 Java调用示例（OkHttp + Jackson）

import okhttp3.*;

        ObjectMapper mapper = new ObjectMapper();
        String json = mapper.writeValueAsString(java.util.Map.of(

                .post(RequestBody.create(json, MediaType.get("application/json")))
                .build();

        try (Response response = client.newCall(request).execute()) {
            // 非流式：直接打印 body
            System.out.println(response.body().string());
            // 流式：通过 ResponseBody.source() 逐行读取 SSE，遇 [DONE] 结束
