HarmonyOS HCE命令行模式，如何读取传递的被测函数的参数？

onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void { 
  hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate'); 
  let customParams: Record<string, Object> | undefined = want.parameters 
  if (customParams != undefined) { 
  const s = Object.entries(customParams); 
  s.map((data) => { 
  hilog.info(0x00000, 'testTag', 'v:' + data.pop() + ",k:" + data.pop()); 
}) 
} 
}
