解决LangChain4j报错HTTP/1.1 header parser received no bytes

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：

java 复制代码 
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

java 复制代码 
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"));
}
