在我的项目中，有很多关于IP检查的要求。因为我们为网络设备编写了许多功能。在某些情况下，我们不需要环回IP和广播IP，在其他情况下，它是有效的。有些功能支持IPv6，有些则不支持。
所以我设计了一些基本的API：
Ext.define('Common.util.IPUtils', {
singleton: true,
isIpv4 : function(ip){},
isMulticast_v4 : function(ip){},
isBroadcast_v4 : function(ip, mask){},
isLoopback_v4 : function(ip){},
isAny_v4 : function(ip){},
isIpv6 : function(ip){},
isMulticast_v6 : function(ip){},
isBroadcast_v6 : function(ip){},
isLoopback_v6 : function(ip){},
isAny_v6 : function(ip){}
});通过这种方式，开发人员必须这样调用：
(Common.Util.IPUtil.isIpv4(ip)
&& !Common.Util.IPUtil.isLoopback_v4(ip)
&& !Common.Util.IPUtil.isBroadcast_v4(ip, mask)
&& !Common.Util.IPUtil.isMulticast_v4(ip)
&& !Common.Util.IPUtil.isAny_v4(ip))// etc
||
(Common.Util.IPUtil.isIpv6(ip)
&& !Common.Util.IPUtil.isLoopback_v6(ip)
&& !Common.Util.IPUtil.isBroadcast_v6(ip)
&& !Common.Util.IPUtil.isMulticast_v6(ip)
&& !Common.Util.IPUtil.isAny_v6(ip))// etc是否有可能为潜在的开发人员设计更优雅的API？
Ext.define('Common.util.IPUtils', {
singleton: true,
SUPPORT_V6 : 1,
MULTICASE : 0x0001,
BROADCAST : 0x0002,
LOOPBACK : 0x0004,
ANY : 0x0008,//0.0.0.0
checkIP : function(ip, mask, supportV6, excludeIPType){
if(Common.util.IPUtils.isIPv4(ip)){
if(excludeIPType&MULTICASE > 0 && Common.util.IPUtils.isMulticast_v4(ip)){
return false;
}
else if(excludeIPType&BROADCAST > 0 && Common.util.IPUtils.isBroadcast_v4(ip, mask)){
return false;
}
else if(excludeIPType&LOOPBACK > 0 && Common.util.IPUtils.isLoopback_v4(ip)){
return false;
}
else if(excludeIPType&ANY > 0 && Common.util.IPUtils.isAny_v4(ip)){
return false;
}
}
if(supportV6 == Common.util.IPUtils.SUPPORT_V6
&& Common.util.IPUtils.isIPv6(ip)){
if(excludeIPType&MULTICASE > 0 && Common.util.IPUtils.isMulticast_v6(ip)){
return false;
}
else if(excludeIPType&BROADCAST > 0 && Common.util.IPUtils.isBroadcast_v6(ip)){
return false;
}
else if(excludeIPType&LOOPBACK > 0 && Common.util.IPUtils.isLoopback_v6(ip)){
return false;
}
else if(excludeIPType&ANY > 0 && Common.util.IPUtils.isAny_v6(ip)){
return false;
}
}
return true;
}
});现在，开发人员会这样打电话：
Common.util.IPUtils.checkIP('10.180.0.1', 16, Common.util.IPUtils.SUPPORT_V6, Common.util.IPUtils.MULTICASE|Common.util.IPUtils.BROADCAST|Common.util.IPUtils.LOOPBACK|Common.util.IPUtils.ANY)我使用Extjs来做这个，这是一个JavaScript框架。有什么更好的想法来改善它吗？
没有人给我更多的建议。现在让我发表我的决议来回答我的问题。
我们可以在谷歌上搜索一些基本的IP验证器，但这不能满足我的需求。例如。 IP address utilities for node.js。因为我们是网络供应商，所以我们对IP检查有很多要求。
我用ExtJS实现了这个实用程序，但核心设计可以用许多其他语言实现。
以下是核心片段，它基于位图来组装许多原子验证函数。
