分离的前后台交互

后台处理跨域

安装插件
>: pip install django-cors-headers

插件参考地址:https://github.com/ottoyiu/django-cors-headers/
项目配置:dev.py
# 注册app
INSTALLED_APPS = [
	...
	'corsheaders',
]

# 添加中间件
MIDDLEWARE = [
	...
	'corsheaders.middleware.CorsMiddleware',
]

# 允许跨域源
CORS_ORIGIN_ALLOW_ALL = True

# 允许的请求头
CORS_ALLOW_HEADERS = (
    "accept",
    "accept-encoding",
    "authorization",
    "content-type",
    "dnt",
    "origin",
    "user-agent",
    "x-csrftoken",
    "x-requested-with",

    # 额外允许的请求头
    'token',
)

前台请求Banner数据

修订Banner.vue
<template>
    <div class="banner">
<!--        <el-carousel height="400px">-->
<!--            <el-carousel-item v-for="item in 4" :key="item">-->
<!--                <img src="../assets/img/banner1.png" alt="">-->
<!--            </el-carousel-item>-->
<!--        </el-carousel>-->
        <el-carousel height="400px">
            <el-carousel-item v-for="banner in banner_list" :key="banner.title">
                <router-link :to="banner.link">
                    <img :src="banner.image" alt="">
                </router-link>
            </el-carousel-item>
        </el-carousel>
    </div>
</template>

<script>
    export default {
        name: "Banner",
        data() {
            return {
                banner_list: []
            }
        },

        // 在created钩子中
        created() {
            this.$axios({
                url: this.$settings.base_url + '/home/banners/',
                headers: {  // 测试前台给后台提交请求头
                    // authorization: 'jwt abc.def.xyz',
                    // token: 'jwt abc.def.xyz',
                }
            }).then(response => {
                console.log(response.data);
                this.banner_list = response.data;
            }).catch(error => {
                console.log(">>>", error);
            })
        }

    }
</script>

<style scoped>
    .el-carousel__item {
        height: 400px;
        min-width: 1200px;
    }
    .el-carousel__item img {
        height: 400px;
        margin-left: calc(50% - 1920px / 2);
    }
</style>
