項(xiàng)目中某個函數(shù)由于使用了switch-case語句，當(dāng)代碼增加到某個程度的時候，已進(jìn)入該函數(shù)，則程序跑飛。改成if結(jié)構(gòu)，則問題解決。

switch(packType)
{
case CMD_RANDOM_NUMBER:
return CmdRandomResponse(appData);
break;


case CMD_MUTEX_AUTH:
//return CmdMutexAuthResponse(appData);
break;


case CMD_OPEN_DOOR:
return CmdOpenDoorResponse(appData);
break;


case CMD_UPDATE_TIME:
//return CmdUpdateTimeResponse(appData);
break;


case CMD_READ_TIME:
//return CmdReadTimeResponse(appData);
break;


case CMD_WRITE_SN:
return CmdWriteSnResponse(appData);
break;


case CMD_WRITE_KEY:
return CmdWriteKeyResponse(appData);
break;


case CMD_DEVICE_BOND:
return CmdDeviceBondResponse(appData);
break;


case CMD_DEVICE_UNBOND:
//return CmdDeviceUnbondResponse(appData);
break;


case CMD_READ_BOND_INFO:
//return CmdReadBondInfoResponse(appData);
break;


case CMD_READ_VERSION:
//return CmdReadVersionResponse(appData);
break;


default:
break;
}
