从发送的图像创建贴纸集

Question

我正在尝试使用用户发送给我的机器人的图像创建贴纸集。我有以下代码：

MY_USER_ID = "MyFakeUserId"
MY_TOKEN = "MyFakeToken"
import logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', level=logging.INFO)

from telegram.ext import Updater, MessageHandler, Filters, CommandHandler

updater = Updater(token=MY_TOKEN, use_context=True)
updater.start_polling()

dispatcher = updater.dispatcher

def create_sticker_set(update, context):

    update_dict = update.to_dict()

    sticker_file_id = update_dict["message"]["photo"][-1]["file_id"]

    print("sticker_file_id=", sticker_file_id)
    # sticker_file = context.bot.upload_sticker_file(MY_USER_ID, sticker_file_id)

    context.bot.create_new_sticker_set(MY_USER_ID, "lala_by_my_fake_bot", "lala", sticker_file_id, "????????????")

msghandler = MessageHandler(Filters.photo, create_sticker_set)
dispatcher.add_handler(msghandler)

我发送了一张大小正好为 512 像素 x 512 像素的 png 图片来聊天。而且这段代码不起作用。

我在日志中收到以下消息：

sticker_file_id= AgACAgQAAx0CUsT2sgADyF5SvWsoQ9ZTjw436M0nntrlkUtkAALjsTEb9W2ZUg-6JVL7B5D8wjq2GwAEAQADAgADeAADyYoDAAEYBA

    raise BadRequest(message)
telegram.error.BadRequest: Type of file mismatch

除了下载图片然后重新上传之外，我没有其他出路。像这样：

def create_sticker_set(update, context):

    update_dict = update.to_dict()

    sticker_file_id = update_dict["message"]["photo"][-1]["file_id"]

    print("sticker_file_id=", sticker_file_id)
    # sticker_file = context.bot.upload_sticker_file(MY_USER_ID, sticker_file_id)

    file = context.bot.get_file(update_dict["message"]["photo"][-1]["file_id"])
    filename = file.download()

    context.bot.create_new_sticker_set(MY_USER_ID, "lala_by_ibodi_bot", "lala", open(filename, "rb"), "????????????")

Answer 1

我找到了答案。将 png 文件作为照片而不是文件上传会将此文件转换为 jpg。 sticker_file_id 不是 context.bot.create_new_sticker_set 的正确参数，因为它是 jpg 文件的 file_id，它应该是 png 文件的 file_id。

此代码应该在我们将图片作为文件而不是照片上传的情况下工作。

MY_USER_ID = "MyFakeUserId"
MY_TOKEN = "MyFakeToken"
import logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', level=logging.INFO)

from telegram.ext import Updater, MessageHandler, Filters, CommandHandler

updater = Updater(token=MY_TOKEN, use_context=True)
updater.start_polling()

dispatcher = updater.dispatcher

def create_sticker_set(update, context):

    update_dict = update.to_dict()

    sticker_file_id = update_dict["message"]["document"]["file_id"]

    print("sticker_file_id=", sticker_file_id)
    # sticker_file = context.bot.upload_sticker_file(MY_USER_ID, sticker_file_id)

    context.bot.create_new_sticker_set(MY_USER_ID, "lala_by_my_fake_bot", "lala", sticker_file_id, "???")

msghandler = MessageHandler(Filters.document, create_sticker_set)
dispatcher.add_handler(msghandler)
