通过java来进行接口测试，这时候就需要使用java的url类与输入输出流
测试url:https://www.v2ex.com/api/nodes/show.json
参数为：name=python

import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.net.HttpURLConnection;import java.net.MalformedURLException;import java.net.URL;import java.net.URLConnection;public class jiekouTest { public static void main(String[] args) { try { //创建url对象 URL url=new URL("https://www.v2ex.com/api/nodes/show.json?name=python"); //打开一个URL连接，并运行客户端访问资源。 URLConnection urlConnection =(HttpURLConnection)url.openConnection(); urlConnection.connect();//调用URLConnection对象提供的connect方法连接远程服务 InputStream is=urlConnection.getInputStream();//获取输入流访问的资源数据 //通过bufferedReader来读取 BufferedReader buffer=new BufferedReader(new InputStreamReader(is)); StringBuffer bs=new StringBuffer();//存储读取的值 String l=null; //判断读取的值存在则存入StringBuffer while((l=buffer.readLine())!=null) { bs.append(l).append("\n"); } System.out.println(bs.toString()); } catch (MalformedURLException e) { e.printStackTrace(); }catch (IOException e) { e.printStackTrace(); } }}

最后获取到的输出

中文乱码问题解决：
//设置下编码
BufferedReader buffer=new BufferedReader(new InputStreamReader(is,"utf-8"));
