Java 调用示例

使用 OkHttp

import okhttp3.*;
import java.io.IOException;

public class Main {
    public static void main(String[] args) throws IOException {
        OkHttpClient client = new OkHttpClient();
        String apiKey = System.getenv("NEWAPI_API_KEY");

        MediaType JSON = MediaType.get("application/json; charset=utf-8");
        String jsonBody = "{"
                + "\"model\":\"gpt-4.1\","
                + "\"messages\":["
                + "{\"role\":\"developer\",\"content\":\"你是一个有帮助的助手。\"},"
                + "{\"role\":\"user\",\"content\":\"你好！\"}"
                + "]"
                + "}";

        RequestBody body = RequestBody.create(jsonBody, JSON);

        Request request = new Request.Builder()
                .url("https://www.51api.org")
                .addHeader("Content-Type", "application/json")
                .addHeader("Authorization", "Bearer " + apiKey)
                .post(body)
                .build();

        Response response = client.newCall(request).execute();
        System.out.println(response.body().string());
    }
}
