curl的bash别名函数

Question

I want to setup a bash alias for curl so I only need to pass the file and server url.

I have tried variations of

alias upload='function _upload(){ curl -F 'file=@"$1"' "$2"; };_upload'

without success

I also need to some basic checking when i execute the alias ie if i only do

upload file.txt

it should return "destination server missing" as I haven't entered the server url. Same should be done if the filename is missing.

Don't use aliases for anything complicated. Stick to functions.

upload() {
    [[ "$1" ]] || { echo "Error: Missing file" >&2; return 1; }
    [[ "$2" ]] || { echo "Error: Missing url"  >&2; return 1; }
    curl -F "file=@$1" "$2"
}
