});请帮我解决这个问题。我使用了快速强大的npm而不是req.body，我使用的req.fields工作正常，但是与另一个使用强大的npm的表单数据存在冲突。
您在表单元素上有此属性：
enctype="multipart/form-data"
这意味着您要发送的请求的内容类型是multipart / form-data。如果删除它，表单将使用默认的内容类型，即x-www-form-urlencoded。 Bodyparser应该能够解析它。
如果你仍然想使用multipart / form-data（你可以看一下关于什么更好的this问题），你必须以某种方式处理其他形式。
顺便说一下，你的代码可能对SQL injection来说很弱。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来解析实体。它被合并到Express中，这意味着你可以做到
app.use(express.urlencoded({ extended: false }));
app.use(express.json());
