The destination OutputRange where the resulting string must be written to.
An iterable key-value map iterable with foreach(string key, string value; map).
A valid form separator, common values are '&' or ';'
The following example demonstrates the use of formEncode with a json map, the ordering of keys will be preserved in Bson and DictionaryList objects only.
import std.array : Appender; string[string] map; map["numbers"] = "123456789"; map["spaces"] = "1 2 3 4 a b c d"; Appender!string app; app.formEncode(map); assert(app.data == "spaces=1+2+3+4+a+b+c+d&numbers=123456789" || app.data == "numbers=123456789&spaces=1+2+3+4+a+b+c+d");
Encodes a Key-Value map into a form URL encoded string.
Writes to the OutputRange an application/x-www-form-urlencoded MIME formatted string, ie. all spaces ' ' are replaced by the '+' character
