set_path

Set the path.

Synopsis

url& set_path( string_view s);

Declared in file <boost/url/url.hpp> at line 465

Description

This function sets the path to the string, which may be empty. Reserved characters in the string are percent-escaped in the result.

NOTE

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

NOTE

This function does not encode '/' chars, which are unreserved for paths but reserved for path segments. If a path segment should include encoded '/'s to differentiate it from path separators, the functions set_encoded_path or segments should be used instead.

Example

url u( "http://www.example.com" ); u.set_path( "path/to/file.txt" ); assert( u.path() == "/path/to/file.txt" );

Complexity

Linear in `this->size() + s.size()`.

Exception Safety

Strong guarantee. Calls to allocate may throw.

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
