Name

lua-resty-http - Lua http client driver for the ngx_lua based on the cosocket API

Status

This library is considered experimental and still under active development.

The API is still in flux and may change without notice.

Description

This Lua library is a http client driver for the ngx_lua nginx module:

http://wiki.nginx.org/HttpLuaModule

This Lua library takes advantage of ngx_lua's cosocket API, which ensures 100% nonblocking behavior.

Note that at least ngx_lua 0.5.0rc3 or ngx_openresty 1.0.11.3 is required.

Synopsis

lua_package_path "/path/to/lua-resty-http/lib/?.lua;;";

server {
    location /test {
        content_by_lua '
            local http = require "resty.http"
            local hc = http:new()

            local ok, code, headers, status, body  = hc:request {
                url = "http://www.qunar.com/",
                --- proxy = "http://127.0.0.1:8888",
                --- timeout = 3000,
                method = "POST", -- POST or GET
                -- add post content-type and cookie
                headers = { Cookie = "ABCDEFG", ["Content-Type"] = "application/x-www-form-urlencoded" },
                body = "uid=1234567890",
            }

            ngx.say(ok)
            ngx.say(code)
