[React] axios - TypeError: Cannot read property 'setSt

将内部的function 改成 es6的 箭头函数就可以解决

 componentDidMount() {  axios  .get(getBaseUrl()+`get`)  .then((response) => {    this.setState({name: "RESPONSE TEXT"});    //this.setState({name: response.data.name});  })  .catch((e) =>   {    console.error(e);  });  //this.setState({});}
