Question

所以我的问题很容易解释，我试图从此api https://www.youtube.com/watch?v=NT45HE7L7yk获取数据。现在一切正常，但是我不知道如何在此API中获取图片。当我尝试获取图片时，我得到的链接与图片本身相反。我想我需要以某种方式在循环内使用src标记，但我不确定如何实现。我将在下面发布我的代码，一如既往，感谢您的帮助，因为我喜欢学习更多有关react的知识。

import React, {Component} from 'react';

class App extends Component{
    constructor(props){
        super(props);
        this.state = {
            items:[],
            isLoaded: false
        };
    }

    componentDidMount(){
      fetch('https://www.hatchways.io/api/assessment/students')
          .then(res=> res.json())
          .then(({ students }) => {
              this.setState({
                  isLoaded: true,
                  items: students,
              })
          });
  }

    render(){
        const {isLoaded, items} = this.state;
        if(!isLoaded){
            return <div>loading data...</div>;
        }

        else{           

            return(
                <div className="Data">
                    <div>
                        {items.map(item=>(
                            <p key={item.id}>
                                 name:{item.firstName +' '+ item.lastName +' '} |
                                 City:{item.city} |
                                 company:{item.company} |
                                 email:{item.email} |
                                 id:{item.id}|
                                 picture:{item.pic}

                            </p>

                        ))};
                    </div>



                </div>

            );
        }

    }

}

export default App;

Answer 1

当我尝试获取图片时，我得到的链接与图片本身相反。

<p key={item.id}>
     name:{item.firstName +' '+ item.lastName +' '} |
     City:{item.city} |
     company:{item.company} |
     email:{item.email} |
     id:{item.id}|
     picture:{item.pic} <<<<<<< You just print it as text.
</p>

要显示URL中的图像，请使用img标签。

<img src={item.pic}/>
