react-native-cli:2.0.1 反应本机:0.57.2 MacOS Mojave Axios,Redux
我可以在控制台上从数据库中读取和写入数据,但是我无法使用这些数据,因此我的代码看起来很不错,但是如果我只想获得Title的话?还是身体?
我要创建新动作吗?还是可以更改状态以用于代码?
有人可以帮助我提取正文或标题并将其放入移动应用程序中吗?
我的动作:
export function getPosts(){
const request = axios(`${FIREBASEBD}/posts.json`)
.then(response => {
let posts = [];
for(let key in response.data){
posts.push({
...response.data[key],
id:key
})
}
return posts;
})
return{
type:'GET_POSTS',
payload:request
}
}
我的输入数据:
import React, {Component} from 'react';
import {Platform, StyleSheet, Text, View, TextInput, Button} from 'react-native';
import { connect } from 'react-redux';
import { addPost, getPosts, getPost } from '../Stores/actions';
import { binActionCreators, bindActionCreators } from 'redux';
class InputData extends Component {
state = {
title: '',
body: ''
}
handleTitleInput = (title) => {
this.setState({title})
}
handleBodyInput = (body) => {
this.setState({body})
}
addPost = (state) => {
console.log('====================================');
console.log(this.state);
console.log('====================================');
this.props.addPost(this.state)
}
componentDidMount(){
console.log('====================================');
this.props.getPosts();
console.log('====================================');
}
render() {
return (
<View style={style.formContainer}>
<View style={style.InputWrapper}>
<Text>Title:</Text>
<TextInput
value={this.state.name}
style={style.input}
onChangeText={this.handleTitleInput}
/>
</View>
<View style={style.InputWrapper}>
<Text>Body:</Text>
<TextInput
value={this.state.body}
style={style.input}
onChangeText={this.handleBodyInput}
/>
</View>
<Button
title="Ajouter"
onPress={this.addPost}
/>
</View>
)
}
}
const style = StyleSheet.create({
input:{
padding: 5,
borderWidth: 1,
borderColor: 'lightgrey',
marginBottom: 5,
}
});
function mapStateToProps(state){
console.log('====================================');
console.log(state);
console.log('====================================');
cards: state.cards
}
function mapDispatchToProps(dispatch){
return bindActionCreators({addPost, getPosts, getPost}, dispatch)
}
export default connect(mapStateToProps, mapDispatchToProps)(InputData);
感谢您的帮助。 T。
