命令行推送文章到博客园

利用Python从命令行向博客园推送文章

下面的代码可以利用博客园的metawebblog向其推送文章，而不用每次很麻烦的复制文章到浏览器。

首先需要准备一个如下形式的json配置文件：

{
    "url": "https://rpc.cnblogs.com/metaweblog/username",
    "appkey": "username",
    "usr": "username",
    "passwd": "pwd",
}

配置文件中的username都改为你自己的用户名(url最后面的也别忘了)，pwd改为密码。

第一次运行本程序可以试一下 python publish.py -h 查看每个命令行参数表示什么意思。

然后就可以方便地推送文章到博客园啦！
