在react / redux中的store.subscribe中调用一个函数

Question

我想在store.subscribe内调用一个函数，但总是收到错误消息：undefined this，

这是我正在尝试的代码：

componentDidMount() {
  this.GetFilteredData();
}

GetFilteredData = () => {
  WithHoldTaxApi.GetFilteredData()
    .then((collection) => {
      console.log("data", collection)
      this.setState({ collection: collection })
    }
    ).catch(error => {
      throw error;
    })
}

store.subscribe(() => {
  console.log(store.getState())
  this.GetFilteredData();
})

我认为您需要执行以下操作：

componentDidMount() {
  this.subscribe();
}

GetFilteredData = () => {
  WithHoldTaxApi.GetFilteredData()
    .then((collection) => {
      console.log("data", collection)
      this.setState({ collection: collection })
    }
    ).catch(error => {
      throw error;
    })
}

subscribe = () => {
  store.subscribe(() => {
     console.log(store.getState())
     this.GetFilteredData();
  })
}
