在app.js已经提供store
```js
import React, { Component } from 'react';
import { Provider } from 'react-redux';
import Taro from '@tarojs/taro';
import dva from './dva';
import models from './models';
import * as user from './utils/user';
import configStore from './store'
import './app.scss'
// const store = configStore()
const dvaApp = dva.createApp({
initialState: {},
models: models,
onError(e, dispatch) {
console.log('系统出错了!');
// dispatch(action("sys/error", e));
},
});
const store = dvaApp.getStore();
class App extends Component {
componentDidMount () {}
componentDidShow () {
user.checkLogin().then(res => {
}).catch(() => {
console.log('not login');
Taro.navigateTo({
url: '/pages/login/index'
});
});
}
componentDidHide () {}
componentDidCatchError () {}
render () {
return (
<Provider store={store}>
{this.props.children}
</Provider>
)
}
}
export default App
错误
react.ts:53 Invariant Violation: Could not find "store" in either the context or props of "Connect(Index)". Either wrap the root component in a <Provider>, or explicitly pass "store" as a prop to "Connect(Index)".
