django+vue实现跨域的示例代码

pip install django-cors-headers

...
# Application definition
INSTALLED_APPS = [
    'django.contrib.staticfiles',

    'corsheaders',  # 添加：跨域组件
    'rest_framework',  # 添加：DRF框架
    'home',  # 子应用
]
MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware',  # 添加：放首行（放其他行未测试）
    'django.middleware.security.SecurityMiddleware',
    ...
# CORS组的配置信息
CORS_ORIGIN_WHITELIST = (
    'http://127.0.0.1:8080',
    # 这里需要注意： 1. 必须添加http://否则报错（https未测试） 2. 此地址就是允许跨域的地址，即前端地址
)
CORS_ALLOW_CREDENTIALS = True  # 允许ajax跨域请求时携带cookie

npm install axios -S

...
import axios from 'axios';  // 添加： 导入axios包

// axios.defaults.withCredentials = true;  // 允许ajax发送请求时附带cookie
Vue.prototype.$axios = axios; // 把对象挂载vue中

    created: function() {
      // 获取轮播图
      this.$axios.get("http://127.0.0.1:8000/book/").then(response => {
        console.log(response.data)
        this.banner_list = response.data
      }).catch(response => {
        console.log(response)
      })
     // http://127.0.0.1:8000/book/ 这个就是后端django接口
