1、deepseek介绍

DeepSeek（深度求索）是一家成立于2023年7月的中国人工智能公司，由量化资管巨头幻方量化创立，专注于开发高性能大语言模型（LLM）及相关技术。今年年初以其模型高性能能力而备受关注，目前国内企业正在广泛接入使用。

2、vue前端界面

加了一个nav页签:深度探索
页面代码如下：

<template><div class="chat-wrapper"><div class="chat-container"><div class="chat-header"><h2>DeepSeek 对话</h2></div><div class="chat-messages" ref="chatMessages"><div v-for="(message, index) in chatMessages" :key="index" :class="['message', message.includes('你:') ? 'user-message' : 'bot-message']"><span>{{ message }}</span></div></div><div class="input-container"><input v-model="userInput" type="text" placeholder="输入你的问题" @keydown.enter="sendMessage"><button @click="sendMessage">发送</button></div></div></div>
</template><script>
export default {data() {return {userInput: '',chatMessages: []};},methods: {async sendMessage() {if (this.userInput.trim() === '') return;// 显示用户消息this.chatMessages.push(`你: ${this.userInput}`);try {//这里后面换成服务器ipconst response = await fetch('http://localhost:8090/deepseek', {method: 'POST',headers: {'Content-Type': 'application/json'},body: JSON.stringify({ prompt: this.userInput })});const data = await response.json();const answer = data.answer;// 显示 DeepSeek 的回答this.chatMessages.push(`DeepSeek: ${answer}`);} catch (error) {console.error('请求出错:', error);this.chatMessages.push('请求出错，请稍后再试');}// 清空输入框this.userInput = '';this.$nextTick(() => {this.$refs.chatMessages.scrollTop = this.$refs.chatMessages.scrollHeight;});}}
};
</script><style scoped>
.chat-wrapper {display: flex;justify-content: center;align-items: center;min-height: 100vh;background-color: #f4f4f9;
}.chat-container {width: 80%;height: 80vh;border-radius: 12px;box-shadow: 0 4px 20px rgba(0, 0, 0, 0.1);background-color: #fff;overflow: hidden;display: flex;flex-direction: column;
}.chat-header {background-color: #007bff;color: #fff;padding: 15px 20px;text-align: center;flex-shrink: 0;
}.chat-header h2 {margin: 0;font-size: 1.3rem;
}.chat-messages {flex-grow: 1;overflow-y: auto;padding: 20px;display: flex;flex-direction: column;
}.message {padding: 10px 15px;border-radius: 8px;margin-bottom: 10px;max-width: 80%;word-wrap: break-word;
}.user-message {background-color: #e0f7fa;align-self: flex-end;color: #212121;
}.bot-message {background-color: #f1f8e9;align-self: flex-start;color: #212121;
}.input-container {display: flex;padding: 15px 20px;border-top: 1px solid #e0e0e0;flex-shrink: 0;
}.input-container input {flex: 1;padding: 10px;border: 1px solid #ccc;border-radius: 6px;margin-right: 10px;font-size: 1rem;
}.input-container button {padding: 10px 20px;background-color: #007bff;color: #fff;border: none;border-radius: 6px;cursor: pointer;font-size: 1rem;transition: background-color 0.2s ease;
}.input-container button:hover {background-color: #0056b3;
}
</style>

3、deepseek api申请

deepseek api
申请完之后，需要充值使用，有的新人会有免费使用次数，我这里充值了5米，测试用够了。

4、springboot接口增加

DeepSeekController接口

package top.naccl.controller;
import com.fasterxml.jackson.databind.JsonNode;
import okhttp3.*;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import top.naccl.model.dto.DeepSeekRequest;
import top.naccl.model.dto.DeepSeekResponse;
import com.fasterxml.jackson.databind.ObjectMapper;import java.io.IOException;
import java.util.concurrent.TimeUnit;@RestController
public class DeepseekController {private static final ObjectMapper objectMapper = new ObjectMapper();//换成自己的deepseek apiprivate static final String DEEPSEEK_API_KEY = "sk-xxxx";private static final String DEEPSEEK_API_URL = "https://api.deepseek.com/v1/chat/completions";@PostMapping("/deepseek")public DeepSeekResponse handleDeepSeekRequest(@RequestBody DeepSeekRequest request) throws IOException {OkHttpClient client = new OkHttpClient.Builder().readTimeout(100, TimeUnit.SECONDS)  // 增加读取超时时间.build();MediaType JSON = MediaType.get("application/json; charset=utf-8");String json = "{\"model\": \"deepseek-chat\", \"messages\": [{\"role\": \"user\", \"content\": \"" + request.getPrompt() + "\"}]}";// 使用 okhttp3.RequestBody 创建请求体okhttp3.RequestBody body = okhttp3.RequestBody.create(JSON, json.getBytes());Request apiRequest = new Request.Builder().url(DEEPSEEK_API_URL).post(body).addHeader("Authorization", "Bearer " + DEEPSEEK_API_KEY).addHeader("Content-Type", "application/json").build();try (Response response = client.newCall(apiRequest).execute()) {if (!response.isSuccessful()) {return new DeepSeekResponse("请求失败：" + response.code());}return handleNormalResponse(response);} catch (IOException e) {return new DeepSeekResponse("请求异常：" + e.getMessage());}}private DeepSeekResponse handleNormalResponse(Response response) throws IOException {try (ResponseBody body = response.body()) {if (body == null) {return new DeepSeekResponse("空响应");}String responseData = body.string();JsonNode jsonNode = objectMapper.readTree(responseData);if (jsonNode.has("choices") && !jsonNode.get("choices").isEmpty()) {JsonNode messageNode = jsonNode.get("choices").get(0).get("message");if (messageNode != null && messageNode.has("content")) {return new DeepSeekResponse(messageNode.get("content").asText());}}return new DeepSeekResponse("未找到有效回答");}}}

DeepSeekRequest请求类

package top.naccl.model.dto;import com.fasterxml.jackson.annotation.JsonProperty;// 请求类，用于接收前端传来的用户问题
public class DeepSeekRequest {@JsonProperty("prompt")private String prompt;public String getPrompt() {return prompt;}public void setPrompt(String prompt) {this.prompt = prompt;}
}

DeepSeekResponse响应类

package top.naccl.model.dto;// 响应类，用于返回 DeepSeek 的回答给前端
public class DeepSeekResponse {private String answer;public DeepSeekResponse(String answer) {this.answer = answer;}public String getAnswer() {return answer;}public void setAnswer(String answer) {this.answer = answer;}
}

5、pom.xml引入

    <!-- deepseek --><dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>4.11.0</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId></dependency>
