今天尝试使用java调用通义千问AL模型，实现图片问答功能，结果在pom.xml中引入最新的dashscope-sdk-java后，按照阿里云官方文档使用流式调用报错：okhttp3/internal/connection/RealCall，在网上搜索无果，经过分析相关功能博主的相关问题博客，终于找到问题根源，特做此记录，希望可以帮助到相关问题的朋友。

阿里云官方调用文档：https://help.aliyun.com/document_detail/2712587.html?spm=a2c4g.2712569.0.i12

1.引入的依赖

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dashscope-sdk-java</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-simple</artifactId>
                </exclusion>
            </exclusions>
            <version>2.14.0</version>
        </dependency>

2.官方流式调用代码：

    public static void streamCall()
            throws ApiException, NoApiKeyException, UploadFileException {
        MultiModalConversation conv = new MultiModalConversation();
        // must create mutable map.
        MultiModalMessage userMessage = MultiModalMessage.builder().role(Role.USER.getValue())
                .content(Arrays.asList(new HashMap<String, Object>(){{put("image", "https://dashscope.oss-cn-beijing.aliyuncs.com/images/dog_and_girl.jpeg");}},
                        new HashMap<String, Object>(){{put("text", "基于这幅图，讲一个故事");}})).build();
        MultiModalConversationParam param = MultiModalConversationParam.builder()
                .model(MultiModalConversation.Models.QWEN_VL_PLUS)
                .message(userMessage)
                .apiKey("you api key")
                .build();
        Flowable<MultiModalConversationResult> result = conv.streamCall(param);
        result.blockingForEach(item -> {
            System.out.println(item);
        });
    }

    public static void main(String[] args) {
        try {
            streamCall();
        } catch (ApiException | NoApiKeyException | UploadFileException e) {
            System.out.println(e.getMessage());
        }
        System.exit(0);
    }

错误原因：

经过分析错误是与项目中的huaweicloud的esdk-obs-java依赖里的okhttp版本冲突了，需注意pom文件里esdk-obs-java依赖在dashscope-sdk-java上方才会冲突，由此推断只要dashscope-sdk-java依赖上方有依赖里包括okhttp版本与dashscope-sdk-java冲突必会出现此问题。

具体如图：
