username	13311112222	手机号。
password	sssss	明文密码。
courseId	406	课程ID
keyPrefix	bennie	用于redis中key的前缀。为空时为当前时间戳。（可选）
token	a-iQ_qHLYe7Lp7p2GDeNT8_CnZg25CQ4-1637546627	访问Token。`long=false`时需提供该值。可从登录接口响应`token`字段中获取。
userId	10740728	用户ID。`long=false`时需提供该值。可从登录接口响应`id`字段中获取。

支持通过java -jar -Dkey=value方式传值。实际上，程序中以System.getProperty("key")方式读取配置值。

提交单元视频的学习时间点

分两种情况：

播放新视频。
继续已播放视频。

提交视频播放时间点，最好是120秒提交一次，否则会检测到频繁提交，在程序中可以设置延迟。

如果是新播放的视频，那么初次提交时间从0开始，继续播放的视频，提交时间可以从当前播放时间120秒后开始。当前视频的播放时间的progress_time属性可以获取单元的video信息的接口响应中取得。

播放新视频

首次播放：

注意，参数time=0&start=1，time从0开始，并且多出start=1参数。

继续已播放视频

例如一个视频321秒，之前未播放完，接下来继续播放，那么提交参数时，可以从当前播放视频的时间点追加120秒继续播放，然后继续提交至视频总时长即可。

继续提交时间时不需要提供start=1参数。

标记图文单元已完成
