一、搜索后台接口

# 咱们写的很简单，但是公司中这个接口是最牛逼的
	-搜索接口中带个性化推荐
    
    
# 咱们只写了实战课，搜索要搜索所有跟用户输入相关的
	-实战课
    -轻课
    -免费
    -资料 文档

1.1 视图类

# 搜索接口，搜索就是查询所有，带过滤   按课程名搜索
class SearchCourseView(GenericViewSet, ListModelMixin):
    queryset = Course.objects.filter(is_delete=False, is_show=True).order_by('orders')
    serializer_class = CourseSerializer
    # 分页
    pagination_class = CommonPagination
    # 过滤，使用模糊匹配
    filter_backends = [SearchFilter]
    search_fields = ['name', 'brief']  # 1 brief内容非常多，如果使用mysql的搜索，like 全文搜，随着数据量越来越大，搜索越来越慢--->分布式全文检索引擎elasticsearch
    
    # 2 有很多课程，免费课，轻课，文档...，重写list方法
    # def list(self, request, *args, **kwargs):
    #     res=super().list(request, *args, **kwargs)
    #     actual_course=res.data.data   # [{},{}]
    #     free_course=[{},{},{}]
    #     light_course=[{},{},{}]
    #     others=[{},{},{}]
    #     return APIResponse(actual_course=actual_course, free_course=free_course, light_course=light_course, others=others)

1.2 路由

router.register('search', SearchCourseView, 'search')

二、搜索导航栏

Header.vue div下面

html

<!-- 搜索组件 -->
<form class="search">
    <div class="tips" v-if="is_search_tip">
        <span @click="search_action('Python')">Python</span>
        <span @click="search_action('Linux')">Linux</span>
    </div>
    <input type="text" :placeholder="search_placeholder" @focus="on_search" @blur="off_search"
           v-model="search_word">
    <el-button icon="el-icon-search" circle @click="search_action(search_word)"></el-button>
</form>

js

<script>
    export default {
        data() {
            return {
                is_search_tip: true,
                search_placeholder: '',
                search_word: ''
            }
        },
        methods: {
            search_action(search_word) {
                if (!search_word) {
                    this.$message('请输入要搜索的内容');
                    return
                }
                if (search_word !== this.$route.query.word) {
                    this.$router.push(`/course/search?word=${search_word}`);
                }
                this.search_word = '';
            },
            on_search() {
                this.search_placeholder = '请输入想搜索的课程';
                this.is_search_tip = false;
            },
            off_search() {
                this.search_placeholder = '';
                this.is_search_tip = true;
            },
        },
    }
</script>

css

<style scoped>
.search {
    float: right;
    position: relative;
    margin-top: 22px;
    margin-right: 10px;
}

.search input, .search button {
    border: none;
    outline: none;
    background-color: white;
}

.search input {
    border-bottom: 1px solid #eeeeee;
}

.search input:focus {
    border-bottom-color: orange;
}

.search input:focus + button {
    color: orange;
}

.search .tips {
    position: absolute;
    left: 0;
}

.search .tips span {
    border-radius: 11px;
    background-color: #eee;
    line-height: 22px;
    display: inline-block;
    padding: 0 7px;
    margin-right: 3px;
    cursor: pointer;
    color: #aaa;
    font-size: 14px;

}

.search .tips span:hover {
    color: orange;
}
</style>

三、搜索结果页面

配置路由

router/index.js

import Search from "@/views/Search.vue";

const routes = [
    // ...
    {
        path: '/course/search',  // 搜索页面路由
        name: 'search',
        component: Search
    },
];

Search.vue页面组件

<template>
    <div class="search-course course">
        <Header/>
        <!-- 课程列表 -->
        <div class="main">
            <div v-if="course_list.length > 0" class="course-list">
