获取群语音下载链接失败

[Aye10032]

问题描述

简要描述一下，现在代码逻辑是先从MessageEvent中通过event.getMessage()方法获得到MessageChain，之后再通过chain.get(OnlineAudio.Key)获得到OnlineAudio的对象，但是通过(audio).getUrlForDownload()拿下载URL的时候如果是群语音就会报错，拿不到，但是如果是私聊发送的语音就可以拿到URL，下载下来解码之后也可以正常播放

直接调用报错的部分

public File getAudioFromMsg(SimpleMsg msg) {
        File silk_file;
        try {
            MessageChain chain = msg.getMsgChain();
            OnlineAudio audio = chain.get(OnlineAudio.Key);
            assert audio != null;

            silk_file = new File(appDirectory + "/origin.silk");
            byte[] bytes1 = IOUtils.toByteArray(new URL((audio).getUrlForDownload()));
            BufferedOutputStream silk_out = new BufferedOutputStream(Files.newOutputStream(silk_file.toPath()));
            silk_out.write(bytes1);
            silk_out.flush();
            silk_out.close();

            File mp3_file;
            AudioUtils.init(new File(appDirectory + "/audio"));
            mp3_file = AudioUtils.silkToMp3(silk_file);

            return mp3_file;
        } catch (MalformedURLException e) {
            throw new RuntimeException(e);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

其中SimpleMsg是自己对消息信息的二次封装，涉及的部分代码如下

    public SimpleMsg(MessageEvent event) {
        if (event instanceof GroupMessageEvent) {
            type = MsgType.GROUP_MSG;
            fromGroup = ((GroupMessageEvent) event).getGroup().getId();
        } else if (event instanceof FriendMessageEvent) {
            type = MsgType.PRIVATE_MSG;
        } else if (event instanceof GroupTempMessageEvent) {
            type = MsgType.PRIVATE_MSG;
        }
        fromClient = event.getSender().getId();
        msg = getMsgFromEvent(event);
        msgChain = event.getMessage();
        this.event = event;
    }

    /**
     * 获取MessageChain对象 用于处理非文本信息
     * @return MessageChain对象
     */
    public MessageChain getMsgChain() {
        return msgChain;
    }

只有群聊中的语音信息会出现问题

复现

1. 从MessageEvent中通过event.getMessage()方法获得到MessageChain
2. 通过chain.get(OnlineAudio.Key)获得到OnlineAudio的对象
3. 通过(audio).getUrlForDownload()获取下载链接
4. 在群聊中发送语音触发事件，报错，Could not fetch URL for audio

我这边是用的Android TIM
刚才用Android QQ试了下也报错，PC没用试

同序列化 MessageChain.serializeToJsonString(messages); 也会偶发.
