Question

我制作了一个电报机器人，它根据URL的请求使用pyTelegramBotAPI包装器发送照片。所以我尝试放置一个虚拟照片URL并测试机器人是否可以发送图像，但是它失败并出现以下错误。

telebot.apihelper.ApiException: sendPhoto failed. Returned result: <Response [400]>

我不确定错误是什么，但如何正确使用Telegram Bot API从URL发送照片？这是我的代码

import telebot
import time
import urllib
from io import BytesIO
from PIL import Image

TOKEN = '<token here>'
url='http://scontent-b.cdninstagram.com/hphotos-xfa1/t51.2885-15/e15/10919672_584633251672188_179950734_n.jpg'

def listener(*messages):
    for m in messages:
        chatid = m.chat.id
        if m.content_type == 'text':
            text = m.text
            name = m.fromUser.first_name
            msgid = m.message_id
            if(text.startswith('/photo')):
                img = BytesIO(urllib.request.urlopen(url).read())
                tb.send_chat_action(chatid, 'upload_photo')
                tb.send_photo(chatid, img, reply_to_message_id=msgid)


tb = telebot.TeleBot(TOKEN)
tb.get_update()  # cache exist message
tb.set_update_listener(listener) #register listener
tb.polling()
while True:
    time.sleep(1)

我不确定我是否遗漏了一些东西。

试试这个：

import telebot
import time
import urllib

url = 'http://scontent-b.cdninstagram.com/hphotos-xfa1/t51.2885-15/e15/10919672_584633251672188_179950734_n.jpg'
f = open('out.jpg','wb')
f.write(urllib.request.urlopen(url).read())
f.close()

def listener(*messages):
    for m in messages:
        chat_id = m.chat.id
        if m.content_type == 'text':
            text = m.text
            msgid = m.message_id
            if text.startswith('/photo'):
                tb.send_chat_action(chat_id, 'upload_photo')
                img = open('out.jpg', 'rb')
                tb.send_photo(chat_id, img, reply_to_message_id=msgid)
                img.close()


tb = telebot.TeleBot(TOKEN)
tb.set_update_listener(listener) #register listener
tb.polling()

while True:
    time.sleep(0)

或（使用pyTelegramBotAPI 0.2.0）

import telebot
import time
import urllib

url='http://scontent-b.cdninstagram.com/hphotos-xfa1/t51.2885-15/e15/10919672_584633251672188_179950734_n.jpg'
f = open('out.jpg','wb')
f.write(urllib.request.urlopen(url).read())
f.close()

tb = telebot.TeleBot(TOKEN)

@tb.message_handler(commands=['photo'])
def send_photo(message):
    tb.send_chat_action(message.chat.id, 'upload_photo')
    img = open('out.jpg', 'rb')
    tb.send_photo(message.chat.id, img, reply_to_message_id=message.message_id)
    img.close()

tb.polling()

while True:
    time.sleep(0)

Answer 2

elif 'Hi' in text:
    reply(img=urllib2.urlopen('img url').read())
