operator params_view

Conversion

Description

Objects of this type are used to interpret the query parameters as a bidirectional view of key/value pairs. The view does not retain ownership of the elements and instead references the original character buffer. The caller is responsible for ensuring that the lifetime of the buffer extends until it is no longer referenced.

Example

url_view u( "?first=John&last=Doe" );

params_encoded_view p = u.encoded_params();

Strings produced when elements are returned have type param_pct_view and represent encoded strings. Strings passed to member functions may contain percent escapes, and throw exceptions on invalid inputs.

Iterator Invalidation

Changes to the underlying character buffer can invalidate iterators which reference it.
