如何在标头中传递授权令牌以响应 Axios.post？

Question

我的 React、Express、MongoDB 应用程序。

我想为 Axios 发布请求传递带有标头的身份验证令牌。

但是，当我尝试通过它时，出现 403 错误（禁止）。

本地存储

在这里，我从本地存储中检索所有身份验证数据

export function authHeader() {
    // return authorization header with basic auth credentials
    let user = JSON.parse(localStorage.getItem('user'));

    if (user && user.token) {
        return { Authorization: `Bearer ${user.token}` };
    } else {
        return {};
    }
}

Axios.post

在这里，我正在调用 axios 发布请求

import React, { Component } from 'react'
import Axios from 'axios';
import { authHeader } from '../../../helpers'

export default class SubAdmin extends Component {
    constructor(props) {
        super(props)

        this.state = {
            user: {},
            users: [],
            error: null,
            isLoaded: false,
            items: []
        }
    };

    componentDidMount() {
        this.setState({
            user: JSON.parse(localStorage.getItem('user')),
            users: { loading: true }
        });
        Axios.post('http://localhost:4200/api/viewSubAdmin', 
                    {
                        headers: authHeader()
                    }).then(
          result => {
              console.log(result);

            this.setState({
              isLoaded: true,
              items: result.data
            });
          },
          error => {
            this.setState({
              isLoaded: true,
              error
            });
          }
          );
      }

Answer 1

Axios.post接收url 、 data和headers作为参数。 如果只传递url和headers ，则必须传递null作为data

axios.post(url, null, headers)

或者你可以试试Axios api

Axios({
    method: 'post',
    url: 'http://localhost:4200/api/viewSubAdmin',
    headers: authHeader()
}).then.....

Answer 2

你的代码有一点错误我已经修改了你的代码。 请用以下代码替换您的 axios 调用并检查

Axios.post('http://localhost:4200/api/viewSubAdmin',{
            headers: authHeader()
          }).then(result => {
              console.log(result)
              this.setState({
               isLoaded: true,
               items: result.data
              })
            }).catch(error => {
                this.setState({
                 isLoaded: true,
                 error
               })
              });
