Question

我想从频道下载所有照片。尝试使用https://github.com/danog/MadelineProto获取频道消息历史记录：

$MadelineProto->messages->getHistory([
    'peer' => "-100xxxxxx",
    'offset_id' => 0,
    'offset_date' => 0,
    'add_offset' => 0,
    'limit' => 25,
    'max_id' => 1000,
    'min_id' => 0,
    'hash' => 1,
]);

结果我得到了一系列带媒体的消息：

array(13) {
    ["_"] => string(7) "message"
    ["out"] => bool(false)
    ["mentioned"] => bool(false)
    ["media_unread"] => bool(false)
    ["silent"] => bool(false)
    ["post"] => bool(false)
    ["id"] => int(38)
    ["from_id"] => int(500100000)
    ["to_id"] => array(2) {
        ["_"] =>string(11) "peerChannel"
        ["channel_id"] =>int(1369700000)
    }
    ["date"] => int(1520150410)
    ["message"] => string(0) ""
    ["media"] => array(2) {
        ["_"] =>string(17) "messageMediaPhoto"
        ["photo"] =>array(6) {
            ["_"] => string(5) "photo"
            ["has_stickers"] => bool(false)
            ["id"] => int(5251753100000000000)
            ["access_hash"] => int(-6118957000000000000)
            ["date"] => int(1520150405)
            ["sizes"] => array(4) {
                [0] =>array(6) {
                    ["_"] => string(9) "photoSize"
                    ["type"] => string(1) "s"
                    ["location"] => array(5) {
                        ["_"] =>string(12) "fileLocation"
                        ["dc_id"] =>int(2)
                        ["volume_id"] =>int(235100000)
                        ["local_id"] =>int(250000)
                        ["secret"] =>int(5193339136300000000)
                    }
                    ["w"] => int(90)
                    ["h"] => int(67)
                    ["size"] => int(1078)
                }
                ....

现在我想下载这个文件并且不知道怎么做。方法https://core.telegram.org/bots/api#getfile请求 file_id ，但我没有。

消息历史记录只给我这张照片参数：

ID
access_hash
dc_id
volume_id
local_id
秘密

如何从可用数据中获取file_id或生成它？

或者如何通过其他方式从频道历史记录中下载照片？

Answer 1

MadelineProto具有未记录的功能，如 download_to_file 或 download_to_dir 。

async

从没有file_id的Telegram频道历史记录下载照片
