Construct a list. |
This container allows iteration of a list of items in a header field value. The input is a comma separated list of tokens. If a parsing error is encountered while iterating the string, the behavior of the container will be as if a string containing only characters up to but excluding the first invalid character was used to construct the list.
token-list = *( "," OWS ) token *( OWS "," [ OWS token ] )
To use this class, construct with the string to be parsed and then use http::token_list::begin
and http::token_list::end
, or range-for to iterate each
item:
for(auto const& token : token_list{"apple, pear, banana"}) std::cout << token << "\n";
