Reactjs 函数无法正常工作

Question

我有这个函数发生器

  function* importWall(action) {
  const { mnemonic, password, num_addresses, address, navigation } = action;
  const network = yield select(getSelectedNetwork);
  const importedWallet = yield call(
    importAccount,
    mnemonic,
    password,
    num_addresses,
    network.name
  );

  const newAccount = {
    name: 'Account 1',
    password: action.password,
    nonce: 0,
    id: 0,
    address: importedWallet,
    mnemonic: action.mnemonic,
  };

  yield put(setUser(newAccount));
  yield addWallet({
    ...newAccount,
    active: true,
  });

  yield put(getWalletBalance(newAccount, network));
 
  if (address === undefined) {
    yield takeLatest(actionTypes.IMPORT_WALLET, importWall);
    console.log('w');
  } else {
    navigation.navigate('Main');
  }
}

除了我的条件语句外，一切正常，我尝试了几种方法，但如果地址未定义，我将无法再次调用此生成器。请就如何实现它提出任何建议？

你的 takeLatest 不应在效果处理程序中 'importWall'

function* runSagas () {
      yield takeLatest(actionTypes.IMPORT_WALLET, importWall);
}

Take latest 是一个 fork 效果，它启动类型 'IMPORT_WALLET' 的操作通道并将运行 importWall 来处理这些操作。您不需要从效果处理程序中重新（获取最新）。

如果你需要的是重试机制。然后简单地重新启动原来的动作。

if (address === undefined) {
   yield put(action);
 }
