params_view::find (1 of 2 overloads)

(Inherited from params_base)

Find a matching key.

Synopsis

iterator
find(
    string_view key,
    ignore_case_param ic = {}) const;

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.

Example

assert( (*url_view( "?first=John&last=Doe" ).params().find( "First", ignore_case )).value == "John" );

Effects

return this->find( this->begin(), key, ic );

Complexity

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 will be case-insensitive.
