请求代码：

export class LogInContainer extends Component {

  submit = (values) => {
    const { mutate } = this.props;
    mutate({
      variables: {
        email: values.email,
        password: values.password,
      },

我正在尝试在货币转换器应用程序中使用 RTK 查询。这个应用程序是基于2个API。

首先，我正在获取一个带有货币的对象。然后，我获取一系列国家/地区并对其进行过滤，具体取决于该国家/地区是否拥有该种货币。

商店代码：

export const store = configureStore({
  reducer: {
    [currenciesAPI.reducerPath]: currenciesAPI.reducer,
    [countriesAPI.reducerPath]: countriesAPI.reducer,
  },
  middleware: (getDefaultMiddleware) =>
    getDefaultMiddleware().concat(currenciesAPI.middleware, countriesAPI.middleware)
})

API代码：

export const currenciesAPI = createApi({
  reducerPath: 'currenciesAPI',
  baseQuery: fetchBaseQuery({ baseUrl: 'https://api.frankfurter.app'}),
  endpoints: (build) => ({
    fetchAllCurrencies: build.query<Currencies, void>({  
      query: () => ({
        url: '/currencies'
      }),
    })
  })
})

export const countriesAPI = createApi({
  reducerPath: 'countriesAPI',
  //tagTypes: ['Country'],
  baseQuery: fetchBaseQuery({ baseUrl: 'https://restcountries.com/v3.1'}),
  endpoints: (build) => ({
    fetchAllCountries: build.query<TransformedCountries[], string>({  
      query: () => ({
        url: '/all'
      }),
      transformResponse: …
