Reactjs 如何使用承载调用 magento 2 api（服务器响应状态为 401（未授权））

Question

我尝试使用 reactjs（来自 localhost:80）调用 (http://m2.example.com:80) magento 2 api，但它只有 return 错误：服务器响应状态为 401（未授权）

import React from "react";
import ReactDOM from "react-dom";
class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      error: null,
      isLoaded: false,
      items: []
    };
  }

  componentDidMount() {
    fetch("http://m2.example.com/rest/V1/products?searchCriteria[page_size]=20",{
        method: 'GET',
        mode: 'no-cors',
        credentials: 'include',
        withCredentials: true,
    headers: {
        'Authorization': 'Bearer 3nsi1y7pcun1atvhs87dxmokymquofii', 
        'Content-Type': 'application/json'
    }
    
})
      .then(res => res.json())
      .then(
        (result) => {
          this.setState({
            isLoaded: true,
            items: result.items
          });
        },
        // Note: it's important to handle errors here
        // instead of a catch() block so that we don't swallow
        // exceptions from actual bugs in components.
        (error) => {
          this.setState({
            isLoaded: true,
            error
          });
        }
      )
  }

  render() {
    const { error, isLoaded, items } = this.state;
    if (error) {
      return <div>Error: {error.message}</div>;
    } else if (!isLoaded) {
      return <div>Loading...</div>;
    } else {
      return (
        <ul>
          {items.map(item => (
            <li key={item.name}>
              {item.name} {item.price}
            </li>
          ))}
        </ul>
      );
    }
  }
}
/*const App = () => (
   <div>
     <h1>Hello world!!</h1>
   </div>
   )*/

   
ReactDOM.render(<MyComponent/>, document.getElementById("root"));
//ReactDOM.render(<App/>, document.getElementById("root1"));

有人知道上面的代码有什么问题吗？

Answer 1

尝试删除 mode: 'no-cors' 和 'withCredentials: true' 并从后端处理 CORS php magento2 - 请查看此 link 如何操作

fetch("http://m2.example.com/rest/V1/products?searchCriteria[page_size]=20",{
        method: 'GET',           
        credentials: 'include',
    headers: {
        'Authorization': 'Bearer 3nsi1y7pcun1atvhs87dxmokymquofii', 
        'Content-Type': 'application/json'
    }

之后它应该可以工作了。
