It is recommended that you use the Lua module to reuse Lua code. Then, use require () in the user code to call Module code: Module (...) Local mytest = {} function mytest: GETID () Local STR = "123" Return strendreturn mytest There is such a line of code module (...) at the beginning, this is to name the module name with the file name Put the file in "/usr/local/openresty/lualib/lib" (or set lua_package_path) Call: Local test = require "Lib. myt

Use lua-nginx in openresty to create a socket instance This article mainly introduces how to use lua-nginx to create a socket instance in openresty. This article provides the code instance and running effect. For more information, see The Lua language is so powerful, at least I think so. The original Lua does not have the Socket function. You need to download the Lua socket component and require it. The l

In windows, openresty uses lua for interface forwarding and secondary encapsulation, and openrestylua Requirement: according to the customer's requirements, you can use lua in ngx to encapsulate the interface and re-forward it to the user or a third party. Scenario: If you have requirements for return values, the interface shields fields, or performs some business verification. 1. Download openresty in wind

When I described the Forminputnginxmodule module earlier, I understood how openresty obtained the data of the post submission.Then, if you need to process this data through LUA, you need to pass the data as a parameter into Lua, and Lua gets the data and returns the results to the Nginx to complete the process. First, there is a POST request:1 varJSON = {2Data"hello!"3 };4 $.post (5 'Save', 6 JSON,7 function (callback) {8 alert (callback);9

Openresty websocket use 1. The code is as follows: local server =require"resty.websocket.server" local wb, err = server:new{ timeout =5000, max_payload_len =65535 } ifnot wb then ngx.log(ngx.ERR,"failed to new websocket: ", err) return ngx.exit(444) end whiletruedo local data, typ, err = wb:recv_frame() if wb.fatal then ngx.log(ngx.ERR,"failed to receive frame: ", err) return ngx.exit(444) end if typ

Openresty provides a wealth of interfaces and variables to LUA, and developers can leverage the Lua language features and these interfaces for efficient development. Everything is hard at the beginning, but it is half the success of programming to write Hello World. 1. Installation Openresty 2. Configure Nginx Copy Code code as follows: server { Listen 80; server_name localhost;

This article mainly introduces the use of Lua-nginx in openresty to create a socket instance, this article directly gives code examples and running effects, need friends can refer to the following The LUA language is too powerful, at least that's how I feel. The original LUA does not have a socket function and requires the user to download the LUA socket component for a require. and the Lua-nginx module with the socket function, and is 100% non-block

0. Benefits of dynamic Upstream Openresty author, recently also open source (not open source when I write this article) they have used the Balancer-by-lua feature, progress issues. Can dynamically modify the upstream, using reverse proxy proxy_pass, to the back-end process or machine: dynamic load balancing control; smooth up and down service, upgrade service; High possible guarantee – Auto kick offline service downline; 1. First, the principle Ideas

Summary from: https://github.com/openresty/lua-nginx-module/#data-sharing-within-an-nginx-worker Data sharing for each nginx worker Define a LUA module and require it in Content_by_lua or Content_by_lua_block.It is recommended to share only read-only data. If you must share mutable data, be sure that the write operation is non-blocking.If you need data shared by all workers, you can choose:Ngx.shared.DICT or memcached , redis , MySQL orPostgre

The thing is this, I bought a VPS, each month flow is not a lot, I want to see how much traffic. But I do not want to go back to the mainframe, I do not want to use those monitoring software, the advantages of a fuss, so I want to get a script, and then Openresty read out, I have nothing to see eye. Get Traffic data The VPS operating system is CENTOS6, using shell commands or reading a file to get Can read the following two files, Venet0 is the net

For long polling scenarios, which are more common, the client synchronizes constantly in a synchronous request, and the server decides whether to respond to requests or hold requests to continue checking the data.Since PHP-FPM is single process single-threaded, a process can handle only one request at a time, so for this long polling scenario, a particularly large number of php-fpm processes are needed to handle high concurrency, which is particularly wasteful because most requests are hold on t

URL encoding is an encoding used by HTTP to transmit various parameters at a single URL clock. This encoding will encode special characters (such as ' = ', ' & ', ' + ') in the form of '% ', where is the hexadecimal representation of the character.
