HomeBackend DevelopmentPHP Tutorial获取本机外网ip地址的老问题

遇到了跟之前的一篇帖子一样的问题
各种方法获取本地外网ip时,各种返回::1。
大部分是说因为ipv6的原因。但关掉后,电脑彻底无法上网了。
不知道现在有没有除了接口以外的解决办法。


回复讨论(解决方案)

ipv6 的 ::1,就是 ipv4 的 127.0.0.1
不知道你是怎么做的

你获取的是ipv6?

ipv6 的 ::1,就是 ipv4 的 127.0.0.1

度娘“本机外网ip地址 php”就会出现n中解决办法,下面截取一例:
function get_onlineip() { $onlineip = ''; if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) { $onlineip = getenv('HTTP_CLIENT_IP'); } elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) { $onlineip = getenv('HTTP_X_FORWARDED_FOR'); } elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) { $onlineip = getenv('REMOTE_ADDR'); } elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) { $onlineip = $_SERVER['REMOTE_ADDR']; } return $onlineip; } var_dump(get_onlineip());

本机是武汉的,本意是想获得本机IP: 27.19.xxx.xxx 湖北省武汉市 电信    这种ip地址。$_SERVER我也不是很懂。在localhost上运行的,所以出现::1是因为ipv6,还是localhost,我也不是很清楚。可以不深究这个问题,因为只想从php里获得 27.19.xxx.xxx这种ip地址

麻烦了

你在本机访问就只能得到 ::1 或 127.0.0.1 或 你机器的 ip
外网的 ip 要从外网访问才能得到

如果是Linux系统用php执行“curl ifconfig.me”可以得到外网IP

嗯,这个别人也跟我讲过。
我奇怪的是,度娘“本机外网ip地址”,就会给我27.19.xxx.xxx的ip地址。我也没有一个页面可以给他访问来获取我外网的ip地址啊,所以也不能在cmd中用ipconfig。
那度娘是怎么得到“27.19.xxx.xxx”的?

如果是Linux系统用php执行“curl ifconfig.me”可以得到外网IP


谢啦~~目前用的wamp环境。

你访问他时,用的不就是外网 ip 吗?

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners.
