[英]How to send private message in Telegram Bot using Telegraf.js Node.js
[英]Telegram bot with telegraf.js : can't send random photo to chat using flickr api
我是電報機器人創建的新手,想制作一個簡單的機器人,允許用戶在命令中選擇歌手或演員照片,然后使用 flickr API 將其發送到聊天室:
const Telegraf = require('telegraf')
const { Router, Markup } = Telegraf
const axios = require('axios')
const api_key = '123'
const telegram = new Telegraf('123')
const inlineMessageRatingKeyboard = Markup.inlineKeyboard([
Markup.callbackButton('Singer', 'singer'),
Markup.callbackButton('Actor', 'actor')
]).extra()
const getSingerPhoto = () => {
axios.get(`https://www.flickr.com/services/rest/?method=flickr.photos.search&api_key=${api_key}&tags=gerard+way&format=json&nojsoncallback=1`)
.then(photosInfo => {
const photosArray = (photosInfo.data && photosInfo.data.photos && photosInfo.data.photos.photo) || null;
const photoObject = (photosArray && photosArray[photosArray.length * Math.random() | 0]) || null;
let { server, id, secret } = photoObject;
telegram.action('singer', (ctx) => {
ctx.replyWithPhoto({
url: `https://live.staticflickr.com/${server}/${id}_${secret}_q.jpg`
})
})
})
.catch(error => console.log(error));
}
telegram.on('message', (ctx) => ctx.telegram.sendMessage(
ctx.from.id,
'What kind of photo do you want?',
inlineMessageRatingKeyboard
)
)
telegram.command('singer', getSingerPhoto());
telegram.action('actor', (ctx) => {
ctx.replyWithPhoto({
source: './way.png'
})
})
telegram.startPolling()
Flickr API is okay - I get the photo array (photosArray) and then take a random photo object (photoObject) from it, then I put it to the necessary photo URL ( https://live.staticflickr.com/${server} /${id}_${secret}_q.jpg ),它也可以生成。
問題是它總是完全相同的照片,我必須總是重新啟動機器人來生成一張新照片 URL。 我在做什么錯,如何避免它並在每次用戶調用命令歌手時發送隨機照片? 任何幫助將不勝感激。
正如我在您的代碼中看到的那樣,您只執行一次 getSingerPhoto
telegram.command('singer', getSingerPhoto());
只需將其更改為
telegram.command('singer', getSingerPhoto);
編輯:
我不熟悉電報 api,但我也看到您在 axios 的響應中注冊操作,這就是照片被緩存的原因
telegram.action('singer', (ctx) => {
ctx.replyWithPhoto({
url: `https://live.staticflickr.com/${server}/${id}_${secret}_q.jpg`
})
})
因此,改為在getSingerPhoto(ctx)
中添加您將從命令/動作獲得的 ctx 參數,只需在內部調用它並刪除您內部的另一個動作
編輯2:完成的代碼:
const getSingerPhoto = (ctx) => {
axios.get(`https://www.flickr.com/services/rest/?method=flickr.photos.search&api_key=${api_key}&tags=gerard+way&format=json&nojsoncallback=1`)
.then(photosInfo => {
const photosArray = (photosInfo.data && photosInfo.data.photos && photosInfo.data.photos.photo) || null;
const photoObject = (photosArray && photosArray[photosArray.length * Math.random() | 0]) || null;
let { server, id, secret } = photoObject;
ctx.replyWithPhoto({
url: `https://live.staticflickr.com/${server}/${id}_${secret}_q.jpg`
})
})
.catch(error => console.log(error));
}
telegram.action('singer', getSingerPhoto);
