提示：今天主要学习了使用Hutool的方式来发送Http请求

---

一、导库

        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>5.8.26</version>
        </dependency>

二、使用

package com.yupi.yuapiinterface.client;

import cn.hutool.http.HttpRequest;
import cn.hutool.http.HttpResponse;
import cn.hutool.http.HttpUtil;
import cn.hutool.json.JSONUtil;
import com.yupi.yuapiinterface.model.User;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestParam;

import java.util.HashMap;

/**

public class YuApiClient {

    public String getNameByGet(String name) {
        //可以单独传入http参数，这样参数会自动做URL编码，拼接在URL中
        HashMap<String, Object> paramMap = new HashMap<>();
        paramMap.put("name", name);

        String result3= HttpUtil.get("http://localhost:8123/api/name/", paramMap);
        System.out.println(result3);
        return result3;
    }

    public String getNameByPost(@RequestParam String name) {
        HashMap<String, Object> paramMap = new HashMap<>();
        paramMap.put("name", name);
        String result= HttpUtil.post("http://localhost:8123/api/name/", paramMap);
        System.out.println(result);
        return result;
    }

    public String getUserNameByPost(@RequestBody User user) {
        String json = JSONUtil.toJsonStr(user);
        HttpResponse httpResponse = HttpRequest.post("http://localhost:8123/api/name/user").body(json).execute();
        System.out.println(httpResponse.getStatus());
        String result = httpResponse.body();
        return result;
    }

}

三、调用

YuApiClient yuApiClient = new YuApiClient();
        String result = yuApiClient.getNameByGet("贺浩浩");
        String result1 = yuApiClient.getNameByPost("星轨");
        User user = new User();
        user.setUsername("星轨xxx");
        String result2 = yuApiClient.getUserNameByPost(user);
        System.out.println(result);
        System.out.println(result1);
        System.out.println(result2);

四、结果
