地址在本地计算机上无效[仅在Windows 8上]（电脑上显示该地址无效）

我想检查请求url的状态码但获取代码

java.net.ConnectException: connect: Address is invalid on local machine or port is not valid on remote machine

这是我的代码

public static boolean linkExists(String URLName){        URLName = "http://www.google.com";        try {          HttpURLConnection.setFollowRedirects(false);          HttpURLConnection con =             (HttpURLConnection) new URL(URLName).openConnection();          con.connect();          System.out.println(con.getResponseCode());          return (con.getResponseCode() == HttpURLConnection.HTTP_OK);        }        catch (Exception e) {                      return false;        }  }

答案1

我认为，此问题是由Java尝试使用IPV6地址引起的，原因是您的操作系统不支持IPV6地址，或者您的操作系统没有正确设置IPV6地址来处理它。

您可以强制Java使用具有以下属性的IPV4地址：

-Djava.net.preferIPv4Stack = true

**DOCUMENT SIMILARITY** 哪种算法在本地计算机上计算是合理的？

-Ddatastore.backing_store="/path/to/datastore/file/location/local_db.bin"

Host Server_A
    IdentityFile ~/.ssh/server_A

Host Server_B
    IdentityFile ~/.ssh/server_B

Host Server_C
    IdentityFile ~/.ssh/server_C

$ip = '1337.1337.1337.1337';

$ip = $_SERVER['REMOTE_ADDR']

//$ip = '1337.1337.1337.1337';
$ip = $_SERVER['REMOTE_ADDR']

$ips = Array('192.168.1.220','120.843.592.86','256.865.463.563');
$ip = $ips[rand(1,count($ips)-1)];
