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_ratio = progress / total
  progress_len = 20
  progress_num = int(progress_ratio * 20)
  pro_text = '[{:-<20s}] {:.2f}% {} / {}'.format(
    '=' * progress_num, progress_ratio * 100, progress, total)
  return pro_text

def print_progress(total):

  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)
