IOError:[Errno 2]没有这样的文件或目录 [英] IOError: [Errno 2] No such file or directory

问题描述

我正在尝试在我的MySQL数据库的表的路径中添加所有种子文件的某些信息，但似乎我遇到了一些PATH问题. 如您所见，这里有完整的路径，它甚至可以检测到"charlie.torrent"，所以我不太了解问题所在.

I'm trying to add some informations of all the torrents file in a path to a Table of my MySQL database but it seems like i have some PATH problems. As you can see there is the full path and it even detect the "charlie.torrent" so i don't really understand what is the problem.

这是我的代码:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import mysql.connector
import bencode
import binascii
import hashlib
import os
import sys

conn = mysql.connector.connect(host="localhost",user="root",password="root", database="TORRENTS")
cursor = conn.cursor
path = "/home/florian/TorrentFiles"
dirs = os.listdir(path)
for file in dirs:
        try:
                with open(file, 'rb') as torrentfile:
                        torrent = bencode.bdecode(torrentfile.read())
                        user = ("torrent['info']['name']","torrent['info']['length'],'bytes'","(hashlib.sha1(bencode.bencode(torrent['info'])).hexdigest())")
                        cursor.execute("""INSERT INTO torrent_infos (Name, Size, Hash) VALUES(%s, %s, %s)""", user)
        except bencode.BTL.BTFailure:
                continue


conn.close()

我真的不理解我的脚本的以下输出:

And i really don't understand the following output of my script:

root@debian:/home/florian/Documents/mysite/polls# python bdd.py 
Traceback (most recent call last):
  File "bdd.py", line 17, in <module>
    with open(file, 'rb') as torrentfile:
IOError: [Errno 2] No such file or directory: 'charlie.torrent'

我已经看过其他相同的主题，没有任何结果.

推荐答案

您正在尝试打开位于path中的文件，但不包括该路径，该路径会尝试在您当前的工作路径中打开该文件Python脚本.例如，如果您的种子在/home/user/torrents中，则从/home/user/script.py运行脚本.当您执行open(file, 'rb')时，您正在执行/home/user/charlie.torrent，而不是/home/user/torrents/charlie.torrent.尝试用with open(os.path.join(path, file), 'rb')替换with open(file, 'rb').

You're trying to open a file located in path, but not including that path, which tries to open the file in the current working path of your Python script. For example, if you run the script from /home/user/script.py, while your torrents are in /home/user/torrents. When you do open(file, 'rb') you are doing /home/user/charlie.torrent as opposed to /home/user/torrents/charlie.torrent. Try replacing with open(file, 'rb') with with open(os.path.join(path, file), 'rb').
