Function url_base::set_encoded_userinfo

Set the userinfo.

Synopsis

Declared in header <boost/url/url_base.hpp>

url_base&
set_encoded_userinfo(pct_string_view s);

Description

The userinfo is set to the given string, which may contain percent-escapes. Escapes in the string are preserved, and reserved characters in the string are percent-escaped in the result. The effects on the user and password depend on the presence of a colon (':') in the string:

  • If an unescaped colon exists, the characters up to the colon become the user and the rest of the characters after the colon become the password. In this case has_password returns true. Otherwise,

  • If there is no colon, the user is set to the string. The function has_password returns false.

The interpretation of the userinfo as individual user and password components is scheme-dependent. Transmitting passwords in URLs is deprecated.

Example

assert( url( "http://example.com" ).set_encoded_userinfo( "john%20doe" ).user() == "john doe" );

Complexity

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

Exception Safety

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

BNF

userinfo      = [ [ user ] [ ':' password ] ]

user          = *( unreserved / pct-encoded / sub-delims )
password      = *( unreserved / pct-encoded / sub-delims / ":" )
