form
Sets the request body as form data and changes the HTTP method to POST.
Important: When called multiple times, parameters are accumulated instead of replaced. This allows you to compose form data from multiple sources or add parameters conditionally.
This method automatically:
Sets the HTTP method to POST
Sets Content-Type header to "application/x-www-form-urlencoded"
URL-encodes all form parameters
Accumulates parameters across multiple calls
Parameters
formBuilder
A lambda to build the form parameters using map syntax.
