getAttribute

public Object getAttribute(String name)

Description copied from interface: javax.servlet.ServletRequest

Returns the value of the named attribute as an Object, or null if no attribute of the given name exists.

Attributes can be set two ways. The servlet container may set attributes to make available custom information about a request. For example, for requests made using HTTPS, the attribute javax.servlet.request.X509Certificate can be used to retrieve information on the certificate of the client. Attributes can also be set programatically using ServletRequest.setAttribute(java.lang.String, java.lang.Object). This allows information to be embedded into a request before a RequestDispatcher call.

Attribute names should follow the same conventions as package names. This specification reserves names matching java.*, javax.*, and sun.*.

Attribute names should follow the same conventions as package names. Names beginning with java.*, javax.*, and com.sun.*, are reserved for use by Sun Microsystems.

Specified by:

removeAttribute in interface ServletRequest

Parameters:

name - a String specifying the name of the attribute to remove

setAttribute

public void setAttribute(String name,
                         Object value)

getParameter

public String getParameter(String name)

Description copied from interface: javax.servlet.ServletRequest

Returns the value of a request parameter as a String, or null if the parameter does not exist. Request parameters are extra information sent with the request. For HTTP servlets, parameters are contained in the query string or posted form data.

You should only use this method when you are sure the parameter has only one value. If the parameter might have more than one value, use ServletRequest.getParameterValues(java.lang.String).

If you use this method with a multivalued parameter, the value returned is equal to the first value in the array returned by getParameterValues.

If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via ServletRequest.getInputStream() or ServletRequest.getReader() can interfere with the execution of this method.

Specified by:

getParameter in interface ServletRequest

Parameters:

name - a String specifying the name of the parameter

Returns:

a String representing the single value of the parameter

See Also:

ServletRequest.getParameterValues(java.lang.String)

getParameterMap

public Map<String,String[]> getParameterMap()

Description copied from interface: javax.servlet.ServletRequest

Returns a java.util.Map of the parameters of this request. Request parameters are extra information sent with the request. For HTTP servlets, parameters are contained in the query string or posted form data.

Specified by:

getParameterMap in interface ServletRequest

Returns:

an immutable java.util.Map containing parameter names as keys and parameter values as map values. The keys in the parameter map are of type String. The values in the parameter map are of type String array.

getParameterNames

public Enumeration<String> getParameterNames()

Description copied from interface: javax.servlet.ServletRequest

Returns:

an Enumeration of String objects, each String containing the name of a request parameter; or an empty Enumeration if the request has no parameters

getParameterValues

public String[] getParameterValues(String name)

Description copied from interface: javax.servlet.ServletRequest

Returns an array of String objects containing all of the values the given request parameter has, or null if the parameter does not exist.

If the parameter has a single value, the array has a length of 1.

Specified by:

getParameterValues in interface ServletRequest

Parameters:

name - a String containing the name of the parameter whose value is requested

Returns:

an array of String objects containing the parameter's values

See Also:

ServletRequest.getParameter(java.lang.String)

getRequestDispatcher

public RequestDispatcher getRequestDispatcher(String path)

Description copied from interface: javax.servlet.ServletRequest

Returns a RequestDispatcher object that acts as a wrapper for the resource located at the given path. A RequestDispatcher object can be used to forward a request to the resource or to include the resource in a response. The resource can be dynamic or static.

The pathname specified may be relative, although it cannot extend outside the current servlet context. If the path begins with a "/" it is interpreted as relative to the current context root. This method returns null if the servlet container cannot return a RequestDispatcher.

The difference between this method and ServletContext.getRequestDispatcher(java.lang.String) is that this method can take a relative path.

Specified by:

getRequestDispatcher in interface ServletRequest

Parameters:

path - a String specifying the pathname to the resource. If it is relative, it must be relative against the current servlet.

Returns:

a RequestDispatcher object that acts as a wrapper for the resource at the specified path, or null if the servlet container cannot return a RequestDispatcher

See Also:

RequestDispatcher, ServletContext.getRequestDispatcher(java.lang.String)

getAuthType

public String getAuthType()

Description copied from interface: javax.servlet.http.HttpServletRequest

Returns the name of the authentication scheme used to protect the servlet. All servlet containers support basic, form and client certificate authentication, and may additionally support digest authentication. If the servlet is not authenticated null is returned.

Same as the value of the CGI variable AUTH_TYPE.

Specified by:

getAuthType in interface HttpServletRequest

Returns:

one of the static members BASIC_AUTH, FORM_AUTH, CLIENT_CERT_AUTH, DIGEST_AUTH (suitable for == comparison) or the container-specific string indicating the authentication scheme, or null if the request was not authenticated.

getCookies

public Cookie[] getCookies()

Description copied from interface: javax.servlet.http.HttpServletRequest

Returns an array containing all of the Cookie objects the client sent with this request. This method returns null if no cookies were sent.

Specified by:

The date is returned as the number of milliseconds since January 1, 1970 GMT. The header name is case insensitive.

If the request did not have a header of the specified name, this method returns -1. If the header can't be converted to a date, the method throws an IllegalArgumentException.

Specified by:

getDateHeader in interface HttpServletRequest

Parameters:

name - a String specifying the name of the header

Returns:

a long value representing the date specified in the header expressed as the number of milliseconds since January 1, 1970 GMT, or -1 if the named header was not included with the request

an Enumeration containing the values of the requested header. If the request does not have any headers of that name return an empty enumeration. If the container does not allow access to header information, return null

getHeaderNames

public Enumeration<String> getHeaderNames()

Description copied from interface: javax.servlet.http.HttpServletRequest

Returns an enumeration of all the header names this request contains. If the request has no headers, this method returns an empty enumeration.

Some servlet containers do not allow servlets to access headers using this method, in which case this method returns null

Specified by:

Returns:

an enumeration of all the header names sent with this request; if the request has no headers, an empty enumeration; if the servlet container does not allow servlets to use this method, null

getIntHeader

public int getIntHeader(String name)

Description copied from interface: javax.servlet.http.HttpServletRequest

Returns the value of the specified request header as an int. If the request does not have a header of the specified name, this method returns -1. If the header cannot be converted to an integer, this method throws a NumberFormatException.

The header name is case insensitive.

Specified by:

Parameters:

name - a String specifying the name of a request header

Returns:

an integer expressing the value of the request header or -1 if the request doesn't have a header of this name

a String specifying the name of the method with which this request was made

getPathTranslated

public String getPathTranslated()

Description copied from interface: javax.servlet.http.HttpServletRequest

Returns any extra path information after the servlet name but before the query string, and translates it to a real path. Same as the value of the CGI variable PATH_TRANSLATED.

If the URL does not have any extra path information, this method returns null or the servlet container cannot translate the virtual path to a real path for any reason (such as when the web application is executed from an archive). The web container does not decode this string.

Specified by:

getPathTranslated in interface HttpServletRequest

Returns:

a String specifying the real path, or null if the URL does not have any extra path information

getRemoteUser

public String getRemoteUser()

Description copied from interface: javax.servlet.http.HttpServletRequest

Returns the login of the user making this request, if the user has been authenticated, or null if the user has not been authenticated. Whether the user name is sent with each subsequent request depends on the browser and type of authentication. Same as the value of the CGI variable REMOTE_USER.

Specified by:

getRequestedSessionId in interface HttpServletRequest

Returns:

a String specifying the session ID, or null if the request did not specify a session ID

See Also:

HttpServletRequest.isRequestedSessionIdValid()

getRequestURI

public String getRequestURI()

Description copied from interface: javax.servlet.http.HttpServletRequest

Returns the part of this request's URL from the protocol name up to the query string in the first line of the HTTP request. The web container does not decode this String. For example:

First line of HTTP request	Returned Value
POST /some/path.html HTTP/1.1		/some/path.html
GET http://foo.bar/a.html HTTP/1.0		/a.html
HEAD /xyz?a=b HTTP/1.1		/xyz

To reconstruct an URL with a scheme and host, use HttpUtils.getRequestURL(javax.servlet.http.HttpServletRequest).

Specified by:

getRequestURI in interface HttpServletRequest

Returns:

a String containing the part of the URL from the protocol name up to the query string

See Also:

HttpUtils.getRequestURL(javax.servlet.http.HttpServletRequest)

setDecodedRequestURI

public void setDecodedRequestURI(String uri)

getRequestURL

public StringBuffer getRequestURL()

Description copied from interface: javax.servlet.http.HttpServletRequest

Reconstructs the URL the client used to make the request. The returned URL contains a protocol, server name, port number, and server path, but it does not include query string parameters.

Because this method returns a StringBuffer, not a string, you can modify the URL easily, for example, to append query parameters.

This method is useful for creating redirect messages and for reporting errors.

Specified by:

getRequestURL in interface HttpServletRequest

Returns:

a StringBuffer object containing the reconstructed URL

getSession

public HttpSession getSession()

Description copied from interface: javax.servlet.http.HttpServletRequest

Returns the current session associated with this request, or if the request does not have a session, creates one.

getSession

public HttpSession getSession(boolean create)

Description copied from interface: javax.servlet.http.HttpServletRequest

Returns the current HttpSession associated with this request or, if there is no current session and create is true, returns a new session.

If create is false and the request has no valid HttpSession, this method returns null.

Specified by:

getSession in interface HttpServletRequest

Parameters:

create - true to create a new session for this request if necessary; false to return null if there's no current session

Returns:

the HttpSession associated with this request or null if create is false and the request has no valid session
