如何在 aquarium/scrapy-splash 中加载 LUA 模块？

Question

我正在为 scrapy-splash 编写 LUA 脚本，想使用 socket.http 模块。该模块已安装，我已禁用沙箱并配置了包路径。但我无法让它工作。我的环境是 Linux.

上的水族馆

我已经使用 luarocks 安装了 luasocket 并添加了

--disable-lua-sandbox --lua-package-path "/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/?.lua"

到 docker-compose.yml 中的初始实例。

当我运行脚本时，出现以下错误：

"error": {"info": {"type": "LUA_INIT_ERROR", "message": "[string \"<python>\"]:1: module 'socket.http' not found:
    no field package.preload['socket.http']
    no file '/app/splash/lua_modules/socket/http.lua'
    no file '/app/splash/lua_modules/libs/socket/http.lua'
    no file '/usr/local/share/lua/5.1/socket/http.lua'
    no file '/usr/local/share/lua/5.1/socket/http/socket/http.lua'
    no file '/usr/local/share/lua/5.2/socket/http.lua'
    no file '/usr/local/share/lua/5.2/socket/http/init.lua'

    no file '/usr/share/lua/5.2/socket/http.lua'
    no file '/usr/share/lua/5.2/socket/http/init.lua'
    no file './socket/http.lua'
    no file '/usr/local/lib/lua/5.2/socket/http.so'

    no file '/usr/lib/x86_64-linux-gnu/lua/5.2/socket.so'
    no file '/usr/lib/lua/5.2/socket.so'
    no file '/usr/local/lib/lua/5.2/loadall.so'
    no file './socket.so'"}, "description": "Error happened while executing Lua script", "type": "ScriptError", "error": 400}, "qsize": 0, "status_code": 400}

即使文件 /usr/local/share/lua/5.1/socket/http.lua 存在于我的机器上。我也尝试 chmod 777 文件，但它仍然会抛出错误。

原来我不用socket.http.

我现在正在使用 splash:http_get and splash:http_post，它工作正常。
