如何在反应中绑定来自 API 的数据？

Question

I'm new in React.JS. I want to bind data from the API in a HTML code.
Here is a GET method with axios from the API:

componentDidMount() {
    var token = localStorage.getItem('accessToken');
    var config = {
        headers: { 'Authorization': "Bearer " + token }
    };
    var apiBaseUrl = "https://**********/";
    const that = this;
    axios.get(apiBaseUrl + 'api/Account/UserInfo', config)
        .then(function (response) {
            console.log(response.data);
            if (response.status === 200) {
                that.setState({ userInfo: response.data });
                console.log(that.state.userInfo.Email);
            }
            else {
                console.log(response.data);
            }
        })
        .catch(function (error) {
            console.log(error);
        });
}

The console shows me

{Email: "xxxxxxx@yahoo.com", HasRegistered: true, LoginProvider: null}

Now I want to display the email address in HTML. How can I do this?

Answer 1

Here you've set the state

 that.setState({ userInfo: response.data });

To access it - try this.state.userInfo.Email

You can put that into some html elements like this

<p>{this.state.userInfo.Email}</p>

Answer 2

In JSX you can show like this

render(){
  return (
    <p>{this.state.userInfo ? this.state.userInfo.Email : 'Email is not provided'}</p>
  )
}

Answer 3

in JSX you just define

render(){
const email = this.state.userInfo? this.state.userInfo.Email:'';
return(
  <div>{email}</div>
 )
}
