asyncstorage

问题 I am using react-native and apollo client and if I try to set header by jwt stored in AsyncStorage, it seems not working. Other resolvers which doesn't need header works very well. My code is like below. import { ApolloClient } from "apollo-client"; import { InMemoryCache } from "apollo-cache-inmemory"; import { ApolloLink } from "apollo-link"; import { createHttpLink } from "apollo-link-http"; import AsyncStorage from "@react-native-community/async-storage"; const cache = new InMemoryCache()

问题 I have replicated an example to understand the testing of Mock-async-storage for reactjs. Any suggestions for a different approach of testing are welcome. I tried to replicate the use case from this stack overflow page : How to test Async Storage with Jest? but I couldn't figure out how that would fit for my sample case. So I tried the below npm module https://github.com/devmetal/mock-async-storage, but that didn't help either. Code written in Example.test.js import AsyncStorage from '@react

问题 My current project require me to store user data locally, So I use the AsyncStorage from react native itself.

问题 I'm trying to get an item from async storage. componentDidMount() { console.log('componentDidMount') AsyncStorage.getItem(STORAGE_KEY) .then(storage => console.log('then', storage)) .catch(err => console.log('catch', err)) } Also trying this way: componentDidMount() { console.log('componentDidMount') AsyncStorage.getItem(STORAGE_KEY, (err, data) => { console.log('data', data); console.log('err', err) }); } But no matter how I do it, the debugger is outputting only the componentDidMount log

问题 How do I set multiple values within Asyncstorge?.Because I'm trying to set token and user_id .These are the server response values. This is how response looks like json { error: 0, data: 'User registered Successfully', userData: { pwd: 'lmlmlm', phone_no: '9898989', user_name: '', status: 1, date: 2018-10-24T07:12:20.656Z }, user_id: 60, token: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.' } And in react native I've written like this after user registrtaion. .then((response) => response.json())

问题 I am using following code for storing and retrieving data. But it isn't working as I want. Setting data: async setDataFromApi(token, json) { const {goBack} = this.props.navigation; // Navigation let iext_inf = { token: token, userid: json.data.id, username: json.data.username, image: json.data.profile_picture, }; console.log(iext_inf); try { await AsyncStorage.setItem('iext_inf', JSON.stringify(iext_inf) ); // Stuck here goBack(); } catch (error) { console.log("Error"); } } Getting data:

问题 I'm trying to get information (true/false) from AsyncStorage in a function and create a string which is importent to fetch data in the next step. My problem is, the function is not finished until the string is required. I tried many solutions from the internet like async function and await getItem or .done() or .then(), but none worked out for me. The current behaviour is that the console displays first "channel required: " than "channel: channel_id0". 回答1: Aspects in your question are

问题 I'm using AsyncStorage.clear() which is working just fine on Android but when run using iOS platform (real device) I'm getting this error and can't find anything online about it.

问题 I am using AsyncStorage in my React Native application to store information about the user. The getItem() function is asynchronous and requires me to implement a callback when I want to load data from the storage system. AsyncStorage.getItem("phoneNumber").then((value) => { this.setState({"phoneNumber": value}); }).done(); Because retrieving a value from the storage does not take long, I would like to wait until the operation is complete before continuing execution. Is it possible to load
