Telegram Bot - 错误请求:指定了错误的文件标识符/HTTP URL [英] Telegram Bot - Bad Request: wrong file identifier/HTTP URL specified

问题描述

我在通过 sendDocument 方法将文件上传到电报时遇到了一个奇怪的问题.我正在用 python-telegram-bot 用 python 编写一个机器人.我尝试向用户发送一个 ZIP 文件，将 URL 作为 document.这是网址:http://telegram.someurl.tdl/32487352.zip>

I have a weird problem with uploading a file to telegram via the sendDocument method. I am writing a bot in python with python-telegram-bot. I try to send a ZIP file to a user, giving a URL as document. This is the URL: http://telegram.someurl.tdl/32487352.zip

bot.send_document(
    chat_id,
    document=document,
    filename=filename,
    timeout=60)

据我所知，我的文件遵循 Telegram 给出的规则:http://telegram.someurl.tdl/32487352.zip

As much as I know my file follows the rules given by Telegram: http://telegram.someurl.tdl/32487352.zip

• 向 Telegram 提供 HTTP URL
  • http://telegram.someurl.tdl/32487352.zip
  • 2.14 MB
  • 应用程序/zip
  • ZIP 文件

  这些是标题:

  Accept-Ranges →bytes
  Connection →keep-alive
  Content-Length →2247049
  Content-Type →application/zip
  Date →Sun, 29 Oct 2017 21:15:36 GMT
  ETag →"59f5e6e6-224989"
  Last-Modified →Sun, 29 Oct 2017 14:34:14 GMT
  Server →nginx/1.10.3 (Ubuntu)
  

  文件由 nginx (v1.10.3) 提供，配置简单.

  The file is served by nginx (v1.10.3), with this simple configuration.

  server {
      listen 80;
      server_name telegram.someurl.tdl;
  
      root /path/to/download_dir;
      location / {
          try_files $uri $uri/ =404;
      }
  }
  

  其中 /path/to/download_dir 当然替换为实际路径.

  Where /path/to/download_dir is replaced with the actual path of course.

  我得到的错误，正如标题所说，是这样的:

  The error I get, as said in the title, is this one:

  {
      "ok": false,
      "error_code": 400,
      "description": "Bad Request: wrong file identifier/HTTP URL specified"
  }
  

  同时发送另一个我在网上找到的 ZIP 文件:http://techslides.com/演示/样本/sample.zip

  Also sending another ZIP file which I found online works: http://techslides.com/demos/samples/sample.zip

  我已经搜索了解决方案，例如.这个 电报机器人奇怪的错误:错误的请求:指定了错误的文件标识符/HTTP URL 和这个 为什么我在电报机器人中收到错误的文件标识符/HTTP URL 指定错误? 没有帮助.

  I already searched for a solution and eg. this Telegram bot weird error : Bad Request: wrong file identifier/HTTP URL specified and this Why i get Wrong file identifier/HTTP URL specified error in telegram bot? do not help.

  希望你们能帮我解决这个问题.

  I hope you guys can help me with this.

  推荐答案

  我的一个朋友帮助了我，我们可以解决问题.根据 Telegram Bot API 文档，我所做的一切都是正确的，但看起来文档并不完整.

  A friend of mine helped me and we could fix the problem. Everything I did was correct according to the Telegram Bot API documentation, but as it looks the documentation is not complete.

  问题是我的文件名.文件必须以字母开头.它不能以数字开头.所以例如.test123.zip 和 t123.zip 有效，但 123.zip 或 1test.zip 无效.

  The problem was the name of my file. The file must start with a letter. It cannot start with a number. So eg. test123.zip and t123.zip work but 123.zip or 1test.zip do not.

  2020 年 7 月更新:

  似乎 Telegram 已更改其文件名政策.我只是尝试了以下名称，并且每个名称都有效.我的猜测是他们现在接受任何文件名，尽管并非每个客户端都以相同的方式保存文件:

  It seems that Telegram has changed it's filename policy. I just tried with the following names and every single one worked. My guess is they accept any filename now though not every client saves the file the same way:

  \-\-\-\-.zip   # in Telegram Desktop on Windows shown as "\-\-\-\-.zip" but saved as "_-_-_-_-.zip"
                 # in Telegram on Android shown and saved as "----.zip"
  hällo.zip
  1.zip
  test\nme.zip   # even with a filename with a literal new line character
                 # in Telegram Desktop on Windows shown as "testme.zip" but saved as "test_me.zip"
                 # in Telegram on Android shown and saved as "testme.zip"
  tttt.zip
  !test.zip
  test!.zip
  ttt.zip
  t.zip
  t1.zip
  1t.zip
  000.zip
  äääää.zip
  

  测试如下:

  for path in paths:
      print(path)
      chat.send_document('http://test.someurl.tdl/%s' % path, path)
