使用React和axios未能成功调用Deezer API [英] Failed call to Deezer API with React and axios

问题描述

我想连接到Deezer API并读取数据，该API在此处可用，如果您选择其中的第一个链接，然后在新标签页中打开，您将看到json中的数据，但是Axios无法退回它

I want to connect to Deezer API and read data, the API is available here, if you take first links they have there and open in a new tab you will see the data in json, however Axios can't return it

import React from "react";
import ReactDOM from "react-dom";

import axios from "axios";

import "./styles.css";

class App extends React.Component {

  componentDidMount() {
    axios.get("https://api.deezer.com/album/302127")
    .then(response => {
      console.log(response);
    })
    .catch(err => {
      console.log(err);
    });
  }

  render() {
    return (
      <div className="App">
        <h2>Deezer</h2>
      </div>
    );
  }
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

推荐答案

Deezer api不允许跨域请求.因此无法通过浏览器进行api调用.

Deezer api don't allow cross-origin request. So an api call from browser is not possible.

不过，您可以使用变通办法并使用 https://cors-anywhere.herokuapp.com

However you can use a workaround and use https://cors-anywhere.herokuapp.com

您需要像下面这样更改代码:

You need to change your code like following:

axios.get("https://cors-anywhere.herokuapp.com/https://api.deezer.com/album/302127")
  .then(response => {
    this.setState({ response })
  })
  .catch(err => {
    console.log('error', err);
  });

这是一个有效的示例: https://stackblitz.com/edit/react-v6bufu

Here is a working example: https://stackblitz.com/edit/react-v6bufu

但是，我建议您对自己的后端进行编码，以供调用 Deezer的API.您不会在那儿遇到跨域错误.

However, I will recommend to code your own backend where you will call Deezer's APIs. You won't be getting cross-origin error there.
