请帮我解决这个问题。我使用了 express-formidable npm 而不是 req.body 我使用了 req.fields ，它工作正常但是与另一个使用强大的 npm 的表单数据有冲突。
您的表单元素具有此属性：
enctype="multipart/form-data"
这意味着您发送的请求的内容类型是multipart/form-data。如果删除它，表单将使用默认内容类型，即 x-www-form-urlencoded。 Bodyparser 应该能够解析它。
如果您仍想使用 multipart/form-data（您可以查看 this 关于什么更好的问题），您必须处理某种程度上的其他形式。
顺便说一下，您的代码可能对 SQL injection 来说很脆弱。在进行查询时，我会非常小心地使用字符串连接。您也不必再使用 body-parser 来解析正文。它已经合并到 Express 中，这意味着你可以做
app.use(express.urlencoded({ extended: false }));
app.use(express.json());

我正在尝试向数据库提交表单。这些值没有被提交，而是在数据库上我得到了未定义。基本上我的 req.body 是未定义的，不会传入值。

请帮我解决这个问题。我使用了 express-formidable npm 而不是 req.body 我使用了 req.fields ，它工作正常但是与另一个使用强大的 npm 的表单数据有冲突。
您的表单元素具有此属性：
enctype="multipart/form-data"
这意味着您发送的请求的内容类型是multipart/form-data。如果删除它，表单将使用默认内容类型，即 x-www-form-urlencoded。 Bodyparser 应该能够解析它。
如果您仍想使用 multipart/form-data（您可以查看 this 关于什么更好的问题），您必须处理某种程度上的其他形式。
顺便说一下，您的代码可能对 SQL injection 来说很脆弱。在进行查询时，我会非常小心地使用字符串连接。您也不必再使用 body-parser 来解析正文。它已经合并到 Express 中，这意味着你可以做
app.use(express.urlencoded({ extended: false }));
app.use(express.json());
