我第一次使用React时遇到了一些麻烦.我在我的项目中编写了一个简单的类:

import React, { Component } from 'react';
import axios from 'axios';
import logo from './logo.svg';
import './App.css';

class FigosTest extends React.Component {
  state = {
    provider: 'unknown',
    date: 'sometime'
  };

  componentDidMount() {
    axios.get('x.com/some_api')
      .then(res => {
        console.log(res.data.provider);
        console.log(res.data.date);
        this.setState(this.setState(res.data));
        console.log("After");
        console.log(this.state.provider);
        console.log(this.state.date);
      });
  }

  render() {
    return this.provider || 'undefined';
  }
}

class App extends Component {
  render() {
    return (
      <div className="App">
        <header className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <p>
            Result: <FigosTest/>
          </p>
        </header>
      </div>
    );
  }
} …
