Find a matching key

Synopsis

Declared in header </boost/url/params_encoded_base.hpp#L356[boost/url/params_encoded_base.hpp,window=blank_]>

iterator
find(
    pct_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, which may contain percent escapes. 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" ).encoded_params().find( "First", ignore_case )->value == "John" );

Effects

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

Complexity

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

Exception Safety

Exceptions thrown on invalid input.
