制作Chrome书签同步插件

作为Chrome的重度使用者，解决了访问Google的问题之后，书签又经常不能同步。

利用Chrome的Api接口获取所有书签，然后上传到自己的服务器数据库保存。本来想使用七牛云的接口储存，但是七牛云只能上传文件保存。所以自己实现了一个简单的Flask框架Python后台来保存。

• 上传书签到服务器
• 从服务器拉取书签恢复(待实现)

syncing

179个书签上传成功

主要逻辑:

chrome.bookmarks.getTree()接口返回的书签数据是数组和树结合的，使用递归比较方便提取。

document.addEventListener('DOMContentLoaded', function() {
  getBookmarks();
});

var bookmarks;
function getBookmarks(){
    bookmarks = []
    chrome.bookmarks.getTree(function(result){
        
        for(var i=0;i

后台实现:

@app.route('/uploadBookmark', methods=['POST'])
def uploadBookMark():
    key = request.form.get('key')
    data = request.form.get('data')
    return dbBookmark.saveBookMark(key, data)

import json
import os
import sqlite3

PROJECT_ROOT = os.path.dirname(os.path.realpath(__file__))
DATABASE = os.path.join(PROJECT_ROOT, 'bookmark.chromeExtension')


def initDB():
    conn = None
    try:
        conn = sqlite3.connect(DATABASE)
        cursor = conn.cursor()
        cursor.execute(
            'CREATE TABLE bookmark (id INT PRIMARY KEY , parentId INT, indexId INT,url VARCHAR (20),title VARCHAR(20))')
        cursor.close()
        conn.commit()
    except BaseException as e:
        print e
    finally:
        if conn:
            conn.close()


def saveBookMark(key, data):
    bookMarks = json.loads(data)
    data = bookMarks.get('data')

    conn = None
    count = 0
    error = 'null'
    try:
        conn = sqlite3.connect(DATABASE)
        cursor = conn.cursor()
        sql = "DELETE FROM bookmark"
        cursor.execute(sql)
        for bookMark in data:
            id = bookMark.get('id')
            pId = bookMark.get('parentId')
            iId = bookMark.get('index')
            url = bookMark.get('url').encode('utf-8')
            title = bookMark.get('title').encode('utf-8').replace("'", " ")

            sql = "INSERT INTO bookmark (id,parentId,indexId,url,title) VALUES ('{}','{}','{}','{}','{}')" \
                .format(id, pId, iId, url, title)
            try:
                cursor.execute(sql)
                count = count + cursor.rowcount
            except Exception as e:
                print e
                error = e.message

        cursor.close()
        conn.commit()
    except Exception as e:
        error = e.message
    finally:
        if conn:
            conn.close()
        if count == 0:
            return '{"code":%d,"count":%d,"error":"%s"}' % (-1, count, error)
        else:
            return '{"code":%d,"count":%d,"error":"%s"}' % (0, count, error)
