![对象作为React子对象无效（找到：[object Promise]）](http://www.mshxw.com/aiimages/31/608841.png "对象作为React子对象无效（找到：[object Promise]）")
this.renderPosts()将返回
Promise非实际数据，并且AFAIK Reactjs将不会在中隐式解析Promises
render。
你需要这样
componentDidMount() { this.renderPosts();}renderPosts = async() => { try { let res = await axios.get('/posts'); let posts = res.data; // this will re render the view with new data this.setState({ Posts: posts.map((post, i) => ( <li key={i} className="list-group-item">{post.text}</li> )) }); } catch (err) { console.log(err); }}render() { return ( <div> <ul className="list-group list-group-flush"> {this.state.Posts} </ul> </div> );}
