lua-web-utils和proxy设置示例

-- 首先安装lua-web-utils库
local lwu = require "lwu"
​
-- 获取服务器
local function get_proxy()
    local proxy_url = "duoipget_proxy"
    local resp, code, headers, err = lwu.fetch(proxy_url)
    if err then
        print("获取失败：", err)
        return nil
    end
    local json = lwu.json_decode(resp)
    if not json then
        print("无法解析服务器响应")
        return nil
    end
    return json.proxy
end
​
-- 下载的内容
local function download__com(proxy)
    local url = "com"
    local opts = {
        proxy = proxy,
        headers = {
            ["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36",
        },
    }
    local resp, code, headers, err = lwu.fetch(url, opts)
    if err then
        print("下载失败：", err)
        return nil
    end
    local content = lwu.json_decode(resp)
    if not content then
        print("无法解析下载内容")
        return nil
    end
    return content
end
​
-- 主函数
local function main()
    local proxy = get_proxy()
    if not proxy then
        return
    end
    local content = download_com(proxy)
    if content then
        print("下载成功：", content)
    end
end
​
-- 运行主函数
main()
