How does the website block specific country ip/language visitors while allowing search engine spiders and their own access?

Environment: VPS, Centos, Ngix, Wordpress
1. To block all Chinese IP and Chinese language visitors
2. Blocking proxy access
3. The above access jumps to a specific page or displays a specific text
4. Allow search engine spiders such as Googlebot access
5. Allow yourself to access

Ask for more, forgive me not to write PHP code ...

To block all Chinese IP and Chinese-language visitors
It's not easy! At the beginning of your PHP file index.php, add a sentence

header("X-Blocked-Keyword: dongtaiwang.com")

Provides a way to block a specific country IP, DNS is not resolved.

The Incapsula free version provides shielding national functionality. Purely theoretical analysis, I do not know whether to help:

• Php:geoip-manual , PHP appears to have a geo module, you can access the IP address of the geographical analysis, if from the CN, processing off itself. (Usage introduction GEOIP use-PHP version )
• Language, you can try to check the HTTP header's desired language and dispose of the zh-* yourself.


• Agent Kung Fu Big This needless to say, but you can refer to the Wikipedia block table (

//zh.wikipedia.org/wiki/Special:%E5%B0%81%E7%A6%81%E5%88%97%E8%A1%A8?wpTarget=&wpOptions[]=userblocks&limit=500

Phone answer. JS code to determine whether the browser's language header contains "zh, CN" Content, do a jump is not good place to change an English browser can access.

var BrowserLang = navigator.language || navigator.userLanguage;if (BrowserLang.substr(0, 3) == "zh-") {    location = "http://www.baidu.com";}
