使用Python解析Chrome浏览器书签的示例

Chrome 浏览器的书签如果可以导出，并转换为我们需要的格式时，我们就可以编写各种插件来配合书签的使用。

答案显然是可以的，接下来我们以 Python 为例写一个遍历打印书签的例子

书签地址

先来说下获取书签的方法

Chrome 浏览器的书签存放位置在各个平台的区别

Mac

~/Library/Application Support/Google/Chrome/Default/Bookmarks

Linux

~/.config/google-chrome/Default/Bookmarks

Windows

%LOCALAPPDATA%\"\\Google\\Chrome\\User Data\\Default\\Bookmarks\"

书签结构

书签内容为 JSON 格式，结构如下

{
  \"checksum\":\"b196f618a9166d56dc6c98cfe9a98d45\",
  \"roots\":{
    \"bookmark_bar\":{
      \"children\":[
        {
          \"date_added\":\"13246172853099058\",
          \"guid\":\"83431411-157f-45f8-a9a4-d9af26c71bce\",
          \"id\":\"1944\",
          \"name\":\"blog local 温欣爸比的博客\",
          \"type\":\"url\",
          \"url\":\"http://localhost:4000/\"
        },
        {
          \"children\":[
            {
              \"date_added\":\"13246172853099058\",
              \"guid\":\"83431411-157f-45f8-a9a4-d9af26c71bce\",
              \"id\":\"1944\",
              \"name\":\"blog local 温欣爸比的博客\",
              \"type\":\"url\",
              \"url\":\"http://localhost:4000/\"
            }
          ],
          \"date_added\":\"13246172844427649\",
          \"date_modified\":\"13246172865895702\",
          \"guid\":\"6aa4ecce-a220-4689-9239-7df10965748b\",
          \"id\":\"1943\",
          \"name\":\"Blog\",
          \"type\":\"folder\"
        }
      ],
      \"date_added\":\"13242060909278534\",
      \"date_modified\":\"13246172853099058\",
      \"guid\":\"00000000-0000-4000-a000-000000000002\",
      \"id\":\"1\",
      \"name\":\"书签栏\",
      \"type\":\"folder\"
    },
    \"other\":{
      \"children\":[

      ],
      \"date_added\":\"13242060909278616\",
      \"date_modified\":\"0\",
      \"guid\":\"00000000-0000-4000-a000-000000000003\",
      \"id\":\"2\",
      \"name\":\"其他书签\",
      \"type\":\"folder\"
    },
    \"synced\":{
      \"children\":[

      ],
      \"date_added\":\"13242060909278621\",
      \"date_modified\":\"0\",
      \"guid\":\"00000000-0000-4000-a000-000000000004\",
      \"id\":\"3\",
      \"name\":\"移动设备书签\",
      \"type\":\"folder\"
    }
  },
  \"sync_metadata\":\"\",
  \"version\":1
}

清晰了这个结构在写代码就很简单了，以书签栏为例，只需要将 data[\’roots\’][\’bookmark_bar\’][\’children\’] 进行循环遍历即可，代码详情可见 demo

  progress = 0
  step = 30
  while progress < total:
    time.sleep(1)
    b = progress
    e = b + step
    progress += step
    end = \'\\r\'
    if progress >= total:
      end = \'\\n\'
      progress = total
    print(get_progress(progress, total), end = end)

if __name__ == \"__main__\":
  print_progress(100)
