工欲善其事

Nginx 作为一个高性能web服务器其实也是可以扩展的比如结合Lua模块实现redis之类的认证等

server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        location /test {
        content_by_lua_block {
            local redis = require "resty.redis"
            local red = redis:new()

            red:set_timeout(1000) -- 1 sec

            local ok, err = red:connect("127.0.0.1", 6379)
            if not ok then
                ngx.say("failed to connect: ", err)
                return
            end

            -- 请注意这里 auth 的调用过程
            local count
            count, err = red:get_reused_times()
            if 0 == count then
            elseif err then
                ngx.say("failed to get reused times: ", err)
                return
            end

            ok, err = red:set("dog", "an animal")
            if not ok then
                ngx.say("failed to set dog: ", err)
                return
            end

            ngx.say("set result: ", ok)

            -- 连接池大小是100个，并且设置最大的空闲时间是 10 秒
            local ok, err = red:set_keepalive(10000, 100)
            if not ok then
                ngx.say("failed to set keepalive: ", err)
                return
            end
        }
    }

http {
    lua_package_path "/path/to/lua/scripts/?.lua;;"; # 设置 Lua 脚本路径

    server {
        listen 80;
        server_name localhost;

        location /signal {
            content_by_lua_block {
                local cjson = require "cjson"
                local method = ngx.req.get_method()

                if method == "POST" then
                    ngx.req.read_body()
                    local data = ngx.req.get_body_data()
                    local signal_data = cjson.decode(data)

                    -- 处理信令逻辑
                    ngx.say(cjson.encode({ status = "success", data = signal_data }))
                else
                    ngx.status = ngx.HTTP_BAD_REQUEST
                    ngx.say(cjson.encode({ status = "error", message = "Invalid request method" }))
                end
            }
        }

        location / {
            root /path/to/static/files; # 静态文件目录
            index index.html;
        }
