模拟触摸精灵 httpGet 实现示例

function httpGet(url) -- 也能请求 ftp 资源 (此函数已内置，不需要再拷贝到自己脚本中，只是 lcurl 使用实例而已) 
    if (url:sub(1, 6) ~= "ftp://" and
        url:sub(1, 7) ~= "https://" and
        url:sub(1, 8) ~= "https://") then
        url = "https://"..url
    end
    local curl = require("curl.safe")
    local buffer_t = {}
    local write_f = function(s)
        buffer_t[#buffer_t + 1] = s
    end
    local noerr, err = pcall(function()
        curl.easy()
            :setopt(curl.OPT_URL, url)
            :setopt(curl.OPT_CONNECTTIMEOUT, 60)
            :setopt_writefunction(write_f)
        :perform()
    end)
    if (noerr) then
        return table.concat(buffer_t)
    else
        return nil, err
    end
