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
下载好后放入对应目录,这里的目录是:
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)
