使用axios映射卡片向elasticsearch发送请求

Question

我有一个前端反应应用程序，有卡片，搜索栏，和过滤器。因此，为了映射我拥有的卡片，我想发送一个请求到elasticsearch (端口:9200)，使用axios将所有数据保存在数组中，并按我想要的方式映射我的卡片，您能帮我吗？

编辑:我在这里更新代码并包含所有代码，但是没有卡片映射的

    function CreateCards(NCARMap) {
    return(
        <SimpleCard
        key={NCARMap.id}
        theCardId={NCARMap.id}
        cardType={NCARMap.approvetool}
        cardNum={NCARMap.num}
        cardName={NCARMap.name}
        cardDate={NCARMap.date}
        // cardCategory={NCARMap.cardCategory}
        // cardSource={NCARMap.cardSource}
        cardDesc={NCARMap.summary}
        cardURL={NCARMap.image}
        />
    );

}

//create the class
export default class OfficialDocument extends Component {
  constructor(props) {
    super(props);

    this.state = { 
      NCARMap: [],
      NCARMapAS: [],
    };
  }
  componentDidMount(){
    //Get NCARMap data, NCARMapAS used for filtring and sorting the cards
    axios.get('http://localhost:9200/ncar_index/ncar/_search')
        .then(resp => {
            console.log(resp)
            this.setState({
              NCARMap: resp._source, 
              NCARMapAS:resp.data
        })
        console.log(this.state.NCARMap)
    })
}
  handleChange(event) {
    const search_query = event.target.value;

  }

    render(){
        return(

Answer 1

我的回答是把它们当作对象来接收：

代码

      <div className="general-card1">
        {this.state.noPlaceFound ? (
          <h3 className="noPlaceFound">
            <i className="fas fa-exclamation-circle fa-sm WarnIcon"></i>
            لا يوجد نتائج
          </h3>
        ) : (
          this.state.TweetsMap.map((v) => CreateCards(v._source))
        )}
      </div>

Answer 2

需要将呈现方法添加到类组件中。

export default class OfficialDocument extends React.Component {
  constructor(props) {
    super(props);

    this.state = {
      NCARMap: [],
      NCARMapAS: [],
      // need to add status
      status: 'idle',
    };
  }
  componentDidMount() {
    //Get NCARMap data, NCARMapAS used for filtring and sorting the cards
    this.setState({
      status: 'pending',
    });
    axios
      .get('http://localhost:9200/ncar_index/ncar/_search')
      .then((resp) => {
        console.log(resp);
        this.setState({
          NCARMap: resp._source,
          NCARMapAS: resp.data,
          status: 'success',
        });
        console.log(this.state.NCARMap);
      })
      .catch(() => {
        this.setState({
          status: 'error',
        });
      });
  }

  render() {
    return (
      <div>
        {this.state.status === 'pending' && <div>Loading...</div>}
        {this.state.status === 'error' && <div>Error</div>}
        {this.state.status === 'success' && this.NCARMap.map((item) => {
          return <CreateCards key={id} {...item} />;
        })}
      </div>
    );
  }
}
