About download messageSender's file

[af913337456]

I am looking for how to download the images in the picture message sent to me by the other party. As for the voice in the voice message. I looked at the function and it doesn't seem to be present. Currently, the "ReadFilePart" function can download its own files. But it seems that the sender cannot download it. Did I miss it? Can you give me some guidance, thank you.

when you listen updates, you can get catch updateType "updateNewMessage", update new message has Message.Content. Message Content has a few types: messageText, messagePhoto and so on. MessagePhoto has Photo. This is your file

they are the basis info, not the body bytes

Have you tried tdlibClient.DownloadFile(...)?

}

we have File.LocalFile.Path

look @af913337456

photoId := contentPhoto.Photo.Sizes[len(contentPhoto.Photo.Sizes)-1].Photo.Id
file, _ := tdlibClient.DownloadFile(&client.DownloadFileRequest{
        FileId:      photoId,
        Priority:    1,
        Offset:      0,
        Limit:       0,
        Synchronous: true,
        })

file.Local.Path - it's your path file. It's located here FilesDirectory: filepath.Join(".tdlib", "files"),
