url::set_encoded

url::set_encoded_userinfo

Set the userinfo.

Synopsis

url_base&
set_encoded_userinfo(
    pct_string_view s);

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 will become the user and the rest of the characters after the colon will become the password. In this case has_password will return true. Otherwise,
If there is no colon, the user will be set to the string. The function has_password will return false.

Remarks

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.

Exceptions

Type	Thrown On
`system_error`	`s` contains an invalid percent-encoding.

Parameters

Name	Description
