network_home_url ( $path = '', $scheme = null )
检索当前网络的主页URL。
返回带有适当协议的主页URL,’https’是_ssl(),否则是’http’。如果`$scheme`是’http’或’https’,`is_ssl()’将被重写。
function network_home_url( $path = '', $scheme = null ) { if ( ! is_multisite() ) { return home_url( $path, $scheme ); } $current_network = get_network(); $orig_scheme = $scheme; if ( ! in_array( $scheme, array( 'http', 'https', 'relative' ), true ) ) { $scheme = is_ssl() ? 'https' : 'http'; } if ( 'relative' === $scheme ) { $url = $current_network->path; } else { $url = set_url_scheme( 'http://' . $current_network->domain . $current_network->path, $scheme ); } if ( $path && is_string( $path ) ) { $url .= ltrim( $path, '/' ); } /** * Filters the network home URL. * * @since 3.0.0 * * @param string $url The complete network home URL including scheme and path. * @param string $path Path relative to the network home URL.
