      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

      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
      res - SampleResult to read response into
      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.
