Direct Known Subclasses:

HttpRequestMessage, OAuthResponseMessage

Method Detail

toString

public String toString()

Overrides:

toString in class Object

completeParameters

protected void completeParameters()
                           throws IOException

Finish adding parameters; for example read an HTTP response body and parse parameters from it.

Throws:

IOException

getParameters

public List<Map.Entry<String,String>> getParameters()
                                             throws IOException

Throws:

IOException

addParameter

public void addParameter(String key,
                         String value)

addParameter

public void addParameter(Map.Entry<String,String> parameter)

addParameters

public void addParameters(Collection<? extends Map.Entry<String,String>> parameters)

getParameter

public String getParameter(String name)
                    throws IOException

Throws:

IOException

getConsumerKey

public String getConsumerKey()
                      throws IOException

Throws:

IOException

getToken

public String getToken()
                throws IOException

Throws:

IOException

getSignatureMethod

public String getSignatureMethod()
                          throws IOException

Throws:

IOException

getSignature

public String getSignature()
                    throws IOException

Throws:

IOException

getParameterMap

protected Map<String,String> getParameterMap()
                                      throws IOException

Throws:

IOException

getBodyType

public String getBodyType()

The MIME type of the body of this message.

Returns:

the MIME type, or null to indicate the type is unknown.

getBodyEncoding

public String getBodyEncoding()

The character encoding of the body of this message.

Returns:

the name of an encoding, or "ISO-8859-1" if no charset has been specified.

getHeader

public final String getHeader(String name)

The value of the last HTTP header with the given name. The name is case insensitive.

Returns:

the value of the last header, or null to indicate that there is no such header in this message.

getHeaders

public final List<Map.Entry<String,String>> getHeaders()

All HTTP headers. You can add headers to this list.

readBodyAsString

public final String readBodyAsString()
                              throws IOException

Read the body of the HTTP request or response and convert it to a String. This method isn't repeatable, since it consumes and closes getBodyAsStream.

Returns:

the body, or null to indicate there is no body.

Throws:

IOException

getBodyAsStream

public InputStream getBodyAsStream()
                            throws IOException

Get a stream from which to read the body of the HTTP request or response. This is designed to support efficient streaming of a large message. The caller must close the returned stream, to release the underlying resources such as the TCP connection for an HTTP response.

Returns:

a stream from which to read the body, or null to indicate there is no body.

Throws:

IOException

getDump

public Map<String,Object> getDump()
                           throws IOException

Construct a verbose description of this message and its origins.

             throws IOException

Throws:

IOException

Verify that the required parameter names are contained in the actual collection.

Throws:

OAuthProblemException - one or more parameters are absent.

IOException

addRequiredParameters

public void addRequiredParameters(OAuthAccessor accessor)
                           throws OAuthException,
                                  IOException,
                                  URISyntaxException

Add some of the parameters needed to request access to a protected resource, if they aren't already in the message.

Throws:

IOException

URISyntaxException

OAuthException

sign

public void sign(OAuthAccessor accessor)

                 OAuthException,
                 URISyntaxException

Add a signature to the message.

Throws:

URISyntaxException

IOException

OAuthException

getAuthorizationHeader

public String getAuthorizationHeader(String realm)
                              throws IOException
