问题描述

当使用langchain4j-open-ai调用自己部署的大模型服务时报错：

public static void main(String[] args) {OpenAiChatModel model = OpenAiChatModel.builder().apiKey("none").modelName("qwen2.5-instruct").baseUrl("http://192.168.0.84:9997/v1").build();System.out.println(model.chat("你好"));
}

报错信息如下：

解决方法

public static void main(String[] args) {HttpClient.Builder httpClientBuilder = HttpClient.newBuilder().version(HttpClient.Version.HTTP_1_1);JdkHttpClientBuilder jdkHttpClientBuilder = JdkHttpClient.builder().httpClientBuilder(httpClientBuilder);OpenAiChatModel model = OpenAiChatModel.builder().httpClientBuilder(jdkHttpClientBuilder).apiKey("none").modelName("qwen2.5-instruct").baseUrl("http://192.168.0.84:9997/v1").build();System.out.println(model.chat("你好"));
