Constructor Detail

HTTPJavaImpl

protected HTTPJavaImpl(HTTPSamplerBase base)
Method Detail

setPostHeaders

protected void setPostHeaders(URLConnection conn)
                       throws IOException
Set request headers in preparation to opening a connection.

Parameters:
conn - URLConnection to set headers on
Throws:
IOException - if an I/O exception occurs

sendPostData

protected String sendPostData(URLConnection connection)
                       throws IOException
Send POST data from Entry to the open connection. This also handles sending data for PUT requests

Parameters:
connection - URLConnection where POST data should be sent
Returns:
a String show what was posted. Will not contain actual file upload content
Throws:
IOException - if an I/O exception occurs

setupConnection

protected HttpURLConnection setupConnection(URL u,
                                            String method,
                                            HTTPSampleResult res)
                                     throws IOException
Returns an HttpURLConnection fully ready to attempt connection. This means it sets the request method (GET or POST), headers, cookies, and authorization for the URL request.

The request infos are saved into the sample result if one is provided.

Parameters:
u - URL of the URL request
method - GET, POST etc
res - sample result to save request infos to
Returns:
HttpURLConnection ready for .connect
Throws:
IOException - if an I/O Exception occurs

readResponse

protected byte[] readResponse(HttpURLConnection conn,
                              SampleResult res)
                       throws IOException
Reads the response from the URL connection.

Parameters:
conn - URL from which to read response
Returns:
response content
Throws:
IOException - if an I/O exception occurs

getResponseHeaders

protected String getResponseHeaders(HttpURLConnection conn)
Gets the ResponseHeaders from the URLConnection

Parameters:
conn - connection from which the headers are read
Returns:
string containing the headers, one per line

sample

protected HTTPSampleResult sample(URL url,
                                  String method,
                                  boolean areFollowingRedirect,
                                  int frameDepth)
Samples the URL passed in and stores the result in HTTPSampleResult, following redirects and downloading page resources as appropriate.

When getting a redirect target, redirects are not followed and resources are not downloaded. The caller will take care of this.

Specified by:
sample in class HTTPAbstractImpl
Parameters:
url - URL to sample
method - HTTP method: GET, POST,...
areFollowingRedirect - whether we're getting a redirect target
frameDepth - Depth of this target in the frame structure. Used only to prevent infinite recursion.
Returns:
results of the sampling

disconnect

protected void disconnect(HttpURLConnection conn)

interrupt

public boolean interrupt()
Interrupt the current operation if possible.

Returns:
true if there was an operation to interrupt.
