python-3.x - 无法将音频上传到 Telegram 错误请求 : failed to get HTTP URL content

Question

我有 mp3 的工作 url，我正在尝试通过此 url 将音频发送到 Telegram。它有时会起作用，但大多数时候会出错

"A request to the Telegram API was unsuccessful. The server returned HTTP 400 
Bad Request. Response body:
[b'{"ok":false,"error_code":400,"description":"Bad Request: failed to get HTTP 
URL content"}']"

我不明白为什么，因为我检查了大小和类型，一切都很清楚，我在 Telegram API 的文档中找不到更多的限制。谁知道错误的原因是什么？

链接到 mp3 - http://data3.api.xn--41a.ws/vkp/cs9-5v4.userapi.com/p15/51bdb5ec5899ed.mp3

Answer 1

检查文件大小。

Provide Telegram with an HTTP URL for the file to be sent. Telegram will download and send the file. 5 MB max size for photos and 20 MB max for other types of content.

Post the file using multipart/form-data in the usual way that files are uploaded via the browser. 10 MB max size for photos, 50 MB for other files.
