boost::urls::url_base::set_encoded_path

Set the path.

Synopsis

Declared in <boost/url/url_base.hpp>

url_base&
set_encoded_path(pct_string_view s);

Description

This function sets the path to the string, which may contain percent‐escapes and can be empty. Escapes in the string are preserved, and reserved characters in the string are percent‐escaped in the result.

The library may adjust the final result to ensure that no other parts of the url is semantically affected.

Example

url u( "http://www.example.com" );

u.set_encoded_path( "path/to/file.txt" );

assert( u.encoded_path() == "/path/to/file.txt" );

Complexity

Linear in this‐>size() + s.size().

Exception Safety

Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.

BNF

path          = path-abempty    ; begins with "/" or is empty
              / path-absolute   ; begins with "/" but not "//"
              / path-noscheme   ; begins with a non-colon segment
              / path-rootless   ; begins with a segment
              / path-empty      ; zero characters

path-abempty  = *( "/" segment )
path-absolute = "/" [ segment-nz *( "/" segment ) ]
path-noscheme = segment-nz-nc *( "/" segment )
path-rootless = segment-nz *( "/" segment )
path-empty    = 0<pchar>
