Method Detail

parseParameters

public Map<String,String> parseParameters(javax.servlet.http.HttpServletRequest request)

Description copied from interface: OAuthProviderSupport

Parse the oauth consumer paramters from an HttpServletRequest. The parameters are to be decoded per the OAuth spec.

Specified by:

parseParameters in interface OAuthProviderSupport

Parameters:

request - The servlet request.

Returns:

The parsed parameters.

parseHeaderParameters

protected Map<String,String> parseHeaderParameters(javax.servlet.http.HttpServletRequest request)

Parse the OAuth header parameters. The parameters will be oauth-decoded.

Parameters:

request - The request.

Returns:

The parsed parameters, or null if no OAuth authorization header was supplied.

getSupportedOAuthParameters

protected Set<String> getSupportedOAuthParameters()

Get the supported OAuth parameters. The default implementation supports only the OAuth core parameters.

Returns:

The OAuth core parameters.

getSignatureBaseString

public String getSignatureBaseString(javax.servlet.http.HttpServletRequest request)

Description copied from interface: OAuthProviderSupport

Get the signature base string for the specified request, per OAuth Core 1.0, 9.1

Specified by:

getSignatureBaseString in interface OAuthProviderSupport

Parameters:

request - The request.

Returns:

The signature base string.

normalizeUrl

protected String normalizeUrl(String url)

Normalize the URL for use in the signature. The OAuth spec says the URL protocol and host are to be lower-case, and the query and fragments are to be stripped.

Parameters:

url - The URL.

Returns:

The URL normalized for use in the signature.

loadSignificantParametersForSignatureBaseString

protected SortedMap<String,SortedSet<String>> loadSignificantParametersForSignatureBaseString(javax.servlet.http.HttpServletRequest request)

Loads the significant parameters (name-to-value map) that are to be used to calculate the signature base string. The parameters will be encoded, per the spec section 9.1.

Parameters:

request - The request.

Returns:

The significan parameters.

getBaseUrl

protected String getBaseUrl(javax.servlet.http.HttpServletRequest request)

The configured base URL for this OAuth provider for the given HttpServletRequest. Default implementation return getBaseUrl() + request URI.

Parameters:

request - The HttpServletRequest currently processed

Returns:

The configured base URL for this OAuth provider with respect to the supplied HttpServletRequest.

getBaseUrl

public String getBaseUrl()

The configured base URL for this OAuth provider.

Returns:

The configured base URL for this OAuth provider.

setBaseUrl

public void setBaseUrl(String baseUrl)

The configured base URL for the OAuth provider.

Parameters:

baseUrl - The configured base URL for the OAuth provider.
