2、表单

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>index</title>
</head>
<body>
<form method="post" action="http://localhost:8080/index">
  姓名:  <input type="text" name="name" ><br>
  密码:  <input type="password" name="password"> <br>
    <input type="submit">
</form>
</body>
</html>

3、完整代码

package org.example.kotlin_web

import io.vertx.core.AbstractVerticle
import io.vertx.core.Vertx
import io.vertx.core.buffer.Buffer
import io.vertx.core.json.JsonArray
import io.vertx.core.json.JsonObject
import io.vertx.ext.jdbc.JDBCClient
import io.vertx.ext.web.Router
import io.vertx.ext.web.RoutingContext

class PostHttp :AbstractVerticle(){
    override fun start() {
        var router = Router.router(vertx);
        router.post().path("/index").handler { ctx: RoutingContext ->
            val request = ctx.request()
            val response = ctx.response()
            response.putHeader("Content-Type", "text/plain; charset=UTF-8")
            val formAttributes = request.formAttributes()
            request.bodyHandler { body: Buffer ->
                val formData = body.toString()
                println("Received form data: $formData")
                response.setStatusCode(200)
                response.end("Form submitted successfully")
            }
        }
    }
}

fun main(){
    var vertx = Vertx.vertx();
    val jdbcClient = JDBCClient.createShared(
        vertx, JsonObject()
            .put("url", "jdbc:mysql://localhost:3306/vertxTest")
            .put("driver_class", "com.mysql.cj.jdbc.Driver")
            .put("user", "root")
            .put("password", "123456")
    )
    jdbcClient.getConnection { res ->
        if (res.succeeded()) {
            val connection = res.result()
            val params = JsonArray().add("lisi").add(123)

            connection.queryWithParams("select id from kotlin where name=? and password=?", params) { queryResult ->
                if (queryResult.succeeded()) {
                    val result = queryResult.result()
                    println("成功")
                } else {
                    val error = queryResult.cause()
                    println("失败")
                }

                // 关闭连接
                connection.close()
            }
        } else {
            val error = res.cause()
            println("连接失败")
        }
    }
}

后面该搞ktor了
