在做我的项目时，代码中出现了一个问题。我正在开展我的学校项目，发现了一个问题，即当其他较大的消息正在悄悄发送时，电报 API 不允许发送一部分消息。
我的错误完全是这样的-
2024-03-17 00:01:25,850（init.py:1147 MainThread）错误 - TeleBot：“线程轮询异常：对 Telegram API 的请求失败。错误代码：400。描述：错误请求：消息标题太长” 2024-03-17 00:01:25,852（init.py:1149 MainThread）错误 - TeleBot：“异常回溯： 回溯（最近一次调用最后一次）： 文件“C:\Users\Василий\AppData\Roaming\Python\Python311\site-packages elebot_init_.py”，第 1141 行，位于 _threaded_polling self.worker_pool.raise_exceptions() 文件“C:\Users\Василий\AppData\Roaming\Python\Python311\site-packages elebot\util.py”，第 149 行，在 raise_exceptions 中 引发 self.exception_info 文件“C:\Users\Василий\AppData\Roaming\Python\Python311\site-packages elebot\util.py”，第 92 行，运行中 任务（*args，**kwargs） 文件“c:\project\project_code\main.py”，第 178 行，位于 list_of_legs_exercises 中 bot.send_photo（message.chat.id，exercise_image，exercise_description） 文件“C:\Users\Василий\AppData\Roaming\Python\Python311\site-packages elebot_init.py”，第 2125 行，在 send_photo 中 apihelper.send_photo( 文件“C:\Users\Василий\AppData\Roaming\Python\Python311\site-packages elebot pihelper.py”，第 496 行，在 send_photo 中 return _make_request(token, method_url, params=payload, files=files, method='post') ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 文件“C:\Users\Василий\AppData\Roaming\Python\Python311\site-packages elebot pihelper.py”，第 164 行，在 _make_request 中 json_result = _check_result(方法名称, 结果) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 文件“C:\Users\Василий\AppData\Roaming\Python\Python311\site-packages elebot pihelper.py”，第 191 行，位于 _check_result 中 引发 ApiTelegramException（方法名称，结果，结果 json） telebot.apihelper.ApiTelegramException：对 Telegram API 的请求失败。错误代码：400。描述：错误请求：消息标题太长

我尝试减少文本量，尽管它无论如何都没有违反限制，但它减少了数据库 - 它没有帮助
我尝试询问GPT，这就是他的答案，也许它可以帮助你： 您遇到的错误“错误请求：消息标题太长”表示您尝试通过 Telegram 发送的照片附带的标题太长。 Telegram 对媒体文件附带的标题的长度有限制。
要解决此问题，您需要确保附加到照片的标题在 Telegram 允许的限制范围内。如果标题超出此限制，您可以调整代码以截断或修改标题。
以下是修改代码来处理此问题的方法：
```python
def list_of_legs_exercises(message):
if message.text == 'Нет никакого инвентаря':
exercise_images = exercise_manager.get_legs_exercise_image_by_availability(('1'))
exercise_descriptions = exercise_manager.get_legs_exercise_description_by_availability(('1'))
x = 0
for i in exercise_images:
exercise_image = i[0]
exercise_image = Image.open(io.BytesIO(exercise_image))
exercise_description = exercise_descriptions[x]
x+=1
# Truncate caption if it's too long
caption = exercise_description[:1024] # Limiting to 1024 characters
bot.send_photo(message.chat.id, exercise_image, caption)
elif message.text == 'Есть гантели или гири':
exercise_images = exercise_manager.get_legs_exercise_image_by_availability(('2'))
exercise_descriptions = exercise_manager.get_legs_exercise_description_by_availability(('2'))
y = 0
for i in exercise_images:
exercise_image = i[0]
exercise_image = Image.open(io.BytesIO(exercise_image))
exercise_description = exercise_descriptions[y]
y+=1
# Truncate caption if it's too long
caption = exercise_description[:1024] # Limiting to 1024 characters
bot.send_photo(message.chat.id, exercise_image, caption)
if message.text == 'Хожу в тренажерный зал':
exercise_images = exercise_manager.get_legs_exercise_image_by_availability(('3'))
exercise_descriptions = exercise_manager.get_legs_exercise_description_by_availability(('3'))
z = 0
for i in exercise_images:
exercise_image = i[0]
exercise_image = Image.open(io.BytesIO(exercise_image))
exercise_description = exercise_descriptions[z]
z+=1
# Truncate caption if it's too long
caption = exercise_description[:1024] # Limiting to 1024 characters
bot.send_photo(message.chat.id, exercise_image, caption)
```
在此修改中，我将标题限制为 1024 个字符。您可以根据 Telegram 当前的限制和您的具体要求调整此限制。
