同步文件夹

说明：网盘要么有同步文件夹数量限制，要么不过滤就一股脑全上传整个文件夹，于是花了一两个小时写了个脚本优化一下，缺点是额外占用存储空间，原理就是py先检测差异，然后同步到本地文件夹，再通过网盘同步本地的同步文件夹

下面是我自用的JSON，功能就是从文档里挑选出list这几个子文件夹，然后同步文件到我指定的target目录，同步完再到网盘里添加D:\\Yunchu为同步目录就可以了，如果要同步source和target的文件需要重新运行脚本

作用大概就是可以无限添加同步文件夹，且可以只保留需要的子文件夹

json
```
{
"Yunchu": "1.0",
"enumeration": [
   {
         "source": {
            "mode": "contains",
            "path": "C:\\Users\\25678\\Documents",
            "list": [
               "GitHub",
               "My Games",
               "图片"
            ]
         },
         "target": "D:\\Yunchu\\Documents"
   }
]
}
```

code
```
import filecmp
import os
import shutil
import json

def GetFileDiff(source_dir, target_dir, inherit=None):
if inherit == None:
   this = []
else:
   this = inherit

dir_cmp = filecmp.dircmp(source_dir, target_dir)

for path_name in dir_cmp.left_only:
   filepath = os.path.join(source_dir, path_name)
   filetype = "dir" if os.path.isdir(filepath) else "file"

   if filetype == "dir":# 取出目录下的子文件
         for root, dir, files in os.walk(filepath):
            for file in files:# 全文件夹进行复刻
               source = os.path.join(root, file)
               target = target_dir + source
               target = os.path.abspath(target)
               bag = {
                     "source": source,
                     "target": target
               }
               this.append(bag)
   else:# 非子目录新增文件
         source = os.path.join(source_dir, filepath)
         target = target_dir + source
         target = os.path.abspath(target)
         bag = {
            "source": source,
            "target": target
         }
         this.append(bag)

for path_name in dir_cmp.diff_files:# 目标或源目录文件发生变化时更新目标目录文件
   this.append(os.path.join(source_dir, path_name))# 文件压缩后会与源文件不同

for path_name in dir_cmp.right_only:
   # 将目标文件夹中新增的文件移动到变更文件夹中或删除
   os.remove(os.path.abspath(os.path.join(target_dir, path_name)))

for common_dir in dir_cmp.common_dirs:
   new_source = os.path.join(source_dir, common_dir)
   new_target = os.path.join(target_dir, common_dir)
   GetFileDiff(new_source, new_target, this)

return this

config = None
with open("config.json", encoding="utf-8") as file:
config = json.loads(file.read())

print(config)

def transfer(source, target):
os.makedirs(source, exist_ok=True)
os.makedirs(target, exist_ok=True)

diffs = GetFileDiff(source,target)

for diff in diffs:
   os.makedirs(os.path.dirname(diff['target']), exist_ok=True)
   shutil.copy(diff['source'], diff['target'])

for i, obj in enumerate(config['enumeration']):
obj_type = type(obj['source'])
if obj_type == dict:
   path = obj['source']['path']
   items = obj['source']['list']

   for item in items:
         source = os.path.join(path, item)
         target = os.path.join(obj['target'], item)

         transfer(source, target)
else:
   source = obj['source']
   target = obj['target']
   transfer(source, target)
print(i, obj)

```

这是一个思路，目前市面上有很多的同步空间替代品，而且还是开源的。我这里用"FreeFileSync"
