RequestUtil
public RequestUtil()
encodeCookie
public static java.lang.String encodeCookie(javax.servlet.http.Cookie cookie)
- Encode a cookie as per RFC 2109. The resulting string can be used
as the value for a
Set-Cookie
header.
- Parameters:
cookie
- The cookie to encode.- Returns:
- A string following RFC 2109.
parseCharacterEncoding
public static java.lang.String parseCharacterEncoding(java.lang.String contentType)
- Parse the character encoding from the specified content type header.
If the content type is null, or there is no explicit character encoding,
null
is returned.
- Parameters:
contentType
- a content type header
parseCookieHeader
public static javax.servlet.http.Cookie[] parseCookieHeader(java.lang.String header)
- Parse a cookie header into an array of cookies according to RFC 2109.
- Parameters:
header
- Value of an HTTP "Cookie" header
parseParameters
public static void parseParameters(java.util.Map map,
java.lang.String data)
- Append request parameters from the specified String to the specified
Map. It is presumed that the specified Map is not accessed from any
other thread, so no synchronization is performed.
IMPLEMENTATION NOTE: URL decoding is performed
individually on the parsed name and value elements, rather than on
the entire query string ahead of time, to properly deal with the case
where the name or value includes an encoded "=" or "&" character
that would otherwise be interpreted as a delimiter.
- Parameters:
map
- Map that accumulates the resulting parametersdata
- Input string containing request parameters- Throws:
java.lang.IllegalArgumentException
- if the data is malformed
URLDecode
public static java.lang.String URLDecode(java.lang.String str)
throws java.lang.IllegalArgumentException
- Decode and return the specified URL-encoded String.
- Parameters:
str
- The url-encoded string- Throws:
java.lang.IllegalArgumentException
- if a '%' character is not followed
by a valid 2-digit hexadecimal number
