使用搜索栏从 API 获取数据

Get data from API with Search Bar

export class Diet extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [],
      searchValue: "",
    };
  }
  updateSearch = (value) => {
    this.setState({ searchValue: value });
    if (value.trim() !== "") {
      axios
        .get(
          `https://api.spoonacular.com/food/products/search?apiKey=1234&query=${value}&number=100`
        )
        .then((res) => {
          this.setState({ data: res.data });
        })
        .catch((error) => {
          console.log(error.response.data);
        });
    } else {
      setState({ data: [] });
    }
}}

  render() {
    const {
      data,
      searchValue,
    } = this.state;


    return (
          <SearchBar
            placeholder="Search Food..."
            onChangeText={this.updateSearch}
            value={searchValue}
            <List style={{ paddingTop: hp("2%") }}>
              <TouchableOpacity>
                {this.state.data.map(({ type }) => (
                  <Text>{this.state.type.products.title}</Text>
                ))}
              </TouchableOpacity>
            </List>

嗨,我正在尝试使用 SearchBaraxios 从 Spoonacular API 获取数据,当我 运行 代码时出现以下错误: undefined is not a function (near '...this.state.data.map...')

我认为您的问题是您正在尝试使用

FlatList

替换您的地图

<FlatList
        data={this.state.data}
        renderItem={({ item }) => (
                  <Text>{item.products.title}</Text>
                ))}
        keyExtractor={item => item.id}
/>
