类 UrlCoder

java.lang.Object

net.dongliu.commons.http.UrlCoder

public class UrlCoder
extends Object

Util methods for encode / decode uri.

Encode diffs between url path segment, path parameter, and query part, follow the RFC3986:

For HTTP URLs, a space in a path fragment part has to be encoded to "%20" (not, absolutely not "+"), while the "+" character in the path fragment part can be left unencoded. Now in the query part, spaces may be encoded to either "+" (just for backwards compatibility) or "%20" while the "+" character has to be escaped to "%2B".

"?" is allowed unescaped anywhere within a query part, "/" is allowed unescaped anywhere within a query part, "=" is allowed unescaped anywhere within a path parameter or query parameter value, and within a path segment, ":@-._~!$&'()*+,;=" are allowed unescaped anywhere within a path segment part, "/?:@-._~!$&'()*+,;=" are allowed unescaped anywhere within a fragment part.

 For "https://bob:bobby@www.lunatech.com:8080/file;p=1?q=2#third", we can extract the following information:

     Scheme     https
     User       bob
     Password   bobby
     Host address       www.lunatech.com
     Port       8080
     Path       /file
     Path parameters    p=1
     Query parameters   q=2
     Fragment   third
 

java.net.URLEncoder is used to convert a String to the application/x-www-form-urlencoded MIME format, which is not suitable for encode urls
