lua 发送http请求

lua发送http请求，luajit默认没有http.lua库，需要下载并存放到luajit对应目录。

一、下载http.lua和http_headers.lua库

参考：https://www.zixuephp.net/article-448.html
bash

location = /testscript{
default_type text/plain;
content_by_lua_file html/luafile/test.lua;
}

bash

vim test.lua
local zhttp = require "resty.http"
1.运行后查看nginx错误日志，会提示没有http.lua文件：

2.下载http.lua和http_headers.lua库

下载页面：https://github.com/pintsized/lua-resty-http

直接下载：http_headers.lua-http.lua.rar

bash

[root@zixuephp resty]# pwd
/usr/local/LuaJIT/share/luajit-2.0.5/resty
git clone https://github.com/pintsized/lua-resty-http.git

重启nginx。

二、lua发送http请求代码

1.get请求

bash

local zhttp = require "resty.http"
local function http_post_client(url, timeout)
        local httpc = zhttp.new()

        timeout = timeout or 30000
        httpc:set_timeout(timeout)

        local res, err_ = httpc:request_uri(url, {
                method = "GET",
                headers = {
                    ["Content-Type"] = "application/x-www-form-urlencoded",
                }
        })
        httpc:set_keepalive(5000, 100)
        --httpc:close()
        return res, err_
end
    2.post请求

bash

local zhttp = require "resty.http"
local function http_post_client(url,body,timeout)
        local httpc = zhttp.new()

        timeout = timeout or 30000
        httpc:set_timeout(timeout)

        local res, err_ = httpc:request_uri(url, {
                method = "POST",
                body = body,
                headers = {
                    ["Content-Type"] = "application/x-www-form-urlencoded",
                }
        })
        httpc:set_keepalive(5000, 100)
         httpc:close()
        if not res then
            return nil, err_
         else if res.status == 200 then
             return res.body, err_
         else
             return nil, err_ end
         end

end

bash

--get
local resp, err = http_post_client("http://zixuephp.net/index.html?name=test",3000)
--post
local body = {"name" = "test"}
local resp, err = http_post_client("http://zixuephp.net/index.html?name=test",body,3000)
