Codeigniter 4 验证总是失败

如何解决Codeigniter 4 验证总是失败

我正在尝试验证动态 html 字段，但验证总是失败。第一个例子是返回错误信息 “dynmic_field[0] 字段是必需的” 但第二个例子根本不起作用，它没有返回任何错误或得到验证

    // write PACK:
    mifareUltralight
        .writePage(
            pageOffset: 44,data: Uint8List.fromList([pack[0],pack[1],0]))
        .then((value) {
      setState(() {
        messageTXT = 'write PACK';
      });
    });

    // write PWD:
    mifareUltralight
        .writePage(
            pageOffset: 43,data: Uint8List.fromList([pwd[0],pwd[1],pwd[2],pwd[3]]))
        .then((value) {
      setState(() {
        messageTXT = 'write PWD';
      });
    });
    //set PROT
    bool prot =
        false; // false = PWD_AUTH for write only,true = PWD_AUTH for read and write
    int authlim = 0;
    // value between 0 and 7
    mifareUltralight
        .transceive(
            data: Uint8List.fromList([
      0xA2,// WRITE
      42,// page address
      ((object[0] & 0x078) | (prot ? 0x080 : 0x000) | (authlim & 0x007)),object[1],object[2],object[3]
    ]))
        .then((value) {
      setState(() {
        messageTXT = 'PWD_AUTH for write only0';
      });
    });

    // set AUTH0
    int auth0 = 0x00;
    // value between 0 and 7

    mifareUltralight
        .writePage(
            pageOffset: 41,data: Uint8List.fromList([
              object1[0],// keep old value for byte 0
              object1[1],// keep old value for byte 1
              object1[2],auth0
            ]))
        .then((value) {
      setState(() {
        messageTXT = 'PWD_AUTH for write only2';
      });
    });
  }

mifareUltralight
        .transceive(
            data: Uint8List.fromList([0x1B,pwd[0],pwd[3]]))
        .then((value) {
      if ((value != null) && (value.length >= 2)) {
        Ndef ndef = Ndef.from(tag);

        try {
          NdefMessage message = NdefMessage([
            NdefRecord.createUri(Uri.parse(url)),]);
          ndef.write(message).then((value) {
            print('write success');
          });
        } catch (e) {
          print(e.toString());
        }
      }
    });
