我有一个heroku应用程序（whatever-app-11123），我想通过ssl（https://myapp.co）使用自定义域。
我已经购买了证书，并按照heroku提供的所有说明进行操作。
奇怪的是，https://whatever-app-11123显示myapp.co证书，而https://myapp.co显示* .herokuapp.com证书。
我需要相反的方法：带有myapp.co证书的myapp.co。
关于如何实现这一目标的任何提示？
不同命令的结果：
herok：证书

最佳答案
答案是：检查您的DNS重定向。确保它是CNAME类型，而MOST OF ALL（我做错了）的重定向应该是：
www.myapp.co -> whatever-app-11123.herokuapp.com
myapp.co -> whatever-app-11123.herokuapp.com
并不是
www.myapp.co -> myapp.co
myapp.co -> whatever-app-11123.herokuapp.com
