如何在React中使用unirest API调用?

标签: node.js reactjs unirest

我是第一次使用unirest API调用和React,但是在实现unirest调用时遇到了麻烦。虽然它可以在简单的Node.js程序中运行,但是如果我尝试将下面的代码插入React.js文件并使用它,由于某种原因,我将无法获得任何结果,因为我只是获得了一个未定义的对象

console description

var unirest = require('unirest');
unirest.get(--insert url here--)
.header("X-Mashape-Key", --insert key here--)
.header("X-Mashape-Host", "spoonacular-recipe-food-nutrition- 
v1.p.mashape.com")
.end(function (result) {
  console.log(result.status, result.headers, result.body);
});

但是,当我将其插入准系统Node.js文件中时,我会得到一个带有所需值的对象。我已经为此苦苦挣扎了好几天-有人知道我在做什么错吗?

编辑:这是我尝试在React中实现此方法的方法:

import React from 'react';
import './App.css';
var unirest = require('unirest');

class Kitchen extends React.Component {
  callApi() {
    unirest.get(--insert api url--)
    .header("X-Mashape-Key", --insert api key--)
    .header("X-Mashape-Host", "spoonacular-recipe-food-nutrition- 
    v1.p.mashape.com")
    .end(function (result) {
      console.log(result.status, result.headers, result.body);
  });  

  render() {
    return(
      <div className="ingredient-info">
        {this.callApi()}
      </div>
    )
  }

编辑2:这是预期的对象主体的外观:

[ { id: 556470,
    title: 'Apple fritters',
    image: 'https://spoonacular.com/recipeImages/556470-312x231.jpg',
    imageType: 'jpg',
    usedIngredientCount: 3,
    missedIngredientCount: 0,
    likes: 243 },
  { id: 73474,
    title: 'Apple Turnovers',
    image: 'https://spoonacular.com/recipeImages/73474-312x231.jpg',
    imageType: 'jpg',
    usedIngredientCount: 3,
    missedIngredientCount: 0,
    likes: 48 },
  { id: 47950,
    title: 'Cinnamon Apple Crisp',
    image: 'https://spoonacular.com/recipeImages/47950-312x231.jpg',
    imageType: 'jpg',
    usedIngredientCount: 3,

Unirest是针对Node(服务器端)的...客户端(浏览器)已在其中获取...

以下是https://randomuser.me/示例的简单获取请求:

class App extends Component {
  state = { users: [] };

  componentDidMount() {
    fetch("https://randomuser.me/api/?results=10&nat=us")
      .then(results => results.json())
      .then(data => {
        const users = data.results;
        this.setState({ users: users });
      })
      .catch(err => console.log(err));
  }

  render() {
    return (
      <div>
        {this.state.users.map((user, index) => {
          return (
            <div key={index}>
              <div>{user.name.first}</div>
              <img src={user.picture.thumbnail} alt="" />
            </div>
          );
        })}
      </div>
    );
  }
}
