问题：如果获取到请求正文username和password信息？

老师，有时候按回车键，是换行  而不是不能得到相应的结果 

这个是什么原因呢

老师，我按照例子上边代码敲的，但是图片不能正常展示，为什么呀？

请问这个是虚拟机的问题吗，我没有装rabbitmq啊

老师，我这每次第一次死的时候不爆炸，第二次开始才爆炸，但是爆炸一闪而过。麻烦帮看一下，谢谢

老师创建表，显示成功了，也有了，但是在navicat 里面不显示，怎么解决

视图解析器配置的后缀是.jsp，但是freemarker文件的后缀是.ftl，为什么可以运行？

老师，图中，抱歉，是由橙色文字来定性的吗？还是有引号里面的绿色文字定性的？

引号之中的可以修改吗？

老师好，这里的if __name=="__main__"

可以理解为是终止循环的一个判断条件吗

即导入模块进行执行，判断变量名不等于main，因此就避免递归

请问为什么要引入lamda表达式，相对于传统的函数调用，带来什么好处？

老师，这个问题怎么解决呢。好像是注册表不对吧。
