A list of tokens in a comma separated HTTP field value.
Defined in header <boost/beast/http/rfc7230.hpp>
using opt_token_list = detail::basic_parsed_list< detail::opt_token_list_policy >;
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 begin
and end
,
or range-for to iterate each item:
for(auto const& token : token_list{"apple, pear, banana"}) std::cout << token << "\n";
