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)
