当OllamaChatClient调用stream流发送重复消息便会报空指针异常 #699

Open Review7872 opened 6 months ago

Review7872 commented 6 months ago

我在使用SpringWebFlux配合OllamaChatClient的stream方法返回大模型响应时如何发送重复的msg程序便会抛出异常。当我给msg添加随意无意义标点符号（与上条消息不一致）便会正常响应，以下是我的代码及异常信息。

===========================================================================

@RestController @RequestMapping("/llama") public class AIChatController { @Resource private OllamaChatClient ollamaChatClient; @GetMapping("/chat") public Flux chat(String msg) { return ollamaChatClient.stream(new Prompt(msg)); } }

======================================================================== 我在后续添加了doOnNext方法视图再次处理用户拿到的消息。此时我仿佛知道了bug为什么出现，此时会打印完所有发送给用户的数据然后报错，所以可能是响应流的结尾数据有什么问题导致最后的序列化出错。如图

@GetMapping("/chat") public Flux chat(String msg) { return ollamaChatClient.stream(new Prompt(msg)).doOnNext(new Consumer() { @Override public void accept(ChatResponse chatResponse) { Generation result = chatResponse.getResult(); System.out.println(result.getOutput().getContent()); } }); } 屏幕截图 2024-05-09 191739
