建设工程规划许可证查询网站集合竞价口诀背熟6句
1.deepseek的api创建
deepseek官网链接
点击右上API开放平台后找到API keys 创建APIkey：
注意：创建好的apikey只能在创建时可以复制，要保存好
2.java实现请求deepseek
使用springboot+maven
2.1 pom文件：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.4.2</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.demo</groupId><artifactId>deepseek-java</artifactId><version>0.0.1-SNAPSHOT</version><name>deepseek-java</name><description>Demo project for Spring Boot</description><properties><java.version>21</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>RELEASE</version><scope>compile</scope></dependency><dependency><groupId>org.json</groupId><artifactId>json</artifactId><version>20231013</version></dependency><dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>4.12.0</version></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build><repositories><repository><id>maven-ali</id><url>http://maven.aliyun.com/nexus/content/groups/public//</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled><updatePolicy>always</updatePolicy><checksumPolicy>fail</checksumPolicy></snapshots></repository></repositories><pluginRepositories><pluginRepository><id>public</id><name>aliyun nexus</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><releases><enabled>true</enabled></releases><snapshots><enabled>false</enabled></snapshots></pluginRepository></pluginRepositories></project>
2.2 json转化文件：
参数可以参考DeepSeek API 文档
import org.json.JSONArray;
import org.json.JSONObject;/*** @Description:自定义json转化* @Author:* @Date: 2025/2/20* @Version: v1.0*/
public class JsonExample {/*** toJson* @param msg 你要输入的内容* @param model 模型类型 例如 deepseek-chat、deepseek-reasoner* @return 组装好的json数据*/public static String toJson(String msg,String model){// 创建JSON对象JSONObject json = new JSONObject();// 创建messages数组JSONArray messages = new JSONArray();// 添加第一个messageJSONObject systemMessage = new JSONObject();systemMessage.put("content", "You are a helpful assistant");systemMessage.put("role", "system");messages.put(systemMessage);// 添加第二个messageJSONObject userMessage = new JSONObject();userMessage.put("content", msg);userMessage.put("role", "user");messages.put(userMessage);// 将messages数组添加到JSON对象json.put("messages", messages);// 添加其他字段json.put("model", model);json.put("frequency_penalty", 0);json.put("max_tokens", 2048);json.put("presence_penalty", 0);// 添加response_format对象JSONObject responseFormat = new JSONObject();responseFormat.put("type", "text");json.put("response_format", responseFormat);// 添加其他字段json.put("stop", JSONObject.NULL);json.put("stream", false);json.put("stream_options", JSONObject.NULL);json.put("temperature", 1);json.put("top_p", 1);json.put("tools", JSONObject.NULL);json.put("tool_choice", "none");json.put("logprobs", false);json.put("top_logprobs", JSONObject.NULL);// 控制台打印输出JSON字符串并且使用2个空格进行缩进//System.out.println(json.toString(2));return json.toString();}
}
转化后JSON如下：
{"messages": [{"content": "You are a helpful assistant","role": "system"},{"content": "Hi","role": "user"}],"model": "deepseek-chat","frequency_penalty": 0,"max_tokens": 2048,"presence_penalty": 0,"response_format": {"type": "text"},"stop": null,"stream": false,"stream_options": null,"temperature": 1,"top_p": 1,"tools": null,"tool_choice": "none","logprobs": false,"top_logprobs": null
}2.2 实现类：
import okhttp3.*;import java.io.IOException;/*** @Description:* @Author:* @Date: 2025/2/20* @Version: v1.0*/
public class MyDeepSeekClient {private static final String API_URL = "https://api.deepseek.com/chat/completions"; // 替换为实际的API URLprivate static final String API_KEY = "你的APIkey"; // 替换为实际的API密钥public static void main(String[] args) {try {String json = JsonExample.toJson("你好", "deepseek-chat");OkHttpClient client = new OkHttpClient().newBuilder().build();MediaType mediaType = MediaType.parse("application/json");RequestBody body = RequestBody.create(mediaType, json);Request request = new Request.Builder().url(API_URL)//deepseek的API.method("POST", body).addHeader("Content-Type", "application/json").addHeader("Accept", "application/json").addHeader("Authorization", "Bearer "+API_KEY)//deepseek的API_KEY.build();// 异步发送 POST 请求client.newCall(request).enqueue(new Callback() {@Overridepublic void onFailure(Call call, IOException e) {e.printStackTrace();}@Overridepublic void onResponse(Call call, Response response) throws IOException {try {if (response.isSuccessful()) {//判断响应是否成功// 成功System.out.println("状态码: " + response.code());System.out.println("响应体: " + response.body().string());} else {// 失败System.out.println("状态码: " + response.code());System.out.println("响应体: " + response.body().string());}} finally {// 关闭响应体，防止资源泄漏response.close();}}});} catch (Exception e) {e.printStackTrace();}}
}
输入结果如下：
状态码: 200
响应体: {"id":"6d83333a-ac8e-4ebf-9030-dc4e5ec620a3","object":"chat.completion","created":1740040067,"model":"deepseek-chat","choices":[{"index":0,"message":{"role":"assistant","content":"你好！很高兴见到你。有什么我可以帮忙的吗？"},"logprobs":null,"finish_reason":"stop"}],"usage":{"prompt_tokens":9,"completion_tokens":11,"total_tokens":20,"prompt_tokens_details":{"cached_tokens":0},"prompt_cache_hit_tokens":0,"prompt_cache_miss_tokens":9},"system_fingerprint":"fp_3a5770e1b4"}注意事项：
-
响应体大小：如果响应体较大，直接调用
responseBody.string()可能会占用大量内存。对于大文件或流式数据，可以使用responseBody.byteStream()或responseBody.charStream()。
