博客灾备方案（1）：七牛云图床增量同步到GitHub-工具盒子

博客重新备案之后，我一直在思考如何保证博客的灾备方案，想要实现博客的静态部署，脱离服务器和域名。方案已经确认并验证过，这个方案分成两步走，第一步就是保证图床的抽离，不再依赖七牛云这种国内平台。这篇文章来分享一下我实现的七牛云图床同步到GitHub图床。

可行性分析 {#可行性分析}

在确定将 GitHub 当做备用图床的时候，我考虑的问题有以下三点：

GitHub 在国内的访问不稳定，图床访问慢甚至不能访问怎么解决？
GitHub 上传文件比较麻烦，怎么方便的传图？
GitHub 一个项目的空间有限（总空间1G，单文件不超过100M），是否够用？

前两个问题我在分享 GitHub 图床配置的时候已经解决过了，所以不存在问题，而第三个关于空间的问题，我们可以来做一个计算，假设创建一个项目专门存放博客的图片，平均每个图片大概100KB，那么1GB就可以存放1000张，一个博客平均两张也就可以支持500篇文章，一周创建一篇文章的话，500篇文章差不多要10年......看到这些数据，应该不用再担心这小小的1GB是否够用了吧！

我的博客运行了6年多了，文章140多篇，在七牛云空间里面的数据容量也才100M而已，大部分的博文是没有图片的，而且图片本身也不大，所以空间的问题不用太焦虑。

增量同步方案 {#增量同步方案}

图床同步的本质就是将七牛云一个空间里面的全部数据下载后上传到 GitHub 的一个项目中，并且需要保证文件的相对路径一致，这样访问同样一个文件就只需要修改地址的前缀就行。

我的增量同步方案思路如下：

先查询出七牛云空间中所有文件清单，每个文件的相对路径类似 article/2024/20200705192255.png
查询GitHub某个项目中所有文件，输出文件的相对路径类似 article/2024/20200705192255.png
对比两个清单，找出存在七牛云而不存在GitHub中的文件
循环下载七牛云中文件，上传到GitHub中
设置成定时任务，定期执行，实现增量同步

七牛云 SDK 使用 {#七牛云-sdk-使用}

七牛云的 SDK 的使用可以查看官方文档：七牛云 Python SDK

利用七牛云提供的 SDK 实现文件的查询和下载，所以这里实现了两个函数，函数 list_files 用来查询出目标空间下所有的文件，函数 download_file 实现单个文件的下载，封装后的代码如下：

后续我优化了 GitHub 中获取目录文件的逻辑，弃用了递归，直接一个接口搞定：

def list_all_files_v2(self, path=''):
    """
    获取一个目录下所有文件，使用tree接口，而不是递归
    @param path:
    @return:
    """
    files = []
    url = f"https://api.github.com/repos/{self.owner}/{self.repo}/git/trees/{self.branch}?recursive=1"
    headers = {
        "Authorization": f"Bearer {self.token}",
        "Accept": "application/vnd.github.v3+json"
    }
    response = requests.get(url, headers=headers, timeout=20)
    if response.status_code == 200:
        # 解析响应
        result = response.json()
        for item in result["tree"]:
            if item["path"].startswith(path) and item["type"] == "blob":
                files.append(item["path"])
        return files
    else:

我在函数里面添加了一个用来统计执行结果的 result，方便在后续创建成定时任务的时候记录每次的执行结果。

本地调试 {#本地调试}

本地调试只需要传入函数中定义的信息即可，下面是调试代码和执行结果：

调试代码和执行结果

设置成定时任务 {#设置成定时任务}

本地调试OK之后，就可以把这个同步代码放到定时任务中来执行，我博客自带定时任务功能，所以我直接放到了自己的博客的定时任务中，之前也分享过 Django 项目定时任务的创建，这里就简单带过不做详细介绍。

创建定时任务函数 {#创建定时任务函数}

将上述的同步函数导入定时任务的代码中，创建定时任务函数，暴露需要设置的参数：

# name: 指定任务的名称。
# max_retries: 设置任务的最大重试次数
# default_retry_delay: 设置任务重试的默认延迟时间（单位为秒）
# retry_kwargs: 允许为重试指定额外的关键字参数
@shared_task(max_retries=2, default_retry_delay=10)
