How to use shell parallel with two files

Question

I want to use parallel in this example:

cat codigos.txt | parallel -j 10 "wget http://mywebsite.com/teste?id={}&x=&date=01/01/2017" --load-cookies=cookies.txt

I have three files: codigos.txt, a file with the ids, dates.txt, a file with the dates and cookies.txt the file with the cookie that I need to do the request.

What I want to do is to save the response from mywebsite.com for each url, using the contents of my files.

Problems:

1. How do I do to use information coming from two files?
2. The url is cut at the '&' (even when I put the quotes). Example:

request made to http://mywebsite.com/teste?id=1

As this example (but without put the space or cut because of the '&'):

cat abc-file | parallel -a - -a def-file echo

I assume you want to run:

wget http://mywebsite.com/teste?id=codigo1&x=&date=01/01/2017" --load-cookies=cookies.txt
wget http://mywebsite.com/teste?id=codigo1&x=&date=02/01/2017" --load-cookies=cookies.txt
wget http://mywebsite.com/teste?id=codigo1&x=&date=03/01/2017" --load-cookies=cookies.txt
wget http://mywebsite.com/teste?id=codigo2&x=&date=01/01/2017" --load-cookies=cookies.txt
wget http://mywebsite.com/teste?id=codigo2&x=&date=02/01/2017" --load-cookies=cookies.txt
wget http://mywebsite.com/teste?id=codigo2&x=&date=03/01/2017" --load-cookies=cookies.txt

if the file codigos.txt contains:

codigo1
codigo2

and dates.txt contains:

01/01/2017
02/01/2017
03/01/2017

then this will work:

mywget() {
    wget "http://mywebsite.com/teste?id=$1&x=&date=$2" --load-cookies=cookies.txt;
}
export -f mywget
parallel mywget :::: codigos.txt dates.txt
