Question

我正在尝试找到一种方法来创建一个抽象层，以便在react-native中使用AysncStorage。我试图用const方法创建一个类，但是当我调用它时出现此错误：

DOMNodes from htmlparser2 Array [
  Object {
    "data": "Error Hapened: TypeError: _reactNative.default.setItem is not a function",
    "next": null,
    "parent": null,
    "prev": null,
    "type": "text",
  },

这是JS尝试访问AysncStorage的代码：

import AsyncStorage from 'react-native';

export const getClient = () => {
    return _retrieveData("loggedClient");
}
export const setClient = (client) => {
    _storeData("loggedClient", JSON.stringify(client));
}

export const clear = () => {
    AsyncStorage.clear();
}

_retrieveData = async (id) => {
    try {
        const value = await AsyncStorage.getItem("@App:"+id);
        if (value !== null) {
            // We have data!!
            console.log("found: " + id + "="+ value);
            return value;
        } else {
            console.log("Not found: " + id);
        }
    } catch (error) {
        console.log("Failure retrieving "+ id +" error: " + error)
    }
};

_storeData = async (id, value) => {
    try {
        await AsyncStorage.setItem('@App:'+id, value);
        console.log("saved");
    } catch (error) {
        console.log("Failure saving: " + error);
    }
};

关于如何在react-native中创建抽象类以与AsyncStorage进行交互的任何想法？

尝试将导入AysncStorage的方式更改为以下内容：

import { AsyncStorage } from 'react-native';

React-Native-为AsyncStorage创建抽象层
