Forbidden 403 前端与 django python 后端发生反应

问题描述 投票：0回答：2

我需要有关此错误的帮助

这是来自后台的消息：

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 axios 的 mi React 配置：

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();

};

我已经尝试使用 csrf_exempt 实现对视图的 get 请求，提取令牌并在发送 http 请求时使用它，配置 CORS_ALLOWED_ORIGINS 以允许从“http://localhost:3000”发送请求，我不知道任何其他解决方案

python reactjs django-csrf

我不知道为什么是你的问题的确切根源，但显然是一个 CORS 问题，配置开发由端口 3000 中的另一台服务器提供服务的前端是一个真正的头痛。我在我的 dev.py 中设置了这个（它扩展了基本设置） .py）以避免这种情况。不要在 prod 中使用它，在 prod 中最好构建前端并像静态 .js 一样提供它，这样您就不会遇到 CORS 问题，因为前端与后端一样由同一台服务器提供服务。

# 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
