boost::urls::params_base::find

Find a matching key

Synopsis

iterator
find(
    core::string_view key,
    ignore_case_param ic = = {}) const noexcept;
iterator
find(
    iterator from,
    core::string_view key,
    ignore_case_param ic = = {}) const noexcept;

Description

This function examines the parameters in the container to find a match for the specified key. The comparison is performed as if all escaped characters were decoded first.

The search starts from the first param and proceeds forward until either the key is found or the end of the range is reached, in which case end() is returned.

assert( (*url_view( "?first=John&last=Doe" ).params().find( "First", ignore_case )).value == "John" );
return this->find( this->begin(), key, ic );

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

Return Value

an iterator to the param

Parameters

Name Description

key

The key to match. By default, a case-sensitive comparison is used.

ic

An optional parameter. If the value ignore_case is passed here, the comparison is case-insensitive.

from

The position to begin the search from. This can be end().
