Return the userinfo.

Synopsis

template<
    class StringToken = string_token::return_string>
StringToken::result_type
userinfo(
    StringToken&& token = {}) const;

Description

If present, this function returns a string representing the userinfo (which may be empty). Otherwise it returns an empty string. Any percent-escapes in the string are decoded first.

Remarks

This function uses the string token return type customization. Depending on the token passed, the return type and behavior of the function can be different. See string_token::return_string for more information.

Example

assert( url_view( "http://jane%2Ddoe:pass@example.com" ).userinfo() == "jane-doe:pass" );

Complexity

Linear in this->userinfo().size().

Exception Safety

Calls to allocate may throw.

Return Value

When called with no arguments, a value of type std::string is returned. Otherwise, the return type and meaning depends on the string token passed to the function.

BNF

userinfo    = user [ ":" [ password ] ]

authority   = [ userinfo "@" ] host [ ":" port ]
