Get request with one-item array param, will send the value inside instead the the array about gaxios HOT 1 CLOSED

Hi @choyzer, thanks for submitting this. For our use case, I think this is working as intended. We use the paramsSerializer method from the Node core library, which parses arrays in this way:

querystring.stringify({ foo: 'bar', baz: ['qux', 'quux'], corge: '' });
// Returns 'foo=bar&baz=qux&baz=quux&corge='

So it actually always returns single elements without an array. Testing this locally, this request:

   const res = await request({
      url,
      params: {querystring: ['a', 'b']},
    });

returns:

https://example.com/?querystring=a&querystring=b

and

   const res = await request({
      url,
      params: {querystring: ['a', 'b']},
    });

returns

https://example.com/?querystring=a

For some more insight, in our cases, an array is a repeated field so when query string is encoded, it's literally repeated. If you really wanted to include the brackets, you could JSON.stringify the parameter and pass it as a string.

Hope this helps, feel free to reopen if you feel this still isn't resolved!
