我需要帮忙解决这个错误

这是后端发来的消息：

Forbidden (Origin checking failed - http://localhost:3000 does not match any trusted origins.): /user/login/
[04/Mar/2024 18:17:23] "POST /user/login/ HTTP/1.1" 403 2568

这是我用来配置axios的react设置：

import axios from 'axios';


export const setCSRFToken = async () => {
    try {
        const response = await instance.get('/user/getCSRFToken/');
        const csrfToken = response.data.CSRFToken;
        instance.defaults.headers.common['X-CSRFToken'] = csrfToken;
        console.log(csrfToken)
        console.log('Headers actualizados:', instance.defaults.headers);
        axios.defaults.withCredentials = true;
    } catch (error) {
        console.error('Error al obtener el token CSRF:', error);
    }
};

export const instance = axios.create({
  baseURL: 'http://127.0.0.1:8000',
  timeout: 5000, // tiempo de espera de 5 segundos
  headers: {
    'Content-Type': 'application/json',
  },
});


// Llama a la función setCSRFToken para configurar el token CSRF al crear la instancia de Axios
setCSRFToken();

这是我的settings.py文件：

            <Footer />

    );
};

我已经尝试过实现一个带有csrf_exempt的get请求，提取令牌并在发送http请求时使用它，还配置了CORS_ALLOWED_ORIGINS以允许从'http://localhost:3000'发送请求，但我不知道还有其他解决办法。

django http请求 前端开发 csrf axios cors 403错误

我不知道你具体的问题是什么，但显然这是一个CORS的问题。这个问题在开发时很麻烦，尤其是当你的前端在另一个3000端口的服务器上时。为了避免这个问题，我在我的dev.py文件中设置了相关配置（这个文件是基于基础设置的.py文件扩展而来的）。不过，记住在生产环境中不要使用这个方法。在生产环境中，最好把前端构建成静态的.js文件，然后由同一个服务器提供服务，这样就不会有CORS的问题，因为前端和后端都是由同一个服务器提供的。

# Para que Django nos deje acceder desde el Dev Server de React, es necesario añadir:
CORS_ALLOWED_ORIGINS = (
    'http://localhost:3000', 'http://127.0.0.1:3000',
)
CSRF_TRUSTED_ORIGINS = ['http://localhost:3000', 'http://127.0.0.1:3000', ]
INSTALLED_APPS += ('corsheaders',)
MIDDLEWARE += ['corsheaders.middleware.CorsMiddleware',]
CORS_ORIGIN_ALLOW_ALL = True
CORS_ALLOW_CREDENTIALS = True
