How to Export variable with spaces in ssh

Question

Bonjour, I'm trying to do something in bash, here is the code :

var1=Hello
var2=I want a coffee
function func () {          
var_temp="alias $1='$2'"          #I need ='' in the result
echo $1
echo $2 
echo $var_temp; }
sshpass -e ssh -q $USER@host "$(declare -f func);func" $var1 $var2

Result $1=Hello
Result $2=I
Result $var_temp=alias Hello='I'

How can I export more than one word in ssh ? Thank you in advance, #be understanding for my english xD

What are you doing with the output of func? If you want to add something to a file, just construct the string locally and pipe it to something like ssh $USER@host 'cat >> the_file'. — chepner

Before worrying about ssh, get the local things fixed: var2=I want a coffee needs quotes or escapes to protect the spaces, and all variable references should be double-quoted (e.g. echo "$var_temp" instead of just echo $var_temp). shellcheck.net is good at pointing out missing double-quotes. As for ssh, my answer here may help. — Gordon Davisson

WIth the output, I want to add string in a file with a sed at a specific lines "after" ``` sudo sed -i "text /a $var_alias" /etc/.....sh ``` — Anthony Lanteri

Try this

#!/usr/bin/env bash
  
var1=Hello
var2="I want a coffee"
func(){                     
    var_temp="alias $1='$2'"      
    echo "$1"
    echo "$2"
    echo "$var_temp"
}
sshpass -e ssh -q $USER@host "$(declare -f func);func" "'$var1'" "'$var2'"
