使用django和vue进行数据交互

一、前端请求的封装

1.将请求地址封装起来，以便日后修改，在src/assets/js目录下创建getPath.js文件

export default function getUrl(str) { 　　let url = 'http://localhost:8000/' + str; 　　return url; }

2.在同一个目录下创建axios.js文件

我的前端数据交互使用的模块使用的是axios

import axios from 'axios' import getUrl from './getPath' export default { Get: (config) => { axios({ methods: "get", url: getUrl(config.url), params: config.params }).then((res) => { stateDetection(res); config.callback && config.callback(res); }) }, Post: () => { axios({ methods: "post", url: getUrl(config.url) }).then((res) => { stateDetection(res); config.callback && config.callback(res); }) } } //状态检测
let stateDetection = (data, callback) => { let status = data.status_code; switch (status) { case 102: break; case 103: alert(data.content); break; case 404: window.location.href = data.url; break; } }

二、前端Get请求使用

1.在src/store/目录下的ArchiveStore.js文件引入axios模块

import axios from '../assets/js/axios'

2.在src/store/目录下的ArchiveStore.js文件里的state添加文章详情的数据结构

 specific: { browse: 0, content: '', title: '', date: '', tags: [] }, //文章详情

3.在src/store/目录下的ArchiveStore.js文件里创建一个action方法

        getArticlesSpecific({ commit, state }, id) { //得到指定文章详情 axios.Get({ url: 'get_article_specific', params: { id: id }, callback: (res) => { // console.log(res);
                    let data = res.data state.specific = { browse: data['browse'], content: data['content'], title: data['title'], date: data['date'], tags: data['tags'] } state.loading = false; // specific
 } }) }

4.在文章详情页面Specificartical.vue(src/components)下执行getArticlesSpecific方法即可

<template>
    <div class="specificartical borderStyle container" >
        <h1 class='title'>{{specific.title}} </h1>
        <div class='content'>
             <div><span class='annotation'><i></i>{{specific.date}}</span>/
            <span class='annotation'><i></i>{{specific.browse}}</span>/
            <div>{{specific.content}}</div>
            <div class='attention'><i>@</i></div>
            <div class='lable'><i>*</i><a v-for="(tag,index) in specific.tags" :key="index">{{index!=0?',':''}}{{tag}}</a></div>
        </div>
       
    </div>
</template>

<script> import {mapState, mapActions} from 'vuex' export default { name: 'specificartical', computed: { ...mapState({ specific:state=>state.ArchiveStore.specific, }) }, methods:{ ...mapActions([ 'getArticlesSpecific' ]), }, activated:function(){this.getArticlesSpecific(this.$route.params.id); } } </script>

在这里要注意的是使用activated生命周期函数，该函数会在keep-alive，组件被激活时调用

三、后端Get请求使用

1.在urls.py(djangoBlog)文件下面引入views.py里面的方法

from blog.views import *

2.注册url

from blog.views import * urlpatterns = [ url(r'^get_article_specific/$', getArticleSpecific, name='get_article_specific'), ]

3.在views.py里面导入需要用到的模块和models

 

from blog.models import *
from django.http import JsonResponse from django.db.models.functions import TruncDate

 

4.在views.py里面添加getArticleSpecific方法

#得到文章详情 def getArticleSpecific(request): results={} #得到标签数组 temp=list(Article.objects.get(id=request.GET['id']).tag.values_list('name') ) results['tags']=[] #处理标签数组的格式 for value in temp: results['tags'].append(value[0]) #得到文章详情 data=Article.objects.annotate(date=TruncDate('create_time')).values('title','content','browse','date').get(id=request.GET['id']) results['browse']=data['browse'] results['title']=data['title'] results['content']=data['content'] results['date']=data['date'] results['status_code']=102
    return JsonResponse(results, safe=False)
