Class HTTPRequest

java.lang.Object
  net.grinder.plugin.http.HTTPRequest

public class HTTPRequest
extends Object

An individual HTTP request for use in scripts.

Scripts can set default values for the URL, headers, and data. There are several overloaded methods corresponding to each HTTP method (GET, POST, ...) that allow specific values to override the defaults.

WARNING: The default values set with the various set methods, and apply to all users of the HTTPRequest. If a worker thread needs to set a thread specific value, it should either use its own HTTPRequest, or not use the defaults and pass the value as an argument to the HTTP method.

Streaming

There are variants of POST, PUT, and OPTIONS that accept an input stream, so an arbitrarily large amount of data can be sent without requiring a corresponding amount of memory. The streaming behaviour will vary depending on the version of HTTP in use and whether a Content-Length header has been supplied - please refer to the HttpOutputStream class Javadoc for full details. If you are streaming output to avoid loading complete request messages into memory, you may also want to use setReadResponseBody(boolean) to disable the reading of response bodies, and managed them yourself.

Constructor Detail

HTTPRequest

public HTTPRequest()

Creates a new HTTPRequest instance.

Method Detail

getUrl

public final String getUrl()

Gets the default URL.

Returns:

The default URL to be used for this request, or null if the default URL has not been set.

setUrl

public final void setUrl(String url)
                  throws ParseException,
                         URLException

Sets the default URL. The value given must be an absolute URL, including protocol and the server information.

See the warning above regarding thread safety. Multiple worker threads that need to set a specific URL should either not share the same HTTPRequest, or pass the URL as an argument to the call to the HTTP method.

Parameters:

url - The URL to be used for this request.

Throws:

ParseException - If the URL cannot be parsed.

URLException - If the URL is not absolute.

getHeaders

public final NVPair[] getHeaders()

Gets the default headers.

Returns:

The default headers to be used for this request.

setHeaders

public final void setHeaders(NVPair[] headers)

Sets the default headers.

See the warning above regarding thread safety. Multiple worker threads that need to set specific headers should either not share the same HTTPRequest, or pass the headers as an argument to the call to the HTTP method.

Parameters:

headers - The default headers to be used for this request.

toString

public String toString()

Returns a string representation of the object and URL headers.

Overrides:

toString in class Object

Returns:

a string representation of the object

getData

public final byte[] getData()

Gets the default data.

Returns:

The default data to be used for this request.

setData

public final void setData(byte[] data)

Sets the default data.

See the warning above regarding thread safety. Multiple worker threads that need to set specific data should either not share the same HTTPRequest, or pass the data as an argument to the call to POST, or PUT.

Parameters:

data - The default data to be used for this request.

setDataFromFile

public final byte[] setDataFromFile(String filename)
                             throws IOException

Sets the default data from a file.

See the warning above regarding thread safety. Multiple worker threads that need to set specific data should either not share the same HTTPRequest, or pass the data as an argument to the call to POST, or PUT. If the later is done, this method can still be used to read data from a file.

Parameters:

filename - Path name of data file.

Returns:

The data read from the file.

Throws:

IOException - If the file could not be read.

getFormData

public final NVPair[] getFormData()

Gets the default form data.

Returns:

The default form or query data to be used for this request.

setFormData

public final void setFormData(NVPair[] formData)

Sets the default form data.

Parameters:

formData - The default form or query data to be used for this request.

getReadResponseBody

public boolean getReadResponseBody()

Return whether or not the whole response body will be read.

Returns:

true => The response body will be read.

See Also:

setReadResponseBody(boolean)

setReadResponseBody

public void setReadResponseBody(boolean b)

Set whether or not the whole response body will be read.

If true, the response body will be read during one of the HTTP method operations (GET, PUT, ...). Otherwise, the response body will not be read. Most users will want to leave this set to its default value of true.

If set to false, the response body stream will be available for reading from the HTTPResponse.getInputStream(), and the following effects will be observed for the test statistics:

1. The time taken to read the body will not included in the recorded test time.
2. The response body length will be recorded as 0.

If desired, the caller could manually update the statistics by extending HTTPRequest and implementing processResponse(HTTPClient.HTTPResponse) as follows:

   final PluginProcessContext pluginProcessContext =
     getPluginProcessContext();

   final HTTPPluginThreadState threadState =
     (HTTPPluginThreadState)pluginProcessContext.getPluginThreadListener();

   final PluginThreadContext threadContext = threadState.getThreadContext();

   threadContext.resumeClock();
   final int bodyLength = ... // Read body from HTTPResponse.
   threadContext.pauseClock();

   final StatisticsForTest testStatistics = statistics.getForCurrentTest();
   testStatistics.addLong(
     StatisticsIndexMap.HTTP_PLUGIN_RESPONSE_LENGTH_KEY, bodyLength);

 

Parameters:

b - true => The response body will be read.
