[Python知识库]Django第四次培训

在__init__.py导入pymysql

?在setting.py文件中连接自己的MySQL数据库

?填写上?ALLOWED_HOSTS =[‘*’]可以使所有的网址都能访问Django项目

设置路由

一级路由
from django.contrib import admin
from django.urls import path, include
from app01 import urls as app01_urls
urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('app01.urls')),
    path('app01/', include(app01_urls, namespace='app01')),
]

二级路由

path('Appreap1/', Appreap1.as_view()),

在models.py中建表

?在终端执行表迁移

1. python manage.py makemigrations

2. python manage.py migrate

?在views.py中写函数

class Appreap1(APIView):
    def post(self, request):
        result = Employee.objects.filter(FIRST_NAME='1')
        arr = []
        for i in result:
            content = {'姓': i.FIRST_NAME, "名": i.LAST_NAME, '年龄': i.AGE, '性别': i.sex, '收入': i.INCOME}
            arr.append(content)
            print(arr)
            FIRST_NAME = request.data.get('FIRST_NAME')
            print(FIRST_NAME)
            return HttpResponse(arr)

前端hml代码

<div id="wrapper">
    <div id="div1">
        <div id="div2">
            <div id="div3"></div>
            <div id="div4">
                <text id="text3">HelloWorld</text>
                <button id="btn" onclick="onClick">请求响应</button>
            </div>
            <div class="back">
                <text>{{winfo}}</text>
            </div>
        </div>
    </div>
</div>

前端js代码

import qs from 'querystring'
import fetch from '@system.fetch'
export default {
    data:{
        winfo:"",
    },
    onClick(){
        fetch.fetch({
            url:'http://127.0.0.1:8000/app01/Appreap1/',
            data:qs.stringify({
                'FIRST_NAME':'1'}),
            responseType:"json",
            method:"POST",
            success:(resp)=>{
                this.winfo = resp.data;
                console.log("返回数据："+this.winfo)
            },
            fail:(resp)=>{
                this.winfo = resp.data;
                console.log("获取数据失败："+this.winfo+resp)
            }
        });
    },
}

'querystring'会报错，需要安装配置node.js和nmp

在前端的终端执行npm install qs 和 npm install querystring

启动django

再运行前端

结果
