如何在 Telegram 机器人中使用 sendAudio (Python)

Question

我有一个 Telegram 机器人，它用文本和图像回复，但我在回复中发送 MP3 文件时遇到问题。有人可以帮忙吗？

这部分代码定义了回复：

        def reply(msg=None, img=None, aud=None):
        if msg:
            resp = urllib2.urlopen(BASE_URL + 'sendMessage', urllib.urlencode({
                'chat_id': str(chat_id),
                'text': msg.encode('utf-8'),
                'disable_web_page_preview': 'false',
                # 'reply_to_message_id': str(message_id),
                'reply_markup': json_keyboard,
            })).read()
        elif img:
            resp = multipart.post_multipart(BASE_URL + 'sendPhoto', [
                ('chat_id', str(chat_id)),
                ('reply_to_message_id', str(message_id)),
            ], [
                ('photo', 'image.jpg', img),
            ])
        elif aud:
            resp = multipart.post_multipart(BASE_URL + 'sendAudio', [
                ('chat_id', str(chat_id)),
                ('reply_to_message_id', str(message_id)),
            ], [
                ('audio', 'aud.mp3', aud),
            ])
        else:
            logging.error('no msg or img specified')
            resp = None

而这个定义了它应该return:

的消息类型

       elif 'Two' in text:
        img = Image.open('statimg/firstf.jpg')
        output = StringIO.StringIO()
        img.save(output, 'JPEG')
        reply(img=output.getvalue())
    elif 'Three' in text:
        aud = open('statimg/firsta.mp3')
        output = StringIO.StringIO()
        aud.save(output, 'MP3')
        reply(aud=output.getvalue())
    elif 'One' in text:
        # json_keyboard = json.dumps({keym: [bline3]})
        bline1 = [b1]
        bline2 = [b2]
        json_keyboard = json.dumps({keym: [bline1, bline2]})
        if func6.state == 0:
            reply('Hello text1')
            func6()
        elif func6.state == 1:
            func6()
            reply('Hello text2')

For "One" and "Two" in text ot works perfectly (returns text for "One" and image for "Two"), but for "Three" 它不是 return mp3 文件。

可能是什么问题？非常感谢！

Answer 1

我认为问题出在 output = StringIO.StringIO()

你应该使用 io.BytesIO()

这是我正在使用的工作代码：

def sendTelegramAudio(self, file_url, text):
    url = "https://api.telegram.org/botxxx:yyyy/sendAudio";
    remote_file = requests.get(file_url)
    file1 = io.BytesIO(remote_file.content)
    file1.name = 'audio.mp3'
    files = {'audio': file1}
    data = {'chat_id' : "@your_channel", 'caption':text}
    r= requests.post(url, files=files, data=data)
    print(r.status_code, r.reason, r.content)

这样简单地解决了问题：

        elif aud:
            resp = multipart.post_multipart(BASE_URL + 'sendAudio', [
                ('chat_id', str(chat_id)),
                #('caption', 'Music in the park'),
                ('reply_markup', json_keyboard),
            ], [
                ('audio', 'Play', aud),
            ])

reply(aud=urllib.urlopen('statimg/musone.mp3').read())
