ThinkPHP6.x的COOKIE中总是带有：thinkphp_show_page_trace=0|0
问题描述
ThinkPHP6.x的cookie中总带：thinkphp_show_page_trace=0|0，不但容易暴露后台服务器使用了ThinkPHP，而且对于强迫症的程序员工来说总是感觉心里太不爽了。

产生的原因
这个是开启trace页面调试跟踪后造成的，也是说在.env文件中设置了“APP_DEBUG = true”。
APP_DEBUG = true
[APP]
DEFAULT_TIMEZONE = Asia/Shanghai
解决方案
在.env文件中设置“APP_DEBUG = false”,并且关闭浏览器，必要时可以清空一下浏览器缓存。
APP_DEBUG = false
[APP]
DEFAULT_TIMEZONE = Asia/Shanghai
这回瞬间感觉爽了许多~~！
