在 “Deploy to Heroku” 之后手动更新Heroku应用
这个tips以RSSHub为例子。我在Heroku上部署了RSSHub用以日常RSS需求，这个已经部署很久了（2018年11月），准备更新一版，记录如下。
- 登录Heroku，按照提示进行认证并登录。
$ heroku login
- 获取最新代码，这里我在RSSHub项目目录中进行了拉取（pull）：
$ cd RSSHub
$ git pull origin master
- 添加Heroku中项目url，可在
Settings中Heroku Git URL找到：
$ heroku git:remote -a rss-qiwihui
set git remote heroku to https://git.heroku.com/rss-qiwihui.git
- 向Heroku推送，这时Heroku会自动进行部署，结果如下：
$ git push heroku master

前往相应的页面验证，可以看到在Debug中的 githash值已经是当前最新的hash值了。
