Method Details

parse

@Deprecated
public static List<NameValuePair> parse(URI uri,
 String charsetName)

Deprecated.

4.5 Use parse(URI, Charset)

parse

public static List<NameValuePair> parse(URI uri,
 Charset charset)

Returns a list of NameValuePairs URI query parameters. By convention, '&' and ';' are accepted as parameter separators.

Parameters:

uri - input URI.

charset - parameter charset.

Returns:

list of query parameters.

Since:

4.5

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

Returns:

a list of NameValuePair as built from the URI's query portion.

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

@Deprecated
public static void parse(List<NameValuePair> parameters,
 Scanner scanner,
 String charset)

Deprecated.

(4.4) use parse(String, java.nio.charset.Charset)

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. By convention, '&' and ';' are accepted as parameter separators.

Parameters:

parameters - List to add parameters to.

scanner - Input that contains the parameters to parse.

charset - Encoding to use when decoding the parameters.

parse

@Deprecated
public static void parse(List<NameValuePair> parameters,
 Scanner scanner,
 String parameterSepartorPattern,
 String charset)

Deprecated.

(4.4) use parse(org.apache.http.util.CharArrayBuffer, java.nio.charset.Charset, char...)

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.

parameterSepartorPattern - The Pattern string for parameter separators, by convention "[&;]"

charset - Encoding to use when decoding the parameters.

parse

public static List<NameValuePair> parse(String s,
 Charset charset)
