Java如何获取HTTP响应正文作为字符串?

获取响应正文的实现思路:
      1.引入相应的maven依赖(httpClient)
      2.定义一个httpClient对象
        定义一个httpGet对象
          client.execute(httpget)返回response信息
      
        response.getEntity()返回httpEntity
        EntityUtils.toString(httpEntity); 即可获取正文的字符串

package com.java265.example.httpclient;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

import java.io.IOException;

public class EntityAsString {
    public static void main(String[] args) {
        HttpClient client = HttpClientBuilder.create().build();
        HttpGet request = new HttpGet("https://www.java265.com");

        try {
            HttpResponse response = client.execute(request);
            HttpEntity entity = response.getEntity();

            // 读取实体的内容，并将其作为String返回。
            String content = EntityUtils.toString(entity);
            System.out.println(content);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
