通过`resty.http` 调用 https 请求，一直报错

前提

电脑：

其他安装版本(使用nginx源码编译的方式集成 lua, 而非 openresty):

nginx version: nginx/1.23.4
lua version: Lua 5.4.5  Copyright (C) 1994-2023 Lua.org, PUC-Rio
luajit version: LuaJIT 2.1.0-beta3 -- Copyright (C) 2005-2022 Mike Pall. https://luajit.org/(使用的是openresty中的版本)
openssl verions: 3.1.0
pcre version: 1.x

nginx需要的模块(从openresty的 github 中下载):

lua-nginx-module(master分支)
ngx_devel_kit(master分支)
lua-resty-core(master分支, 需要 `make` 和 `make install` 到`/xxx/restry`目录)
lua-resty-lrucache(master分支, 需要 `make` 和  `make install` 到`/xxx/restry`目录)

lua-resty-http 模块:

1. 下载: https://github.com/ledgetech/lua-resty-http/tree/master, 
2， 通过 make 命令安装到 `xxx/restry` 目录下

配置 nginx，添加 resty 目录映射:

http {
   ...
  
  # 添加 lua_package_path
 lua_package_path '/xxx/restry/lib/lua/?.lua;;';
 lua_package_cpath '/xxx/restry/lib/lua/?.so;;';

  ...
 
}

开发

因为后台是使用的 https 的链接, 所以想通过nginx lua 直接调用，代码如下:

-- http.test.lua
local http = require('resty.http')
local client = http.new()
local res, err = client:request_uri(
  'https://xxx.com:9090/xxx',  -- 具体地址是 https 开头, 带 9090 端口
  {
     method = 'GET',
     keepalive_timeout = 30000
  }
)

nginx 配置:

location /test {
        default_type 'application/json'; #返回Json文本
        content_by_lua_file /xxx/http.test.lua; -- 对应上面 http.test.lua 文件地址
 }

现在报错信息如下:

查看 socket.lua 找到错误地方:

查看 http_connect.lua 找到错误地方:

http 请求正常，就是 https 报错，帮忙看一下，谢谢～

What makes you think this has anything to do with lua-resty-http? The error appears to be related to your installation / platform - you will get the same error calling https://github.com/openresty/lua-nginx-module#tcpsocksslhandshake from any Lua code.
