xtd::string xtd::uri::authority

(

)

const

Gets the Domain Name System (DNS) host name or IP address and the port number for a server.

Returns

The authority component of the URI represented by this instance.

Exceptions

xtd::invalid_operation_exception

This instance represents a relative URI, and this property is valid only for absolute URIs.

Examples

The following example writes the host name (www.contoso.com) and port number (8080) of the server to the console.

auto base_uri = uri("http://www.contoso.com:8080/");
auto my_uri = uri(base_uri,"shownew.htm?date=today");
 
console::write_line(my_uri.authority());

Remarks

The xtd::uri::authority property is typically a server DNS host name or IP address. This property might include the service port number if it differs from the default port for the URI. If the xtd::uri::authority component contains reserved characters, these are escaped in the string value returned by this property.
