来自已给定图像 Blob URL 的图像 Blob URL

Question

I have a doubt with image blob,is it possible to create an Image blob URL with a given image blob URL? I created a new image blob URL and tried to use it on img tag but it did not work:

    useEffect(() => {
        if (socket.current) {
                socket.current.on("msg-recieve", (msg) => {
                const RecieveBlob = new Blob([msg], { type: 'image/jpeg' });
                const RecieveImageURL = URL.createObjectURL(RecieveBlob);
                console.log("msg recieved is ", msg)
                setArrivalMessage({ fromSelf: false, message: msg })
            })
        }
        setNoImage(false)
    }, [])

In this code, msg is an image blob URL coming from the server and I want to display that image in the page. Therefore, I created new Image blob from it. However, when I use the new Image blob it is not working.

If anybody knows why please help me, Thanks.

If the msg is String you shouldn't wrap that in brackets because it makes it an [String] or Array of strings so try this:

instead of: const RecieveBlob = new Blob([msg], { type: 'image/jpeg' }) ;

write: const RecieveBlob = new Blob(msg, { type: 'image/jpeg' }) ;

PS But I think you can use the blob URL and set it as an image source in the first place, it would work.
