HarmonyOS鸿蒙Next中使用MifareClassicTag.readSingleBlock方法读M1卡时，一直报3100204错误，读之前已经卡片已经验证成功，请问怎么解决？

这是代码，请查看一下，帮忙看看是哪里出了问题：

我的代码逻辑基本上和你上面说的一样，根据你说的做了调整，还是一样无法读出，请再帮忙看一下代码：

try {
  mifareClassic.connect()
  console.info("mifareClassic tag connect success");
} catch (businessError) {
  console.error("mifareClassic tag connect businessError: " + businessError);
}

// see 'tag.TagInfo' at 'js-apis-nfcTag.md', obtains the 'mifareClassic' correctly.
// byte[] keybyte = new byte[]{0x01, (byte) 0x11, (byte) 0x18,0x3F,0x12, (byte) 0x11};
// let key = [0x01, 0x11, 0x18, 0x3F, 0x12, 0x11]
try {
  let key =[0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF]
  let sectorCount : number = mifareClassic.getSectorCount();
  this.sectorCount = sectorCount // 扇区数
  for (let i = 0 ; i < sectorCount; i++) {
    mifareClassic.authenticateSector(i, key, true, (err : BusinessError) => {
      if (err) {
        console.error(`mifareClassic, 第${i}块扇区验证失败， errCode: ${err.code}, message: ${err.message}`);
      } else {
        console.info(`mifareClassic , 第${i}块扇区验证成功`);
        // 验证扇区成功 获取扇区的第一个块号
        let blockCount : number | undefined = mifareClassic?.getBlockCountInSector(i)
        if(blockCount != undefined){
          for(let j = 0 ; j < blockCount ; j++){
            mifareClassic?.readSingleBlock(j, (err : BusinessError, data : number[]) => {
              if (err) {
                console.error(`mifareClassic第${i}扇区,第${j}块 读取失败 : ${err.code},${err.name}`);
              } else {
                console.info(`mifareClassic第${i}扇区,第${j}块mifareClassic readSingleBlock AsyncCallback data: ${data}`);
              }
            });
          }
        }
      }
    });
  }
} catch (err) {
  console.error(`mifareClassic authenticateSector Promise errCode: ${err.code}, " + "message: ${err.message}`);
}

运行打印：

第二层for循环里面，读取数据时，你使用j直接读取，参考安卓代码：

`mifareClassic.readBlock(mifareClassic.sectorToBlock(i) + j);

鸿蒙nfc读写数据的api功能，基本与安卓的类似，你可以参考你原先安卓的读写代码，逻辑结构不用变，将api替换下名称替换下即可。你上面的代码，应该是有些问题。

安卓代码：

private void readM1Card(Tag tag) {
    MifareClassic mifareClassic = MifareClassic.get(tag);
    try {
        mifareClassic.connect();
        int sectorCount = mifareClassic.getSectorCount();
        for (int i = 0; i < sectorCount; i++) {
            if (mifareClassic.authenticateSectorWithKeyA(i, MifareClassic.KEY_DEFAULT)) {
                int blockCount = mifareClassic.getBlockCountInSector(i);
                for (int j = 0; j < blockCount; j++) {
                    byte[] data = mifareClassic.readBlock(mifareClassic.sectorToBlock(i) + j);
                    // 处理读取到的数据
                    String dataStr = new String(data);
                    Toast.makeText(this, "Sector " + i + ", Block " + j + ": " + dataStr, Toast.LENGTH_SHORT).show();
                }
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            mifareClassic.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

尝试下参考上面安卓代码，你的mifareClassic.authenticateSector之后，

  • let sectorCount : number = mifareClassic.getSectorCount();
  • 然后再进行for循环

在HarmonyOS鸿蒙Next中使用MifareClassicTag.readSingleBlock方法读取M1卡时，如果遇到3100204错误，可能的原因包括：

  1. 密钥验证问题：虽然卡片已经验证成功，但密钥可能不正确或与目标扇区不匹配。确保使用正确的密钥进行验证。

  2. 扇区或块号错误：提供的扇区或块号可能无效或超出范围。M1卡通常有16个扇区，每个扇区包含4个块。确保块号在有效范围内。

  3. 卡片状态问题：卡片可能处于不可读状态，如被锁定或损坏。确认卡片状态正常。

  4. 权限问题：某些块可能需要特定的权限才能读取。确认当前密钥具有读取该块的权限。

  5. 硬件或驱动问题：NFC读写器或驱动程序可能存在问题，导致无法正确读取卡片。检查硬件和驱动是否正常工作。

  6. API调用顺序问题：在调用readSingleBlock之前，确保已经正确初始化并选择了卡片。

  7. 系统或SDK版本问题：当前使用的HarmonyOS或SDK版本可能存在已知问题。检查是否有相关更新或补丁。

建议逐步排查上述可能的原因，确保每个环节都正确无误。

错误码3100204通常表示操作权限不足或卡片状态异常。建议您按照以下步骤排查：

  1. 确保卡片已正确验证，且使用的密钥与卡片匹配。

  2. 检查读卡器与卡片的连接是否稳定，避免信号干扰。

  3. 确认使用的块地址合法，且该块未被设置为不可读。

  4. 尝试重新初始化卡片，再进行读取操作。

如果问题依旧，建议查看HarmonyOS官方文档或联系技术支持获取更详细的指导。
