使用Python解析Chrome瀏覽器書簽的示例

更新時(shí)間：2020年11月13日 15:22:27 作者：溫欣爸比

這篇文章主要介紹了使用Python解析Chrome瀏覽器書簽的示例，幫助大家更好的理解和使用python，感興趣的朋友可以了解下

Chrome 瀏覽器的書簽如果可以導(dǎo)出，并轉(zhuǎn)換為我們需要的格式時(shí)，我們就可以編寫各種插件來(lái)配合書簽的使用。

答案顯然是可以的，接下來(lái)我們以 Python 為例寫一個(gè)遍歷打印書簽的例子

書簽地址

先來(lái)說(shuō)下獲取書簽的方法

Chrome 瀏覽器的書簽存放位置在各個(gè)平臺(tái)的區(qū)別

Mac

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

Linux

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

Windows

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

書簽結(jié)構(gòu)

書簽內(nèi)容為 JSON 格式，結(jié)構(gòu)如下

{
  "checksum":"b196f618a9166d56dc6c98cfe9a98d45",
  "roots":{
    "bookmark_bar":{
      "children":[
        {
          "date_added":"13246172853099058",
          "guid":"83431411-157f-45f8-a9a4-d9af26c71bce",
          "id":"1944",
          "name":"blog local 溫欣爸比的博客",
          "type":"url",
          "url":"http://localhost:4000/"
        },
        {
          "children":[
            {
              "date_added":"13246172853099058",
              "guid":"83431411-157f-45f8-a9a4-d9af26c71bce",
              "id":"1944",
              "name":"blog local 溫欣爸比的博客",
              "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":"書簽欄",
      "type":"folder"
    },
    "other":{
      "children":[

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

      ],
      "date_added":"13242060909278621",
      "date_modified":"0",
      "guid":"00000000-0000-4000-a000-000000000004",
      "id":"3",
      "name":"移動(dòng)設(shè)備書簽",
      "type":"folder"
    }
  },
  "sync_metadata":"",
  "version":1
}

清晰了這個(gè)結(jié)構(gòu)在寫代碼就很簡(jiǎn)單了，以書簽欄為例，只需要將 data['roots']['bookmark_bar']['children'] 進(jìn)行循環(huán)遍歷即可，代碼詳情可見(jiàn) demo

    progress += step
    end = '\r'
    if progress >= total:
      end = '\n'
      progress = total
    print(get_progress(progress, total), end = end)

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