内容 - 安全 - 政策问题(Content-Security-Policy issue)

 在我的档案中找到了这个。 不知道它何时被写入，是否有效，或者是否仍然支持此接口。 你没有说你正在使用的PSQL版本，所以我甚至不知道这是否适用于你的版本。 
 
import pervasive.database.*;

public class VersionTest implements Consts
{
public VersionTest()
{
try
{
Session session = Driver.establishSession(); 
Database db = session.connectToDatabase("PMKE:"); 
XCursor xcursor = db.createXCursor(57000); 
//Using local TABL.DAT (length 255 assures no leftovers!)
xcursor.setKZString(0,255,"plsetup\\tabl.dat");
//Open the file to load local MKDE
int status = xcursor.BTRV(BTR_OPEN);
System.out.println("Local Open status: " + status);
//Using remote TABL.DAT (length 255 assures no leftovers!)

xcursor.setKZString(0,255,"h:\\basic2c\\develop\\tabl.dat");
//set the buffer size
xcursor.setDataSize(15);
//get version 
status = xcursor.BTRV(BTR_VERSION);
System.out.println("Version status: " + status);
// should be 15, always prints 5
System.out.println("Version length: " + xcursor.getRecLength());
System.out.println("Version: " + xcursor.getDString(0,15));

// try with an open file on a server
XCursor xcursor2 = db.createXCursor(57000); 
//Using remote TABL.DAT (length 255 assures no leftovers!)

xcursor2.setKZString(0,255,"h:\\basic2c\\develop\\tabl.dat");
//Open the file
status = xcursor2.BTRV(BTR_OPEN);
System.out.println("Remote Open status: " + status);
//set the buffer size
xcursor2.setDataSize(15);
//get version 
status = xcursor2.BTRV(BTR_VERSION);
System.out.println("Version status: " + status);
// should be 15, always prints 5
System.out.println("Version length: " + xcursor2.getRecLength());
System.out.println("Version: " + xcursor2.getDString(0,15));

// clean up resources

Found this in my archives. Don't know when it was written, whether it works, or if this interface is still supported. You don't say what version of PSQL you're using so I don't even know if this will work with your version.
