比如我现在有一个这样的字符串%0aWhois%20Server%20Version%201%2e0%0a%0aDomain%20names%20can%20now%20be%20registered%20with%20many%20different%20competing%20registrars%2e%20%0aGo%20to%20http%3a%2f%2fregistrar%2everisign%2dgrs%2ecom%2fwhois%2f%20for%20detailed%20information%2e%0a%0a%20%20%20Domain%20Name%3a%20IZB%2eCC%0a%20%20%20Registrar%3a%201%20API%20GMBH%0a%20%20%20Whois%20Server%3a%20whois%2e1api%2enet%0a%20%20%20Referral%20URL%3a%20http%3a%2f%2fwww%2e1api%2enet%0a%20%20%20Name%20Server%3a%20FREE01%2eEDITDNS%2eNET%0a%20%20%20Name%20Server%3a%20FREE02%2eEDITDNS%2eNET%0a%20%20%20Status%3a%20ACTIVE%0a%20%20%20Updated%20Date%3a%2013%2dmay%2d2010%0a%20%20%20Creation%20Date%3a%2002%2doct%2d2009%0a%20%20%20Expiration%20Date%3a%2002%2doct%2d2010%0a%0a%0a%3e%3e%3e%20Last%20update%20of%20whois%20database%3a%20Wed%2c%202%20Jun%202010%2008%3a02%3a29%20EDT%20%3c%3c%3c%0a%0aNOTICE%3a%20The%20expiration%20date%20displayed%20in%20this%20record%20is%20the%20date%20the%20%0aregistrar%27s%20sponsorship%20of%20the%20domain%20name%20registration%20in%20the%20registry%20is%20%0acurrently%20set%20to%20expire%2e%20This%20date%20does%20not%20necessarily%20reflect%20the%20%0aexpiration%20date%20of%20the%20domain%20name%20registrant%27s%20agreement%20with%20the%20%0asponsoring%20registrar%2e%20%20Users%20may%20consult%20the%20sponsoring%20registrar%27s%20%0aWhois%20database%20to%20view%20the%20registrar%27s%20reported%20date%20of%20expiration%20%0afor%20this%20registration%2e%0a%0aTERMS%20OF%20USE%3a%20You%20are%20not%20authorized%20to%20access%20or%20query我用php的URLDecode函数解密，成这样了：Whois Server Version 1.0 Domain names can now be registered with many different competing registrars. Go to http://registrar.verisign-grs.com/whois/ for detailed information. Domain Name: IZB.CC Registrar: 1 API GMBH Whois Server: whois.1api.net Referral URL: http://www.1api.net Name Server: FREE01.EDITDNS.NET Name Server: FREE02.EDITDNS.NET Status: ACTIVE Updated Date: 13-may-2010 Creation Date: 02-oct-2009 Expiration Date: 02-oct-2010 >>> Last update of whois database: Wed, 2 Jun 2010 08:02:29 EDT <<< NOTICE: The expiration date displayed in this record is the date the registrar's sponsorship of the domain name registration in the registry is currently set to expire. This date does not necessarily reflect the expiration date of the domain name registrant's agreement with the sponsoring registrar. Users may consult the sponsoring registrar's Whois database to view the registrar's reported date of expiration for this registration.但是我在这里解密http://tool.chinaz.com/Tools/Encode.aspx却能得到这样的结果Whois Server Version 1.0Domain names can now be registered with many different competing registrars.
