public class HttpUtil
extends java.lang.Object
Provides utility functions useful in HTTP communications
static String | encodeBasicAuthentication(String pUser, String pPassword, String pEncoding) - Creates the Base64 encoded credentials for HTTP Basic Authentication.
|
static String | getNonIdentityTransferEncoding(String pHeaderValue) - Returns, whether the HTTP header value
pHeaderValue
indicates, that another encoding than "identity" is used.
|
static boolean | isUsingGzipEncoding(Enumeration pValues) - Returns, whether the HTTP header values in
pValues
indicate, that GZIP encoding is used or may be used.
|
static boolean | isUsingGzipEncoding(String pHeaderValue) - Returns, whether the HTTP header value
pHeaderValue
indicates, that GZIP encoding is used or may be used.
|
static void | parseAuthorization(XmlRpcHttpRequestConfigImpl pConfig, String pLine) - Parses an "Authorization" header and adds the username and password
to
pConfig .
|
static String | readLine(InputStream pIn, byte[] pBuffer) - Reads a header line from the input stream
pIn
and converts it into a string.

encodeBasicAuthentication
public static String encodeBasicAuthentication(String pUser,
String pPassword,
String pEncoding)
throws UnsupportedEncodingException
Creates the Base64 encoded credentials for HTTP Basic Authentication.
pUser
- User name, or null, if no Basic Authentication is being used.pPassword
- Users password, or null, if no Basic Authentication is being used.pEncoding
- Encoding being used for conversion of the credential string into a byte array.
- Base64 encoded credentials, for use in the HTTP header
getNonIdentityTransferEncoding
public static String getNonIdentityTransferEncoding(String pHeaderValue)
Returns, whether the HTTP header value pHeaderValue
indicates, that another encoding than "identity" is used.
This is typically the value of "Transfer-Encoding", or "TE".
- Null, if the transfer encoding in use is "identity".
Otherwise, another transfer encoding.
isUsingGzipEncoding
public static boolean isUsingGzipEncoding(Enumeration pValues)
Returns, whether the HTTP header values in pValues
indicate, that GZIP encoding is used or may be used.
pValues
- The HTTP header values being parsed. These are typically
the values of "Content-Encoding", or "Accept-Encoding".
- True, if the header values suggests that GZIP encoding is or may
be used.
isUsingGzipEncoding
public static boolean isUsingGzipEncoding(String pHeaderValue)
Returns, whether the HTTP header value pHeaderValue
indicates, that GZIP encoding is used or may be used.
pHeaderValue
- The HTTP header value being parsed. This is typically
the value of "Content-Encoding", or "Accept-Encoding".
- True, if the header value suggests that GZIP encoding is or may
be used.
parseAuthorization
public static void parseAuthorization(XmlRpcHttpRequestConfigImpl pConfig,
String pLine)
Parses an "Authorization" header and adds the username and password
to pConfig
.
pConfig
- The request configuration being created.pLine
- The header being parsed, including the "basic" part.
readLine
public static String readLine(InputStream pIn,
byte[] pBuffer)
throws IOException
Reads a header line from the input stream pIn
and converts it into a string.
pIn
- The input stream being read.pBuffer
- A buffer being used for temporary storage.
The buffers length is a limit of the header lines length.
- Next header line or null, if no more header lines
are available.
