可能的未处理的承诺拒绝（id：0）：错误：网络错误（Axios）

Question

我正在使用axios库来获取一些数据，出现此错误：

  Possible Unhandled Promise Rejection (id: 0):

我提取的代码是：

componentWillMount(){

        axios.get('https://rallycoding.herokuapp.com/api/music_albums')
            .then(response => {
                this.state.setState({albums: response.data});
                console.log(this.state.albums);
            })
            .then(error => console.log(error));
    }

Answer 1

我尝试过，它运行正常

axios.get('https://rallycoding.herokuapp.com/api/music_albums')
            .then(response => {
                this.setState({albums: response.data});
                //console.log(this.state.albums);
                console.log(response);
            })
            .then(error => console.log(error));

问题出在this.state.setState({albums: response.data});
