1、账号注册以及获取token

（1）进入api接口文档

（2）充值并创建APIkey

3、添加糊涂工具包

<!--糊涂工具包-->
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>${hutool.version}</version>
</dependency>

4、实体类定义

• ReqMessage

package com.bwie.entity;

import lombok.AllArgsConstructor;
import lombok.Data;

import java.io.Serializable;

@Data
@AllArgsConstructor
public class ReqMessage implements Serializable {
    String role;
    String content;
}

• RequestData

package com.bwie.entity;

import lombok.Data;

import java.io.Serializable;

@Data
public class RequestData implements Serializable {
    String model;
    ReqMessage[] messages;
    boolean stream;
}

• ApiResponse

package com.bwie.entity;

import lombok.Data;

@Data
public class ApiResponse {
    private String id;
    private String object;
    private Long created;
    private String model;
    private Choice[] choices;
    private Usage usage;
}

@Data
class Choice {
    private Integer index;
    private ReqMessage message;
    private String finish_reason;
}

@Data
class Usage {
    private Integer prompt_tokens;
    private Integer completion_tokens;
    private Integer total_tokens;
}

5、请求接口

package com.bwie.controller;

import cn.hutool.http.HttpUtil;
import com.alibaba.fastjson.JSON;
import com.bwie.entity.ReqMessage;
import com.bwie.entity.RequestData;
import com.bwie.utils.R;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.bwie.entity.*;

@RestController
@RequestMapping("/deepSeek")
public class DeepSeekController {

    private static final String API_URL = "https://api.deepseek.com/v1/chat/completions";
    private static final String API_KEY = "sk-1257c8adsfageaasw531bc4c4b3630f3837d";

    @PostMapping("/ask/{question}")
    public R ask(@PathVariable("question") String question) {

        // 构建请求的 JSON 数据
        RequestData requestData = new RequestData();
        requestData.setModel("deepseek-chat");
        requestData.setMessages( new ReqMessage[]{
                new ReqMessage("user", question)
        });
        requestData.setStream( false);


        String postResult = HttpUtil.createPost(API_URL)
                //这个请求头.header是自己项目需要加的，可以省略
                .header("Content-Type", "application/json")
                //这两个请求头是项目需要加的，可以省略
                .header("Authorization", "Bearer " + API_KEY)
                //传输参数
                .body(JSON.toJSONString(requestData))
                .execute()
                .body();
        System.out.println("查询结果："+postResult);

        ApiResponse apiResponse = JSON.parseObject(postResult, ApiResponse.class);

        return R.OK(apiResponse);
    }

}

6、请求结果
