GET request with Java HttpClientSince Java 11, we can use the java.net.http.HttpClient. Main.java import java.io.IOException; import java.net.URI; import java.net.http.HttpClient; import java.net.http.HttpRequest; import java.net.http.HttpResponse; void main() throws IOException, ...

想要回去GET请求中的请求参数,可以直接使用request.getParamMap()方法。但是POST请求的requestBody参数就必须使用流的方式来获取。 BufferedReader reader = null; String body = null; try { reader = new BufferedReader(new InputStreamReader(request.getInputStream())); ...
Java怎么模拟POST请求呢?今天就来说道说道。 一、先说一下get和post GET和POST是HTTP请求的两种基本方法,要说它们的区别,接触过WEB开发的人都能说出一二。 最直观的区别就是GET把参数包含在URL中,POST通过request body传递参数。 1、看一下人畜无害的w3schools怎么说: GET在浏览器回退时是无害的,而POST会再次...
一、Java 11 HttpClient 在Java11的java.net.http.*包中,有一个HttpClient类可以完成HTTP请求。 Java11HttpClientExample.java packagecom.lyl.http; importjava.net.URI; importjava.net.URLEncoder; importjava.net.http.HttpClient; importjava.net.http.HttpRequest; ...
