MV下载出错

[Mr-z-j]

main.rs文件中

let extension = match download_url.rfind(".") { None => typ.as_str(), Some(index) => &download_url[index..], };

因mv后缀增加了密钥参数，所以mp4扩展名取错，创建文件时卷标报错

我把这里改了 let filename = match typ.as_str() { "mp3" => format!("{}{}", song.file_name(&fmt), ".mp3"), "mv" => format!("{}{}", song.filename(&fmt), ".mp4"), => unreachable!(), };
