public class Codecs

extends Object

getParameter(String, String)

retrieves the value associated with the parameter param in a given header string.

mpFormDataDecode(byte[], String)

This method decodes a multipart/form-data encoded string.

 public static final synchronized NVPair[] mpFormDataDecode(byte data[],
                                                            String cont_type) throws IOException

This method decodes a multipart/form-data encoded string. The boundary is parsed from the cont_type parameter, which must be of the form 'multipart/form-data; boundary=...'.
Any encoded files are created in the directory specified by dir using the encoded filename.
Note: Does not handle nested encodings (yet).
Example:

     NVPair[] opts = Codecs.mpFormDataDecode(resp.getData(),
                                      resp.getHeader("Content-length"),
                                      ".");
 

Assuming the data received looked something like:

 -----------------------------114975832116442893661388290519
 Content-Disposition: form-data; name="option"
                                                          
 doit
 -----------------------------114975832116442893661388290519
 Content-Disposition: form-data; name="comment"; filename="comment.txt"

 -----------------------------114975832116442893661388290519--
 

you would get one file called comment.txt in the current directory, and opts would contain two elements: {"option", "doit"} and {"comment", "comment.txt"}

Parameters:

data - the form-data to decode.

cont_type - the content type header (must contain the boundary string).

Returns:

an array of name/value pairs, one for each part; the name is the 'name' attribute given in the Content-Disposition header; the value is either the name of the file if a filename attribute was found, or the contents of the part.

Throws: IOException

If any file operation fails.

 public static final String getParameter(String param,
                                         String hdr)

retrieves the value associated with the parameter param in a given header string. This is used especially in headers like 'Content-type' and 'Content-Disposition'. Here is the syntax it expects:
";" param "=" ( token | quoted-string )

Parameters:

param - the parameter name

hdr - the header value

Returns:

the value for this parameter, or null if not found.
