在一个请求中rewrite、access还有content三个周期。
    再看下面这个例子
    location /sub {
            content_by_lua '
                ngx.say("sub pre: ", ngx.ctx.blah)
                ngx.ctx.blah = 32
                ngx.say("sub post: ", ngx.ctx.blah)
            ';}
     
        location /main {
            content_by_lua '
                ngx.ctx.blah = 73
                ngx.say("main pre: ", ngx.ctx.blah)
                local res = ngx.location.capture("/sub")
                ngx.print(res.body)
                ngx.say("main post: ", ngx.ctx.blah)
            ';}
    结果是
        main pre: 73
        sub pre: nil
        sub post: 32
        main post: 73
    ngx.location.capture是请求另外一个链接,所以可以看到,sub和main中的ngx.ctx是不同的实例。
    另外在init_worker_by_lua的指令中,我们可以初始化ngx.ctx,通过字典的形式
    ngx.ctx = {foo = 32,bar = 54}
  • 24.10 ngx.location.capture

    syntax: res = ngx.location.capture(uri, options?)

    context: rewrite_by_lua*, access_by_lua*, content_by_lua*

    通过这个api,lua可以访问本server的其他location,只能是同一个server的。用法如下
     res = ngx.location.capture(uri)
    返回的是一个response对象,这个对象持有其他包括res.status、res.body以及res.header三个对象。
    -capture函数除了url还有其他参数可以选择,包括
    -method 设置访问的method类型
    -body 设置访问子请求的httpbody内容
    -args设置请求的参数
        ngx.location.capture('/foo?a=1',
            { args ={ b =3, c =':'}})
    等价于下面的调用,都是传递请求参数
        ngx.location.capture('/foo?a=1&b=3&c=%3a')
    -ctx 之前在ngx.ctx说的,在一个请求中独享一个ngx.ctx。但是在这里通过ctx,可以传入一个字典,然后通过子请求设置ngx.ctx的值,从而,我们在父请求中得到子请求ngx.ctx的值。

    location /sub {
            content_by_lua '
                ngx.ctx.foo = "bar";
            ';}location /lua {
            content_by_lua '
                local ctx = {}
                res = ngx.location.capture("/sub", { ctx = ctx })
     
                ngx.say(ctx.foo);
                ngx.say(ngx.ctx.foo);
            ';}

    结果如下,仅仅是设置ctx这个字典的值,而不是共享ngx.ctx

        bar
        nil
    -vars 这个参数用来在父请求中设置nginx的变量值并向子请求传递,这个方法比通过url参数传递更加有效果。
    location /other {
            content_by_lua '
                ngx.say("dog = ", ngx.var.dog)
                ngx.say("cat = ", ngx.var.cat)
            ';}
     
        location /lua {set$dog'';set$cat'';
            content_by_lua '
                res = ngx.location.capture("/other",
                    { vars = { dog = "hello", cat = 32 }});
     
                ngx.print(res.body)
            ';}
    结果如下
       dog = hello
        cat = 32
    -copy_all_vars 拷贝父请求的nginx的变量给子请求
    location /other {set$dog"$dog world";
            echo "$uri dog: $dog";}
     
        location /lua {set$dog'hello';
            content_by_lua '
                res = ngx.location.capture("/other",
                    { copy_all_vars = true });
     
                ngx.print(res.body)
                ngx.say(ngx.var.uri, ": ", ngx.var.dog)
            ';}
    结果如下
        /other dog: hello world
        /lua: hello
    -share_all_vars 同享父请求和子请求的nginx的变量。
    location /other {set$dog"$dog world";
            echo "$uri dog: $dog";}
     
        location /lua {set$dog'hello';
            content_by_lua '
                res = ngx.location.capture("/other",
                    { share_all_vars = true });
     
                ngx.print(res.body)
                ngx.say(ngx.var.uri, ": ", ngx.var.dog)
            ';}
    结果如下
        /other dog: hello world
        /lua: hello world
    这个比copy_all_vars优先。
    -always_forward_body 如果body属性没有设置,这个属性设置为true,那将发送父请求的httpbody给子请求。
  • 24.11 ngx.location.capture_multi

    syntax: res1, res2, ... = ngx.location.capture_multi({ {uri, options?}, {uri, options?}, ... })

    context: rewrite_by_lua*, access_by_lua*, content_by_lua*

    类似于上面的ngx.location.capture ,不过支持并行请求多个子请求
     res1, res2, res3 = ngx.location.capture_multi{{"/foo", { args ="a=3&b=4"}},
            {"/bar"},
            {"/baz", { method = ngx.HTTP_POST, body ="hello"}},
        }
     
        if res1.status == ngx.HTTP_OK then
            ...
        end
     
        if res2.body =="BLAH"then
            ...
        end
    -- construct the requests tablelocal reqs ={}table.insert(reqs, {"/mysql"})table.insert(reqs, {"/postgres"})table.insert(reqs, {"/redis"})table.insert(reqs, {"/memcached"})
     
        -- issue all the requests at once and wait until they all returnlocal resps ={ ngx.location.capture_multi(reqs)}
     
        -- loop over the responses tablefor i, resp inipairs(resps)do-- process the response table "resp"end

  • 24.12 ngx.status
    context: set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, log_by_lua*
    读取或者设置当前的请求响应状态,这个应该在发送内容给浏览器之前执行
        ngx.status = ngx.HTTP_CREATED
        status = ngx.status

  • 24.13 ngx.header.HEADER

    syntax: ngx.header.HEADER = VALUE

    syntax: value = ngx.header.HEADER

    context: rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, log_by_lua*

    获取或者设置http header的值
    -- equivalent to ngx.header["Content-Type"] = 'text/plain'
        ngx.header.content_type ='text/plain';
     
        ngx.header["X-My-Header"]='blah blah';
    多个值的可以像下面那样设置
        ngx.header['Set-Cookie']={'a=32; path=/', 'b=4; path=/'}
        Set-Cookie: a=32; path=/
        Set-Cookie: b=4; path=/
    特别是在header_filter_by_lua有效果,如
    location /test {set$footer'';
     
            proxy_passhttp://some-backend;
     
            header_filter_by_lua '
                if ngx.header["X-My-Header"] == "blah" then
                    ngx.var.footer = "some value"
                end
            ';
     
            echo_after_body $footer;}

  • 24.14 ngx.resp.get_headers

    syntax: headers = ngx.resp.get_headers(max_headers?, raw?)

    context: set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua, log_by_lua*

    context: set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*

    作用与rewrite相同,其中jump默认为false,false的时候
      ngx.req.set_uri("/foo", false)
    结果是
    rewrite ^ /foo break;
    如果jump为true,那就是

                    ngx.say("failed to get post args: ", err)
                    return
                end
                for key, val in pairs(args) do
                    if type(val) == "table" then
                        ngx.say(key, ": ", table.concat(val, ", "))
