带有 Splash 的响应表中缺少时间键

如何解决带有 Splash 的响应表中缺少时间键

上周当我运行我的代码时，Splash 响应的表中有 timings。现在我再次运行代码它突然消失了。

local entries = splash:history()
if next(entries) ~= nil then
    local last_response = entries[#entries].response

    if (type(last_response) == "table") then
        for a,b in pairs(last_response) do
            print(a)
            if (type(b) == "table") then
                for c,d in pairs(b) do
                    print('\t',c)
                    print('\t\t',d)
                end
            else
                print('\t',b)
            end
        end
    end
end

返回：

什么可以解释 timings 的消失？

这是完整的 Splash 脚本：

function main(splash,args)
    local max_wait_time_in_seconds = 5
    local start_time = os.clock()

    local return_status
    local return_headers
    local return_timings
    local return_body_size

    assert(splash:go(args.url))

    while not splash:evaljs("document.readyState === 'complete'") do
        if (os.clock()-start_time > 10) then
            return nil
        end

        assert(splash:wait(0.05))
    end

    local entries = splash:history()
    if next(entries) ~= nil then
        local last_response = entries[#entries].response

        if (type(last_response) == "table") then
            for a,b in pairs(last_response) do
                print(a)
                if (type(b) == "table") then
                    for c,d in pairs(b) do
                        print('\t',c)
                        print('\t\t',d)
                    end
                else
                    print('\t',b)
                end
            end

            return_status = last_response.status
            return_headers = last_response.headers
            return_timings = last_response.timings
            return_body_size = last_response.bodySize
        end
    end

    return {
        html = splash:html(),headers = return_headers,timings = return_timings,http_status = return_status,body_size = return_body_size
    }
end

这是我的 SplashRequest：

yield SplashRequest(
    url = self.start_url,callback = self.parse_response,magic_response = True,endpoint = 'execute',args = {
        'lua_source': self.splash_lua_script
    }
)
