Several confusing encoding Functions

1. Baidu coding and decoding

Enter "Peng Chenggang" in Baidu and click "% C5 % ed % B3 % C9 % B8 % D5" in the URL bar after the search. How is this encoded, how to decode. the following two paragraphsCodeThese two questions can be solved:

// Baidu code

Console. writeline (system. Web. httputility. urlencode ("Peng Chenggang", system. Text. unicodeencoding. getencoding ("gb2312"). toupper ());

// Baidu Decoding

Console. writeline (system. web. httputility. urldecode ("% C5 % ed % B3 % C9 % B8 % D5", system. text. unicodeencoding. getencoding ("gb2312 ")));

2. html encoding and decoding Functions

// Html Encoding

System. Web. httputility. htmlencode (string); server. htmlencode (string)

// HTML Decoding

System. Web. httputility. htmldecode (string); server. htmldecode (string)

Decoding HTML tags. Non-HTML tags are not decoded, for example

--->

3. url encoding and decoding

// URL Encoding

System. Web. httputility. urlencode (string); server. urlencode (string );

System. Web. httputility. urlpathencode (string); server. urlpathencode (string );

Urlencode and urlpathencode are different in terms of encoding.

For example, urlencode encodes the entire URL (http://www.zzcn.net/full code)

Urlpathencode encode the content after http: // (www.zzcn.net)

// URL Decoding

System. Web. httputility. urldecode (string); server. urldecode (string );

4. UTF-8, gb2312 Conversion

UTF-8> gb2312

String content = "Peng Chenggang ";

Byte [] conby = encoding. utf8.getbytes (content );

Content = encoding. getencoding ("gb2312"). getstring (conby );

Console. writeline (content );

I will not write it on the contrary. I hope to have a better understanding of you. If you have any questions, please correct them. Thank you.
