vertx的学习总结7之用kotlin 与vertx搞一个简单的http
这里我就简单的聊几句，如何用vertx web来搞一个web项目的
1、首先先引入几个依赖，这里我就用maven了，这个是kotlin+vertx web

</project>2、先创建一个简单的httpweb
package org.example.kotlin_web
import io.vertx.core.AbstractVerticle
import io.vertx.core.Vertx
import io.vertx.core.http.HttpServerOptions
import io.vertx.ext.web.Router
import kotlinx.coroutines.delay
class HttpWeb : AbstractVerticle() {
override fun start() {
var router = Router.router(vertx);
router.get("/hello").handler { context ->
context.response().end("Hello World")
};
vertx.createHttpServer().requestHandler(router).listen(8080)
}
}
fun main(){
var vertx = Vertx.vertx();
vertx.deployVerticle(HttpWeb())
}这里用了路由，也就是说访问localhost:8080/hello 它会输出Hello World，这个是get请求
3、get请求带参数
package org.example.kotlin_web
import io.vertx.core.AbstractVerticle
import io.vertx.core.Vertx
import io.vertx.ext.web.Router
class HttpWeb : AbstractVerticle() {
override fun start() {
var router = Router.router(vertx);
router.get("/hello").handler { ctx ->
val name: String = ctx.request().getParam("name")
// 处理逻辑
val message = "Hello, $name!"
// 返回响应
ctx.response().end(message)
};
vertx.createHttpServer().requestHandler(router).listen(8080)
}
}
fun main(){
var vertx = Vertx.vertx();
vertx.deployVerticle(HttpWeb())
}可以看到非常简单
4、post请求带参数
package org.example.kotlin_web
import io.vertx.core.AbstractVerticle
import io.vertx.core.Vertx
import io.vertx.core.buffer.Buffer
import io.vertx.ext.web.Router
import io.vertx.ext.web.RoutingContext
import io.vertx.ext.web.handler.StaticHandler
class HttpWeb : AbstractVerticle() {
override fun start() {
var router = Router.router(vertx);
router.route().handler(StaticHandler.create("src/main/resources/static").setCachingEnabled(false).setDefaultContentEncoding("UTF-8"));
router.get("/hello").handler { ctx ->
val name: String = ctx.request().getParam("name")
// 处理逻辑
val message = "Hello, $name!"
// 返回响应
ctx.response().end(message)
};
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")
}
}
vertx.createHttpServer().requestHandler(router).listen(8080)
}
}
fun main(){
var vertx = Vertx.vertx();
vertx.deployVerticle(HttpWeb())
}
index.html
<!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>这里的所有代码都写到了同一个文件里面，这样极其的不美观，可以优化一下
