我正在尝试向数据库提交表单。值不提交,而是在数据库上我未定义。基本上我的req.body是未定义的,并且不会传递值。

var http = require('http');
//var formidable = require("express-formidable");
var path    = require("path");
var shell = require('shelljs');
var formidable = require('formidable');
app.use(express.static('Project'));

app.use(bodyParser.json());

app.use(bodyParser.urlencoded({
    extended: false
}));
var mysqlConnection = getConnection();

function getConnection() {
    return mysql.createConnection({

    });
    
}
app.post('/submit', (req, res) => {
    console.log("entered");
    console.log('line', req.body.line);
    var form = new formidable.IncomingForm();
    var application = req.body.namel;
    console.log("appli", req.body.namel);

请帮助我解决该问题。我使用express-formidable npm,而不是req.body,我使用的req.fields正常工作,但是与另一个使用强大npm的表单数据存在冲突。

您在表单元素上具有此属性:

enctype="multipart/form-data"

这意味着您要发送的请求的内容类型为 multipart / form-data 。如果将其删除,则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。

如果您仍想使用 multipart / form-data (您可以查看this有关更好的问题),则必须以某种方式处理其他形式

顺便说一句,您的代码可能不适合SQL injection。在进行查询时,我会非常小心使用字符串连接。您也不必再使用body-parser来解析正文。它已经合并到Express中,这意味着您可以做到

app.use(express.urlencoded({ extended: false }));
app.use(express.json());
