youtube-dl视频回应怎么走吗?

Question

我正在写一个电报机器人从YouTube下载视频，我使用YouTube -dl api，当我试图获得视频作为响应时，但视频只是下载到根目录，但脚本没有将其发送给用户，它给了我一个错误。

错误类型:

Test video sending

这是我的代码:

const telegramApi = require("node-telegram-bot-api");
const token = "myApi";
const fs = require("fs");
const youtubedl = require("youtube-dl-exec");
const bot = new telegramApi(token, { polling: true });

const start = () => {
bot.on("message", async (msg) => {
const text = msg.text;
const chatId = msg.chat.id;
const mode = "youtube";
if (text === "/start") {
await bot.sendSticker(
chatId,
"https://tlgrm.ru/_/stickers/b50/063/b5006369-8faa-44d7-9f02-1ca97d82cd49/1.webp"
);
await bot.sendMessage(chatId, "Пошла жара...");
}
if (mode === "youtube") {
console.log("Test video sending");
const video = await youtubedl(text, {
noWarnings: true,
preferFreeFormats: true,
}).then((output) => console.log(output));
bot.sendMessage(chatId, output);
}
});
};
start();

我做错了什么?

注:忽略mode变量，这是为了防止我想添加除youtube之外的其他服务。

乌利希期刊指南。如果我写机器人。sendMessage (chatId、输出)

如果我写:机器人。sendVideo (chatId、输出)

您是否尝试使用sendVideo方法?它支持mp4文件格式-在这里看到更多https://github.com/yagop/node-telegram-bot-api/blob/release/doc/api.md#TelegramBot+sendVideo

另外，output变量是未定义的，因为它在不同的作用域中。您应该将bot.sendX调用放在有console.log函数的回调中，因此:

}).then((output) => {
console.log(output)
bot.sendMessage(chatId, output); // or sendVideo
});
