一、简介

二、代码

#include <Arduino.h>
#include <WiFi.h>
#include <WiFiClientSecure.h>
#include <ArduinoJson.h>// 替换为您的 WiFi 凭据
const char *ssid = "你需要改的地方";
const char *password = "你需要改的地方";// 替换为您的 DeepSeek API 密钥
const char* apiKey = "你需要改的地方";// DeepSeek API 端点
const char* host = "api.deepseek.com";
const int httpsPort = 443;// 创建 WiFiClientSecure 对象
WiFiClientSecure client;// 设置超时时间 (单位：毫秒)
const unsigned long timeout = 10000;// 对话历史
const int maxHistory = 10; // 最大对话轮次
String conversationHistory[maxHistory]; // 存储对话历史
int historyIndex = 0; // 当前对话历史索引// 函数声明
void connectToWiFi();
String askDeepSeek(String question);
void printResponse(String response);
void addToHistory(String role, String content);
void printHistory();void setup() {Serial.begin(115200);// 连接到 WiFiconnectToWiFi();// 关闭证书鉴权client.setInsecure();Serial.println("初始化完成，请输入您的问题：");
}void loop() {// 检查串口是否有输入if (Serial.available()) {String question = Serial.readStringUntil('\n');question.trim(); // 去除换行符和空格if (question.length() > 0) {// 将用户问题添加到对话历史addToHistory("user", question);Serial.println("正在向 DeepSeek 提问...");String response = askDeepSeek(question);printResponse(response);// 将模型回复添加到对话历史addToHistory("assistant", response);// 打印当前对话历史printHistory();Serial.println("\n请输入下一个问题：");}}
}// 连接到 WiFi
void connectToWiFi() {WiFi.begin(ssid, password);while (WiFi.status() != WL_CONNECTED) {delay(1000);Serial.println("正在连接到 WiFi...");}Serial.println("已连接到 WiFi");
}// 向 DeepSeek 提问
String askDeepSeek(String question) {String response = "";// 连接到 DeepSeek APIif (!client.connect(host, httpsPort)) {Serial.println("连接失败");return "连接失败";}// 构建请求String request = "POST /v1/chat/completions HTTP/1.1\r\n";request += "Host: " + String(host) + "\r\n";request += "Authorization: Bearer " + String(apiKey) + "\r\n";request += "Content-Type: application/json\r\n";request += "Connection: close\r\n";// 构建请求体DynamicJsonDocument doc(1024);doc["model"] = "deepseek-chat";doc["stream"] = true;// 添加对话历史JsonArray messages = doc.createNestedArray("messages");for (int i = 0; i < historyIndex; i++) {JsonObject message = messages.createNestedObject();message["role"] = i % 2 == 0 ? "user" : "assistant"; // 交替用户和助手角色message["content"] = conversationHistory[i];}// 添加当前问题JsonObject newMessage = messages.createNestedObject();newMessage["role"] = "user";newMessage["content"] = question;String requestBody;serializeJson(doc, requestBody);request += "Content-Length: " + String(requestBody.length()) + "\r\n\r\n";request += requestBody;// 发送请求client.print(request);// 记录开始时间unsigned long startTime = millis();// 流式接收响应while (client.connected()) {// 检查超时if (millis() - startTime > timeout) {Serial.println("响应超时");break;}// 读取数据while (client.available()) {String line = client.readStringUntil('\n');if (line.startsWith("data: ")) {String jsonData = line.substring(6);DynamicJsonDocument doc(1024);deserializeJson(doc, jsonData);// 提取回复内容if (doc.containsKey("choices")) {String content = doc["choices"][0]["delta"]["content"];response += content;}// 提取思维链内容（假设字段为 "reasoning"）if (doc.containsKey("choices") && doc["choices"][0].containsKey("delta") && doc["choices"][0]["delta"].containsKey("reasoning")) {String reasoning = doc["choices"][0]["delta"]["reasoning"];Serial.println("思维链: " + reasoning);}}}}// 断开连接client.stop();return response;
}// 打印回复内容
void printResponse(String response) {Serial.println("DeepSeek 回复：");Serial.println(response);
}// 添加对话历史
void addToHistory(String role, String content) {if (historyIndex < maxHistory) {conversationHistory[historyIndex] = content;historyIndex++;} else {// 如果历史记录已满，移除最早的记录for (int i = 0; i < maxHistory - 1; i++) {conversationHistory[i] = conversationHistory[i + 1];}conversationHistory[maxHistory - 1] = content;}
}// 打印对话历史
void printHistory() {Serial.println("\n当前对话历史：");for (int i = 0; i < historyIndex; i++) {Serial.println((i % 2 == 0 ? "用户: " : "助手: ") + conversationHistory[i]);}
}

三、实验结果

回复结果为空，deepseek最近的服务器看起来情况不太好啊 - -
