Method Detail

parse

public static List<NameValuePair> parse(URI uri,
                                        String encoding)

Returns a list of NameValuePairs as built from the URI's query portion. For example, a URI of http://example.org/path/to/file?a=1&b=2&c=3 would return a list of three NameValuePairs, one for a=1, one for b=2, and one for c=3.

This is typically useful while parsing an HTTP PUT.

Parameters:

uri - uri to parse

encoding - encoding to use while parsing the query

parse

public static List<NameValuePair> parse(HttpEntity entity)
                                 throws IOException

Returns a list of NameValuePairs as parsed from an HttpEntity. The encoding is taken from the entity's Content-Encoding header.

This is typically used while parsing an HTTP POST.

Parameters:

entity - The entity to parse

Throws:

IOException - If there was an exception getting the entity's data.

isEncoded

public static boolean isEncoded(HttpEntity entity)

Returns true if the entity's Content-Type header is application/x-www-form-urlencoded.

parse

public static void parse(List<NameValuePair> parameters,
                         Scanner scanner,
                         String encoding)

Adds all parameters within the Scanner to the list of parameters, as encoded by encoding. For example, a scanner containing the string a=1&b=2&c=3 would add the NameValuePairs a=1, b=2, and c=3 to the list of parameters.

Parameters:

parameters - List to add parameters to.

scanner - Input that contains the parameters to parse.

encoding - Encoding to use when decoding the parameters.

format

public static String format(List<? extends NameValuePair> parameters,
                            String encoding)

Returns a String that is suitable for use as an application/x-www-form-urlencoded list of parameters in an HTTP PUT or HTTP POST.

Parameters:

parameters - The parameters to include.

encoding - The encoding to use.
