Node.js 为什么我在提交添加输入的表单时会收到400错误请求？
背景：我有一个基于node/express的web应用程序，它基本上是露营地的评级/数据库网站。您可以在此处查看当前工作版本，并在此处查看github:。我刚刚完成了添加用户配置文件的尝试，方法是更新注册表单以包含更多信息，并为每个用户添加一个显示页面。现在，每当我点击注册按钮（或使用邮递员发送post请求/注册），我都会收到一个400错误请求。然后，如果我转到主页，我可以作为我尝试注册的用户登录，这样即使出现错误的请求，该用户也可以注册。我已经尝试过清除缓存和浏览历史记录，并使用其他浏览器，但仍然不起作用。我甚至尝试删除我对表单所做的所有更改，使其再次成为用户名和密码，但仍然无法正常工作。我已经试着修复这个问题并调试了几个小时，但我无法理解会发生什么 这是我的注册页面：Node.js 为什么我在提交添加输入的表单时会收到400错误请求？,node.js,express,routes,http-status-code-400,bad-request,Node.js,Express,Routes,Http Status Code 400,Bad Request,背景：我有一个基于node/express的web应用程序，它基本上是露营地的评级/数据库网站。您可以在此处查看当前工作版本，并在此处查看github:。我刚刚完成了添加用户配置文件的尝试，方法是更新注册表单以包含更多信息，并为每个用户添加一个显示页面。现在，每当我点击注册按钮（或使用邮递员发送post请求/注册），我都会收到一个400错误请求。然后，如果我转到主页，我可以作为我尝试注册的用户登录，这样即使出现错误的请求，该用户也可以注册。我已经尝试过清除缓存和浏览历史记录，并使用其他浏览器，但

你能显示你的注册路径吗？@RaviShankarBharti这是“handle signup logic”下的代码块，该代码块以router.post（“/register”）开头你能在模式中显示你的User.register方法吗？@RaviShankarBharti我已经编辑了这个问题以包含用户模式。这个方法来自passport local mongoose。你能显示你的注册路径吗？@RaviShankarBharti它是“handle signup logic”下的代码块，以router.post（“/register”）开头你能在模式中显示你的User.register方法吗？@RaviShankarBharti我已经编辑了这个问题以包含用户模式。该方法来自passport local mongoose。
