我有一个使用FLASK和Python运行的网页,并且连接了一个数据库sqlite3。我创建了一个名为guestbook的页面,我要求用户输入一些关于它们的详细信息:Name,Email,Age,以及将该信息发送到服务器和数据库。我正在页面上检索它以显示用户的输入。
这里的整个代码几乎都是从讲座中复制/粘贴的,因为讲师向我们展示了代码以及它如何逐件工作,然后由我们将它粘合在一起。因此,当我比较它们看起来相同的代码时,我的错误就是我的错误而且我没有看到错误。我没有任何拼写错误,文件名称正确,行与我的讲师完全相同。如果你能指出我的错误,我将不胜感激。
当我运行python文件时它运行正常,或者至少我认为是运行python文件的打印屏幕
如果页面没有加载,并且令人困惑的是,在命令窗口中我无法看到自激活调试器后的错误,它通常会写入错误。所以我迷失了哪里是错误,因为我不知道在哪里看。
内部服务器错误

答案 0 :(得分:0)
将frameinput.pack(side=LEFT, fill=BOTH, expand=YES)
中的method = post
更改为<form action
。完整的行应该是:
method='POST'
