Pascal (Lazarus/Delphi)
Add a Query Parameter from a StringBuilder
See more REST Examples
Demonstrates Rest.AddQueryParamSb, which adds or replaces a query parameter whose value is read from a StringBuilder. The 1st argument is the name and the 2nd is the StringBuilder.
Background. This variant is convenient when the parameter value has already been assembled in a StringBuilder, avoiding an extra conversion to a plain string.
