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)
