将Windows系统qBittorrent中的种子免校验转移到飞牛私有云的qBittorrent中

![](https://youjb.com/images/2024/09/25/image86e9893dedebb408.png)

qBittorrent 软件中所有的种子信息都有备份，保存在BT_backup文件夹中，该文件夹一般位于`C:\Users\Administrator\AppData\Local\qBittorrent\BT_backup`目录中。其中包括种子文件`*.torrent`及种子恢复文件`*.fastresume`。

> .fastresume文件是Bencode 编码，可以直接用文本编辑器打开，虽然有乱码，但是不影响查看文件夹相关信息，可以用来确定旧文件夹及查看脚本修改是否生效。当然不能直接修改，直接编辑器修改后编码就被破坏了，所以编辑器批量替换路径也是不行的。

###1、万事先备份，请先备份BT_backup文件夹

###2、然后，直接一个脚本解决：

```python
import os
import re

# 备份后的 BT_backup 文件夹路径，linux系统，所以根目录直接是/，如果是 win 系统，应该是类似 C:\格式开头，请根据自己的实际路径修改
torrentsDir = r'/Users/dt27/Downloads/BT_backup/'

# 新旧文件夹及其对应关系写在这里，
# 格式：b'旧文件夹路径': '新文件夹路径'
# 多个文件夹之间用英文逗号,分隔。
# Windows 文件夹这里写两个斜杠\\是因为单独一个斜杠\在代码中有特殊意义，所以要写两个表示转义，不明白的按我这么写就行了。
# 如果不确定旧文件夹，这一行可以直接写fastresumePaths = {} 这样会把所有种子的旧文件夹列出来。

fastresumePaths = {b'D:\\TV\\': b'/vol1/1000/TV', b'D:\\Movie\\': b'/vol1/1000/Movie', b'D:\\Music\\': b'/vol1/1000/Music'}

if not fastresumePaths:
    print('Finding paths...\n')
    detectedPaths = []

# Loop through torrents directory
for file in os.listdir(torrentsDir):
    if file.endswith('.fastresume'):
        with open(torrentsDir + file, 'rb') as fastresumeFile:
            filedata = fastresumeFile.read()
			
        #pattern = re.compile(br'save_path(\d+):')
        #query = pattern.search(filedata)
        query = re.search(br'save_path(\d+):', filedata)
		
        if query is None:
            print(f'Could not find path in {file}')
        else:
            pathLen = int(query.group(1))
            path = filedata[query.end():query.end() + pathLen]
            
            # check if user entered paths to change or not
            if fastresumePaths:
                print(fastresumePaths)
                if path in fastresumePaths:
                    newPath = fastresumePaths[path]
                    filedata = filedata.replace(
                        bytes(str(pathLen), 'utf-8') + b':' + path,
                        bytes(str(len(newPath)), 'utf-8') + b':' + newPath
                    )
                    print(f"Replaced {path} with {newPath}")
                
                    with open(torrentsDir + file, 'wb') as fastresumeFile:
                        fastresumeFile.write(filedata)
            else:
                if path not in detectedPaths:
                    detectedPaths.append(path)

if fastresumePaths is None or not fastresumePaths:    
    if not detectedPaths:
        print('No paths were found')
    else:
        print('The following paths were found\n')
        
        for path in detectedPaths:
            print(path)

print('\nCopy the following code into the "fastresumePaths" variable to replace paths.\n')
        
        maxPathLength = len(max(detectedPaths, key=len)) + 4
        
        print(f"#   {'Original Path'.ljust(maxPathLength)}  New Path")
        print(f"#  {'-'*(maxPathLength)}  {'-'*(maxPathLength)}\n")
        print('fastresumePaths = {')
        
        for path in detectedPaths:
            print(f"    {str(path).ljust(maxPathLength)}: {str(path).ljust(maxPathLength)},")

print('}\n')

本脚本在 MacOS 中测试无误，其他系统执行脚本时可能会出现报错信息，请根据报错信息自己排查。
一般就是路径格式或字符串格式的问题。
