Send array with GET Request

Question

I am making a get request form Javascript to Python. And I am trying to pass a 2D array so something like

[["one", "two"],["foo", "bar"]]

And here is what I am currently trying but it is not working.

So in my javascript I have an array that look similar to the one above, and then pass it like this

var xmlHttp = new XMLHttpRequest();
xmlHttp.open( "GET", "http://192.67.64.41/cgi-bin/hi.py?array=" + myArray, false );
xmlHttp.send( null );

And then in python I get it like this

import cgi
form = cgi.FieldStorage()
array = form.getvalue("array")

But it doesn't come out right, in python then if I were to do

print array[0]
#I get -> "o"
print array[1]
#I get -> "n"
print array[2]
#I get -> "e"

and so on, but if I what I want is

print array[0]
#output -> ["one", "two"]

How can I accomplish this?

Thanks

Solution

You can't simply pass an array as a query parameter. You will need to iterate over the array and add it so the URL string such as ?array[]=one&array[]=two

Here is a basic jsfiddle as an example

var a=['one', 'two'];
var url = 'www.google.com';

for (var i=0; i<a.length; ++i) {
    if (url.indexOf('?') === -1) {
        url = url + '?array[]=' + a[i];  
    }else {
        url = url + '&array[]=' + a[i];
    }
}

console.log(url);
