Im web demo invite end hang up error avoidance

From now on Downloaded from the official website IM web End Demo If you send an invitation and hang up, the following error will be reported , This will cause the hang up exception , So how does this problem arise and how to avoid it ？

The invitation end hangs up abnormally

Cause analysis

Print as shown in the following figure res We know the value of trtcCalling hangup Method returns a with no return value promise, An error will be reported if the value is taken later , Cause exception

Print res value

return undefined

So is it normal for us to comment out this value , After testing . Note that you can hang up normally , But there is a problem , The page after hang up does not show hang up （ Cancel the call ） The news of

Comment out value

Message display exception

You can see from the commented out code logic , The reason for taking this value is to put this message pusher To the message list . But how can I get and add the return value without it at present .

Avoid scheme

At present, there seems to be no good way to take values , We can only save the country by curving . I think that as long as the hang up signaling is successfully sent , You can pull the message list again . So I refreshed the next page and pulled the message list after logging in again , Sure enough, I got it .

Log out and pull the message list again , Normal pulling

There is no need to show off here , Adjust directly after hanging up getMessageList Since the message list is not updated, the direct call will report ’ No more news ‘ A hint of , After the test, the callback after the hang up succeeds is added with this.$store.dispatch('checkoutConversation', this.currentConversation.conversationID) The message display is normal after hanging up .

Add the exception logic to avoid message presentation

Message display is normal

thus , This problem is perfectly avoided , If it helps you , Please give me a compliment ！
