Constructor Detail

XMLHTTPRequest

public XMLHTTPRequest()

Creates an instance.

Method Detail

getOnreadystatechange

public Object getOnreadystatechange()

Returns the event handler to be called when the readyState property changes.

Returns:

the event handler to be called when the readyState property changes

setOnreadystatechange

public void setOnreadystatechange(net.sourceforge.htmlunit.corejs.javascript.Function stateChangeHandler)

Sets the event handler to be called when the readyState property changes.

Parameters:

stateChangeHandler - the event handler to be called when the readyState property changes

getReadyState

public int getReadyState()

Returns the state of the request. The possible values are:

• 0 = unsent
• 1 = opened
• 2 = headers_received
• 3 = loading
• 4 = done

Returns:

the state of the request

getResponseText

public String getResponseText()

Returns the response entity body as a string.

Returns:

the response entity body as a string

getResponseXML

public Object getResponseXML()

Returns the parsed response entity body.

Returns:

the parsed response entity body

getStatus

public int getStatus()

Returns the HTTP status code returned by a request.

Returns:

the HTTP status code returned by a request

getStatusText

public String getStatusText()

Returns the HTTP response line status.

Returns:

the HTTP response line status

abort

public void abort()

Cancels the current HTTP request.

getAllResponseHeaders

public String getAllResponseHeaders()

Returns the values of all the HTTP headers.

Returns:

the resulting header information

getResponseHeader

public String getResponseHeader(String header)

Retrieves the value of an HTTP header from the response body.

Parameters:

header - the case-insensitive header name

Returns:

the resulting header information

open

public void open(String method,
                 Object url,
                 Object asyncParam,
                 Object user,
                 Object password)

Initializes the request and specifies the method, URL, and authentication information for the request.

Parameters:

method - the HTTP method used to open the connection, such as GET, POST, PUT, or PROPFIND; for XMLHTTP, this parameter is not case-sensitive; the verbs TRACE and TRACK are not allowed.

url - the requested URL; this can be either an absolute URL or a relative URL

asyncParam - indicator of whether the call is asynchronous; the default is true (the call returns immediately); if set to true, attach an onreadystatechange property callback so that you can tell when the send call has completed

user - the name of the user for authentication

password - the password for authentication

send

public void send(Object body)

Sends an HTTP request to the server and receives a response.

Parameters:

body - the body of the message being sent with the request.

setRequestHeader

public void setRequestHeader(String name,
                             String value)

Sets the specified header to the specified value.
The open method must be called before this method, or an error will occur.

Parameters:

name - the header name to set

value - the value of the header

get

public Object get(String name,
                  net.sourceforge.htmlunit.corejs.javascript.Scriptable start)

Gets a named property from the object. Normally HtmlUnit objects don't need to overwrite this method as properties are defined on the prototypes from the XML configuration. In some cases where "content" of object has priority compared to the properties consider using utility SimpleScriptable.getWithPreemption(String).

Specified by:

get in interface net.sourceforge.htmlunit.corejs.javascript.Scriptable

Overrides:

get in class SimpleScriptable

put

public void put(String name,
                net.sourceforge.htmlunit.corejs.javascript.Scriptable start,
                Object value)

Specified by:

put in interface net.sourceforge.htmlunit.corejs.javascript.Scriptable

Overrides:

put in class HtmlUnitScriptable
