Extracting Error Snapshots
The following programming example extracts all received content data of error snapshots taken (malformed web pages), and stores them in files so they can be displayed later in the web browser:
Code
import java.io.FileOutputStream;
import dfischer.utils.PerformanceData;
import dfischer.utils.PerformanceDataRecord;
import dfischer.utils.PerformanceDataRecordFailureInfo;
import dfischer.utils.HttpTestURL;
/**
* Writes the response content of all error snapshots to files if they contain ASCII (HTML,XML) data.
* Program Argument: name of the result file (*.prxres).
*/
public class ExtractErrors
{
public static void main(String[] args)
{
try
{
// read result file from disk
PerformanceData performanceData = new PerformanceData();
performanceData.readObjectFromFile(args[0]);
// loop over all measured url calls and page breaks
PerformanceDataRecord[] performanceDataRecord = performanceData.getPerformanceDataRecord();
for (int x = 0; x < performanceDataRecord.length; x++)
{
switch (performanceDataRecord[x].getDataType())
{
case PerformanceDataRecord.TYPE_PERFORMANCE_DATA:
// loop over all error snapshots per url call
PerformanceDataRecordFailureInfo[] failureInfo = performanceDataRecord[x].getFailureInfo();
for (int y = 0; y < failureInfo.length; y++)
{
// get data of failed url call
HttpTestURL testURL = performanceDataRecord[x].getFailedUrl(failureInfo[y]);
if (testURL != null)
{
// now we have access to all frozen url data
String fileStartName = "url_" + x + "_error_" + (y + 1);
// write response content to file - no binary data are written
if (testURL.isAsciiContent())
{
FileOutputStream fout = new FileOutputStream(fileStartName + "_response_content.html");
fout.write(testURL.getDecompressedContent());
fout.close();
}
}
}
break;
case PerformanceDataRecord.TYPE_PAGE_BREAK:
break;
default:
break;
}
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
