node.js - react /Redux : Need help render API Response

Question

我正在开发一个食谱应用程序。我正在使用 Yummly API，我收到了响应，但是我很困惑如何呈现从 API 返回的数据，因为响应是一个带有食谱数组的对象。当我尝试渲染数组时出现此错误:

Uncaught (in promise) Error: Objects are not valid as a React child (found: object with keys {imageUrlsBySize, sourceDisplayName, ingredients, id, smallImageUrls, recipeName, totalTimeInSeconds, attributes, flavors, rating}). If you meant to render a collection of children, use an array instead.

链接到 API 响应的图像:

Object from API“匹配”是我想要在组件中渲染的部分

Action.js

import Axios from 'axios';
import {LOOK_UP_RECIPE`enter code here`} from './types';

 const API_ID = '########';
 const API_KEY = '######';
 const ROOT_LOOK_UP_URL = `http://api.yummly.com/v1/api/recipes? 
 _app_id=${API_ID}&_app_key=${API_KEY}`


export function lookuprecipesYummly(ingredients) {
 const yummlyurl =`${ROOT_LOOK_UP_URL}&q=${ingredients}`; 
 const request = Axios.get(yummlyurl);

return {
    type: LOOK_UP_RECIPE,
    payload: request
};
}

Reducer.js

import { LOOK_UP_RECIPE } from '../actions/types'
export default function(state = [], action) {
 console.log(action)
 switch (action.type){
    case LOOK_UP_RECIPE:
        return [ action.payload.data, ...state ];
 default:
    return state;
 }
}

组件:

    import _ from "lodash";
    import React, {Component} from 'react';
    import { connect } from 'react-redux';

class RecipeList extends Component {

 renderRecipe(recipeData) {
    return (
        <tr key={0}>
            <td key={1}>{recipeData.matches}</td>
        </tr>
    )
}

render() {

    return(
        <table>
            <thead>
                <tr key={1}>
                    <th>Recipe</th>
                </tr>
            </thead>
            <tbody>
                {this.props.recipes.map(this.renderRecipe)}
            </tbody>
        </table>
    )
}
}


function mapStateToProps({recipes}) {
   return {
       recipes
      }
};


export default connect(mapStateToProps)(RecipeList);

您需要使用一些 JSX 中每个配方的数据。以下是如何填充表行的示例:

import _ from "lodash";
import React, {Component} from 'react';
import { connect } from 'react-redux';

class RecipeList extends Component {

    renderRecipe(recipe) {
        return (
            <tr key={recipe.id}>
                <td>{recipe.recipeName}</td>
                <td>{recipe.rating}</td>
                <td>{recipe.attributes.course[0]}</td>
                <td>{recipe.ingredients.join(', ')}</td>
            </tr>
        )
    }

    render() {

        return(
            <table>
                <thead>
                    <tr>
                        <th>Recipe</th>
                        <th>Rating</th>
                        <th>Course</th>
                        <th>Ingredients</th>
                    </tr>
                </thead>
                <tbody>
                    {this.props.recipes.matches.map(this.renderRecipe)}
                </tbody>
            </table>
        )
    }
}


function mapStateToProps({recipes}) {
    return { recipes }
};


export default connect(mapStateToProps)(RecipeList);
