保存vx文章到pdf文件
本帖最后由 helian147 于 2021-1-24 14:26 编辑目的：
保存一些零散公众号文章到pdf，不是采集某个公众号全部文章【可以用夜泉大神的WeChatDownload，论坛有下载】。
这程序没啥用，会的无须用嘛{:1_911:}
实现：
1、复制公众号链接【试了几次发现拷贝到QQ，登陆PC QQ再复制全部链接比较方便】链接全部复制到指定txt文件，txt文件内容无需排版、会自动提取链接；
2、运行程序，pdf保存在指定目录。
需要修改：
1、txt文件的目录，由path参数指定，默认桌面
2、pdf保存在指定目录path下的pdf目录，不存在会新建pdf目录，也可自己修改
3、options选项：page-size指定页面大小；zoom指定缩放【有时文章带CODE太长而打印PDF不全，可以缩放试试】，pdf打印出来效果可以调整试试。
感谢论坛大神【收藏夹太多没找到{:1_925:}】，代码大部分是参考的【拷贝的:victory:】
