问题1

wfc.sendMessage(msg, (messageId) => { msg.messageId = messageId; console.log('sf', messageId , 'prepared') }, (progress, total) => { console.log('sf', msg.messageId , 'progress') console.log('sf', msg.messageId, Math.ceil(progress / total * 100),'progress') let sm = conversationState.sendingMessages.find(e => e.messageId === msg.messageId); if (sm) { sm.progress = progress; sm.total = total; } else { conversationState.sendingMessages.push({ messageId: msg.messageId, progress, total }); } }, (messageUid) => { console.log('sf', messageUid,' success') conversationState.sendingMessages = conversationState.sendingMessages.filter(e => e.messageId !== msg.messageId); }, (error) => { console.log('sf', error.messageId, error,'error') conversationState.sendingMessages = conversationState.sendingMessages.filter(e => e.messageId !== msg.messageId); } );

调用发送函数，发送图片，控制台日志sdk打印了 publish response GMPU proto.min.js:1 publish response error b0.exports {cmd: 'puback', retain: false, qos: 0, dup: false, length: 371, …}cmd: "puback"dup: falselength: 371messageId: 57055payload: nullqos: 0reasonCode: 10retain: falsetopic: null[[Prototype]]: Object proto.min.js:1 getUploadMediaUrl e -1

出现这种情况，wfc.sendMessage 没有任何回调，消息的状态也没有改变，一直是在发送中的状态

问题2

发送消息，消息状态有时候会回调失败，但是接收者会收到消息。
