Question

我有一个React应用程序向Rails API发出请求。用户签名的代码如下所示： “./actions/userActions”

export function signInUser(user){
var data = {email: user.email, password: user.password, remember_me: 
user.id};
return function(dispatch){
    dispatch({type: 'SIGN_IN_USER', payload: user})
    return fetch('https://fidirect-api.herokuapp.com/api/users/sign_in', {
    method: 'POST',
    headers: {
      Accept: 'application/json',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({user: data}),
    }).then(res => console.log(res))
    .catch(error => console.error('Error:', error))
    .then(response => console.log('Success:', response));
}
}

减速机看起来像这样：

export function usersReducer(state = {currentUser: {}, user_id: null}, action) {
switch (action.type) {

case 'SIGN_UP_USER':
  window.localStorage.setItem('id', 'action.id')
  return Object.assign({}, state, {currentUser: {id: action.id, email: action.email, password: action.password }, 
  user_id: window.localStorage.getItem('id') }) 
case 'SIGN_IN_USER': 
  return Object.assign({}, state, {currentUser: {id: action.payload.id, email: action.payload.email, password: action.payload.password }, user_id: current_user.id})
default:
  return state
}
}

这样可以正常工作，但我希望能够将存储在后端的用户ID（例如1,2,3,4等）保存到前端，以便将来在我请求特定用户的数据，我可以根据用户的ID过滤数据，这看起来像这样： “./reducers/assetsReducer”

case 'GET_ASSETS': 
  return {loading: false, assets: action.payload.filter((asset => asset.id === getState().usersReducer.user_id))};
default:
  return state;

}

如何在React中保留这样的用户ID？

Answer 1

您使用localstorage作为注册减速器（不确定原因）但您也可以这样做以登录。登录后将数据保存到localstorage，或者使用react store。

React Store

如何将用户的ID从Rails后端服务器持久保存到React前端服务器？
