以下是使用 Java 调用 DeepSeek API 的示例。我们将使用 Java 的 HttpURLConnection 或第三方库（如 OkHttp）来发送 HTTP 请求，并处理 API 的响应。
HttpURLConnection 调用 DeepSeek API示例代码
java
复制
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class DeepSeekApiExample {
public static void main(String[] args) {
try {
// DeepSeek API 的 URL
String apiUrl = "https://api.deepseek.com/v1/your-endpoint"; // 替换为实际的 API 端点
// 你的 API 密钥
String apiKey = "your_api_key_here";
// 请求参数
String jsonInputString = "{"text": "这是一个测试文本", "language": "zh", "max_tokens": 50}";
// 创建 URL 对象
URL url = new URL(apiUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
// 设置请求方法为 POST
connection.setRequestMethod("POST");
// 设置请求头
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("Authorization", "Bearer " + apiKey);
// 启用输出流
connection.setDoOutput(true);
// 发送请求
try (OutputStream os = connection.getOutputStream()) {
byte[] input = jsonInputString.getBytes("utf-8");
os.write(input, 0, input.length);
}
// 获取响应代码
int responseCode = connection.getResponseCode();
System.out.println("响应代码: " + responseCode);
// 读取响应
if (responseCode == HttpURLConnection.HTTP_OK) {
try (BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"))) {
StringBuilder response = new StringBuilder();
String responseLine;
while ((responseLine = br.readLine()) != null) {
response.append(responseLine.trim());
}
System.out.println("响应内容: " + response.toString());
}
} else {
System.out.println("请求失败，响应代码: " + responseCode);
}
// 关闭连接
connection.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
}
}
OkHttp 调用 DeepSeek APIOkHttp 是一个流行的 HTTP 客户端库，简化了 HTTP 请求的发送和响应的处理。
添加依赖
在 pom.xml 中添加 OkHttp 依赖：
xml
复制
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>4.9.3</version>
</dependency>
运行 HTML
示例代码
java
复制
import okhttp3.*;
import java.io.IOException;
public class DeepSeekApiExample {
public static void main(String[] args) {
// DeepSeek API 的 URL
String apiUrl = "https://api.deepseek.com/v1/your-endpoint"; // 替换为实际的 API 端点
// 你的 API 密钥
String apiKey = "your_api_key_here";
// 请求参数
String jsonInputString = "{"text": "这是一个测试文本", "language": "zh", "max_tokens": 50}";
// 创建 OkHttp 客户端
OkHttpClient client = new OkHttpClient();
// 创建请求体
RequestBody body = RequestBody.create(jsonInputString, MediaType.parse("application/json"));
// 创建请求
Request request = new Request.Builder()
.url(apiUrl)
.post(body)
.addHeader("Content-Type", "application/json")
.addHeader("Authorization", "Bearer " + apiKey)
.build();
// 发送请求并处理响应
try (Response response = client.newCall(request).execute()) {
if (response.isSuccessful() && response.body() != null) {
String responseBody = response.body().string();
System.out.println("响应内容: " + responseBody);
} else {
System.out.println("请求失败，响应代码: " + response.code());
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
假设 DeepSeek 提供了一个分词 API，以下是如何调用它的示例：
使用 HttpURLConnection
java
复制
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class DeepSeekTokenizeExample {
public static void main(String[] args) {
try {
String apiUrl = "https://api.deepseek.com/v1/tokenize"; // 假设的分词 API 端点
String apiKey = "your_api_key_here";
String jsonInputString = "{"text": "这是一个中文分词测试", "language": "zh"}";
URL url = new URL(apiUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("Authorization", "Bearer " + apiKey);
connection.setDoOutput(true);
try (OutputStream os = connection.getOutputStream()) {
byte[] input = jsonInputString.getBytes("utf-8");
os.write(input, 0, input.length);
}
int responseCode = connection.getResponseCode();
System.out.println("响应代码: " + responseCode);
if (responseCode == HttpURLConnection.HTTP_OK) {
try (BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"))) {
StringBuilder response = new StringBuilder();
String responseLine;
while ((responseLine = br.readLine()) != null) {
response.append(responseLine.trim());
}
System.out.println("分词结果: " + response.toString());
}
} else {
System.out.println("请求失败，响应代码: " + responseCode);
}
connection.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
}
}
使用 OkHttp
java
复制
import okhttp3.*;
import java.io.IOException;
public class DeepSeekTokenizeExample {
public static void main(String[] args) {
String apiUrl = "https://api.deepseek.com/v1/tokenize"; // 假设的分词 API 端点
String apiKey = "your_api_key_here";
String jsonInputString = "{"text": "这是一个中文分词测试", "language": "zh"}";
OkHttpClient client = new OkHttpClient();
RequestBody body = RequestBody.create(jsonInputString, MediaType.parse("application/json"));
Request request = new Request.Builder()
.url(apiUrl)
.post(body)
.addHeader("Content-Type", "application/json")
.addHeader("Authorization", "Bearer " + apiKey)
.build();
try (Response response = client.newCall(request).execute()) {
if (response.isSuccessful() && response.body() != null) {
String responseBody = response.body().string();
System.out.println("分词结果: " + responseBody);
} else {
System.out.println("请求失败，响应代码: " + response.code());
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
使用 HttpURLConnection 是 Java 标准库的方式，无需额外依赖。
使用 OkHttp 更加简洁和高效，适合复杂的 HTTP 请求场景。
根据 DeepSeek 的 API 文档，调整请求参数和处理响应数据。
