Constructor Detail

HttpClient

public HttpClient()

Creates an instance of HttpClient using default parameter set.

See Also:

HttpClientParams

HttpClient

public HttpClient(HttpClientParams params)

Creates an instance of HttpClient using the given parameter set.

Parameters:

params - The parameters to use.

Since:

3.0

See Also:

HttpClientParams

HttpClient

public HttpClient(HttpClientParams params,
                  HttpConnectionManager httpConnectionManager)

Creates an instance of HttpClient with a user specified parameter set and HTTP connection manager.

Parameters:

params - The parameters to use.

httpConnectionManager - The connection manager to use.

Since:

3.0

HttpClient

public HttpClient(HttpConnectionManager httpConnectionManager)

Creates an instance of HttpClient with a user specified HTTP connection manager.

Parameters:

httpConnectionManager - The connection manager to use.

Since:

2.0

Method Detail

getState

public HttpState getState()

Returns HTTP state associated with the HttpClient.

Returns:

the shared client state

See Also:

setState(HttpState)

setState

public void setState(HttpState state)

Assigns HTTP state for the HttpClient.

Parameters:

state - the new HTTP state for the client

See Also:

getState()

setStrictMode

public void setStrictMode(boolean strictMode)

Deprecated. Use DefaultHttpParams.setParameter(String, Object) to exercise a more granular control over HTTP protocol strictness.

Defines how strictly the method follows the HTTP protocol specification (see RFC 2616 and other relevant RFCs). In the strict mode the method precisely implements the requirements of the specification, whereas in non-strict mode it attempts to mimic the exact behaviour of commonly used HTTP agents, which many HTTP servers expect.

Parameters:

strictMode - true for strict mode, false otherwise

See Also:

isStrictMode()

isStrictMode

public boolean isStrictMode()

Deprecated. Use DefaultHttpParams.getParameter(String) to exercise a more granular control over HTTP protocol strictness.

Returns the value of the strict mode flag.

Returns:

true if strict mode is enabled, false otherwise

See Also:

setStrictMode(boolean)

setTimeout

public void setTimeout(int newTimeoutInMilliseconds)

Deprecated. Use HttpConnectionParams.setSoTimeout(int), HttpConnectionManager.getParams().

Sets the socket timeout (SO_TIMEOUT) in milliseconds which is the timeout for waiting for data. A timeout value of zero is interpreted as an infinite timeout.

Parameters:

newTimeoutInMilliseconds - Timeout in milliseconds

setHttpConnectionFactoryTimeout

public void setHttpConnectionFactoryTimeout(long timeout)

Deprecated. Use HttpClientParams.setConnectionManagerTimeout(long), getParams()

Sets the timeout in milliseconds used when retrieving an HTTP connection from the HTTP connection manager.

Parameters:

timeout - the timeout in milliseconds

See Also:

HttpConnectionManager.getConnection(HostConfiguration, long)

setConnectionTimeout

public void setConnectionTimeout(int newTimeoutInMilliseconds)

Deprecated. Use HttpConnectionParams.setConnectionTimeout(int), HttpConnectionManager.getParams().

Sets the timeout until a connection is etablished. A value of zero means the timeout is not used. The default value is zero.

Parameters:

newTimeoutInMilliseconds - Timeout in milliseconds.

See Also:

HttpConnection.setConnectionTimeout(int)

executeMethod

public int executeMethod(HttpMethod method)
                  throws IOException,
                         HttpException

Executes the given HTTP method.

Parameters:

method - the HTTP method to execute.

Returns:

the method's response code

Throws:

IOException - If an I/O (transport) error occurs. Some transport exceptions can be recovered from.

HttpException - If a protocol exception occurs. Usually protocol exceptions cannot be recovered from.

public int executeMethod(HostConfiguration hostConfiguration,
                         HttpMethod method)
                  throws IOException,
                         HttpException

Executes the given HTTP method using custom host configuration.

Parameters:

hostConfiguration - The host configuration to use. If null, the host configuration returned by getHostConfiguration() will be used.

method - the HTTP method to execute.

Returns:

the method's response code

                         HttpException

Executes the given HTTP method using the given custom host configuration with the given custom HTTP state.

Parameters:

hostconfig - The host configuration to use. If null, the host configuration returned by getHostConfiguration() will be used.

method - the HTTP method to execute.

state - the HTTP state to use when executing the method. If null, the state returned by getState() will be used.

Returns:

the method's response code
