1,先创建VUE项目: vue init webpack-simple test_test (test_test)项目名
2.进入项目目录下:cd test_test
3.下载补全依赖:cnpm install
4.下载vue-router: cnpm install vue-router --save
5.下载 axios:cnpm install axios --save
6.下载jquery: cnpm install jquery --save
7.检测项目是否创建成功:cnpm run dev
8.将请求地址封装起来,一边日后修改,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;
}
9.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)
