我已经尝试了各种不同的方法，但我被难住了。在 React 中使用 promise 和进行 api 调用的新手。这就是我目前所拥有的：

import React, { Component } from 'react'
import Column from './Column'
import { CardGroup } from 'reactstrap';

let api = "https://fcc-weather-api.glitch.me/api/current?";


class App extends Component {

    constructor(props) {
        super(props)
        this.state = {
            isLoaded: false,
            items: {},
        }

    this.fetchWeather = this.fetchWeather.bind(this)
}

fetchWeather(apiStr) {
    fetch(apiStr)
        .then(res => res.json())
        .then(

            (result) => {

                console.log(result)
                this.setState({
                    isLoaded: true,
                    items: result.main
                });
                console.log(this.state);
            },
            // Note: it's important to handle errors here
            // instead of a catch() …
